Take Volt stick/pen, shove it up someones arse as thats as useful as it gets,

For example, rub it up and down on your arm - wow your "live".

I can tell that one end goes down into a small partition wall, joined by wires for a light switch, and all there is on this wall is a light switch and a single socket, checking the socket it is not a spur. The other end of the cable disappears down a void at the house wall.

Might be three core and earth? Bit thicker. Part of hall stair and landing lights......

Firstly identify and label the fuses/MCBs in your consumer unit.

Get one of the contactless voltage indicators. Like this

Its then a simple job to turn off the circuits one by one and see when the voltstick stops showing that a voltage is present, or not.

NOTE:
In most houses there are only lighting circuits in the loft.
What do you need the socket for? 3KW fire or a TV amp?

NOTE2
DO NOT use the voltstick to determine that the circuit has been isolated if you are doing actual work on the wires. Check out the Safe Isolation section in the WIKI.
