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.
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:
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 can install commercial kitchen equipment.
Point of Use Installers can install cold water chillers connected directly to the mains.

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.
Water pressure within the home can vary based upon the location, type and height of the property, as well as the type of appliances used and how much water is being used by other customers.
Water pressure can vary at different times of the day. Pressure is normally higher late at night when very little water is being taken from the mains network and most people's taps are turned off. In the morning when people are taking a bath or shower, or watering their garden on a hot evening, there is a bigger demand for water which can cause low pressure.
Water suppliers’ statutory service standard level of mains water pressure is 10 metres/head (or one bar). This means there is enough force/pressure to push the water to a height of 10m.
This is measured at the point where the water leaves the water suppliers’ pipework and enters yours (usually the outside stop valve or property boundary).
As a guide, if you have a suitable single service pipe, the first tap in the home (this is usually the kitchen tap) should be able to fill a 4.5 litre (one gallon) bucket in 30 seconds, with all other taps and appliances turned off. Another way of putting it is enough water pressure to fill a cold water storage cistern in a two storey house roofspace.
It is possible to make changes to your internal plumbing to improve your water flow. For example by ensuring your stop tap is fully open. You could also check that any systems that depend on the supply pressure are set to the statutory minimum level of 1 bar/10 metres head.
