If I Drill a hole directly through my wall for an outside light cable, and in the inside bury the cable in the plaster, do I need some kind of indicator on the inside that a cable is there? Like a back box with a blanking plate?
Trying to avoid running the cables around the exterior of the house, but realised if they were hidden in the plaster that would probably be naughty.
