Some alterations have left us with a double socket where SWMBO does not want it (It was above a kitchen worktop - we have removed the worktop in that part of the kitchen.) The socket is on the ring - two cables to it. The box is a 35mm deep one and is also deep in the plaster. I seem to recall that if I want to plaster over it (plasterboard first) then I have to have the cables crimped - choc block not allowed.
Is this correct? Is there any way that I can legally join the cables and insulate them so that I can cover over the socket. I don't have access to a crimper.
