well I now know! on ur expansion vessel there is a valve, like a on a tyre... All u need to do is get a bike pump and add air into it until you see the pressure bar rise to 1bar and that should sort the problem... but if it persists losing pressure call out a proffesional

The expansion vessel needs to be pressurised, with air from a foot pump, to about 10 psi or whatever the manufacturer advises. (Fluctuating boiler pressure is an indication of this). Then refill your boiler via the filling loop to about 1 bar. Expect the pressure to rise a bit with the heating on, but if it drops again then there is a leak somewhere.
