Hi all,just after a bit of help if possible.

In the process of decorating my lounge at the moment & i have a question!
Have removed my old fireplace surround and also an electric fire,obviously this has left me with a chunk of wiring hanging out of the wall,this was fed from a 13a fused spur socket further along the wall.
Now what i want to know is can i just use that existing cable to wire up a double socket instead?
Any help would be much appreciated,thanks!
