I've come come across 100's of houses that have this wiring in them. Gotta go. Definate rewire required here. Think safe. We came across this the other week and spent the day making it safe. The old wiring in our homes are a fire hazard but ordinary everyday people like you and I need to know this. Once i've completed your house rewire then Ill give you an electrical certificate of compliance which you can show your insurance company & get a possible reduction on your premiums. Bonus!
