Hi all,
I want to extend my ring main through a wall to another room.
Is it acceptable to pick-up from an existing socket and run the cable
behind the skirting then through the wall to the new socket? distance
will be about 2 mtr.
The room has concrete floor with drops from the roof which is
inaccessible, single story so would have to rip the roof up.

It's OK so long as the cable is running at the same height as the
socket. Whilst you can do what you like within 150mm of the ceiling,
this is not the case for the floor (basically because people tend to
fit skirting boards and the like in this area and could therefore
damage the cable. Going through the wall into the back of the socket is
fine, it's just that you can't go down from the existing socket and
then across, only straight across.

Alternatively you could run behind the skirting if there was enough
room to put the cable under metal protection which is earthed.

Hope this helps.
