Thanks for the advice regarding using a quality junction box.

Is your present extension wiring plugged into the front of the
faceplate, or (more neatly) wired to the rear of it?

Where the cable enters the house, do you mean? There is no faceplate:
the existing cable just comes through the wall and into one end of a
rather basic (and indeed cheap-looking) surface-mounted box, about 3" x
2" with rounded edges, before the separate cable comes out of the other
end and heads off to the master socket.


the centre of the surface mounted box cover is probably moulded with either
BT or, if very old, GPO.
