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.

The Winter Blues

Watersafe Plumber Colin Stainer on the importance of protecting your water pipes this winter.

"As a plumbing and heating engineer I have seen many disasters over the years – freezing houses, burst pipes and extensive damage.

I remember being woken up in the early hours of one morning, about 3am, by my phone repeatedly ringing. I answered it to hear a lady in a frantic state - she was talking so fast that I couldn’t understand her. Still half asleep I told her to stop, take a few deep breaths and not to panic.  She told me she lived on her own and had been in her bathroom washing her hands when the tap broke and she couldn’t stop the water running.  She had tried to ring all the 24-hour emergency plumbers, but no-one was answering.

I told her to fill a kettle and a large pan with water, then to have a look under the kitchen sink to see if there was a valve. Hey presto, there was. I instructed her to turn it clockwise and, guess what, the water stopped! Her voice changed and I could hear the relief. At a slightly more reasonable hour I went to her house and she made me a cup of tea while I repaired her tap.

Anyway, the moral of the story – make sure you know where to turn off your water, and most importantly, keep calm and do not panic!

Knowing where to turn your water off can be vital in winter. Water pipes can freeze and burst and waste pipes can freeze and cause basins to overflow if taps are dripping or running – all leading to floods and winter blues if you don’t know how to turn your water off quickly.

The last couple of winters have been quite mild, but if we do get a cold winter with temperatures dropping to minus 10C it pays to be prepared.

My top points are:

  1. Make sure you know where your stop tap is and check it is working
  2. If you are going away, leave your central heating on as normal and put the room thermostat at 14C
  3. Make sure all roof and vulnerable pipes are insulated and your boiler is serviced
  4. Make sure you have the name and telephone number of your WaterSafe qualified plumber to hand. Keep it by the boiler or stop tap!
  5. Get a neighbour to look in occasionally if you go away.

One of the most common problems these days is outside garden hose taps freezing.  In the winter, turn off the inside tap that controls the garden tap, open the outside tap and leave it open until Spring is with us. Repairing these is now one of our most common winter call-outs.

In the past I have seen houses freeze and pipes burst, especially in roof spaces and garages, causing extreme damage, especially when it is very windy. The wind can blow into roofs and drop the temperature very rapidly. So make sure you are ready!  

The good thing now is that we have better insulated houses with double glazing and most modern boilers have frost protection built in, so if the temperature drops to 5C the boiler will turn itself on for a few minutes to stop it freezing.  Ask your heating engineer if your boiler has built-in frost protection when you have your next service. 

But if the worst happens and you do get a burst pipe or leak, then remember my 3am lady – and DO NOT PANIC. Fill the kettle and a pan or bucket with water before turning off the stop tap and also remember to turn off your boiler and immersion heater if the central heating pipes have frozen. Then open all your taps, hot and cold to take off the pressure.  Most importantly, KEEP CALM and call your plumber."
