What's the socket for??
The socket is above the hood not the hob. maybe I didn't make that very clear.
The socket is to power the hood but because of where the socket is, when the hood butts up to it the distance from hob to hood will only be 735mm.
I don't think the wiring will be long enough to move the socket further up the wall and wouldn't it be a pain in the ass to add an extra 20mm of wire to the existing stuff to make it movable?
