Call out to a b&b late afternoon ,various little jobs,but,behind a king sized bed was a broken socket.This is where it goes pear shaped,cable rubber,all cables are bare,insulation just crumbling.Its getting on a bit now,can't isolate the cable,cos other sockets are on same circuit going to other rooms,& all occupied,I no I shouldn't attempt this but,under pressure a bit,so me being clever, thought disconnect the cable from where it's coming from,another socket in the nxt bedroom.Once again all cables are bare,rubber,left in a hurry,with all fuses taken out,gotta return today,not looking forward to it.obviously major probs here,but the most annoying thing,other sparks have continually done work here, not one mentioned rubber cabling ,why?
