Suppliers

CHAS isn’t just for construction companies, it assesses health and safety for all types of suppliers, from care services to demolition contractors, designers and consultants. The aim of the scheme is to save time and resources by avoiding unnecessary duplication in the first stage of competence assessment; the CDM Core criteria.
