I am turning a door around, to hinge the other side. So I need to move the light switch to the other side and even I can do this kind of wiring task I just take the switch out, connect a wire to the existing, cut a channel in the plaster then hide it under the door architrave to bring it round to the right position. The old hole in the plaster with the join in the wire and the new wire in its channel will most likely be filled with a big dollop of stiff polyfilla. The walls are brick internal partitions.
What's the best way to join the wire? I could use choc blocks and tape but I have a feeling there might be a better 'approved' method of connecting and hiding them. I don't want access and I don't want a visible plate. I am not that fussed about regulations but might be sensible about safety.
