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.

Do I need to notify my water supply company of planned plumbing work?

Possibly. Some types of plumbing work are covered by laws called the Water Supply (Water Fittings) Regulations or Byelaws in Scotland and so do require permission to be granted by your local water supply company before they can begin.

Types of plumbing work that must be notified to water suppliers include:

  • Building a house or other property/structure
  • Extending or altering the water system on a non-household building
  • Changing the use of a building or installing water systems, such as rainwater harvesting
  • Installing a swimming pool or pond over 10,000 litres
  • A garden watering system (unless operated by hand)
  • A bath which holds more than 230 litres of water
  • A bidet with an upward spray or flexible hose
  • A pump or booster that delivers more than 12 litres of water per minute
  • A reverse osmosis unit (for cleaning water)
  • A water treatment unit which produces waste water
  • A reduced pressure zone (RPZ) valve assembly or similar
  • Any water system outside a building that is either less than 750mm (0.75 metres) or more than 1350mm (1.35 metres) below ground.

In Northern Ireland and Scotland, notification is also required for:

  • Grey water, recycled water, reclaimed water and rainwater harvesting
  • Water systems for firefighting, including domestic sprinklers
  • A flexible shower hose or other flexible outlet for use with a WC
  • A ‘shower toilet’ or ‘bidet-toilet’ either as part of the WC itself or where as an addition or adaptation of it, a stream of water is provided from below the spillover level of the WC pan for personal cleansing.

In Scotland, there is an additional requirement for notification of any system incorporating a private water supply.

Not everyone is aware of the regulations, but WaterSafe approved plumbing businesses are. They are in place to ensure the plumbing meets the Water Fittings Regulations and Byelaws which are designed to keep drinking water supplies safe and healthy.

If you are unsure, consult your local water supply company.
