Looking at buying this year, probably a 4-bed detached. Having been looking for months online, very few have been rewired. Usually there is a mish mosh of surface mount sockets on skirting boards, one socket in a bedroom, extension leads, no external lighting, etc, etc.
So looking for a ballpark, back of a fag packet, finger in the air, cost to rewire to modern requirements including outside power and lighting on all sides. Including consumer board, quality (white) face plates, excluding making good.
I'm thinking £5k ? NorthWest of England.
