Construction Accreditation Costs: CHAS, Constructionline & SafeContractor
Ask a contractor what accreditation costs and they will quote the annual fee. That is only part of the picture.
The headline membership fee — the number on the scheme's website — is real enough. But it is not the total cost of getting accredited and staying accredited. When you add up the preparation time, potential consultant fees, document revisions, the cost of failing and resubmitting, and the annual renewal cycle, the true cost of accreditation is significantly higher than the sticker price.
This guide breaks down the full cost of construction accreditation for UK SMEs: scheme fees, hidden costs, and practical strategies for keeping the total spend under control.
Scheme Fee Comparison
The table below compares annual membership fees across the major schemes and tiers. All figures are indicative ranges based on publicly available pricing for small to medium-sized contractors. Schemes typically price by employee count or annual turnover — your actual fee may differ.
Where a scheme publishes a starting price, the published figure is given and marked as such — those were verified against each scheme's own pricing page in October 2026. Rows marked "not published" are schemes that quote individually. Fees change regularly and scale with your size — always confirm current pricing directly with each scheme before applying.
| Scheme | Tier | Indicative Annual Fee (SME) | What It Covers |
|---|---|---|---|
| CHAS | Standard | From £429 (published) | Core H&S assessment (SSIP) |
| CHAS | Advanced | From £659 (published) | SSIP + the former PAS 91 scope |
| CHAS | Elite | From £949 (published) | SSIP + Common Assessment Standard: environmental, quality, financial, equality, modern slavery, anti-bribery |
| Constructionline | Silver | From £649 at the lowest turnover band (£599 with a valid SSIP), ex VAT, plus £99 joining fee; rises with turnover (verified October 2026) | Company verification, financial standing, H&S (SSIP included), insurance |
| Constructionline | Gold | From £749 at the lowest turnover band (£699 with a valid SSIP), ex VAT, plus £99 joining fee; rises with turnover (verified October 2026) | Silver + Common Assessment Standard (desktop) |
| Constructionline | Platinum | From £3,199 at the lowest turnover band (£3,149 with a valid SSIP), ex VAT, plus £99 joining fee; rises with turnover (verified October 2026) | Gold + a one-day premises audit |
| SafeContractor | Standard | From £419 (published, verified October 2026) | Core H&S assessment (SSIP) |
| SMAS Worksafe | Worksafe | From £345 (published) | Core H&S assessment (SSIP) |
| SMAS Worksafe | Worksafe Plus | From £565 (published) | SSIP + environmental and quality (the tier SMAS labels "formerly PQQ") |
| SMAS Worksafe | Worksafe Pro | From £725 (published) | SSIP + Common Assessment Standard |
| Once For All Health & Safety (formerly Acclaim) | Standard | Not published — quoted by turnover | Core H&S assessment (SSIP); included with paid Constructionline memberships |
Key notes:
- Fees are annual. Every scheme requires 12-month renewal.
- Most schemes scale fees by company size (employee count or turnover). A sole trader pays less than a 50-person contractor.
- Some schemes offer multi-year packages or early renewal discounts.
- VAT may or may not be included in quoted figures — check the small print.
Model these fees against your own business size and shortlist with our Accreditation Cost Calculator. For a detailed comparison of what each scheme covers beyond price, see our CHAS vs Constructionline vs SafeContractor guide.
The Costs Nobody Mentions
Scheme fees are transparent. The rest of the cost is not. For a realistic budget, you need to account for every element below.
1. Document Preparation Time
This is the biggest hidden cost for most SMEs, and it is paid in time rather than money.
If your health and safety policy, risk assessments, method statements, training records, and insurance certificates are already in good order, preparation might take a few hours of assembly and review. If they are not — and for first-time applicants, they often are not — you are looking at days or weeks of work.
A realistic preparation estimate for a first-time applicant:
| Task | Estimated Time |
|---|---|
| Write or update H&S policy | 4-8 hours |
| Write activity-specific risk assessments | 8-20 hours (depending on scope of activities) |
| Draft method statements for high-risk work | 4-12 hours |
| Compile training records and chase missing certificates | 4-8 hours |
| Verify and gather insurance certificates | 1-2 hours |
| Write environmental policy (Constructionline Gold / CHAS Elite) | 2-4 hours |
| Write quality procedures (Constructionline Gold / CHAS Elite) | 3-6 hours |
| Write equal opportunities and anti-bribery policies (CHAS Elite; Constructionline asks for an anti-bribery policy from Silver and equal opportunity from Gold) | 2-4 hours |
| Complete online application and upload documents | 2-4 hours |
| Total (basic H&S tier) | 23-54 hours |
| Total (extended tier, e.g. Gold) | 30-68 hours |
For a director or office manager earning £25 to £40 per hour, that preparation time has a real monetary value. At 40 hours and £30/hour, the internal labour cost alone is £1,200 — likely more than the scheme fee itself.
2. Health and Safety Consultant Fees
Many SMEs engage a health and safety consultant to prepare their documentation or review it before submission. Consultant involvement ranges from a light-touch review to full document preparation.
Indicative consultant fee ranges. Unlike the scheme fees above, these are not published figures — no consultant operates a public tariff, so the ranges below are market estimates drawn from common industry pricing. Treat them as a planning range, not a quote:
| Service | Indicative Cost |
|---|---|
| Documentation review and gap analysis | £295-£500 |
| Full document preparation (policies, risk assessments, RAMS) | £800-£2,000+ |
| Ongoing retained H&S advisory service (annual) | £1,200-£3,600+ |
| One-off accreditation application support | £500-£1,500 |
Some consultants offer bundled packages — "CHAS-ready" or "Constructionline Gold preparation" — that include document drafting, application completion, and query handling. These can represent reasonable value if your documentation is starting from a low base, but verify exactly what is included before committing.
A word of caution: engaging a consultant to prepare your documentation does not remove your obligation to understand and implement what those documents say. Assessors can and do ask questions that test whether the applicant actually uses the systems described in their submission. If your consultant wrote it but you have never read it, that will become apparent. The Management of Health and Safety at Work Regulations 1999, Regulation 7 (Great Britain; Northern Ireland has the same duty in regulation 7 of its 2000 Regulations), requires employers to appoint competent persons (a competent sole trader or partnership can be exempt) — but the responsibility for health and safety remains with the employer.
3. The Cost of Failing
This is the cost that SMEs most consistently underestimate.
Assessment bodies report that a significant proportion of first-time applicants are referred back for additional information. Each referral delays your accreditation, consumes more of your time, and in some cases triggers additional fees.
The costs of failure include:
- Time spent responding to assessor queries — typically 2 to 8 hours per round
- Resubmission fees — some schemes charge for reassessment if the initial submission is substantially inadequate
- Delayed contract opportunities — if you needed accreditation to meet a tender deadline, a failed first attempt may cost you the opportunity entirely
- Consultant remediation fees — if you engaged a consultant to fix what went wrong, expect additional charges
The most cost-effective accreditation is one that passes first time. Our guides to CHAS accreditation, Constructionline Gold, and SafeContractor accreditation each cover the most common failure points and how to avoid them.
4. Renewal Costs
Accreditation is not a one-off purchase. Every major scheme operates on an annual renewal cycle. The renewal fee is typically similar to the initial fee, plus you need to invest time updating documentation, refreshing policies, and ensuring all training and insurance certificates remain current.
Over a five-year period, a single scheme at Gold level might cost:
| Year | Fee | Preparation/Update Time (hours) | Estimated Total |
|---|---|---|---|
| Year 1 (initial) | ~£600 | 40-60 | £1,800-£2,400 |
| Year 2 (renewal) | ~£600 | 8-16 | £840-£1,080 |
| Year 3 (renewal) | ~£600 | 8-16 | £840-£1,080 |
| Year 4 (renewal) | ~£600 | 8-16 | £840-£1,080 |
| Year 5 (renewal) | ~£600 | 8-16 | £840-£1,080 |
| 5-year total | ~£3,000 | ~£5,160-£6,720 |
Based on a £600 annual fee and internal labour cost of £30/hour. Actual figures will vary.
If you hold two or three schemes, multiply accordingly.
5. The Opportunity Cost of NOT Having Accreditation
This is the cost that justifies the entire investment.
Construction SMEs without recognised accreditation are excluded from a large and growing segment of the market. Tier 1 contractors require it. Public-sector frameworks require it. Facilities management companies require it. Housing associations require it. Without accreditation, you cannot pass prequalification — and if you cannot pass prequalification, you cannot tender.
It is difficult to put a precise figure on missed opportunities, but consider: if accreditation opens up even one additional contract per year worth £50,000, the return on a £2,000 annual accreditation investment is substantial. For most SMEs, the question is not whether they can afford accreditation but whether they can afford to operate without it.
Cost-Saving Strategies for SMEs
1. Prepare Thoroughly Before Applying
The single most effective cost-saving measure is passing first time. Every referral, resubmission, and query response costs you time and delays your accreditation. Use our Construction Accreditation Readiness Scorer and Health & Safety Documentation Checklist before you submit anything.
2. Use SSIP Mutual Recognition
All major construction accreditation schemes — CHAS, Constructionline, SafeContractor, SMAS, Once For All Health & Safety, and others — are SSIP members, though not all in the same category: CHAS, SafeContractor, SMAS, Once For All and CQMS are Registered Members that carry out SSIP assessments, while Constructionline is a Supporter Member whose membership bundles an SSIP delivered by Once For All Health & Safety. Mutual recognition means that the core health and safety assessment from one scheme is recognised by the others.
In practice, this means:
- If you hold CHAS and a client asks for SafeContractor, the H&S component may be transferred without a full reassessment
- You avoid paying for the same health and safety assessment twice
- Extended modules (environmental, quality, financial) fall outside mutual recognition and may still require separate assessment
Mutual recognition does not eliminate the need for multiple schemes entirely — clients who specify a named scheme may not accept a substitute — but it reduces the duplication. For a detailed explanation, see our SSIP guide.
3. Start With One Scheme
If budget is tight, start with the single scheme your most important clients require. Get it right, maintain it well, and add a second scheme when your pipeline justifies the investment. Trying to achieve three accreditations simultaneously multiplies the preparation burden and the cost. For the cheapest SSIP options, see our budget scheme comparison — PQS publishes an SSIP certificate from £99 + VAT.
For guidance on which scheme to prioritise based on your target market, see our scheme comparison guide.
4. Build Systems, Not Just Documents
The cheapest accreditation renewal is one where your documentation is already up to date because you actually use it. If your health and safety policy sits in a drawer, you will spend days updating it at renewal. If it is a working document that you review quarterly and reference in toolbox talks, renewal becomes a quick verification rather than an annual rewrite.
This is not just a cost argument — it is a compliance argument. The Health and Safety at Work etc. Act 1974 and the Management of Health and Safety at Work Regulations 1999 require you to manage health and safety as an ongoing function of your business, not as an annual paperwork exercise. Building genuine systems pays for itself in reduced preparation time, fewer assessor queries, and better outcomes on site. See our construction health and safety policy guide for practical advice on building a policy that works beyond the assessment.
5. Consider the Timing of Your Application
Most schemes experience a surge in applications in the first quarter of the calendar year (January to March), as businesses prepare for the public-sector financial year-end and the busy tendering season. Assessment turnaround times are typically faster — and you may get more thorough, less rushed assessor attention — if you apply outside the peak period.
6. Keep Insurance Under Review
Insurance is a significant cost in its own right, and accreditation requirements can affect what you need. Employers' liability at £10 million (rather than the statutory £5 million minimum) is the standard expectation for Tier 1 supply chain work. The £5 million figure comes from regulation 3(1) of the Employers' Liability (Compulsory Insurance) Regulations 1998, which requires cover that "shall in aggregate be not less than £5 million in respect of ... any one occurrence"; the Employers' Liability (Compulsory Insurance) Act 1969 imposes the duty to insure but sets no amount. Public liability at £5-10 million is typical. Professional indemnity is required if you provide any design input.
Use our Construction Insurance Requirements Calculator to check whether your cover aligns with accreditation and client requirements. Paying for more cover than you need is wasteful; being underinsured is worse.
What Does Accreditation Actually Cost? A Worked Example
Here is a total cost breakdown for a 20-person subcontractor pursuing Constructionline Gold and CHAS Standard in their first year. The CHAS fee is CHAS's own price for this headcount; the Constructionline fee depends on your turnover band, so that cell points to Constructionline's price calculator; everything else is an estimate.
| Cost Element | Constructionline Gold | CHAS Standard |
|---|---|---|
| Scheme fee | your turnover band's published price — run Constructionline's price calculator (from £749 at the lowest band, £699 with a valid SSIP, ex VAT) | £1,179 — CHAS's own "Get Your Price" figure for 16-30 employees (verified October 2026; "From £429 per year" is its owner-operator price) |
| Document preparation (internal time) | ~£900-£1,500 (30-50 hrs @ £30/hr) | ~£300-£600 (shared prep with above) |
| H&S consultant review | ~£400-£800 | Included if same consultant |
| Insurance (incremental, if upgrade needed) | Varies | Varies |
| Year 1 total per scheme | your Constructionline price + ~£1,300-£2,300 | ~£1,479-£1,779 |
| Combined Year 1 total | your Constructionline price + ~£2,779-£4,079 |
In subsequent years, if documentation is maintained, the preparation and consultant cost drops substantially; the two scheme fees recur every year.
Only the Constructionline fee needs your own figures: it depends on your turnover band, so run Constructionline's price calculator for your business. For CHAS, its own "Get Your Price" tool gives £1,179 a year for CHAS Standard at 16-30 employees (verified October 2026; the visible "from £429 a year" is its owner-operator price). SafeContractor publishes a starting price too (from £419 a year, verified October 2026) — see the table above, and our SafeContractor cost guide for what moves your quote above it. Everything else is an estimate of internal time and consultant cost. These figures will be different for every business — a well-organised contractor with existing documentation may spend far less. A business starting from scratch may spend more. The point is that the scheme fee is only part of the true first-year cost.
Which Schemes Offer the Best Value?
There is no single answer. Value depends on what each scheme opens up for your business.
- CHAS Standard offers the most accessible entry point for SMEs needing basic SSIP-recognised H&S accreditation, particularly for local authority and housing association work.
- Constructionline Gold is the strongest investment for SMEs targeting Tier 1 contractor supply chains and public-sector frameworks — it covers the broadest assessment scope and places you on the most widely used prequalification register.
- SafeContractor is worth pricing if your clients name it; facilities management, property and retail are among the sectors it says it covers.
- SMAS Worksafe is worth considering where your clients accept any SSIP scheme, with published prices from £345 (Worksafe).
For a detailed breakdown of which scheme fits which market, see our pillar guide to construction prequalification and our accreditation requirements guide.
The Bottom Line
Construction accreditation costs more than the scheme fee. For a typical SME pursuing one or two schemes, expect a first-year total cost of £1,500 to £4,500 when you account for preparation time, consultant support, and the hidden costs of getting it wrong. Ongoing annual costs drop to £800 to £2,000 per scheme once your systems are established.
The investment is justified by the work it opens up. Accreditation is the price of entry to the UK construction supply chain — and the businesses that manage it most cost-effectively are the ones that prepare properly, pass first time, maintain their systems year-round, and use SSIP mutual recognition to minimise duplication.
