it sounds like your expansion tank is faulty or in need of repressurisation as a plumber of twenty years i stress do not attempt to do this yourself it is not a diy repair i know plumbers can be expensive but you really need an haeting enginner ( idid gas for 15 years) and a mainstream plumber would not normally have the know how to do this repair if your lucky repressure if not dont xpect change out of #200 quid
but htats cheap compared to doing it yourself cos you could easily wreck your boiler all parts on combies are xpensive and
i stress all work must by law be carried out by a suitably qualified person the days of diy boiler repairs have gone
