My wife is not a trained electrician but even she spotted all the faults in the photos. I/we have seen all these things before, but never in the same house!!!
Fist time I've ever said this before on a forum just going by pictures.... ITS TIME FOR A REWIRE....... That house is an accident waiting to happen. Hope your house insurance covers you?
Telectrix is one (if not the) Best electricians on this forum. If I was unable to carry out my own house rewire, I would employ this mans expertise, you wont go wrong. (No bum kissing in saying that, we all know Tel and who better to have working in your home?)
