IET and BSI call on electrical industry to have say on Amendment 2 of BS 7671:2018 (18th Edition IET Wiring Regulations)

BS 7671:2018+A2:2022, expected to publish in spring 2022, will be the first, full, consolidated Amendment to the 18th Edition IET Wiring Regulations, which published in 2018.  It will also include Amendment 1:2020, which published as a standalone PDF in February.

What are the proposed changes?

One of the largest proposed changes in Amendment 2 is a new Part 8 – Functional Requirements.  This includes Chapter 82: Prosumer’s Low-Voltage Electrical Installations.  A prosumer is both a producer and consumer of electricity.  This new chapter sets out the requirements for Prosumer Electrical Installations (PEIs), including considerations for interaction with the smart grid, safety requirements (including earthing arrangements), proper functioning and implementation.  Electrical installers will have a large part to play in the selection of the most appropriate equipment and a comprehensive knowledge of this area will be key as prosumer technologies develop.

Important changes to fire safety requirements are proposed in Chapter 4, covering the design of electrical installations in industrial, commercial and multiple-occupancy homes, as well as new information for ‘protected escape routes’.

Additional changes are also proposed to the following areas:

  • Regulation 421.1.7 – further information on the use of Arc Fault Detection Devices (AFDDs)
  • Regulation 443.4 – further information on Overvoltages
  • A new Normative Annex (542) on Earthing Arrangements
  • Multiple changes within Section 7: Special Locations

This is not an exhaustive list, and many other changes are proposed throughout the Regulations.  An overview of all of the changes proposed is included in the ‘Introduction to Amendment 2’ at the beginning of the DPC document.

Mark Coles, Head of Technical Regulations at the IET, says of Amendment 2: “This Amendment is the result of years of work by the JPEL/64 committee, the committee responsible for BS 7671, taking on board requirements from international and European standards, as well as input from organisations such as the Health & Safety Executive (HSE) and the findings of the Independent Review of Building Regulations and Fire Safety (2018).

“It is vital that the electrical installation industry keeps up to date with the constant developments in technologies that impact our work, improving the efficiency of installations and enhancing sustainable development.  Above all, we must ensure that safety remains of paramount importance, and this is reflected in the proposed changes to BS 7671:2018.”

Dan Palmer, Associate Director of Committees at BSI said: “In our role as the UK National Standards Body, BSI has published the draft standard, called BS 7671 Requirements for Electrical Installations. IET Wiring Regulations, for public comment. We welcome industry experts to review the newly amended standard and share best practice and learnings from their experience. The standard will be published with consensus amongst stakeholders.”

The Draft and information on submitting your comments are available on the BSI website from 21 September 2020.  You can find more information and links to the content at theiet.org/updates.  Please ensure you submit your feedback by the deadline of 11 December in order for it to be accepted for discussion.
