When the plumber came he found that the valve on the filling loop was open when it should have been closed. Don't know if this helps The previous owners to this property had a similar problem.

Have you tried topping up the system will the fill loop (the flexi pipe with a tap on it) to see if the system pressure increases. If the pressure gauge increases & then slowly drops then this would normally indicate a leak in the system. If the gauge stays steady then all is well. If the system pressure exceeds 3-4 bar then normally it will self vent using a safety valve incorperated within the boiler. Have you shut off a number of radiators which could increase system pressure when the boiler is firing? Failing that......bite the bullet & pay for a pro to sort it out. Hope you get it sorted.
