The Water Fittings Regulations (or Byelaws in Scotland) are national requirements for the design, installation 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 or the contamination of drinking water.  They apply to a very wide variety of systems in all types of premises and govern all systems from after the point where water enters the property’s underground service pipe.

Owners and occupiers of premises and anyone who installs plumbing systems or water fittings have the legal duty to ensure that the systems satisfy the regulations. In many cases advanced notice must be given for proposed installations so it is common for architects, building developers and plumbers to have to follow the regulations on behalf of future owners or occupiers.

Plumbing systems must be designed, installed and maintained to meet the regulations’ requirements and materials and fittings must be of a suitable standard. It is illegal to install fittings that do not meet the standards. Guidance on the standards and information on materials and fittings meeting these standards can be found on the Water Regulations Advisory Scheme (WRAS) website
