We now know for certain that a new amendment to the IEE Wiring Regulations is in the pipeline.
According to the IET the third amendment to BS 7671:2008 Requirements for Electrical Installations will be issued in January 2015 and is intended to come into effect on 1st July 2015. Installations designed after 30th June 2015 are to comply with BS 7671:2008 incorporating Amendment 3, 2015.
