About the IET Wiring Regulations

The IET co-publishes BS 7671 with the British Standards Institution (BSI) and is the authority on electrical installation. We run JPEL/64, (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. Find out more about how BS 7671 is developed.
