Regulation for rewring back box?

Former Community Member
Former Community Member

Hi, I'm currently holding an MEng in EEE, but not a certified electrician otherwise. 

I want to install smart light switches in my “dwelling”. I have encountered issues where the current back box is standard 74x74x25, but I would need extend it to 86x86x38 for the new light switch. 

I want check do I need part P certificate, or planning permission? How to be compliant while minimise the cost? (I have no experience in dwelling electrical work)

PS: The dwelling is a new build (2019) 
PPS: I might consider obtain required certificate(s) myself if is not too expensive. Since I like do these kind of work, so it might be cost effective in the long term.

    Another solution for very deep accessories is to get the wall replastered with nice thick plaster over the metal boxes.
