Probably.I guess that would be the electrician who's going to connect it all up.
But not if the whole thing comes as a surprise to him.
You can't do the former unless you've already agreed it with the person doing the latter.All I will be doing is the dirty work. Chasing walls, fitting back boxes and running and fixing cables. I will have someone in to fit a New cu and terminate all the sockets etc.
Which means you'll need definite proposals regarding responsibility for, and certification of, design, construction, inspection and testing which your LABC will have to approve.BC will be notified before I start.
