I​nstaller Overview

What is the difference between an approved contractor and member of a sector scheme?

An approved contractor is a qualified plumber belonging to an approved contractor scheme. They can certify all types of plumbing work in any premises as being compliant with the water fittings regulations/byelaws.

A sector scheme member is not recognised as being a plumber but rather someone who does limited specific plumbing work. Sector scheme members can only certify the plumbing within the scope of that sector scheme i.e. some but not all types of plumbing work.
