I'm hoping to move some lights in our kitchen. I don't have access to the ceiling from above, unfortunately, so what I'm hoping to do is this:
Take the existing rose off the ceiling. Cut a hole approximately 10x15cm where the rose had been. Cut a 1cm-wide trench from the old rose position to the new position. Replace the 2-core with same, but long enough to reach the new position. Push the old rose into the hole and fix it to the nearest joist/ noggin. Fix the new light in position and run the 2-core from the old rose down the trench to the new light. Fix the hole with a small piece of plasterboard and then fill the hole and trench.
Is this a good plan? When I come to push the old rose back into the ceiling, do I absolutely need to fix it to a joist inside the ceiling?
