Consultation on water undertakers' Regulation 4(1)(a) guidance documents

The Water Supply (Water Fittings) Regulations 1999, the Water Supply (Water Fittings) (Scotland) Byelaws 2014 and the Water Supply (Water Fittings) Regulations (Northern Ireland) 2009 impose a legal duty not to install water fittings unless they satisfy the requirements specified in Regulation/Byelaw 4. That is to say are of an appropriate quality and standard; suitable for the circumstances in which they are used; and compliant with any applicable requirements specified in Schedule 2.

Water undertakers have the statutory duty to enforce the Regulations/Byelaws. To facilitate compliance water undertakers have developed guidance which:

  • describes the acceptance principles adopted by water undertakers when enforcing the requirements of Regulation/Byelaw 4(1)(a).
  • identifies the information water undertakers may consider as evidence of compliance with those aspects of the regulations relating to the quality and standard of water fittings; that is to say Regulation/Byelaw 4(1)(a).
