IET & BSI publish Corrigendum to BS 7671:2018 (IET Wiring Regulations)

The Institution of Engineering and Technology (IET) and British Standards Institution (BSI), announce the release of a Corrigendum to BS 7671:2018+A2:2022. The Corrigendum makes changes to five areas of the IET Wiring Regulations and will come into effect immediately upon its publication on Monday, 15 May 2023. The Corrigendum will be available for free download from the IET and BSI.

The changes include:

  • Regulation 422.2 has been amended to clarify the scope of the provision.
  • Indent (ii) of Regulation 443.4.1 has been removed. The term safety service, formerly included in Regulation 443.4.1 (ii), encompassed a wide range of systems. The provision, therefore, had unintended consequences for improvements to fire safety systems within installations.
  • Table 443.2 and the Note to Regulation 534.4.1.1 have been amended to remove examples of equipment.
  • Regulation 701.1 has been amended to remove the reference to birthing pools.
  • A new Regulation, 710.422.2.201, has been included in order to modify requirements in Regulation group 422.2 for protected escape routes in healthcare facilities.
