This is class man, pure class, thing is, unless the place is being refurbed anyway, you know there's no way in hell they gonna stop trading for a week or more so you can sort this crap out.
Possible the I only thing I ever saw that beats this lot is a photo a guy at college showed me a few years back where he'd been to a house and in the place where the CU should have been, was a wooden board with several strips of terminal block mounted on it as the distribution. Only protective device in the house was the 100A cut out. Now that dude deserves a medal for ingenuity.
