Comparisons
How Assured Contractors compares
Accreditation schemes such as SafeContractor, CHAS, Constructionline and Achilles assess a contractor's company. Site platforms such as HammerTech and MSite manage people at the gate. Assured Contractors is the client's own system from prequalification to the gate. The client pays one subscription and contractors connect free, so there's no Assured Contractors fee for them to recover in their prices. It isn't an SSIP scheme, so many clients keep requiring SSIP and store the certificate here.
Two categories
What kind of product is each one?
Buyers often put these side by side, but they do different jobs. Comparing like with like starts with knowing which is which.
Accreditation schemes
SafeContractor, CHAS, Constructionline, Achilles. An assessor reviews a company's health and safety (and sometimes wider) documents against SSIP, PAS 91 or the Common Assessment Standard and issues a certificate. The contractor usually pays an annual membership.
Answers: did this company meet a standard when it was assessed?
Site platforms
HammerTech, MSite. Software, often with gate hardware, that a main contractor uses to register and induct workers, control access, run permits and record what happens on site.
Answers: who is on site, and are they allowed to be?
Assured Contractors
The client's own system from prequalification to the gate: company documents, insurance and Companies House status, each worker's cards, vehicles, permits, bookings, gate check-in, visitors and muster on one record. The client pays; contractors connect free and keep one profile for every client.
Answers: is this company, and each of its people, ready for my site today — and why not?

Prices are the vendors' own “from” figures, checked November 2026; source numbers refer to the list above. Most of these pages don't say whether VAT is included, so check before comparing totals. Assured Contractors isn't an accreditation scheme, so it doesn't appear in this table and doesn't replace one: contractors connect to Assured Contractors free, on every plan, and the client pays one subscription. For SMAS Worksafe, Builder's Profile and what drives the cost, see UK contractor accreditation costs in 2026.

Questions
About these comparisons
Spotted something out of date? Tell us and we'll check and correct it.
Is Assured Contractors an SSIP accreditation scheme?
No. Assured Contractors doesn't assess companies or issue SSIP, PAS 91 or Common Assessment Standard certificates.
It's the system a client uses to run its own contractor assurance and its sites. Clients that require SSIP keep requiring it, and contractors store the certificate on their Assured Contractors profile with its expiry date.
Do contractors pay to use Assured Contractors?
No, on any plan. A client sends its contractors its company code or invite link; they join free in a couple of minutes and are connected straight away, then add each new client with that client's code. They keep one profile that every client they work for can see.
The client pays one subscription. Because contractors pay nothing, there's no Assured Contractors fee for them to recover in their prices. The schemes compared here publish what contractors pay for membership; we publish that contractors pay nothing.
Why compare Assured Contractors with both schemes and site platforms?
Because it sits between them. Schemes assess a contractor's company; site platforms manage people at the gate. Assured Contractors links the company record to each worker, their permits and bookings, and the gate — so buyers often look at both kinds of product when they look at us.
Where do the figures in these tables come from?
From each provider's own public web pages, linked in the numbered sources, checked November 2026. A dash means we couldn't find the capability published — not that the product can't do it. If something has changed, tell us and we'll correct it.
Can Assured Contractors and an accreditation scheme be used together?
Yes, and many clients do. The scheme certifies the company; Assured Contractors tracks the certificate's expiry alongside insurance, Companies House status, each worker's cards and everything that happens on site.
