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 know if I have a leak in or around my home or business?

How to check for a leak at your property

Common sources of leaks in the home include toilets, dripping taps, showers, radiators and pipework.

Also look out for poorly plumbed appliances and overflows from a water tank or cistern in the loft. Check outside taps too.

Some leaks are hidden from view and easy to miss. If you're on a meter, a higher than normal bill may mean that there is a leak on one of your pipes or appliances.

Not sure where your meter is?

  • Inside: it’s normally fitted close to your internal stop tap, which in many homes is under the kitchen sink, in the downstairs loo, on in your garage.
  • Outside: usually near the boundary of your home, such as in the front garden, your drive or in the footpath. You may need a screwdriver to lift the outer lid.

You can also sometimes find it in a wall-mounted box on the side of your home.

Now you can check your meter in a few simple steps:

  1. Turn off all the taps and appliancesin the house that use water.
  2. Wait 30 minutes to allow any tanks and cisterns to fill up, then write down your current meter reading (including the red digits).
  3. Take a second reading after at least two hours, or overnight, making sure no water has been used in the meantime.
  4. Check the meter reading again, especially the red digits. If the reading is higher, this means there could be a leak in your home.

If you're not on a meter, signs of a leak could be:

  • Loss of pressure
  • Rust
  • Areas of lush vegetation – could be a symptom of a recent leak during dry periods
  • Areas of reduced vegetation – this could be a symptom of a long term leak
  • Damp patches on walls, floors or carpets
  • Mould on ceilings and walls
  • A constant noise of flowing water coming from the pipes in your home.

If you have a leak on your supply pipe outside your home, check with your water supplier as they may be able to help repair it. If you think you have a leak inside your property you'll need to contact a plumber. You can use our postcode search to find a WaterSafe recognised plumber near you.
