CHAS Accreditation Cost: The Real Fees, Renewal Prices and Hidden Extras

If you've landed on the CHAS pricing page and moved the little employee slider around, you already know the sticker price isn't the whole story. This guide walks a small subcontractor through the real CHAS accreditation cost — the joining fee, VAT, the renewal invoice that lands twelve months later, and the things that quietly add pounds on top (resubmission fees, upgrades, and the hours you'll spend uploading the same documents you uploaded last year).

We don't sell CHAS applications and we don't disparage the scheme — this is a straight breakdown so you can budget properly before you tick the box.

TL;DR: what does CHAS accreditation actually cost?

CHAS uses dynamic, banded pricing based on your employee count and your chosen tier — Standard, Advanced, or Elite — so there is no single "CHAS price". CHAS Elite (the Common Assessment Standard tier) starts at around £539 per year for the smallest contractors, per CHAS's own guidance, with VAT on top and a joining fee for new members. Renewal is annual and doesn't drop meaningfully in year two — you're paying broadly the same fee every twelve months to stay compliant. The hidden extras that catch people out are VAT, resubmission fees if your assessment closes, upgrade costs when a main contractor asks for Elite instead of Standard, and the unpaid hours spent re-uploading the same evidence you uploaded last year. For a headline breakdown by tier, see our sibling guide on CHAS cost.

What are you actually buying from CHAS?

Before we cost it, it helps to be clear on what CHAS sells. Veriforce CHAS offers three main paid contractor packages, plus a free entry-level product (chas.co.uk products & packages):

• CHAS Foundation — free educational and prep hub. Not an accreditation. Useful for getting your documents ready before you pay.
• CHAS Standard — the entry-level paid tier. Health & safety assessment, self-certified insurance, demonstrates SSIP compliance.
• CHAS Advanced — mid-range. Adds around eight further modules (modern slavery, financial, environmental, quality, equality, etc.) and covers SSIP plus the former PAS 91 criteria.
• CHAS Elite — the top tier. Delivers the Common Assessment Standard across 13 modules, which is what most main contractors and public buyers are now asking for after PPN 03/24 (chas.co.uk on the Common Assessment Standard).

That matters for cost because the tier your client insists on is the tier you're paying for — not the tier that sounds cheapest.

How is the CHAS accreditation cost calculated?

CHAS explicitly uses a "dynamic pricing system" where prices vary by accreditation level and by the number of employees your business has (chas.co.uk/chas-standards). Their FAQ is also clear that "the number of employees" includes direct employees, PAYE staff, permanent, temporary, part-time and labour-only subcontractors — bona-fide subcontractors with their own tools and insurance are excluded (chas.co.uk FAQ).

That definition trips people up. If you're a 6-man electrical firm but you regularly use 3 labour-only mates on the books, CHAS counts you as a 9-employee organisation for pricing. Under-declaring is not a saving — it's a problem waiting to surface at renewal.

On top of that:

• Prices exclude VAT. Every headline figure on chas.co.uk needs 20% added (chas.co.uk/chas-standards).
• A joining fee applies to new members — CHAS states this on the standards page but doesn't publish a fixed figure; check your live quote.
• The starting point is £539/year for CHAS Elite (Common Assessment Standard), according to CHAS's own blog (How to Get Common Assessment Standard Certification, CHAS) — the smallest headcount, cheapest tier.

A worked example: what a 10-engineer M&E subcontractor really pays

Rather than list bands you can already see on the CHAS slider, here's the shape of the invoice for a fictional 10-engineer mechanical/electrical firm — call them Mick's M&E Ltd — being asked by a main contractor for CHAS Elite so they can stay on a commercial maintenance framework.

The pattern to notice: year two isn't cheaper. There's no discount for having done it before. The joining fee falls away, but the annual fee is broadly the same and every certificate you rely on (Employers' Liability, Public Liability, waste carrier, F-Gas, NICEIC, Gas Safe) has to be re-uploaded — often because it has expired and been renewed in the meantime.

What are the hidden extras in the CHAS accreditation cost?

These are the line items that don't appear on the pricing slider but land on real invoices.

1. VAT on everything

CHAS quotes ex-VAT. That's normal for B2B but easy to miss when you're comparing schemes. Add 20% to every figure you see on chas.co.uk (chas.co.uk/chas-standards). If you're VAT-registered you'll recover it; if you're under the threshold, it's a real 20% on top.

2. The joining fee for new members

CHAS confirms on its standards page that "a joining fee will be applicable for new members" without publishing the figure (chas.co.uk/chas-standards). Always ask for it broken out on your quote — it's a year-one only cost, and if you're comparing CHAS to SafeContractor or SMAS Worksafe, you need it in the total.

3. Resubmission and reopen fees if you fail

CHAS's FAQ is unusually candid about this. If your application closes and it's been less than 14 days, they'll reopen it for a fee — but only once. Any further failure means "a new application needing to be purchased" (chas.co.uk FAQ). That's not a scare story; it's the mechanism. A vague health & safety policy, or a training matrix that doesn't mention CDM, is enough to trigger it. See our CHAS documents checklist for the paperwork that tends to bounce.

4. Upgrading mid-year

Starting on CHAS Standard because it's cheapest, then discovering three months in that the main contractor wants CHAS Elite (Common Assessment Standard), is a real cost. You'll pay to upgrade, and your renewal date resets in ways worth checking with CHAS at the time of upgrade. If in doubt about which tier to buy, our guide on do I need more than one accreditation helps you sanity-check what your clients actually want.

5. Fast Track

Standard turnaround is up to 10 working days once your assessment is complete; Fast Track cuts that to 2 working days for an extra fee (chas.co.uk FAQ). If a tender deadline is looming, you'll pay it — factor it in.

6. The "membership expiry vs compliance expiry" trap

CHAS distinguishes between membership expiry (your annual payment date) and compliance expiry (your annual assessment renewal), and the two can drift apart (chas.co.uk FAQ). If your compliance certificate lapses even by a week, a main contractor's portal can flag you as non-compliant — which is a lost invoice, not a lost fee. We cover this drift in more detail in our guide on accreditation renewal deadlines.

7. The time cost

No scheme puts this on the invoice, but it's real. A first CHAS Elite application touches your health & safety policy, environmental policy, quality policy, equality & diversity policy, anti-bribery policy, modern slavery statement, training matrix, insurance certificates, financial statements, and a stack of RAMS examples. At renewal it's lighter — but you're still re-uploading most of it because certificates have expired and policies need a fresh review date.

Is CHAS accreditation cost worth it?

That's not a question about the fee — it's a question about your client list. CHAS is worth its cost if the main contractors and public buyers you rely on ask for it by name, or ask for the Common Assessment Standard (which CHAS Elite delivers). If your clients accept any SSIP-recognised scheme, CHAS may not be the cheapest option — see our sibling guide on the cheapest SSIP scheme and the CHAS vs SafeContractor vs Constructionline comparison before you buy.

A useful rule of thumb: if two of your top five clients specifically mention CHAS on their PQQ, the fee pays for itself the first time you keep a maintenance contract. If none of them do, you may be buying the wrong badge.

How to keep the CHAS accreditation cost as low as possible

1. 1
   Get your headcount right first. Include labour-only subcontractors, exclude bona-fide ones. Wrong headcount at signup means a corrective invoice later.
2. 2
   Use CHAS Foundation before you pay. It's free, and the Learning Pathway lets you get policies and evidence in order before the meter starts (chas.co.uk/chas-foundation).
3. 3
   Buy the tier your client actually asks for — not the one that sounds cheapest. Upgrading mid-year costs more than starting on the right tier.
4. 4
   Check for trade association discounts. Some associations (e.g. ARCA and ATaC in the asbestos sector) offer 20% off new applications and 10% off renewals for their members (arca.org.uk). If you're a member of a trade body, ask.
5. 5
   Diary compliance expiry, not just membership expiry. They're different dates and the compliance one is what main contractor portals check.
6. 6
   Don't pay Fast Track unless you're up against a tender. Standard turnaround is up to 10 working days — plan around it.

Frequently Asked Questions

How much does CHAS accreditation cost per year?

There is no single price. CHAS uses dynamic pricing banded by employee count and by tier (Standard, Advanced, Elite), and the figure excludes VAT. CHAS's own blog cites CHAS Elite (Common Assessment Standard) starting at £539 per year for the smallest contractors (chas.co.uk); larger firms and higher tiers cost more. Always pull a live quote for your headcount before budgeting.

Is CHAS more expensive at renewal than in year one?

No — but it's not meaningfully cheaper either. The joining fee drops off in year two, but the annual assessment fee is broadly the same because you're being reassessed against the same (or an updated) module set. You'll also re-upload evidence whose certificates have expired in the interim.

Does CHAS accreditation cost include VAT?

No. CHAS states explicitly that its published prices exclude VAT (chas.co.uk/chas-standards). Add 20% to every figure. VAT is recoverable if you're VAT-registered.

What happens if I fail my CHAS assessment — is there a fee to resubmit?

Yes. According to the CHAS FAQ, if your application has been closed for less than 14 days you can pay a fee to reopen it — but only once. Further failures require you to buy a new application from scratch (chas.co.uk FAQ). This is why getting your health & safety policy and RAMS wording right first time matters commercially, not just administratively.

Is CHAS cheaper than SafeContractor or SMAS Worksafe?

It depends on your headcount and tier. CHAS scales with employees, so at small headcounts on CHAS Standard the gap to flat-rate SSIP providers can be small, but at larger headcounts on CHAS Elite it widens. Our CHAS vs SafeContractor vs Constructionline comparison and the cheapest SSIP scheme guide have the current picture. The right question isn't "which is cheapest" — it's "which one does my main contractor accept".

Do I need CHAS Elite or is CHAS Standard enough?

CHAS Standard demonstrates SSIP compliance and covers you where a client asks for "an SSIP scheme". CHAS Elite delivers the Common Assessment Standard, which is what public sector buyers should be asking for after PPN 03/24 and what large main contractors (HS2, Balfour Beatty, Costain and others) have said is their preferred prequalification (chas.co.uk). Buy the tier your clients ask for by name — not the one that looks cheapest on the slider.
