So......we had a great electrician in to do an unrelated Job and he mentioned that in half of the house (the original part) the wiring system was from the 60s and was not earthed. He said it was not a legal requirement but should a wire short or fray and touch ....er I don't know what.....the metal fittings would be live. Fine if the light fittings are plastic or pull cord, but the small screws would be live too.
Has anyone else come across this at all and did you choose to rewire- we were quoted 3-4000k.
