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.

You can also find tips and advice in our short films on  WaterSafe’s YouTube channel.

What are the Water Fittings Regulations and Scottish Water Byelaws?

The Water Fittings Regulations and Scottish Water Byelaws are national requirements for the design, installation, operation and maintenance of plumbing systems, water fittings and water-using appliances. Their purpose is to prevent misuse, waste, undue consumption or erroneous measurement of water and, most importantly, to prevent contamination of drinking water. They replaced the former local Water Supply Byelaws, which each water supplier administered for similar purposes for many years and are designed to protect public health and promote the efficient use of water.

What do the Water Fittings Regulations and Byelaws apply to?

The Water Fittings Regulations and Scottish Water Byelaws apply to all plumbing systems, water fittings and water-using appliances supplied, or to be supplied, from the public water supply. They apply to systems in all types of premises. These regulations apply from the point where water enters the property’s underground pipe. They do not apply to premises without a public water supply connection.

Where can I get a copy of the regulations and further advice?
