There are many books on the market which attempt to explain the regulations; most look as complex as the regulations themselves. This book explains the regulations as opposed to simply repeating them. The tone of this book is conversational and it is an easy read.
The book takes a look at the regulations step by step and tells you what to do in order to comply with them. In brief it tells you all those things a decent regulations lesson would explain. If you liked Chris' previous book Practical Guide to Inspection, Testing and Certification of Electrical Installations: Conforms to 17th Edition IEE Wiring Regulations (BS 7671:2008) and Part P of Building Regulations
you will like this one too.
I know Chris personally and am proud to endorse this book.
