"BS 7671, although not a legal requirement, is a set of golden rules for electrical installation work and encourages best practice amongst the profession. The regulations are extensively referred to in health and safety documentation and, after 30 June 2008, all installations in the UK will have to comply with them."
- Geoff Cronshaw, Chief Engineer, Institution of Engineering and Technology
Ensure that your electrical installations conform to the latest safety guidelines from the British Standards Institution (BSI) and the Institution of Engineering and Technology (IET) as codified in BS 7671, Requirements for Electrical Installations. This is especially important as the Building Regulations Part P Electrical Safety now applies to all fixed electrical installations (for operation at low voltage or extra-low voltage) that are not controlled by the Electricity Supply Regulations 1988 or the Electricity at Work Regulations 1989.
BS7671 applies to the design, erection and verification of electrical installations, also additions and alterations to existing installations. Existing installations that have been installed in accordance with earlier editions of the Regulations may not comply with this edition in every respect. This does not necessarily mean that they are unsafe for continued use or require upgrading.
BS7671 includes changes necessary to maintain technical alignment with CENELEC harmonization documents.
BS 7671 Requirements for Electrical Installations is intended to come into effect on 1st July 2008. Installations designed after 30th June 2008 are to comply with BS 7671:2008.
