56v on neutral

A broken neutral would be at 230v or zero normally.

somebody with competence and test kit needs to get involved

Guys just thought I would update thread.

Went back today with my electrician.

Basically a socket tester only checks the path of a neutral. So the fact the socket tester indicates it was ok didn't mean it was not the problem.

He actually wired in a lamp that worked fine. However when he wired the heating in it broke the mcb.

It's a neutral fault somewhere in the house that needs to be rectified which he is going back to do.

Hard lesson here I think is the basic electric tests I should have carried out on the spur rather than presuming it was the heating wiring in the first place.
