Introduction to BS 7671:2008
BS 7671:2008 (2011) Requirements for Electrical Installations was issued on 1st January 2008 and is intended to come into effect on 1st July 2008. Installations designed after 30th June 2008 are to comply with BS 7671:2008 Incorporating Amendment 1: 2011.
The Regulations apply 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. BS 7671:2008(2011) includes changes necessary to maintain technical alignment with CENELEC harmonization documents.

BS 7671 (The IET Wiring Regulations) are the national standard to which all domestic and industrial wiring must conform. The 17th edition contains substantial changes to align with European documents. The IEE Wiring Regulations are produced by the Institution of Engineering and Technology (The IET). The IET is an imprint of the Institution of Engineering and Technology and is used for all books related to the Wiring Regulations.
