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.

How do I protect against frozen pipes?

Cold weather can cause water to freeze. This is a problem because when water freezes in a pipe and turns to ice it expands. As the ice expands, it increases pressure on the pipes and joints, often causing them to split or joints to pull apart.

Check all pipes inside your home and any bare pipes outside your home are lagged and protected before the cold weather comes. Your local plumbing merchants and DIY stores can help you find the right insulation.

The Water Regulations Advisory Scheme has  an easy-to-use tool to work out how effective insulation will be in delaying the effects of cold weather on water pipes.

WaterSafe plumber Colin Stainer shows you how to quickly and easily insulate pipes in our video.

If you're not confident in doing it yourself, a qualified plumber will be able to help you. Use our postcode search to find a WaterSafe recognised plumber near you.

You can protect your pipes and fittings from freezing by:

  • Insulating all pipes in unheated areas like lofts, roofs, garages and outbuildings.
  • Fitting your water tank with an insulation jacket or alternatively the top and sides of the tank can be wrapped with suitable insulation material.
  • (Don’t place loft insulation under the tank though as this stops heat from the rooms below helping to keep the water in the tank from freezing).
  • Insulate toilet cisterns, water tanks or pipes in exposed places or unheated outbuildings. Better still, if not in use, drain them for the winter.
  • Leaving your heating on a low setting especially if your home is empty for a while.
  • Checking your central heating boiler has been serviced.
  • Finding your stop tap - so you can turn off the water supply quickly if a pipe freezes or bursts. Most are under the kitchen sink, or sometimes in a cupboard, garage or cellar.
  • Turning off your water supply and draining the system if you’re going to be away for a while – a WaterSafe recognised plumber will be able to give you advice.
  • Giving neighbours a key for your home and contact details for someone to help in an emergency if you go away.
  • Repairing leaks at taps or valves as soon as you discover them.
