BS 7671

With SBE Electrical & Security all electrical work will be designed, constructed, inspected, tested and certified in accordance with BS 7671 (as amended)


British Standard BS 7671 “Requirements for electrical installations” is the national standard in the United Kingdom for low voltage electrical installations.

It is also used as a national standard by Mauritius, St Lucia, Saint Vincent and the Grenadines, Sierra Leone, Sri Lanka, Trinidad and Tobago, Uganda, Cyprus , and several other countries base their wiring regulations on BS 7671.

The IET (formerly IEE) has published wiring regulations in the United Kingdom since 1882. Since their 15th edition (1981), these regulations have closely followed the corresponding international standard IEC 60364. Today, they are largely based on the European Committee for Electrotechnical Standardization (CENELEC) harmonization documents, and therefore are technically very similar to the current wiring regulations of other European countries.

In 1992, the IEE Wiring Regulations became British Standard BS 7671 and they are now treated similar to other British Standards. They are maintained by the Joint IET/BSI Technical Committee JPEL/64, the UK National Committee for Wiring Regulations. Although the IET and BSI are non-governmental organizations and the Wiring Regulations are non-statutory, they are referenced in several UK statutory instruments.
