Cheapest SSIP Scheme in 2026: An Honest Price Comparison

If a main contractor has just asked for "an SSIP" and you're trying to pick the cheapest one before the deadline, this page is for you. We've pulled the published starting prices from every major SSIP member scheme, lined them up, and — more importantly — flagged the bit nobody on a sales call will tell you: the cheapest scheme today is only the cheapest if no client ever asks you for Constructionline Gold or the Common Assessment Standard later.

TL;DR — what's actually the cheapest SSIP scheme?

For a small subcontractor in 2026, the cheapest route to a stand-alone SSIP certificate is currently SMAS Worksafe, with the SSIP-only product starting at £317 a year for the smallest businesses (SMAS Worksafe quote page). The cheapest bundled route is Constructionline Bronze, from £219 a year, because every paid Constructionline membership now includes Once For All Health & Safety SSIP at no extra cost (Constructionline supplier FAQs). CHAS Standard and Alcumus SafeContractor are quote-based and tend to come in higher at the small-team end, but can be competitive at 10–50 employees. The catch every subbie should know: mutual recognition only ports the H&S core across schemes — not the wider PQQ modules — so if you'll also need Gold or the Common Assessment Standard, picking the cheapest H&S-only scheme first can mean paying twice.

What "SSIP" actually means (so we're comparing like with like)

Safety Schemes in Procurement (SSIP) is an umbrella body, not an assessment. It exists "to streamline prequalification and encourage straightforward mutual recognition between its Member Schemes" (SSIP.org.uk – About). When a main contractor asks for "an SSIP", they mean a current certificate from any of SSIP's registered member schemes — CHAS, SafeContractor, SMAS Worksafe, Constructionline's Once For All Health & Safety, Acclaim (now rebranded), and roughly thirty others.

All member schemes assess against the same SSIP Core Criteria, which is HSE-backed (SSIP – Suppliers). That's the whole point: the certificate is interchangeable for the H&S-core question set. So when we say "cheapest SSIP scheme", we're genuinely comparing equivalent outputs — a 12-month H&S certificate that any SSIP-accepting client should accept on its own merits.

How much does each SSIP scheme cost in 2026?

The table below is the headline starting price for each major SSIP member scheme at the smallest employee/turnover band, taken from each scheme's own website. Joining fees, fast-track add-ons and extra modules (CAS, environmental, quality) are not in these figures.

A few things worth calling out from that table:

• SMAS publishes its starting figure. SMAS Worksafe's quote page lists "Worksafe (SSIP) — from £317", with the wider Worksafe Plus (SSIP + PAS 91-style PQQ) from £523 and Worksafe Pro (the Common Assessment Standard) from £679 (SMAS Worksafe quote). A separate SMAS page lists the SSIP starting price as £345 (SMAS SSIP accreditation), so confirm the current figure when you ask for a quote.
• Constructionline Bronze is the only mainstream route where a paid PQQ membership and an SSIP certificate cost a single fee. Constructionline states explicitly: "SSIP is now included across our Bronze, Silver, Gold and Platinum memberships" (Constructionline sub-contractor memberships).
• CHAS and SafeContractor are quote-only at the entry level. That's not a criticism — both band by employee count and want to size you correctly — but it does mean you can't price-match without a phone call or form.

Which SSIP scheme is cheapest for a sole trader or 1–10 employee subcontractor?

For a sole trader or micro-business whose only goal is "get an SSIP certificate the main contractor will accept", the two cheapest published routes in 2026 are:

1. Constructionline Bronze at £219/yr (smallest turnover band), which throws in the Once For All Health & Safety SSIP certificate at no extra cost (Constructionline FAQs).
2. SMAS Worksafe SSIP at £317/yr at the smallest employee band (SMAS quote).

For a stand-alone SSIP without a PQQ database attached, SMAS is the lowest published number we found. For an SSIP plus a recognised buyer-facing PQQ profile, Constructionline Bronze is hard to beat on raw price.

Which is cheapest for a 10–50 employee subcontractor?

This is where the picture stops being obvious. Once you move past the smallest band, all five schemes raise their fees, and the gap between them narrows. At this size:

• CHAS and SafeContractor become more competitive because their pricing scales by headcount, and at the small-to-mid band they often quote in a similar range to SMAS. Neither publishes a public price list — you'll need to request a quote from CHAS and SafeContractor to compare like-for-like.
• Constructionline Bronze stays a strong bundled play, but its annual fee scales by turnover, so a higher-turnover firm with few staff can find it overtakes SMAS.
• SMAS stays predictable and publicly priced.

If you have ten minutes, the honest answer for a 10–50 employee firm is: get a written quote from CHAS, SafeContractor and SMAS, plus a Constructionline Bronze price for your turnover band, and pick the cheapest that has a UK contractor's name your clients recognise. That sounds like fence-sitting; in our experience it's the only way not to overpay, because all four bands move in 2026.

The hidden cost: mutual recognition only covers the H&S core

This is the bit that turns "cheapest today" into "most expensive over three years". SSIP's Deem to Satisfy (DtS) mechanism lets you take an existing SSIP certificate to a second member scheme and get its certificate at a reduced fee, without going through the full assessment again. The SSIP forum is explicit that DtS gives you "mutual recognition by ALL other SSIP Registered Member schemes" (SSIP Forum).

What DtS does not port across is the wider PQQ. So:

• If you buy SMAS Worksafe SSIP at £317, and then a main contractor demands Constructionline Gold, you'll get a discounted DtS rate for the H&S portion — but you'll still need to upload your finance, insurance, equal opportunities, modern slavery, environmental and quality evidence into Constructionline.
• If you then add the Common Assessment Standard (asked for by HS2, Balfour Beatty, Bouygues UK, Costain and Derwent London, per CHAS), you'll re-upload most of the same evidence again in the CAS-format question set.

The certificate gets recognised. The evidence does not.

When is the cheapest SSIP scheme not the right SSIP scheme?

Three cases where the price-list answer is the wrong answer:

1. The main contractor has a named preferred scheme. Many do. If they ask specifically for CHAS or SafeContractor, mutual recognition theoretically helps — but in practice some buyers want the named scheme's logo on the certificate. Ask before you pay.
2. You will need the Common Assessment Standard within 12 months. If you're tendering on public-sector work covered by PPN 03/24, you'll eventually need CHAS Elite, Constructionline Gold or an equivalent CAS-assessed product. Starting on a cheap stand-alone SSIP and then bolting on CAS separately costs more than picking a scheme whose upgrade path goes straight there.
3. Your clients use Constructionline's buyer portal. If your main contractors actively search Constructionline for suppliers, being listed on it has real commercial value beyond the certificate. That can tilt the choice towards Constructionline Bronze even if it isn't the absolute lowest sticker price.

Cheapest SSIP scheme by use case

What to ask any SSIP provider before paying

1. 1
   Get the all-in number, not the headline. Ask for the total of: annual fee at your band, joining/setup fee, fast-track surcharge if used, and any VAT. Schemes publish the first; they often don't lead with the rest.
2. 2
   Confirm what's actually on the certificate. Some products are SSIP-only; others bundle environmental, quality, modern slavery or PAS 91-style PQQ. You may not need any of those — don't pay for them by accident.
3. 3
   Ask what happens at renewal. Most SSIP certificates are valid 12 months. Confirm the renewal price, not just year-one pricing, and whether the joining fee is one-off (it usually is).
4. 4
   Check Deem to Satisfy fees in both directions. If your main contractor might switch you to another scheme later, what does it cost to port your certificate into and out of this one? It's usually a fraction of full price, but not free.
5. 5
   Diary the expiry date the day you're certified. SSIP certificates lapse at 12 months and the system will not chase you the way insurers do. A missed renewal is almost always more expensive than the cheapest scheme.

We're building TradeComply partly to solve that last step — tracking your renewal dates and the evidence you've already uploaded so you don't re-do the same work across schemes. It's not live yet; the waitlist is here if that matters to you.

Frequently Asked Questions

Which SSIP scheme is cheapest for a sole trader or micro business?

The cheapest stand-alone SSIP certificate for a sole trader is SMAS Worksafe SSIP at £317 per year for the smallest employee band. If you also want a buyer-facing PQQ profile, Constructionline Bronze at £219 per year is cheaper because it bundles the Once For All Health & Safety SSIP certificate at no extra cost. Both certificates are fully recognised under SSIP mutual recognition.

Does the cheapest SSIP scheme cover everything I need?

The cheapest schemes cover the SSIP Core Criteria for health and safety only, which is enough to satisfy "an SSIP" request from most main contractors. They do not include the wider PQQ modules (finance, insurance, environmental, quality, modern slavery) required for Constructionline Gold or the Common Assessment Standard. If you'll need those later, starting on a cheap H&S-only scheme can mean paying again to upgrade or switch.

Can I switch SSIP schemes if a client asks for a different one?

Yes, under Deem to Satisfy (DtS) you can port an in-date SSIP certificate from one member scheme to another for a reduced fee, without a full re-assessment of the health and safety questions. The SSIP certificate itself transfers; the wider PQQ evidence you uploaded to the first scheme does not, so you'll re-upload finance, insurance and other modules if the new scheme asks for them.

Do SSIP schemes charge renewal fees every year?

Yes, all SSIP certificates are valid for 12 months and require annual renewal at the published annual fee. Most schemes charge a one-off joining or setup fee in year one, which does not recur at renewal. You'll need to re-submit updated evidence (insurance certificates, risk assessments, training records) each year to keep the certificate current.

What's not included in the base SSIP price?

The base SSIP price covers health and safety assessment only. It does not include: joining or setup fees (often charged separately in year one), fast-track or express-service surcharges, environmental modules, quality accreditation (ISO 9001 or equivalent), the Common Assessment Standard, or Constructionline Gold/Silver/Platinum upgrades. Always ask for the all-in total including any one-off fees before comparing schemes.
