Scroll to the footer of most construction or fit-out contractor websites and you’ll see a row of logos — CHAS, SSIP, Constructionline, NICEIC, and similar. Most site visitors scroll straight past them. That’s a missed opportunity, because these badges aren’t decoration — each one represents a genuine, independently verified assessment that tells you something real about the contractor you’re considering. Here’s what each one actually checks, and why it should matter to your decision.
CHAS — Contractors Health and Safety Assessment Scheme
CHAS is one of the UK’s longest-established health and safety accreditation schemes. To hold it, a contractor submits detailed evidence of its health and safety policies, risk assessment processes, and management systems, which is then independently assessed against recognised standards — not simply declared by the contractor itself.
What it actually tells you: the contractor has a properly documented, independently reviewed approach to managing health and safety risk on site — not just a policy document sitting unused in a folder.
SSIP — Safety Schemes in Procurement
SSIP isn’t a single certification body — it’s a recognised umbrella standard that a range of accreditation schemes (including CHAS) operate under. The point of SSIP is to create a consistent core standard across different assessment bodies, so a client evaluating contractors doesn’t need to interpret several different schemes independently.
What it actually tells you: the contractor’s health and safety credentials meet a nationally recognised baseline that public sector frameworks and many private clients accept as proof of competence, reducing the due diligence work a client would otherwise have to do themselves.
Constructionline Gold
Constructionline is a supply chain pre-qualification and accreditation service widely used across UK construction procurement. The “Gold” tier sits above the standard membership level and requires evidence covering financial standing, health and safety management, environmental management, equality and diversity policies, and quality management — a considerably broader assessment than health and safety alone.
What it actually tells you: the contractor has passed a multi-dimensional pre-qualification check, not just a safety-specific one. This is often used as a shortcut through the pre-qualification stage of public sector tenders, precisely because it already covers what a buyer would otherwise need to verify manually.
NICEIC
NICEIC is the leading certification body for electrical contractors in the UK. Registration requires an assessed inspection of a contractor’s electrical work, technical competence, and compliance with BS 7671 (the IET Wiring Regulations), along with ongoing periodic reassessment to remain certified — it isn’t a one-off badge earned once and kept indefinitely regardless of standards slipping.
What it actually tells you: any electrical work carried out is done by assessed, competent electricians working to the recognised national wiring standard — directly relevant on almost any refurbishment or fit-out project involving mechanical and electrical (M&E) work.
Why This Matters More Than It Might Seem
It’s easy to treat accreditation logos as background noise on a contractor’s website. But each one exists specifically because self-declared competence isn’t something a client should have to take on trust — these are independent verifications, assessed by a third party against a defined standard, with periodic reassessment required to keep them current.
This is particularly relevant for public sector procurement, where accreditations like these are often a formal requirement rather than a nice-to-have, and for any project where choosing the right commercial refurbishment contractor depends on being able to verify competence before committing budget and programme to them.
What We Hold, and Why
At Mobius Group, we hold CHAS, SSIP, Constructionline Gold, and NICEIC accreditation, alongside ISO 9001 certification and a Social Value credential. But as we’ve said elsewhere, accreditation on its own isn’t the differentiator — what actually matters is how those independently verified standards are applied on every project, not just referenced on a website footer.
If you’re evaluating contractors for an upcoming project, ask to see current certificates rather than taking accreditation claims at face value — any genuinely accredited contractor will provide them without hesitation.
