Hi I am new to this forum and would appreciate any help. I am having a new kitchen fitted and need to move my cooker switch slightly to the left. I do not want the hassle of lifting floorboards to extend the cable and wondered if by routing the cable i already have slightly diagonally across the wall to the new switch position this would still be covered by part p regs. I know cable should not run diagonally but is this a part p requirement or just for safety when fixing anything to a wall at a later date?
