Effective 6 April 2013. This edition reduces the range of electrical installation work that is notifiable. In addition, installers who are not registered competent persons can now use a competent person to certify work as an alternative to using building control. The technical guidance throughout now refers to BS7671:2008 incorporating Amendment No 1:2011. This Approved Document has a fresh new look and has been totally re-designed into a single column format to make reading. It has also been subject to a thorough editorial review to make the text/content more reader-friendly and simpler to assimilate and understand.
