I think there may be some confusion here, I think Doc reads it that you want to move rad. plus change single to dble skt.
I think you want to just move skt sideways and change to a dble. skt?
If I am correct then the only way I would go is to get a blank single cover plate to fit in place of single which is deemed to be a 'removable inspection cover' and would allow you to chase along wall at same height to new double socket and use 30Amp connector blocks behind cover plate.
thanks for that.
Yes I want to move the socket from behind the radiator and change it to a double. Is it ok to channel out horizontally for that short distance, I believe there are some issues with this,
yes, it's ok as long as u do it the way i described, this would mean you are wiring between points, even if one is only now a blank plate this should make it obvious that there might be cables run along there. this becomes a safe zone .
