BS 7671 Requirements for Electrical Installations
The British Standards Institution (BSI) publishes standards and provides a range of books, self-assessment tools, conferences and training services. It also represents UK economic and social interests in European and international standards organisations.
BS 7671 Requirements for Electrical Installations (the wiring regulations also known as the brown book) sets the standards for electrical installations in the UK. It is published by BSI and the Institution of Engineering and Technology (IET). Technical authority for this Standard is vested in the Joint IET/BSI Technical Committee JPEL/64. This Joint Technical Committee, which is responsible for the work previously undertaken by the IEE Wiring Regulations Committee and the BSI Technical Committee PEL/64, meets the constitutional and operational requirements of both parent bodies. JPEL/64 has the responsibility for the content of this British Standard under the joint authority of the IET and the BSI Standards Board.
Following a full review, the 18th edition (BS 7671:2018) replaced the 17th Edition of the IEE Wiring Regulations BS 7671:2008 as amended.
It is available at: https://electrical.theiet.org/bs-7671/
Amendment 3 to BS 7671:2018 was published by the Institution of Engineering and Technology in agreement with BSI on 31st July 2024 and is intended to be implemented immediately.
This Amendment provides for the inclusion of two new definitions and one new Regulation relating to the use of bidirectional and unidirectional devices.
Amendment 3 can be downloaded at: https://electrical.theiet.org/bs-7671/updates-to-18th-edition/
NB On August 6 2024, ECA announced a consultation for Ammendment 4 to the regulations. The greatly anticipated amendment will incorporate changes to harmonised standards at European level which the UK has to adopt within a certain time period.
