CHAS is one of the UK's leading pre-qualification schemes for contractor health and safety. Holding a current CHAS Premium / Premium Plus / Elite assessment means the company's H&S management has been audited against SSIP (Safety Schemes in Procurement) Core Criteria — risk assessments, training records, accident reporting, RAMS workflows, and director-level H&S accountability. CHAS is widely recognised by Tier 1 construction firms and public-sector buyers as a baseline pre-qualification, often saving the buyer the work of running their own bespoke H&S vetting.
Issued by
CHAS Ltd, an SSIP-registered assessment scheme.
Why it matters
On any construction or industrial site, the principal contractor or property owner is responsible for the H&S of everyone on site — including the security team. A current CHAS certificate (or Constructionline equivalent) means you don't need to run your own due diligence on the security provider's H&S records.
Questions to ask a provider
- What level of CHAS do you hold (Premium / Premium Plus / Elite)?
- When does your current certificate expire?
- Can you provide your CHAS reference for our principal contractor's portal?
