Meet buyer requirements
CHAS (SSIP) is requested by many main contractors and clients as a minimum for site access.
Accreditations
CHAS Accreditation Support
End-to-end help to achieve CHAS Standard, Advanced (PAS 91) or Elite (Common Assessment Standard) — without the admin headache.
Overview
What is CHAS?
CHAS (Contractors Health and Safety Assessment Scheme) is a recognised pre-qualification assessment. It helps contractors show clients they meet industry health & safety standards and — at higher levels — broader pre-qualification requirements.
Benefits
How CHAS will help your business
Win more work
Fewer PQQs and smoother onboarding—buyers recognise the assessment and tick you off faster.

Policies, RAMS and training records brought up to date, reducing risk and improving compliance.

FAQs
CHAS — common questions
Which CHAS level should I choose?
If your buyer only specifies SSIP, Standard is usually sufficient. For tenders that refer to PAS 91, choose Advanced. If buyers ask for the Common Assessment Standard or you want the most comprehensive coverage, go for Elite.
How long does it take to get accredited?
Our typical turnaround is 5–10 working days once evidence is gathered. We start prep immediately so nothing waits on you.
Can you help if we’ve failed an assessment?
Yes — we’ll review assessor feedback, plug evidence gaps (training/docs), and resubmit correctly with mapped references.
Do you provide the documents we need?
We supply an up-to-date policy & RAMS pack (editable), a training matrix, and evidence checklists tailored to your trade risks.
