What is the (legal?) position re me / one adding an extra double socket (next to an existing) in a living room for / with a non d-i-y mate?
I mean, I believe we (or 'competent people' at least) can do some electrical stuff for ourselves but does it still need signing off to maintain the 'tested' status for insurance purposes etc?
If it was 'ok' for me to do it (for / with him as a mate, not as a 'job' etc), would it be better to try to get the new socket into the existing ring  or failing that, could it be a spur (assuming 2.5mm T&E)?
Cheers, T i m
 I think it's all plasterboard on battens but as yet have no idea how much room there is behind the location of the additional box (or where the battens are etc).
