    So not the fuse then. :(
    Any thing else I could check before calling in the dear (very dear) technician.
    It hasn't been used for a few months but was working perfectly.

    I think that you have misunderstood what meercat has said.
    He is suggesting that boilers such as this are generally be fed from a 3A fuse.

    However boilers are normally fed from a fused spur outlet rather than a plug top.

    So perhaps if you change the fuse in the plug top your boiler will work.

    If it has not been run for a while, and there is power at the boiler (fuse ok etc), then check reset buttons on the boiler, and/or check there is enough pressure in the system if its a sealed one, by looking at the pressure gauge on or at the boiler which should have between 0.5 and 1 bar with the heating not running, or if its not a sealed system, check that there is enough water in it by checking that the expansion tank in the attic has water in it.

    Sorry, I understand what you mean.
    The plug top brings power to the boiler house. Changed the fuse in it, but no luck.
    Will get to check the other suggestions today, when it warms up a bit!
    Thanks for the help so far.
