    hi,

    I noticed yesterday evening that my above mentioned boiler seemed to take
    ages to actually light and stay that way. Normally I am used to a sort of
    clonk and and a second or two of ticking and then it is up and running.
    However yesterday and this again this morning I noticed that it takes about
    10 minutes before it actually stays running, in the mean time it keeps
    clonking.

    Sorry that the description is not too good!! Any idea if this is something
    fixable? I guess I will have to get someone out to look at it - iirc it has
    not been serviced since 1999 (when I moved into the house).

    Cheers,
    Matt

    ps. any recommendations for a decent boiler servicer in the Dorchester area
    of Dorset?

    I don't know this particular boiler but based on similar problem it could be
    a thermocouple which are cheap and easy to replace.

    Without knowing anything about this boiler you can safely say it does
    not have a thermocouple because the OP mentions ticking.

    Because everything nearly works there is no really serious problem and I
    strongly suspect crud/debris/wear in the ignition electrode of the flame
    sensing electrode.

    It might also be marginal air-flow proving that improves just enough
    when warmed up.

    Time it had a service.

    .... Electronic ignition

    IS the "clonk" the fan coming on ?

    If it's going click click click .... that's the ignition circuit trying
    to light the pilot, so that means the fan and pressure switch are
    probably OK, therefore:

    Most likely reasons are

    a relay in the pcb going high resistance,
    the HT lead has a break in it
    the electrode isn't in the pilot flame / it's burned away
    you have a bad earth (a bit of corrosion developing somewhere ?)
