Not my DIY.....one of the previous owners.
Looks like every time they wanted another plug socket, they just tapped nto the nearest cable.
We managed to trace lots of the wiring back, and as far as we can tell the whole of the kitchen and the heating system is running off the back of a plug socket in the living room
The downstairs seems to be not a ring or radial, but star wired....and not back to the main fuse but to a small junction box under the bathroom floor!!!!
Basically another mad week of rewiring trying to get it finished before the new carpets arrive to be fitted!!!!
And no, I'm not doing it myself, I had the sense early on to call in a professional electrician...and he's struggling to work out what the hell is going on and why the house hasn't burnt down yet.
It's looking very likely that I won't be able to take a whole weekend out this side of Christmas........
