Approved Contractor: FAQs

What is a certificate of compliance?

Also known as a work completed certificate this is a certificate issued by an approved contractor or sector scheme member to the person who engaged them to carry out plumbing work.

The approved contractor or sector member must issue a certificate of compliance to their customer. If the work was notifiable under regulation 5 of the water fittings regulations/byelaws, they must also provide the local water undertaker with a copy.

By signing the certificate, the approved contractor is certifying the work has been undertaken by them, or in the case of some schemes under their direction and is compliant with the water fitting regulations/byelaws.

A certificate of compliance can be used as a legal defence by a customer if the certified work is later identified as being non-compliant.
