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.
