Thanks to all for the responses, in the end I removed a strip of plasterboard as suggested, ran and fished the cables and replaced the board.
Thanks again. :)
Yes my darling wife wanted the floor above (bathroom) tiled. 2 years later when she wants the kitchen replacing she mentioned she wants downlights in the ceiling that happens to be below the tiled bathroom floor.
Bite my lip or what?
please advise me on the best and legal way of running lighting cable for 6 downlights (replacing 2 lots of spots). The problem is getting around / through the joists, without wrecking my ceiling.
Cheers
