Approved Plumber Search

Find a local plumber you can trust using our free online directory search.

WaterSafe approved plumbers are certified by our national accreditation body, with specific training in the UK’s Water Fittings Regulations and Byelaws.

Hiring a WaterSafe approved plumber ensures that all plumbing work meets high standards and protects the quality of drinking water in your home and business, in England, Scotland, Wales, and Northern Ireland.

Water Support Services search

When planning a plumbing project, you may wish to hire specialised contractors, rather than a fully qualified WaterSafe Plumber.

These Water Support Services contractors include:

  • Groundworkers
  • Catering installers
  • Point of Use

These contractors are not approved WaterSafe plumbers, but they are recognised by the water company schemes APLUS, TAPS, WaterMark and WIAPS to carry out specific types of work in compliance with the Water Fittings Regulations and Byelaws. 


Groundworkers can work on the supply pipe (the underground pipe) supplying your property, up to the internal stop valve.

Catering installers

Catering Installers can install commercial kitchen equipment.

Point of Use installers

Point of Use Installers can install cold water chillers connected directly to the mains.

For further information or help, you should contact the relevant water company scheme.

Emergency Plumber Search

Find a local WaterSafe approved plumber to help with your emergency.

For leaks, burst pipes, or other plumbing emergencies, WaterSafe’s emergency search will give you the contact details of a plumber who can help right away.

If you have no water, very low pressure or concerns about the quality of your water, you should contact your local water company straight away.
