Chas Accreditation

Over the years local authority health and safety and procurement professionals, with the support of the Health and Safety Executive, have developed the Contractor Health and Safety assessment scheme (CHAS). The scheme is available for use by any public and private sector organisations to use when short listing contractors, suppliers and consultants (companies) who apply to work for them. It provides information about the health and safety part of their application. Companies apply to join the scheme so everyone knows they meet acceptable standards of health and safety compliance. Clients from both the public and private sectors are users of the scheme and our database.
