It may seem like a silly question but I want to install a new socket in my garage and to avoid having to get new permanent wiring certified by an electrician I want to create a permanent ie wiring clipped to walls extension which plugs into an existing socke and terminates in a new socket... Is this contravieing regulations - or is it okay to do this? I also want to feed a lighting spur from this new, plugged in extension... Is this okay as well. Many thanks.
