On UK Business Forums, a contractor asks whether Constructionline is “really worth it”. One member, two years into paying for it, replies plainly: “Being registered with contructionline [sic] has not bought any business for the past 2 years.” And then: “So in relation to your question, I dont think it is worth it at all.” In a separate thread, a supplier’s experience runs the other way: “Its not for lead generation, but their customers insist they are registered on constructionline as its then pre-qualified – they won’t get the order unless they have it!”
Both are right. They are answering different questions.
We write construction bids every week at JGP, and this confusion costs contractors real money in both directions: firms paying for three overlapping badges they never needed, and firms skipping the one badge that would have kept them in a framework competition. So here is what these schemes actually are, what they cost, what buyers really ask for, and how to decide.
What you are actually buying
CHAS, Constructionline and SafeContractor sell two different things in one box.
The first is a health and safety assessment under SSIP, the Safety Schemes in Procurement umbrella, set up in 2009 with support from HSE. Pass any SSIP member scheme’s assessment and, in principle, every other member scheme should recognise it through what SSIP calls Deem to Satisfy. More on that “in principle” below.
The second is broader pre-qualification against the Common Assessment Standard (CAS), the industry questionnaire covering ten areas from financial standing to building safety. Build UK recognises seven bodies that can assess against it, including Constructionline, Veriforce CHAS, CQMS and SMAS Worksafe. SafeContractor is not on that list. This matters if your target buyers ask for CAS: a SafeContractor badge will not cover it.
Worth knowing before you treat the three as competitors: two of them are now one business. Alcumus, which has owned SafeContractor since 2015, merged into Veriforce in November 2024, and CHAS trades today as Veriforce CHAS, with the private equity firm Apax holding a controlling stake in the combined group. Constructionline has changed hands three times since it left government ownership in 2015.
What they cost, checked 13 August 2026
None of these prices sit still, and two of the schemes are vague about them, so treat these as entry points and check before you buy.
- CHAS: from about £410 to £430 for its Standard product depending which of its own pages you read (the products page says £429, the how-to-join page £409), rising to £909 for Elite, which includes CAS. Priced by headcount.
- Constructionline: no published price grid at all. Its own FAQ says membership “starts from as little as £399 a year”, with a one-off joining fee in year one based on turnover. Five tiers, from a free Associate listing to Platinum.
- SafeContractor: a published ladder from £540 (Standard) to £690 (Premier), plus an unpublished one-off joining fee.
- SMAS Worksafe, the cheaper SSIP route many contractors overlook: £345.
An annual spend of £1,500 or more across two or three schemes is easy to reach and very common. Whether it is wasted depends entirely on the next section.
What buyers actually require
This is where the marketing stops and the tender notices start. We went and read what public buyers are publishing on Find a Tender.
At the demanding end, the London Borough of Enfield’s £50 million highway maintenance contract (notice 2023/S 000-004411) states: “Applicants will be required to be a verified ‘Gold level’ member of Constructionline.” The word “equivalent” appears nowhere in the notice, and the council even hands out its own referral code for signing up to the scheme. Cambridgeshire County Council went further on a £15,000 electrical testing contract this January (notice 2026/S 000-003677): “Contractors submitting tenders will need to provide evidence that they possess CHAS accreditation (no alternatives acceptable).”
That Cambridgeshire wording is hard to square with the Procurement Act 2023, on two separate grounds. Section 22(4)(c) says conditions of participation may not “require particular qualifications without allowing for their equivalents”, and section 85 stops buyers restricting who may submit a tender for a regulated below-threshold contract based on an assessment of supplier suitability. No reported case has tested scheme-naming yet (we searched the National Archives case law service on 13 August 2026), so treat that as analysis rather than a ruling. But the direction of the law is clear.
Compare Staffordshire County Council and four partner authorities, whose frameworks ask for SSIP accreditation and Constructionline Gold membership but add: “where brand names are mentioned, the Authority will consider equivalents”, with evidence required from the successful supplier only before contract award. Same badges, opposite legal footing. And North East Lincolnshire Council’s capital works framework shows a third position, accepting firms part-way there: “Tenderers are required to demonstrate that they are a Constructionline Silver Member, who are working towards achieving Constructionline Gold Member status, and hold CHAS/SSIP.”
So the honest picture: named schemes appear constantly in real notices, sometimes lawfully with an equivalents route, sometimes without one. You can fight the bad ones with section 22 in a clarification question. You will still meet buyers who simply want the badge they asked for.
The mutual recognition problem
SSIP’s Deem to Satisfy is supposed to mean one health and safety assessment covers you everywhere. In practice, SSIP itself maintains a template “Model Letter to Buyers” for suppliers to send when a buyer refuses to recognise an existing SSIP assessment, and has re-issued it as recently as April 2026. A scheme owner that has to keep a standing letter asking buyers to honour its own recognition arrangement is telling you something: buyers often don’t. Deem to Satisfy binds the schemes to each other. It does not bind buyers, and any duty on a public buyer to accept an equivalent comes from the Procurement Act, not from SSIP.
So is it worth it?
Wrong question, or at least the wrong measurement. The contractor with two years of fees and no work was measuring his badge as a lead generator. Badges do not generate leads and never will. They are the tick boxes that get you through the gate, and their entire value is realised on the day a buyer’s questionnaire asks for one and you can say yes.
Our view, from the bids we write: get accredited, and where your target buyers straddle schemes, hold more than one. We usually advise clients to add accreditations, not shed them. But the badge is the entry ticket, nothing more. The firms that convert accreditation into contracts are the ones that build the systems the badge is checking for, because those same systems answer the quality and safety questions that actually get scored once you are through the gate. Buy the certificate and change nothing about how you operate, and you have bought a certificate.
How to decide, in an afternoon
Start from buyers, never from the schemes’ sales pages. List the five buyers you most want to work for over the next two years. Pull their last three tender notices from Find a Tender and read the participation conditions. Buy exactly what those notices name, at the level they name. If they straddle CHAS and Constructionline, hold both; entry prices for the pair start at about £830 a year before joining fees, against frameworks worth six or seven figures. If they consistently ask for CAS, make sure your scheme is one of the seven that can assess it. Then diarise your renewal date and repeat the exercise before paying again, because these requirements shift with framework cycles.
And before the next questionnaire lands, spend the money you saved on the thing behind the gate. If you want a second pair of eyes on where accreditations fit your bid pipeline, or on the PQQ and SQ answers they unlock, that is what we do all day. The Procurement Act changed the rules in bidders’ favour here; most firms just don’t use them yet.
