BS 7671

Ensure that your work meets the requirements of the Electricity at Work Regulations 1989.

BS 7671 (IET Wiring Regulations) sets the standards for electrical installation in the UK and many other countries. The IET co-publishes BS 7671 with the British Standards Institution (BSI) and is the authority on electrical installation.

About BS 7671

The IET runs the JPEL/64 committee, (the national Wiring Regulations committee), with representatives from a wide range of industry organisations. The committee takes on board information from international committees and UK specific requirements, to ensure consistency and improve safety throughout the UK electrical industry.

The 18th Edition IET Wiring Regulations (BS 7671:2018) published in July 2018. All new electrical installations will need to comply with BS 7671:2018 from 1st January 2019.

In April 2019, a webinar was held to address some of the questions that industry have around the 18th Edition.  A full list of Q&As from this webinar is available here.
