According to the electrician who installed a consumer unit, it was a 'spare wire' which used to be wired into the sockets spur- but after he left the wire unplugged, the socket in the hallway stopped working. He didn't say explicitly that they were linked, which I guess is the risk, but I'm sure it is.
K. Our spare wire was for an electric hob as we moved to gas.
Seems like an odd thing for a spark to say. Personally I'd get another spark in to look at it.
