We are CHAS

CHAS has been helping organisations in sectors like construction and the public sector stay safe and compliant for over 30 years. Founded by Merton Council, we quickly grew to serve the wider public sector, becoming the go-to partner for health and safety certification. As a founding member of SSIP and the first to offer the Common Assessment Standard (CAS), we know the ins and outs of safety compliance better than most.

With efficient, simple audits aligned with all major legislation (Procurement Act 2023, CDM Regulations, the Building Safety Act), CHAS contractors can confidently pre-qualify for valuable tenders and build business on certification they’re proud of.

For hiring clients, we make it easy to find the right contractors, with a network over 32,500-strong of certified, compliant professionals ready to get to work.

CHAS. We set the standard, so you can.
