hi there all,winter's on it's way and I need to get this sorted

I'm only getting a very occasional flow of hot water for bathing &
washing dishes from my gas central heating,approx once every month for
about 2-3 hours only.When the water does eventually flow it flows fine
like normal.

The radiators seem to be fine & I had the boiler serviced in January
this year.As usual the plumber didn't want to hang around to sort the
hot water out for me then & he told me it's probably a faulty valve
which I could probably sort myself.

Could anyone out there enlighten me with their wisdom as I've no
knowledge whatsoever of central heating systems and can't afford to get
one of these guys in to sort it for me.

I'm curious as to how the almost total lack of hot water is only a
problem in winter ?

That aside, presumably you have a combi boiler -

For those of you new to plumbing, that is a boiler that only fires up
when the house is too cold, or when you turn a hot tap on. It then
delivers a thin trickle of hot water to maybe one tap if you are lucky. ;-)
