Hi all, question on extending an existing ring main onto the surface and then re-joining back to in-wall. Is there a ‘correct way’ to do this, as I don’t see any sockets other than spurs with flex outlets that allow you to nicely exit a double, continue surface mount for a few sockets (behind kitchen units) and then back into an existing ring to complete the circuit? Obviously it’s not going to be seen so doesn’t matter a huge amount what it looks like, but just making a cable sized hole in the plasterboard next to the socket and then into trunking just doesn’t seem right?!
