That distinction matters more than ever. Over recent years, Tier 1 contractors have progressively tightened their supply chain requirements. Where Silver was once sufficient to appear in procurement searches, many major contractors — Balfour Beatty, Kier, Morgan Sindall, Willmott Dixon, and others — now specify Gold as the minimum for inclusion in their approved supplier lists. If you are tendering for work through Tier 1 supply chains or larger public-sector frameworks, Gold is increasingly the entry ticket, not the premium option.

This guide covers what Constructionline Gold requires beyond Silver, how the assessment works, what it costs, and how to prepare an application that passes first time.

For a broader overview of how Constructionline fits alongside CHAS and SafeContractor, see our scheme comparison guide.

Silver, Gold, and Platinum: What Changes at Each Level

Constructionline operates three tiers. Each builds on the one below.

Silver

Silver covers the baseline: company verification, financial assessment (via Dun & Bradstreet), insurance verification, and a health and safety assessment aligned to the SSIP Common Assessment Standard. Silver satisfies the core SSIP requirements and places you on the Constructionline register, visible to buyers searching for prequalified suppliers.

Silver is a solid starting point for SMEs entering the register. But it only covers health and safety and financial standing. It does not address the broader compliance areas that Tier 1 contractors and public-sector frameworks increasingly require.

Gold

Gold adds four assessment areas on top of Silver:

• Environmental management
• Quality management
• Equal opportunities and diversity
• Anti-bribery and corruption

These are not optional add-ons. At Gold level, all four must be assessed and passed. This is the tier most commonly specified by Tier 1 contractors and larger public-sector buyers, and it aligns closely with the assessment scope of PAS 91 prequalification questionnaires (see our PAS 91 guide for more detail on that framework).

Platinum

Platinum extends into corporate social responsibility and behavioural assessment. It is less commonly required for SMEs but relevant for contractors working on major frameworks or with clients who prioritise social value.

For most construction SMEs with 5 to 50 employees, Gold is the target tier. It opens the widest range of opportunities without requiring the additional investment of Platinum.

What Constructionline Gold Requires: The Six Assessment Areas

1. Health and Safety

The health and safety assessment at Gold level is the same as Silver — aligned to the SSIP Common Assessment Standard. You need a current, director-signed health and safety policy; activity-specific risk assessments; method statements for high-risk work; evidence of competent H&S advice (in-house or external); training records (CSCS, SMSTS/SSSTS, trade-specific qualifications); accident and incident reporting procedures; and current insurance certificates.

If you already hold CHAS, SafeContractor, or another SSIP member scheme accreditation, Constructionline may recognise this through SSIP mutual recognition for the health and safety component. However, you still need to complete the full Constructionline registration and the additional Gold-level modules. For more on how SSIP mutual recognition works, see our SSIP guide.

2. Financial Assessment (Dun & Bradstreet)

Constructionline uses Dun & Bradstreet (D&B) financial data to assess your business's financial standing. This is not a pass/fail in the traditional sense — D&B assigns a financial risk rating based on your filed accounts, payment history, CCJs, and other credit data. This rating is visible to buyers on the register.

What this means in practice: your Companies House filings need to be up to date. If you have outstanding CCJs, late-filed accounts, or a thin credit history, these will affect your D&B rating and may limit the contract values you are considered for. You cannot directly control your D&B score, but you can ensure the underlying data is accurate and current.

Common issue: Directors of relatively new limited companies sometimes find their D&B rating is lower than expected simply because there is insufficient financial history. If this applies to you, consider whether filing abbreviated accounts (where still permitted under the Companies Act 2006, s.444) is limiting the data available to D&B — more detailed filings can sometimes produce a better picture.

3. Environmental Management

Gold requires evidence of genuine environmental management, proportionate to your scale. You do not need ISO 14001 certification. You do need:

• A written environmental policy signed by a director, covering your actual operations
• Identification of your significant environmental impacts (waste, dust, noise, water pollution, energy use — whatever applies to your trade)
• Waste management procedures, including evidence of compliance with the duty of care for waste transfer (Environmental Protection Act 1990, s.34)
• Evidence of workforce environmental awareness (briefings, toolbox talks)
• Where applicable, evidence of compliance with relevant environmental permits or exemptions

A 20-person demolition contractor will have very different environmental impacts from a 10-person electrical contractor. The assessor is looking for evidence that you have identified your specific impacts and manage them, not that you have adopted a one-size-fits-all template.

4. Quality Management

Gold requires documented quality management procedures. Again, ISO 9001 certification is not mandatory for SMEs, but you need to demonstrate a systematic approach to quality, including:

• A quality policy or statement
• Procedures for inspection and testing of your work
• A process for managing defects and non-conformances
• Customer feedback and complaints handling
• Documented responsibilities for quality oversight

For a small subcontractor, this might mean a clear quality procedure document covering how you inspect completed work, how you handle snag lists, who signs off quality checkpoints, and how customer complaints are recorded and resolved. Assessors are looking for evidence of a working system, not a shelf of paperwork.

5. Equal Opportunities and Diversity

A written equal opportunities policy demonstrating commitment to fair treatment across all protected characteristics under the Equality Act 2010. The policy should cover recruitment, employment, training, and promotion. Assessors look for:

• A policy signed by a director
• Evidence that recruitment decisions are based on competence
• A grievance or complaints procedure for discrimination issues
• Awareness among managers and supervisors

For SMEs, this does not need to be elaborate. It needs to be genuine and operational. If you employ subcontractors or agency workers, the policy should address how you extend fair treatment expectations through your supply chain.

6. Anti-Bribery and Corruption

Under the Bribery Act 2010, all UK businesses — regardless of size — can be held liable for failing to prevent bribery. Constructionline Gold requires evidence that you have addressed this, typically through:

• A written anti-bribery and corruption policy
• Awareness among staff (particularly those involved in tendering and procurement)
• Proportionate procedures to prevent bribery — for SMEs, this might include a gifts and hospitality register, due diligence on subcontractors and suppliers, and a clear reporting mechanism

The Ministry of Justice guidance on the Bribery Act 2010 (published 2011) explicitly acknowledges that procedures should be proportionate to the size and nature of the business. A 15-person roofing firm does not need the same compliance infrastructure as a multinational. But you do need to demonstrate that you have considered the risk and put basic measures in place.

The Application Process: Step by Step

Step 1: Audit Your Current Position

Before paying any fees, map your existing documentation against the six assessment areas above. Use our Health & Safety Documentation Checklist for the H&S component and our Construction Accreditation Readiness Scorer for a broader assessment of your position.

The gap between Silver and Gold catches many applicants. You may have robust health and safety documentation but nothing in place for environmental management, quality, or anti-bribery. Identify these gaps early.

Step 2: Prepare Your Documentation

Address every gap. Write the policies, establish the procedures, and gather the evidence. This is the most time-consuming part of the process — budget at least two to four weeks for a thorough preparation if you are starting from scratch on the Gold-level areas.

Key preparation tasks:

• Draft or update environmental, quality, equal opportunities, and anti-bribery policies
• Ensure your health and safety documentation is current and complete
• Verify your insurance certificates are valid and cover levels are adequate (use our Construction Insurance Requirements Calculator)
• Check your Companies House filings are up to date
• Compile training records into a single, accessible format

Step 3: Register on the Constructionline Portal

Create an account on the Constructionline website. You will need your company registration number, SIC codes, details of your work categories, and contact information for the person managing the application.

Step 4: Select Gold Tier

When prompted, select Gold as your membership tier. The system will present the full set of questions and documentation requirements for Gold-level assessment.

Step 5: Complete the Online Application

Work through each section of the application. Answer questions specifically and honestly — vague responses trigger assessor queries. Upload supporting documentation with clear, descriptive file names.

Step 6: Pay the Membership Fee

Constructionline membership fees vary by company turnover. Gold membership fees for SMEs are typically in the range of several hundred pounds per year, varying by company turnover. Fees are reviewed regularly — last verified February 2026. Always check the current fee schedule on the Constructionline website before applying.

Step 7: Assessment and Verification

Constructionline will assess your application, verify your uploaded documentation, and conduct financial checks through Dun & Bradstreet. If the assessor needs clarification or additional evidence, you will receive a notification through the portal. Respond promptly and thoroughly.

Step 8: Approval and Listing

Once approved, your business is listed on the Constructionline register at Gold level, visible to all registered buyers. Your profile will display your verified work categories, financial rating, accreditation status, and geographic coverage.

Common Failure Points at Gold Level

The health and safety component at Gold level is the same as Silver, and the common failures are the same — generic policies, expired documents, incomplete risk assessments. For a detailed breakdown, see our accreditation requirements guide.

The additional Gold-level areas have their own common failure points:

Environmental Policy Without Substance

A one-page environmental policy that reads like a mission statement but includes no specific impacts, no waste management procedures, and no evidence of implementation. Assessors want to see that your environmental management relates to your actual operations.

No Quality Procedures

Many SMEs have informal quality processes — the site supervisor checks the work, the director handles complaints — but nothing documented. At Gold level, you need documented procedures, even if they are simple. The system needs to exist on paper, not just in the director's head.

Missing Anti-Bribery Policy

Anti-bribery is the area most commonly overlooked by SMEs applying for Gold. Many businesses have never considered it relevant to their scale. It is a legal requirement under the Bribery Act 2010, and Gold assessment specifically checks for it. Write the policy. It does not need to be long — but it needs to exist and demonstrate proportionate measures.

Inconsistencies Between Documents

If your health and safety policy says you employ 25 people, your equal opportunities policy says 30, and your application says 20, the assessor will flag it. Ensure consistency across all documents before submission.

How Long Does Constructionline Gold Last?

Constructionline membership is renewed annually. At renewal, your documentation is reassessed and your financial data is refreshed through Dun & Bradstreet. Maintaining your documentation throughout the year — rather than treating renewal as an annual scramble — makes the process significantly smoother.

Why Tier 1 Contractors Increasingly Specify Gold

The shift from Silver to Gold as a baseline requirement reflects broader trends in construction procurement. The Construction (Design and Management) Regulations 2015 (CDM 2015) place duties on clients and principal contractors to assess the competence and resources of their supply chain (see our CDM 2015 duties guide). Beyond health and safety, public-sector procurement frameworks aligned to PAS 91 increasingly require evidence across environmental, quality, and equality dimensions.

For Tier 1 contractors, requiring Gold simplifies their own compliance obligations. Rather than running separate checks across multiple areas, they can rely on Constructionline's assessment. For you as an SME subcontractor, meeting Gold requirements is not just about passing an assessment — it signals that your business operates to the standard that Tier 1 buyers expect.

For SME contractors, CDM 2015 can feel like a regulatory maze. This guide cuts through the complexity and explains what the regulations actually require of you, how the duty holder roles work, and where CDM obligations intersect with accreditation requirements.

TenderReady is not affiliated with the Health and Safety Executive or any accreditation body. This is not legal advice — for specific situations, consult a competent health and safety professional or legal adviser.

What Are the CDM 2015 Regulations?

CDM 2015 replaced CDM 2007 and came into force on 6 April 2015. The regulations apply to all construction work in England, Scotland, and Wales, and are enforced by the Health and Safety Executive (HSE).

CDM 2015 applies to all construction work — new build, demolition, alteration, fitting out, refurbishment, maintenance, and repair. There is no minimum project value or duration threshold, although duties vary depending on whether the project is notifiable and whether it involves more than one contractor.

A project is notifiable to the HSE if the construction work is expected to last longer than 30 working days with more than 20 workers simultaneously at any point, or exceed 500 person days.

The Five Duty Holder Roles

CDM 2015 defines five duty holder roles. Understanding these roles and knowing which ones apply to you is essential.

1. Client

The client is the person or organisation for whom the construction work is carried out. Under CDM 2015, the client has active duties: making suitable arrangements for managing the project, appointing a principal designer and principal contractor (where required), providing relevant site information, and ensuring a construction phase plan and welfare facilities are in place.

For domestic clients, these duties transfer automatically to the contractor or principal contractor.

2. Principal Designer

The principal designer is appointed by the client on projects involving more than one contractor. Their role is to coordinate the pre-construction phase, with particular focus on identifying, eliminating, and controlling foreseeable risks.

As an SME contractor, you are unlikely to hold this role unless you also carry out design work. However, design information relevant to construction risks should flow through to you before you start work.

3. Principal Contractor

The principal contractor is appointed by the client on projects involving more than one contractor. Their duties include planning and coordinating the construction phase, preparing the construction phase plan, organising cooperation between contractors, ensuring site inductions, maintaining welfare facilities, and consulting with workers.

If you are the main contractor on a project with subcontractors, you may well be the principal contractor — bringing substantial coordination duties beyond managing your own workforce.

4. Designer

A designer is anyone who prepares or modifies a design relating to construction work — including contractors who design temporary works, formwork, or elements of the permanent works. If your company designs anything, you have duties under CDM 2015 to eliminate foreseeable risks where possible.

5. Contractor

Every contractor on a construction project has duties under CDM 2015 — this role will always apply to you. Key duties include planning and monitoring your own work, ensuring welfare facilities are in place before starting, verifying worker competence, complying with the construction phase plan, and cooperating with other contractors.

On projects with only a single contractor (no subcontractors), that contractor assumes both the contractor duties and the principal contractor duties.

What CDM 2015 Means for SME Contractors in Practice

Understanding the duty holder roles is only useful if you can translate them into practical action. Here is what CDM 2015 requires of you in your day-to-day operations.

Construction Phase Plan

The construction phase plan sets out the arrangements for managing health and safety during the construction phase. The principal contractor is responsible for preparing it; on single-contractor projects, the contractor must prepare it.

The plan does not need to be lengthy. For smaller projects, a concise plan covering key risks, site rules, emergency procedures, and management arrangements is adequate. What matters is that the plan is specific to the project and is in place before construction work begins. A generic plan that is not tailored to the specific site will not satisfy the regulations.

Competence and Skills

CDM 2015 requires that workers are competent for the tasks they carry out. For SME contractors, this means maintaining up-to-date training records, ensuring relevant CSCS cards and management qualifications (SMSTS, SSSTS, or equivalent) are held and current, verifying the competence of subcontractors you engage, and providing adequate supervision for less experienced workers.

Competence is not just about holding cards and certificates. It encompasses knowledge, experience, and the ability to identify and manage risk in practice. Assessors will look beyond certificates to evidence of how competence is maintained and applied.

Welfare Facilities

Contractors must not start work unless satisfied that adequate welfare facilities are available — toilets, washing facilities, drinking water, changing facilities, rest areas, and facilities for heating food. These are non-negotiable legal requirements.

Cooperation and Coordination

CDM 2015 emphasises cooperation between all parties. You must cooperate with the principal contractor, follow the construction phase plan, attend site inductions, and share information about risks from your work that could affect others.

How CDM 2015 Relates to Accreditation Requirements

CDM 2015 and accreditation are closely linked. Accreditation schemes aligned to the SSIP core criteria assess whether your health and safety management is robust — and those arrangements must address your CDM duties.

Assessors will look for evidence that you understand your duty holder roles, that your health and safety policy addresses CDM requirements (construction phase planning, competence, welfare, cooperation), that you have processes for producing project-specific construction phase plans, and that your training records support your ability to fulfil CDM roles.

A construction SME that can demonstrate practical readiness for CDM duties is well-positioned to achieve and maintain accreditation. Gaps in CDM understanding are frequently flagged during assessments.

For a broader overview of what accreditation schemes require, see our guide: Construction Accreditation Requirements.

Common Misconceptions About CDM 2015

"CDM only applies to large projects." Incorrect. CDM 2015 applies to all construction work. The appointment requirements vary based on contractor numbers, but every project has CDM duties.

"The client is responsible for everything." The client has important duties, but CDM 2015 distributes responsibilities across all duty holders. As a contractor, you have duties regardless of what the client does.

"A construction phase plan is only needed for notifiable projects." A construction phase plan is required for every project with more than one contractor, whether notifiable or not. For single-contractor projects, planning and managing the work safely is still required — and expected by accreditation schemes.

"We are too small for CDM to apply." Size does not determine applicability. A sole trader has CDM duties. The regulations are scalable, but they always apply.

"Holding CSCS cards equals CDM competence." CSCS cards are one element, but CDM competence is broader — it includes the organisational systems, procedures, and oversight needed to manage construction work safely.

Summary

CDM 2015 is not optional, and it applies to every construction SME. The practical steps are clear: understand which duty holder roles apply to your business, ensure your health and safety policy addresses CDM responsibilities, maintain competence records, produce project-specific construction phase plans, and cooperate actively with other parties on every project.

Getting CDM right is about running safe, well-managed projects — which is what wins repeat work and sustains a construction business over the long term.

This guide explains PAS 91 in practical terms: what it covers, who uses it, what documentation you will need, and how to prepare efficiently.

Disclaimer: This guidance is based on publicly available information about PAS 91 and established industry practice. TenderReady is not affiliated with BSI, any accreditation body, or any public sector procurement organisation. Requirements may vary between procurers — always check the specific PQQ you are responding to.

What Is PAS 91?

PAS 91 is a Publicly Available Specification published by BSI (British Standards Institution). Its full title is PAS 91: Construction prequalification questionnaires. It provides a standardised framework for PQQs used in the construction industry.

Before PAS 91, every procurer used their own bespoke PQQ format. Contractors were completing dozens of different questionnaires each year, often providing the same information in different formats. PAS 91 addresses this by defining a common set of modules and questions.

PAS 91 is not a law or regulation — it is a specification that procurers choose to adopt. However, UK Government procurement guidance strongly encourages public sector bodies to use PAS 91-aligned prequalification, and in practice it has become the de facto standard for public sector construction procurement.

Who Uses PAS 91?

You are most likely to encounter PAS 91 in the following contexts:

• Public sector procurement — Local authorities, central government departments, NHS trusts, and housing associations commonly use PAS 91-aligned PQQs for construction and maintenance contracts.
• Tier 1 and Tier 2 contractors — Many principal contractors have adopted PAS 91 as the basis for their supply chain prequalification, particularly for subcontractors working on publicly funded projects.
• Framework agreements — Construction frameworks (such as those procured through CCS, PAGABO, or regional frameworks) typically use PAS 91-aligned prequalification at the supplier admission stage.
• Third-party prequalification services — Schemes such as Constructionline use PAS 91 as the foundation for their assessment, meaning that if you hold Constructionline accreditation, much of the PAS 91 ground is already covered.

Core Modules in PAS 91

PAS 91 is structured around a set of modules covering different aspects of a contractor's competence and standing. The typical core modules include:

• Company Information — Legal entity, registration details, VAT, key contacts, and scope of activities.
• Financial Standing — Recent accounts, relevant turnover, and any significant financial events (insolvency, CCJs, or similar).
• Health and Safety — Policy, risk assessment processes, training and competence, accident records, and enforcement history. This is where SSIP recognition is directly relevant — holding accreditation through an SSIP member scheme can satisfy this section in whole or in part.
• Insurance — Employers' liability (mandatory minimum £5 million, though many contracts require £10 million), public liability, and professional indemnity where applicable.
• Equality and Diversity — Arrangements for meeting the Equality Act 2010.
• Environmental Management — Environmental policy and processes, which may include alignment to ISO 14001.
• Quality Management — ISO 9001 certification or equivalent documented procedures.
• Building Information Modelling (BIM) — Capability and experience where BIM is required.

Not every PQQ includes all modules. Procurers select those relevant to the contract. For simpler subcontract packages, you may only need to complete company information, financial standing, health and safety, and insurance.

How PAS 91 Relates to SSIP Schemes

There is significant overlap between PAS 91 requirements and SSIP accreditation, particularly in the health and safety module. If you hold current accreditation through an SSIP member scheme — whether CHAS, SafeContractor, Constructionline, SMAS, Acclaim, or another member — you have already demonstrated compliance with the SSIP core criteria, which covers many of the health and safety questions in a PAS 91 PQQ.

In practice:

• Constructionline is the most closely aligned with PAS 91, as its assessment is explicitly built on the PAS 91 framework. Holding Constructionline Gold effectively covers the health and safety, financial, and several supplementary modules.
• CHAS, SafeContractor, and other SSIP schemes cover the health and safety module but not necessarily the financial, environmental, or quality modules.
• Many procurers accept SSIP accreditation as evidence for the health and safety section, reducing the amount of additional information you need to provide. However, this is at the procurer's discretion — some will still ask for supplementary evidence.

The key point is that PAS 91 is broader than health and safety alone. Even with SSIP accreditation, you will likely need to provide additional documentation covering financial standing, insurance, environmental management, and other areas.

What Documentation Do PAS 91 Assessors Typically Expect?

While exact requirements depend on the procurer and the modules selected, you should be prepared to provide:

• Health and safety policy — Current, signed, and specific to your business
• Risk assessments — Examples relevant to the type of work being tendered
• Method statements — Demonstrating your approach to managing high-risk activities
• Training records and competence certificates — CSCS cards, SMSTS/SSSTS, trade qualifications, plant operator certificates
• Accident and incident records — Including RIDDOR reports and your accident frequency rate
• Insurance certificates — Current and showing adequate cover levels
• Audited accounts or management accounts — Typically the most recent two to three years
• Environmental policy — And evidence of how you manage environmental risks in practice
• Quality procedures — Whether certified to ISO 9001 or documented internal processes
• Equality and diversity policy — Current and reflecting your legal obligations
• References — Contact details for recent clients who can confirm satisfactory performance
• Enforcement action history — Details of any HSE enforcement notices, prosecutions, or improvement notices

Practical Preparation Tips

Maintain a Prequalification File

Maintain a standing prequalification file with all your standard documentation. Update it quarterly and after any significant business change — current policies, certificates, accounts, and standard PQQ responses should all be readily accessible.

Align Your Documentation Early

If your health and safety policy already meets SSIP core criteria, it should be well-suited to the PAS 91 health and safety module. However, review it specifically against PAS 91 expectations. Ensure your policy references current legislation, names responsible persons, and includes arrangements for all activities relevant to your typical contracts.

Know Your Numbers

Financial questions catch out many SMEs. Know your turnover for the last three years, your largest single contract value, your current order book, and your credit score. Have your accounts available in the format the PQQ requests — do not assume management accounts will always be accepted where audited accounts are requested.

Be Honest About Enforcement History

PAS 91 PQQs ask about HSE enforcement action, prosecutions, and convictions. Dishonesty will result in disqualification. If you have enforcement history, be upfront — explain what happened and what you changed. Procurers are more understanding of a well-managed response than an attempt to conceal.

Use Your Accreditation Strategically

Where a PQQ asks for health and safety evidence and you hold SSIP accreditation, reference it prominently. Provide your certificate number and confirm which scheme you hold. Many PQQs have a specific field for SSIP registration, which can significantly reduce the supporting documentation required.

For more on how prequalification works across the UK construction sector, see our detailed guide: Construction Supplier Prequalification in the UK.

Summary

PAS 91 is the standard framework for construction prequalification in the UK. Understanding its structure and preparing your documentation in advance will save you significant time and improve your success rate when tendering. If you already hold SSIP accreditation, you have a strong foundation — but PAS 91 extends beyond health and safety, so ensure your financial, environmental, quality, and equality documentation is equally well-prepared.

The contractors who win work consistently are not necessarily those with the most impressive credentials. They are the ones who respond to PQQs quickly, accurately, and completely — because they have their documentation organised and ready before the opportunity arrives.

This guide explains the legal requirements, breaks down what assessors are actually looking for, identifies the most common mistakes that cause rejections, and gives you practical guidance for writing a policy that reflects your business and your work.

Disclaimer: This article provides guidance based on publicly available information and established industry practice. TenderReady is not affiliated with CHAS, Constructionline, SafeContractor, or any other accreditation body. Requirements may vary between schemes and over time — always check directly with the relevant body.

The Legal Requirement: Health and Safety at Work Act 1974

Under the Health and Safety at Work etc. Act 1974, every employer with five or more employees is legally required to have a written health and safety policy. This is a statutory obligation, not a best-practice recommendation.

Even if you have fewer than five employees, accreditation schemes will still expect a written policy. The Act places a general duty on all employers to ensure, so far as is reasonably practicable, the health, safety, and welfare of their employees and anyone else affected by their undertaking. The Management of Health and Safety at Work Regulations 1999 further require risk assessments and arrangements for planning, organisation, control, monitoring, and review of preventive measures. Your policy should reference and support these requirements.

The Three Parts of a Health and Safety Policy

A properly structured health and safety policy has three distinct sections. Assessors will check that all three are present and properly developed.

Part 1: Statement of Intent

This is the senior leadership commitment to health and safety. It should:

• Be signed and dated by the most senior person in the business (owner, managing director, or equivalent)
• State the company's commitment to providing a safe and healthy working environment
• Reference the Health and Safety at Work etc. Act 1974 and other relevant legislation
• Commit to providing adequate resources, training, and competent advice
• Set out the intention to review the policy at regular intervals

The statement of intent should be concise — typically one page. It should not be a generic pledge copied from a template. Assessors want to see that the person who signed it understands what they are committing to.

Common mistake: Using a statement of intent that names legislation incorrectly, omits a signature, or has no date. A surprising number of applications are returned simply because the statement is unsigned or carries a date from several years ago.

Part 2: Organisation

This section sets out who is responsible for what. It is the organisational structure for health and safety within your business. It should clearly identify:

• The person with overall responsibility for health and safety (usually the managing director or owner)
• Managers and supervisors with specific responsibilities
• The competent person or persons providing health and safety advice (whether in-house or an external consultant, as required by Regulation 7 of the Management Regulations 1999)
• Employee responsibilities — everyone has a duty to cooperate, report hazards, and use equipment correctly
• Any specialist roles (first aiders, fire marshals, asbestos duty holders, temporary works coordinators)

For SMEs, this section does not need to be lengthy. What matters is that named individuals are assigned to specific responsibilities, and that the structure is realistic and reflects how your business actually operates.

Common mistake: Listing responsibilities but not assigning them to named people. Assessors will reject a policy that says "a manager will be responsible for..." without identifying who that manager is. Similarly, listing people who have left the business is a clear sign the policy has not been reviewed.

Part 3: Arrangements

This is the longest and most detailed section. It describes how you manage health and safety in practice — the systems, procedures, and processes that turn your statement of intent into reality. It should cover every significant aspect of your work. Typical topics include:

• Risk assessment, method statements, and safe systems of work
• Training, competence, and supervision arrangements
• PPE selection, provision, and enforcement
• Working at height, manual handling, and COSHH
• Asbestos awareness and procedures
• Fire safety, electrical safety, and plant/equipment management
• Noise and vibration assessment
• Accident and incident reporting (including RIDDOR)
• Employee consultation on health and safety matters
• Monitoring, review, and emergency procedures
• Welfare provision on site

The arrangements section must be specific to your activities. A groundworks contractor will have different risk priorities from a mechanical and electrical subcontractor. Assessors look for evidence that you have thought about your own work, not simply listed every possible topic.

Common mistake: Copying a generic template that includes arrangements for hazards you never encounter while omitting those central to your work. If you are a roofing contractor with no section on working at height, that is a serious red flag.

What Accreditation Assessors Look For

Across SSIP member schemes such as CHAS, SafeContractor, and Constructionline, assessors check against the SSIP core criteria. Key areas of focus include:

Specificity. Does the policy reflect this business and its activities, or is it generic boilerplate?

Named responsibilities. Are real people identified against specific roles? Is the competent person named?

Currency. Has the policy been reviewed within the last 12 months? Is the review date stated?

Legislative awareness. Does the policy reference correct, current legislation? Outdated references (for example, citing superseded regulations rather than CDM 2015) suggest poor maintenance.

Integration. Does the policy connect to risk assessments, method statements, and training records? A policy that exists in isolation looks like a paper exercise.

Proportionality. Is the policy proportionate to business size? An SME with 12 employees does not need a 100-page document.

Common Mistakes That Cause Rejection

Based on common feedback from assessors and industry peers, the most frequent causes of rejection are:

1. No named individuals in the organisation section. Responsibilities assigned to job titles only, with no names.
2. No review date or an expired review date. If the last review was 18 months ago, that is a problem.
3. Generic content that does not match the business. A shopfitting company with a section on excavation work but nothing on dust or working at height.
4. Missing statement of intent signature. An unsigned policy does not meet the legal requirement.
5. No reference to competent advice. Regulation 7 requires access to competent health and safety advice — if your policy does not identify who provides this, assessors will query it.
6. Outdated legislation references. Citing repealed or superseded regulations suggests the policy has not been reviewed.
7. No arrangements for core activities. Omitting the hazards most relevant to your day-to-day work.
8. Copy-pasted content. Assessors recognise recycled text, and it risks including information that does not apply to your business.

Practical Tips for Writing a Policy That Passes

Start from your actual work. List the activities you carry out, the main hazards your workers face, and the controls already in place. Your policy should document reality, not describe an ideal world.

Use your own words. Plain, clear language that your site managers would actually read is far more credible to an assessor than corporate legalese.

Name people, not just roles. "Joe Smith, Site Manager, is responsible for..." is always better than "The site manager is responsible for..."

Set a realistic review schedule. Annually is the standard expectation. Put the date in the policy and a reminder in your calendar.

Keep arrangements proportionate. Cover everything relevant to your work, but do not pad the policy with irrelevant topics. Quality over quantity.

Cross-reference supporting documents. Where your policy mentions risk assessments or training records, reference where these are held and who maintains them.

Keeping Your Policy Current

A health and safety policy is a living document. Keep it current by:

• Reviewing annually at minimum, updating the review date each time
• Updating after significant changes — new activities, new sites, changes in personnel, or incidents that reveal gaps
• Re-signing after major revisions — the statement of intent should carry a current signature
• Communicating changes — brief your teams on any material updates

Use our free H&S Documentation Checklist to review whether your policy and supporting documents are ready for assessment.

Summary

Your health and safety policy is the foundation of your accreditation application. It must meet the legal requirements, be specific to your business and activities, properly signed and dated, and regularly reviewed. The most common reasons for rejection are avoidable — generic content, missing signatures, unnamed responsibilities, and outdated information.

Take the time to get this document right. It will not only improve your chances of passing accreditation first time, but it will also give your business a genuinely useful tool for managing health and safety on every project you deliver.

If you run a construction SME in the UK, you will have encountered requests for health and safety accreditation — often as a non-negotiable requirement on tender prequalification questionnaires. The acronym SSIP appears frequently, but many contractors are unclear on what it actually means, how it differs from the individual schemes, and which scheme represents the best fit for their business.

This guide breaks down SSIP, explains how mutual recognition works in practice, and helps you decide which member scheme to pursue. For a broader overview of how prequalification works in UK construction, see our Complete Guide to Construction Supplier Prequalification.

Disclaimer: The guidance in this article is based on publicly available information and widely recognised industry norms. TenderReady is not affiliated with, endorsed by, or formally connected to SSIP or any of its member schemes. Always verify specific requirements directly with the relevant accreditation body.

What Does SSIP Stand For?

SSIP stands for Safety Schemes in Procurement. It is not itself an accreditation scheme — rather, it is a forum and umbrella body that brings together multiple health and safety assessment schemes under a common framework. SSIP was established to reduce duplication and cost for contractors who previously had to achieve separate accreditations for every client or sector they worked in.

The core idea is simple: if a contractor achieves accreditation through one SSIP member scheme, that achievement should be recognised by other member schemes through a process called mutual recognition. This avoids the need for businesses to undergo multiple full assessments covering substantially the same ground.

SSIP's role is to set a core criteria standard that all member schemes must assess against. This core criteria is aligned to relevant UK health and safety legislation and is reviewed periodically. Each member scheme may add its own supplementary requirements on top of the SSIP core criteria, but the baseline is consistent.

How Does SSIP Mutual Recognition Work?

Mutual recognition is the mechanism by which SSIP member schemes accept assessments carried out by other member schemes. In practical terms:

1. You achieve accreditation through one SSIP member scheme (for example, CHAS).
2. A client or principal contractor requires evidence of accreditation through a different SSIP member scheme (for example, SafeContractor).
3. Rather than completing a full new assessment, your existing accreditation is recognised — subject to any additional requirements specific to the second scheme.

There are important caveats. Mutual recognition covers the SSIP core criteria only. If the second scheme has supplementary modules or sector-specific requirements, you may still need to complete additional assessments. In practice, the process is not always seamless, and some schemes handle transfers more smoothly than others.

For SMEs, mutual recognition significantly reduces the administrative burden and cost of maintaining multiple accreditations. However, it is worth understanding that some clients specify a particular named scheme in their prequalification requirements, in which case mutual recognition may not fully satisfy their procurement criteria.

SSIP Member Schemes: Who Are They?

SSIP has a number of member schemes. The most commonly encountered in UK construction include:

• CHAS (Contractors Health and Safety Assessment Scheme) — One of the longest-established schemes, widely recognised across public and private sector procurement. Offers tiered levels including CHAS Standard, Advanced, and Elite.
• SafeContractor — Popular across facilities management, construction, and maintenance sectors. Known for a relatively streamlined assessment process.
• Constructionline — Operated by Capita and closely integrated with public sector procurement. Offers Gold and Silver tiers that bundle financial, health and safety, and capability assessments.
• SMAS (Safety Management Advisory Services) — Particularly strong in Scotland and the north of England. Offers Worksafe and additional modules.
• Acclaim Accreditation — Operated by the Building Research Establishment (BRE). Well-regarded in construction and property sectors.
• Avetta — A global supply chain risk management platform with SSIP membership for its UK assessments.
• NESMA (North East Safety Management Association) — Regional scheme with a strong presence in the north-east of England.

This is not an exhaustive list. SSIP publishes a current list of member schemes on its website, which is worth checking as membership does change over time.

For a detailed comparison of the three schemes most commonly required in construction tenders, see our guide: CHAS vs Constructionline vs SafeContractor.

How to Decide Which SSIP Scheme to Choose

Choosing the right scheme is not simply about finding the cheapest option. Several factors should inform your decision:

1. What Do Your Clients Require?

Start with your current and target clients. Review the prequalification questionnaires and tender documentation for your most important contracts. If a specific scheme is repeatedly named, that scheme should be your priority. Some principal contractors and public sector bodies have preferred suppliers lists tied to particular schemes.

2. Sector Alignment

While all SSIP schemes cover the same core criteria, some have stronger recognition in particular sectors:

• Public sector and local authority work — Constructionline and CHAS are very widely recognised.
• Facilities management and maintenance — SafeContractor has a strong presence.
• Housebuilding and residential — CHAS and Acclaim are commonly specified.
• Scotland and regional work — SMAS has particularly strong recognition.

3. What Else Do You Get?

Some schemes offer more than a health and safety assessment:

• Constructionline bundles financial standing checks, anti-bribery, modern slavery, equality, and environmental assessments into its Gold tier.
• CHAS offers a supply chain verification service and common assessment standard across its tiers.
• SafeContractor provides a contractor management portal and buyer network.

If you need to demonstrate competence across multiple areas — not just health and safety — a scheme with broader scope may offer better value.

4. Cost Considerations

Pricing varies between schemes and typically depends on your company's turnover and employee count. As a general guide for small to medium contractors:

• Annual fees typically range from a few hundred to over a thousand pounds depending on the scheme, tier, and company size.
• Some schemes charge additional fees for supplementary modules (environmental management, quality management, modern slavery).
• Multi-year subscriptions sometimes attract a discount.

Always obtain a direct quote from the scheme before committing. Prices are reviewed regularly and may differ from figures published online.

5. Assessment Process

The assessment process varies in format and rigour:

• Some schemes are fully desktop-based, relying on uploaded documentation.
• Others include telephone or video interviews with a qualified assessor.
• Turnaround times can range from a few days to several weeks depending on the scheme and time of year (there is typically a rush before financial year-end in March).

If speed matters — for example, you need accreditation to meet a tender deadline — ask each scheme about current processing times before applying.

Benefits of SSIP Recognition for Construction SMEs

Achieving accreditation through an SSIP member scheme delivers several practical benefits:

Tender access. Many public and private sector contracts require SSIP-recognised accreditation as a minimum threshold. Without it, you will not pass prequalification.

Reduced duplication. Mutual recognition means one assessment can satisfy multiple client requirements, saving time and money.

Improved health and safety management. The assessment process itself is valuable. It forces you to review your policies, risk assessments, training records, and method statements — and to address gaps that may have developed over time.

Client confidence. Holding current SSIP accreditation signals to clients and principal contractors that your health and safety management has been independently assessed against a recognised standard.

Competitive advantage. For SMEs competing against larger firms, accreditation helps level the playing field. It provides third-party evidence of competence that does not rely solely on your track record or turnover.

Preparing for Your SSIP Assessment

Regardless of which scheme you choose, the core documentation requirements are broadly similar. You will typically need:

• A written health and safety policy (with statement of intent, organisation, and arrangements sections)
• Risk assessments relevant to your activities
• Method statements or safe systems of work
• Evidence of competent health and safety advice (whether in-house or external)
• Training records and qualification certificates
• Employers' liability insurance certificate
• Accident and incident reporting procedures
• Evidence of monitoring and review processes

The quality and specificity of this documentation is what separates a clean pass from a request for further information. Generic, off-the-shelf templates that do not reflect your actual activities are the most common cause of delays and resubmissions.

Summary

SSIP is not a scheme — it is the framework that connects multiple health and safety assessment schemes under a common standard. Mutual recognition reduces duplication, but choosing the right scheme still matters. Start with what your clients require, consider the scope and cost of each option, and invest time in getting your documentation right before you apply.

The accreditation itself is not the end goal. It is a structured way to ensure your health and safety management is robust, current, and fit for the work you are doing. For construction SMEs, that is both a commercial necessity and a genuine safeguard for your workforce.

Understanding what is commonly checked, what "good" looks like at SME scale, and where businesses most often fall short gives you a significant advantage. This guide covers the eight core documentation areas that form the backbone of most construction prequalification assessments.

1. Health and Safety Policy

Assessors expect a policy that is signed by a director, dated and reviewed within the last 12 months, specific to your business activities (not a generic template), and structured in three parts: a general statement of intent, the organisation of responsibilities naming individuals, and practical arrangements for implementation.

What good looks like: For a 15-person groundworks contractor, the policy references the specific hazards of groundworks (excavation, underground services, working near traffic), names the site supervisor responsible for day-to-day safety, and describes the practical arrangements — toolbox talks, site inductions, PPE provision, incident reporting — that the business actually uses.

Common gaps: Generic policies purchased online. Policies referencing activities the business does not carry out (or omitting activities it does). Policies signed by someone who has left the business or last reviewed more than 12 months ago.

2. Risk Assessments

Activity-specific risk assessments covering the significant hazards associated with your operations. Assessors look for evidence that you have systematically identified what could cause harm, who might be harmed, and what control measures are in place, following the HSE five-step process.

What good looks like: A roofing contractor with 10 employees should have assessments for working at height, manual handling, power tools, adverse weather, and asbestos exposure. Each should identify specific controls — not just "wear PPE" but "operatives to use Class 3 edge protection on all roof perimeters above 2 metres." Evidence of regular review is essential.

Common gaps: Assessments covering "construction work" generically rather than specific activities. Hazards identified but with vague controls. No evidence of review or update. Missing assessments for higher-risk operations like confined space entry.

3. Method Statements and RAMS

RAMS describe how specific tasks will be carried out safely, translating risk assessment controls into a practical, step-by-step sequence of work. For high-risk activities, these are essential for both prequalification and site-level compliance.

What good looks like: Template RAMS for your core activities, adapted for each project. A scaffolding erection method statement covering scope, sequence, competence requirements, PPE, equipment inspection, exclusion zones, and emergency arrangements. Assessors accept that SMEs use templates — but they look for evidence of project-specific adaptation and workforce communication (briefing sign-off sheets).

Common gaps: Method statements that duplicate risk assessments rather than providing operational instructions. RAMS never adapted for specific sites. No evidence of communication to operatives.

4. Insurance

Current certificates for employers' liability (minimum £5 million legally, though most Tier 1 contractors require £10 million), public liability (typically £5-10 million), and professional indemnity where you provide design or advisory services.

What good looks like: Current certificates with adequate cover, continuous with no gaps between policy periods, and cover levels that meet or exceed client-specific requirements.

Use our Construction Insurance Requirements Calculator to check whether your cover aligns to common client requirements.

Common gaps: Expired certificates (the most common and most avoidable issue). Cover levels below client minimums. Missing professional indemnity where the business provides design input, even incidentally.

5. Training Records

Assessors look for CSCS cards for all operatives, SMSTS for site managers, SSSTS for supervisors, trade-specific qualifications (IPAF, PASMA, CPCS, JIB, Gas Safe), health and safety awareness training (asbestos awareness, manual handling, working at height), and adequate first aid provision.

What good looks like: A training matrix — even a well-maintained spreadsheet — showing every employee, their required competences, qualifications held, and expiry dates. Evidence of ongoing training beyond formal qualifications: toolbox talk records, CPD attendance, and safety briefing sign-off sheets.

Common gaps: No centralised training record. Expired CSCS cards. Missing supervisory qualifications. No evidence of ongoing training or toolbox talks. Trade-specific gaps such as operatives using powered access without valid IPAF certification.

6. Environmental Policy

A written environmental policy appropriate to your scale. This does not need ISO 14001 certification for SMEs, but assessors look for a director-signed policy statement, identification of your environmental impacts (waste, noise, dust, water pollution, energy), practical measures to minimise those impacts, waste management procedures including duty of care for waste transfer, and evidence of workforce environmental awareness.

What good looks like: A clear policy acknowledging the specific environmental impacts of your operations. A demolition contractor would cover dust suppression, noise management, waste segregation, and contaminated materials. An electrical contractor would focus on waste cable, packaging, and energy use.

Common gaps: No environmental policy at all (still common among smaller contractors). Generic policies that do not reference actual impacts. No waste management procedures or waste transfer notes.

7. Equal Opportunities Policy

A written policy demonstrating commitment to fair treatment in employment and recruitment, covering all protected characteristics under the Equality Act 2010. Assessors look for evidence of fair recruitment practices, a grievance procedure for discrimination complaints, and manager awareness.

What good looks like: A clear, concise policy reflecting your business. You do not need a dedicated diversity team — but you do need a clear commitment, evidence that recruitment decisions are based on competence, and a process for handling complaints. If you employ subcontractors or agency workers, the policy should extend through your supply chain.

Common gaps: No written policy. A policy listing protected characteristics without practical implementation arrangements. No complaints procedure linked to the policy.

8. Modern Slavery Statement

Although the Modern Slavery Act 2015 only mandates statements for businesses with turnover above £36 million, accreditation bodies and Tier 1 contractors increasingly expect all supply chain partners to demonstrate awareness and due diligence.

What good looks like: A proportionate statement acknowledging modern slavery risks in construction, describing practical steps — verifying right-to-work documentation, using only licensed gangmasters where applicable, checking subcontractor employment practices — and naming the person responsible for oversight.

Common gaps: No statement at all (many SMEs assume it does not apply below the threshold). Statements with no practical measures. No process for verifying employment status of subcontracted or agency labour.

Pulling It All Together

These eight areas form an interconnected management system, not independent silos. Your health and safety policy references your risk assessments. Your RAMS flow from those assessments. Your training records demonstrate the competence to implement your RAMS. Your insurance provides the financial backstop.

Assessors are looking for coherence as much as completeness. A business with all eight areas covered but obvious inconsistencies — different employee numbers in different documents, policies referencing procedures not followed — raises more concerns than one with a minor gap that demonstrates genuine engagement.

The Three Schemes at a Glance

Pricing is subject to change and varies by company size and tier. Last reviewed: February 2026. Always check current fees directly with each scheme.

CHAS: What It Covers and Who Recognises It

CHAS began as a local authority initiative to standardise health and safety vetting of contractors. Its roots in public-sector procurement remain strong — if you work for councils, housing associations, or public-sector facilities teams, CHAS is very likely to be requested. For a step-by-step walkthrough of the application process, see our guide to getting CHAS accreditation.

CHAS Standard focuses squarely on health and safety: policy, risk assessments, safe systems of work, training, incident reporting, insurance, and subcontractor management. It is a focused, health-and-safety-specific assessment that satisfies the core SSIP requirements.

CHAS Premium Plus extends the assessment into environmental management, quality management, financial standing, anti-bribery and corruption, modern slavery, and equal opportunities. This broader scope brings it closer to what Constructionline Gold covers, and is increasingly requested by clients who want a single assessment covering multiple compliance areas.

Strongest in: Local authority work, housing associations, public-sector maintenance, and smaller principal contractor supply chains. CHAS is often the first accreditation that SME subcontractors are asked to hold.

Constructionline: What It Covers and Who Recognises It

Constructionline operates differently from CHAS and SafeContractor. Rather than being purely an assessment scheme, it functions as a national register of prequalified contractors and consultants. Buyers — particularly in the public sector and Tier 1 contractor supply chains — use Constructionline as a database to find and verify prequalified suppliers.

Silver covers basic company verification, financial assessment (using Dun & Bradstreet data), insurance verification, and health and safety assessment aligned to the SSIP Common Assessment Standard.

Gold adds environmental management, quality management, equal opportunities, and anti-bribery assessment. Gold is the level most commonly required by Tier 1 contractors and larger public-sector frameworks.

Platinum extends into corporate social responsibility and behavioural assessment — less commonly required for SMEs but relevant for major frameworks.

Strongest in: Tier 1 contractor supply chains, central government procurement, NHS and education-sector work. If a Tier 1 contractor tells you to "get on Constructionline," they typically mean Silver as a minimum, often Gold.

SafeContractor: What It Covers and Who Recognises It

SafeContractor is a health and safety prequalification scheme with strong penetration in facilities management, commercial maintenance, and the broader services sector. It has significant reach in construction, particularly in fit-out, refurbishment, and maintenance work.

The core assessment covers health and safety competence, risk assessments, method statements, training records, and insurance — very similar in scope to CHAS Standard. Extended options allow you to add environmental management and quality management modules.

Strongest in: Facilities management, commercial property maintenance, retail fit-out, and corporate services. SafeContractor is often the specified requirement for work in occupied commercial buildings, shopping centres, offices, and similar environments.

SSIP Mutual Recognition: Does One Cover All Three?

All three schemes are SSIP members, which means they assess against the Common Assessment Standard (CAS) for health and safety. In theory, achieving one SSIP assessment means the others should recognise it through mutual recognition (the "deem to satisfy" mechanism).

In practice, mutual recognition works for the core health and safety component. However:

• Constructionline is a register, not just an assessment. Buyers searching Constructionline for suppliers will not find you unless you are registered with Constructionline specifically — having CHAS or SafeContractor does not add you to the Constructionline database.
• Extended modules (environmental, quality, financial) are scheme-specific and fall outside SSIP mutual recognition. Having CHAS Premium Plus does not automatically satisfy Constructionline Gold requirements.
• Client specifications often name a specific scheme. If a tender document says "Constructionline Gold required," holding CHAS Premium Plus may not be accepted — even if the assessment scope is comparable.

The bottom line: SSIP mutual recognition reduces duplication for the health and safety element, but it does not make the schemes fully interchangeable in practice.

Detailed Comparison: Assessment Areas

Which Should You Get First?

The right choice depends on where your work comes from and where you want it to come from. Here are the most common scenarios:

Scenario 1: You primarily work for local authorities and housing associations

Recommendation: Start with CHAS Standard.

CHAS has the deepest roots in local authority procurement. It is widely specified in council tender documents and housing association prequalification requirements. CHAS Standard provides the core health and safety assessment at a relatively accessible price point. If your clients begin asking for broader compliance coverage, you can upgrade to Premium Plus later.

Scenario 2: You are targeting Tier 1 contractor supply chains

Recommendation: Start with Constructionline Gold.

Most major Tier 1 contractors — Balfour Beatty, Kier, Morgan Sindall, Willmott Dixon, and others — use Constructionline as their primary or secondary supply chain register. Being on the register at Gold level is often a hard requirement for inclusion in their supply chain. Without it, your business may simply not appear in their procurement searches.

Scenario 3: You work in facilities management, maintenance, or commercial fit-out

Recommendation: Start with SafeContractor.

SafeContractor has the strongest recognition in FM and commercial maintenance environments. If your clients are property managers, retail chains, or corporate occupiers, SafeContractor is likely to be the scheme they specify.

Scenario 4: You work across multiple sectors

Recommendation: Start with whichever scheme your largest or most frequent clients require, then add a second based on your growth pipeline. Many established SMEs hold two or all three.

Scenario 5: You are just starting out

Recommendation: Start with CHAS Standard. It is widely recognised, relatively accessible on cost, and through SSIP mutual recognition gives you visibility across the broader scheme network.

Do You Need All Three?

Not necessarily. The decision should be driven by client requirements, not by a desire to collect certificates. Check your current and target clients' tender documents and supply chain portals, and ensure the annual fees are justified by the work each scheme opens up.

Regardless of which scheme you choose, the underlying documentation requirements are substantially the same. Use our Construction Accreditation Readiness Scorer to benchmark your position and identify gaps before you apply.

Summary

CHAS, Constructionline, and SafeContractor each serve the same fundamental purpose — prequalifying contractors — but they serve different parts of the market and assess at different levels of depth. Choose based on where your work comes from, not on which scheme seems easiest. Prepare your documentation thoroughly before applying (our pillar guide to prequalification covers the full documentation requirements), and treat the assessment process as an opportunity to strengthen your management systems, not just a box-ticking exercise.

It is widely reported in the industry that the majority of first-time CHAS applicants are referred back for additional information or corrections. The guidance below is designed to help you pass first time.

What Is CHAS?

CHAS is a health and safety assessment scheme that evaluates whether your business has adequate health and safety management arrangements in place. Originally established by a consortium of local authorities, it has grown into one of the UK's most recognised contractor assessment schemes, used across both public and private sectors.

CHAS is a member of SSIP (Safety Schemes in Procurement), which means a CHAS assessment is recognised by other SSIP member schemes through mutual recognition — reducing the need for duplicate assessments.

For a broader overview of how CHAS fits into the wider prequalification system, see our Complete Guide to Construction Supplier Prequalification in the UK.

CHAS Standard vs CHAS Premium Plus

CHAS offers two main tiers of assessment. Understanding the difference is important because it affects both cost and the scope of what you need to prepare.

CHAS Standard

The core health and safety assessment. This evaluates your health and safety policy, risk assessments, safe systems of work, training arrangements, incident reporting, and insurance. For many SME contractors, this is the starting point and satisfies the requirements of a large number of clients.

CHAS Premium Plus

An extended assessment that goes beyond health and safety to cover environmental management, quality management, financial standing, anti-bribery and corruption, modern slavery, and equal opportunities. Premium Plus is increasingly requested by larger clients and aligns more closely with what schemes like Constructionline Gold assess.

Which should you choose? If your clients only ask for CHAS, Standard is sufficient. If you are tendering for larger contracts or working with clients who have broader compliance requirements, Premium Plus provides more comprehensive coverage and may save you pursuing additional assessments separately.

Documentation You Need Before Applying

The single biggest reason applications fail is incomplete or inadequate documentation. Before you start the application, gather and review every item on this list.

1. Health and Safety Policy

Your policy must be signed by a director or owner, dated within the last 12 months, and specific to your business activities. A generic template downloaded from the internet will almost certainly be flagged. The policy should include a general statement of intent, organisation and responsibilities (named individuals), and arrangements for implementing the policy in practice.

2. Risk Assessments

Activity-specific risk assessments for the work your business carries out. These must demonstrate that you have identified the significant hazards associated with your operations and put proportionate controls in place. Assessors look for evidence that risk assessments are living documents — reviewed regularly and updated when circumstances change.

3. Method Statements and RAMS

Risk Assessment Method Statements (RAMS) for high-risk activities. These should show a clear, step-by-step approach to carrying out work safely, referencing the relevant risk assessments, required PPE, competence requirements, and emergency procedures.

4. Insurance Certificates

Current certificates for:

• Employers' liability insurance — minimum £5 million (many principal contractors require £10 million)
• Public liability insurance — typically £5 million minimum, though requirements vary by client
• Professional indemnity insurance — if you provide design or consultancy services

Certificates must be current and cover the period of assessment. Expired certificates are one of the most common and most avoidable reasons for referral.

5. Training Records

Evidence that your workforce holds appropriate competence qualifications:

• CSCS cards for operatives
• SMSTS (Site Management Safety Training Scheme) for site managers
• SSSTS (Site Supervisors Safety Training Scheme) for supervisors
• Trade-specific qualifications (e.g., IPAF, PASMA, asbestos awareness)
• First aid at work certificates
• Evidence of ongoing training and toolbox talks

6. Evidence of Competent Health and Safety Advice

Under the Management of Health and Safety at Work Regulations 1999, you must have access to competent health and safety advice. This could be an in-house competent person (with appropriate qualifications such as NEBOSH) or a retained external health and safety consultant. You will need to provide evidence of this arrangement.

7. Environmental Policy (Premium Plus)

A written environmental policy covering waste management, pollution prevention, energy use, and environmental awareness training. For SMEs, this does not need to be ISO 14001 certified, but it must demonstrate genuine engagement with environmental responsibilities relevant to your operations.

8. Additional Policies (Premium Plus)

For Premium Plus, you will also need: equal opportunities policy, modern slavery statement, anti-bribery and corruption policy, and quality management procedures.

Use our Health & Safety Documentation Checklist to systematically check every requirement before you start the application.

Step-by-Step Application Process

Step 1: Audit Your Current Documentation

Before you spend anything on application fees, conduct an honest internal audit. Review each document against the requirements listed above. Check dates, signatures, specificity, and completeness. This is where most of the real work happens — the application itself is simple once your documentation is sound.

Step 2: Fill the Gaps

Address every issue identified in your audit. Rewrite generic policies to reflect your actual operations. Update risk assessments. Renew expired insurance. Ensure training records are complete and current. If you do not have access to competent health and safety advice, arrange this before applying.

Step 3: Choose Your Tier

Decide whether CHAS Standard or Premium Plus is appropriate for your business needs and client requirements. If in doubt, start with Standard — you can upgrade later.

Step 4: Register and Create Your Account

Visit the CHAS website and create an account. You will need to provide basic company information including registered company name, company number, business activities (using SIC codes and work category descriptions), number of employees, and contact details for the person managing the application.

Step 5: Complete the Online Application

The application is completed through the CHAS online portal. You will answer a series of questions about your health and safety management arrangements and upload supporting documentation. Answer honestly and specifically — vague or generic responses are a common trigger for referral.

Step 6: Upload Supporting Documents

Upload all the documentation outlined above. Ensure files are clearly named (e.g., "HS_Policy_2026_Signed.pdf" rather than "Document1.pdf"), legible, and complete. Missing pages or illegible scans cause delays.

Step 7: Pay the Application Fee

Fees vary by company size and tier. Check the current fee schedule on the CHAS website before applying — fees are reviewed regularly and are subject to change.

Step 8: Assessment Review

A CHAS assessor will review your application and documentation. This typically takes between one and four weeks, depending on the volume of applications and the completeness of your submission.

Step 9: Respond to Any Queries

If the assessor needs additional information or clarification, you will receive a notification through the portal. Respond promptly and thoroughly — incomplete responses to queries lead to further rounds of referral and delay.

Step 10: Receive Your Certificate

Once the assessor is satisfied that your arrangements meet the required standard, you will receive your CHAS certificate, valid for 12 months. You will be listed on the CHAS database, visible to buyers searching for prequalified contractors.

Common Reasons Applications Fail

Understanding why applications fail helps you avoid the same pitfalls. The most frequently reported issues include:

Generic or Template Policies

Assessors can spot a downloaded template immediately. Your health and safety policy must reflect your business — the specific activities you carry out, the hazards your workforce encounters, and the control measures you actually implement. A bricklaying contractor's policy should read very differently from an electrical contractor's.

Outdated Documentation

Policies not reviewed within 12 months, expired insurance certificates, lapsed training qualifications. If a document has a date on it, the assessor will check it. Build a rolling review schedule so nothing expires unnoticed.

Incomplete Risk Assessments

Risk assessments that do not cover your core activities, or that identify hazards without specifying adequate control measures. Assessors are looking for evidence that you genuinely engage with the risk assessment process, not that you have ticked a box.

No Evidence of Competent Advice

Failing to demonstrate access to competent health and safety assistance is a fundamental compliance gap. This is a legal requirement, and assessors will look for evidence of either an in-house competent person or a retained external adviser.

Poor Presentation and Organisation

Illegible documents, unclear file names, missing pages, and disorganised submissions all slow the process and increase the likelihood of referral. Treat the application as you would a tender submission — clear, professional, and complete.

Mismatched Information

Inconsistencies between your application answers and your uploaded documents. If your policy says you employ 30 people but your application says 15, the assessor will query it. Ensure everything aligns.

How Long Does CHAS Last?

CHAS accreditation is valid for 12 months from the date of issue. You will need to renew annually, which involves a reassessment of your documentation and management arrangements. Many contractors find the renewal process smoother than the initial application — provided they maintain their systems throughout the year rather than scrambling to update everything at renewal time.

Preparing for Success

The contractors who pass first time share common traits: they prepare thoroughly before applying, they treat their health and safety management systems as operational tools rather than paperwork exercises, and they present their documentation clearly and professionally.

If you are unsure whether your business is ready to apply, start with our Construction Accreditation Readiness Scorer for a quick assessment, then use the Health & Safety Documentation Checklist to identify specific gaps. Work through each area systematically, and only submit your application once you are confident that every requirement is covered.

The investment of time upfront pays for itself — not just in avoiding failed applications and wasted fees, but in building health and safety systems that genuinely protect your workforce and your business.

This guide breaks down the prequalification process, from the major schemes and standards to practical steps for getting your business assessment-ready.

What Is Construction Supplier Prequalification?

Supplier prequalification is the process by which clients, principal contractors, and public-sector buyers verify that a contractor or subcontractor meets minimum standards before being invited to tender. In construction, this overwhelmingly focuses on health and safety management, but increasingly extends to environmental management, financial standing, equality, and modern slavery compliance.

For decades, prequalification was fragmented — every main contractor had their own questionnaire, and subcontractors would spend weeks filling in near-identical forms. The industry has since consolidated around a handful of recognised assessment schemes and a common framework, but the system remains confusing for many SMEs entering the supply chain for the first time.

The Common Assessment Standard (CAS) and PAS 91

Before looking at individual schemes, it is worth understanding the frameworks that underpin them.

PAS 91: Construction Prequalification Questionnaires

PAS 91 is a Publicly Available Specification published by BSI (British Standards Institution). It provides a standardised format for prequalification questionnaires in construction. The aim is simple: reduce duplication by ensuring that the questions asked during prequalification follow a consistent structure, regardless of who is asking.

PAS 91 covers core modules including company information, financial information, health and safety, equal opportunity and diversity, environmental management, and quality management. Many public-sector procurement exercises reference PAS 91 directly, and the major assessment schemes broadly align their assessment criteria with it.

The Common Assessment Standard (CAS)

The Common Assessment Standard is the framework that ties the major health and safety assessment schemes together. Developed under the Safety Schemes in Procurement (SSIP) umbrella, CAS sets out the core health and safety criteria that all SSIP member schemes must assess against.

The practical effect for contractors: if you achieve accreditation through one SSIP member scheme, other SSIP members should recognise that assessment through a process called mutual recognition (sometimes referred to as "deem to satisfy"). This is designed to prevent contractors needing multiple, overlapping assessments.

In practice, mutual recognition works well for the core health and safety element, though individual schemes often have additional modules — financial assessment, environmental management, or sector-specific checks — that fall outside the CAS scope and require separate assessment.

The Major Prequalification Schemes

Four schemes dominate UK construction prequalification. Each operates slightly differently, serves different parts of the supply chain, and offers varying levels of assessment.

CHAS (Contractors Health and Safety Assessment Scheme)

CHAS is one of the most widely recognised health and safety assessment schemes in UK construction. Originally established by local authorities to standardise contractor vetting, it has grown into a national scheme used across both public and private sectors.

What it assesses: Health and safety policy, risk assessment competence, method statements, training arrangements, accident reporting, insurance, and management of subcontractors. The CHAS Premium Plus tier extends into environmental management, quality management, financial assessment, anti-bribery, and modern slavery.

Who uses it: Local authorities, housing associations, facilities management companies, and an increasing number of Tier 1 and Tier 2 contractors. CHAS is often the first scheme that SME contractors encounter.

Tiers: CHAS Standard (core health and safety) and CHAS Premium Plus (extended assessment covering additional compliance areas).

SSIP member: Yes. Core health and safety assessment is mutually recognised by other SSIP members.

Constructionline

Constructionline is the UK's largest register of prequalified contractors and consultants for the construction industry. Backed by government and managed by Capita, it is heavily used in public-sector procurement and by many Tier 1 contractors as a prequalification gateway.

What it assesses: Constructionline operates at three levels — Silver, Gold, and Platinum. Silver covers basic company verification, financial checks, insurance, and health and safety (aligned to CAS through its SSIP membership). Gold adds environmental management, quality management, equal opportunities, and anti-bribery. Platinum adds behavioural assessments and corporate social responsibility.

Who uses it: Central government departments, local authorities, NHS trusts, major Tier 1 contractors (many of whom use Constructionline as their primary supply chain register), housing associations, and utilities.

SSIP member: Yes, at Silver level and above for the health and safety component.

SafeContractor

SafeContractor is a health and safety prequalification scheme particularly prevalent in facilities management, maintenance, and commercial services, though it has significant reach in construction.

What it assesses: Health and safety competence, risk assessment, method statements, training, and insurance. Like CHAS, it also offers extended assessment options covering environmental and quality management.

Who uses it: Facilities management companies, commercial landlords, retail chains, and a range of construction clients — particularly in fit-out, maintenance, and refurbishment sectors.

SSIP member: Yes. Core health and safety assessment is mutually recognised.

For a detailed comparison between these three schemes, see our guide: CHAS vs Constructionline vs SafeContractor: Which Do You Need?.

SSIP (Safety Schemes in Procurement)

SSIP is not itself an assessment scheme that you apply to directly. It is the umbrella body that sets the Common Assessment Standard and manages mutual recognition between its member schemes. When someone says a contractor is "SSIP assessed," they mean the contractor holds a valid certificate from an SSIP member scheme — such as CHAS, Constructionline, SafeContractor, SMAS Worksafe, Acclaim Accreditation, or one of the other members.

The key benefit for contractors: one assessment, recognised across multiple scheme members. The key limitation: mutual recognition covers the core health and safety element only. Extended modules (environmental, financial, quality) typically need separate assessment.

Beyond Health and Safety: What Else Gets Assessed

While health and safety remains the cornerstone of construction prequalification, the scope of assessment has expanded significantly. Most principal contractors and public-sector buyers now expect evidence across several additional areas:

Financial Standing

Buyers want confidence that you will not go insolvent mid-project. Constructionline uses Dun & Bradstreet data; CHAS Premium Plus includes its own financial checks. Even where a scheme does not assess this formally, expect principal contractors to run their own credit checks.

Environmental Management

An environmental policy, waste management procedures, and (for larger contracts) an Environmental Management System aligned to ISO 14001. This is increasingly a baseline expectation, not a differentiator.

Equal Opportunities and Diversity

A written equal opportunities policy, evidence of fair recruitment practices, and increasingly, reporting on workforce diversity metrics. This is assessed at Gold/Premium Plus level by most schemes.

Modern Slavery

A modern slavery statement (mandatory for businesses with turnover above £36 million, but increasingly expected as good practice for smaller firms), evidence of supply chain due diligence, and worker welfare procedures.

Quality Management

Documented quality procedures, inspection and test plans, defect management, and (for larger firms) a Quality Management System aligned to ISO 9001.

For a detailed breakdown of what assessors check across all these areas, see our guide: Construction Accreditation Requirements: What Tier 1 Contractors Actually Check.

Which Scheme Should You Get First?

This is the question every SME contractor asks, and the answer depends on your target market:

If you work primarily for local authorities or housing associations: CHAS is typically the most recognised and often the most requested.

If you are targeting Tier 1 contractor supply chains or public-sector frameworks: Constructionline (at least Silver, often Gold) is frequently a mandatory requirement. Many Tier 1 contractors use Constructionline as their primary supply chain database.

If you work in facilities management, maintenance, or commercial fit-out: SafeContractor is widely recognised in these sectors and is often the default requirement.

If budget is tight: Start with one scheme. Thanks to SSIP mutual recognition, you gain visibility across the wider network. CHAS Standard is often the most accessible entry point for SMEs.

If you want maximum coverage: Many established SMEs hold two or even all three, particularly if they work across multiple sectors. The investment is significant but opens the widest range of opportunities.

How to Prepare for Prequalification Assessment

Regardless of which scheme you pursue, the documentation requirements overlap substantially. Getting your house in order before you apply saves time, reduces the risk of failure, and ensures your systems are genuinely robust — not just paperwork exercises.

Core Documentation You Need

1. Health and safety policy — Signed by a director, reviewed within the last 12 months, specific to your operations (not a generic template).
2. Risk assessments — Activity-specific, regularly reviewed, demonstrating genuine engagement with the hazards your workforce faces.
3. Method statements and RAMS — Showing how you plan and control high-risk activities on site.
4. Insurance certificates — Employers' liability (minimum £10 million for most principal contractors), public liability, and professional indemnity where applicable.
5. Training records — CSCS cards, SMSTS/SSSTS, trade-specific qualifications, and evidence of ongoing CPD.
6. Environmental policy — Appropriate to your scale, covering waste management, pollution prevention, and environmental awareness.
7. Equal opportunities policy — Written policy with evidence of implementation.
8. Modern slavery statement — Even below the statutory threshold, a proportionate statement demonstrates supply chain awareness.

Use our Health & Safety Documentation Checklist to audit your current position before applying.

Common Reasons for Failure

Assessment bodies report that a significant proportion of first-time applicants are referred back for additional information or fail outright. The most common issues include:

• Generic, template policies that have not been tailored to the business or its activities
• Out-of-date documents — particularly health and safety policies not reviewed in the last 12 months
• Missing or incomplete risk assessments for core activities
• No evidence of competent health and safety advice (either in-house or through an external consultant)
• Insurance gaps — policies that have lapsed, or cover levels below client requirements
• Lack of training records — particularly for site supervisors (SMSTS/SSSTS) and operatives (CSCS)

Using TenderReady to Assess Your Readiness

Before you spend money on application fees, it pays to understand where you stand. Our Construction Accreditation Readiness Scorer analyses your current documentation, policies, and management systems against the criteria used by the major schemes, giving you a clear picture of what needs work before you apply.

Summary

UK construction prequalification is built around a handful of key schemes — CHAS, Constructionline, and SafeContractor — operating under the SSIP umbrella and aligned to the Common Assessment Standard. Understanding which scheme (or schemes) your target clients recognise, preparing your documentation thoroughly before applying, and maintaining your systems year-round rather than scrambling at renewal time will put your business in the strongest possible position.

Start by assessing your readiness with our Construction Accreditation Readiness Scorer, then work through the specific documentation requirements using our Health & Safety Documentation Checklist.
