I have the opposite problem. Pressure slowly dropping from 1.6ish to 0.4 over the course of a week. No obvious leaks. Signed up to a 6 month valiant service plan and engineer replaced a few bits including pressure release valve which I'm fairly sure wasn't sealing correctly as Airhead mentioned, but problem persists. Engineer coming out again next week but it's there any way I can check if the problem is in my pipes?
