CHAS: The Contractors Health and Safety Assessment Scheme
CHAS accreditation ensures all suppliers show compliance with important parts of health and safety law (the core criteria described in the CDM regulations).
CHAS accreditation ensures inconsistencies are reduced where some suppliers may be judged compliant by one buyer but not another.
CHAS gives guidance on any weaknesses in a supplier's safety management, including how they can improve.
CSCS: Construction Skills Certification Scheme
CSCS is the leading skills certification scheme within the UK construction industry.
CSCS cards provide proof that individuals working on construction sites have the required training and qualifications for the type of work they carry out.
The Scheme keeps a database of people working in construction who have achieved, or are committed to achieving a recognised construction related qualification.
Most principal contractors and major house builders require construction workers on their sites to hold a valid CSCS card.
