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

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.

Why is my water discoloured?

On rare occasions tap water may become discoloured, appear cloudy, or appear to have very small particles in it.

Discolouration can range from a light straw yellow colour to dark brown. It can be caused by a number of things including:

  • Naturally occurring substances
  • Disturbance of mains deposits
  • Corrosion of service pipes
  • Internal plumbing issues.

In most cases discoloured water is not harmful and can be cleared by running the first incoming cold water tap (usually in the kitchen) at a trickle until it clears.

Very occasionally water suppliers receive calls about "tiny particles" or "bits" in their tap water. This can be caused by:

  • Planned or unplanned work to the water supply network which causes sediment in the pipes to shift (quite often this is a dark red, brown colour)
  • Small dark grey or black particles can occasionally be caused if your pipework is made from lead. This is most likely if your house was built before 1970.

For more information, please contact your  water supplier.

Please note: If your water is blue, pink, green or any other colour not described above, please do not drink the water or use it for cooking purposes until you have sought advice from your water supplier.
