    More than likely it's a missing earth.

    Probably the earth is not connected, or less likely, the neutral is not connected.

    There's a live, neutral and earth coming into the fused spur that the boiler is fed from?? So is it likely the the earth isn't making its way back to the board??

    Hello Crezzer.
    Is the boiler on its own dedicated radial circuit ? Or fed off an existing circuit please ?

    I would say it comes off the ring main, the twin and earth disappears through the ceiling and there's no seperate MCB for it.....

    Hi,
    Job number one is to find out which circuit it is 'on', and then where, and how it has been connected. Hopefully it wont be a concealed junction box, but from a 'local' socket. ;)
    Good Hunting and work safe.

    Be careful

    Was at one last week where the boiler guy identified reverse polarity.

    Turned out to be a L-E fault on the hob and a bad earth- 58 Ohms.

    All the house metal work (sink, radiators, boiler, hob. oven) was at 240V or thereabouts

    This has the potential to be real saftey issue. It requires checking out quickly

    You should use a competent person for the work, links below
