I need to remove a double socket in my kitchen permanently in order to tile over. Its previously been fitted with a blanking plate thus it was unused anyway. I would like an all flush tile finish without without anything protruding. The socket has two live, two neutral, and of course two earth running into it. I think there is another socket being fed from this one. Most of the wall has been tiled over and there is no loft space, the cables run in one of those flat conduit, been plastered and tiled over. What is the best way to to remove the soket within regulations.
