Funny enough, it is in a kitchen and the existing socket is just inside
the righthand side back of a gas hob! That is why I want it moving!!!

The fact that it is in a kitchen means that legally, you must submit a
building notice application. You'll probably find it costs:

2.00 for the socket (or reuse old one)
1.00 worth of cable
0.50 of crimp terminals
100.00 for inspection.

Bargain.
