Hello I’ve recently bought a house and have been doing some rennovating, after pulling down some of the plasterboard I’ve discovered the supply to the meter comes in from under one of the walls and travels maybe 3 m along and up the wall to the meter, the wire is completely unsupported, apart from where it is connected to the meter and, as far as I can tell, there is no protection device like a circuit breaker or fuse for that part of the line as it just comes out of the ground then into the meter. I don’t know what the safety rules are for the supply cable, but it seems a bit dodgy having a length of cable loose inside my house, which I cannot isolate and cannot guarantee would trip if the insulation was damaged and it shorted.
I’m wondering is this normal? If not, is it my or OVOs responsibility to rectify?
