Thanks for replying Atthebottomofthesea - apparently the lighting circuit is not earthed, which was normal for a house built early 60s but is not recommended now, though not illegal or unsafe providing certain safeguards are observed. (I have done a crash course on electrics this afternoon via google).
Apparently it's safe as long as non metal or double insulated (class 2) wall and ceiling lights are used, and no metal light switches etc.
We told them we would replace the light fittings with class 2 ones, which we can do straight away. Wickes do them, we discovered this afternoon.
But they may want us to pay for the rewiring which when I think about all the disruption - chasing into the walls, floorboards up, ruined flooring everywhere, redecoration - I have a headache just thinking about it never mind we don't have the money.
We won't know anything more until Tuesday. We're booked to move on Friday. Panicking a bit!
How's things progressing on yours? Are you still waiting till 1st June for the scaffolding to be removed? That was meant to be our moving day.
How's everyone else getting on? Some success stories would be good to cheer up the thread.
