So my first question is : am I correct in thinking that by converting the existing spur to a fused spur - I can then extend further sockets off this?
My second question might raise a few eyebrows - and I think I can guess what the answer will be. On exploring the route for the new socket - it became clear that raising the floorboards (chipboard type - house 25 years old) is going to be quite difficult. Broke one of the boards already while raising it. They are nailed and screwed very firmly indeed.
I have removed all the skirting and will be replacing with new. There is a nice little gap between the plasterboard and floor which is fairly deep and could easily take cable, perhaps in conduit. Would it be completely out of order to route the new cable in this gap - which would end up behind (at the bottom of) the new skirting? I guess future owners will conceivably stick long nails or screws into the skirting - so I guess this is out? Or is there some accepted way of doing this - such as putting the cable into some sort of armoured protection?
