Approved contractor schemes

There are currently seven Approved Contractors Schemes in the UK. 

Four are approved by the water undertaker for the area which they supply.

Three are certified by the Regulator 

All the schemes have the same entry requirements:

  • A recognised qualification in plumbing
  • A recognised qualification in Water Fittings Regulations or Scottish Water Byelaws 
  • An appropriate level of public liability insurance and employers’ liability cover.

Each Approved Contractor Scheme operates in different geographical area. To join a scheme a plumber or plumbing business must reside or be located in the geographical area covered by that scheme.
