On rare occasions, your boiler pressure can seem low because the gauge is faulty and isn’t showing the correct pressure. In this case, you’ll need a boiler engineer to replace the pressure gauge. Why does my Worcester boiler keep losing pressure? Too much pressure on a boiler means there is an overfilling in the system. Hence, you need to bleed a radiator to release some of that. You are aiming to get a number between 1 and 1.5 bar. Bleeding means releasing trapped air.

But if it reads less than 1 bar, your boiler pressure is too low and needs re-pressurising. In either situation, we’d urge you to hire a heating engineer to inspect your appliance and recommend corrective action. Is It Time for a Replacement Boiler?
