Just wondering what everyones thoughts are on boiler supplys fair enough if a new boiler is put in place of an old boiler use the existing wires that were there.But what if the boiler has moved position I think it should be re-wired on a seperate circuit with a install cert.Other sparks spur off the house ring main i.e under the floor with a joint box feeding the boiler spur to save time.Yes its feeding the boiler spur with 2.5 fused down in there with a 3 amp fuse i dont like this whats everyones thoughts on doing it like this?
