Wiring Regulations BS7671

18th edition with blue cover, published in July 2018 and applicable from 1 January 2019.

This video and the text below cover the main changes in Part 6 - Inspection and Testing.

The main change in Part 6 is that the entire content in chapters 61, 62 and 63 has been removed. Two new chapters have been added, with 64 containing content previously in 61, and 65 being the equivalent of the old 62. Content previously in Chapter 63 has been divided and added to the end of both 64 and 65.

While much of the content is unchanged other than it's location within the chapters, there are various smaller changes and these are described in the video and the text section below.
