The most common fault is a leak in your central heating circuit. An engineer will test this by charging the system and then probably shutting off the flow and return valves to prove where the fault lies. Check for any weeps from the radiator couplings. You may be lucky and find one weeping into the floor un-noticed and the coupling may just need tightened.

That's a good point. Your pressure relief pipe could possibly be dripping away un-noticed. If the seal has gone on the pressure relief valve it shouldn't be an expensive repair.
