That has to be done before you start, and they have to agree with you doing the work and the electrician checking it afterwards.Yes building control will be notified
How would they know who done the work, so long as it's done correctly?
I'm doubt they will want to.I don't think Building control need to inspect if he's registered as being competent.
Not reallyI must say, what a minefield BC and regs are
For someone who doesn't deal with BC, and is unsure what is notifiable, what isn't, what you can get away with and what you can't? what you need certificates for, and what you don't. It is. when is a kitchen ceiling a fire guard? etc. Just seem to get conflicting views. And "you need a plumber, you need a spark for that" when you don't. How do these people on the TV who renovate houses seem to do what they want, but the likes of me have to jump through hoops?.
