Got a query for you. I want to move my 45A Cooker. I have been told i cant just junction box it and run it around in the wall. Gotta have an unjoined cable. Now heres the trouble. I don't wanna chase out walls, can I run in a new cable and run it on the surface of the walls, and just put it in White plastic mini trunking, so long as I take it back to the Consumer Unit?
