Boiler losing pressure: what could be happening?

Repeated pressure loss can have several causes, including leaks or system components. Continually topping up without understanding why pressure falls is not a long-term solution.

What to do next

A sensible first check

Record how quickly pressure drops
Look for safely visible leaks around radiators and pipework
Note any fault codes or unusual discharge outside
Provide the boiler make and model when arranging help

When should you act?

If the boiler stops working, pressure falls rapidly or there is an active leak, arrange professional attention.

This page is general guidance, not a diagnosis. If the issue involves immediate danger, active water near electrics, fire, gas, structural instability, unsafe working at height or another urgent safety risk, use an appropriately qualified professional or emergency service rather than relying on online advice.

Common questions

Should I keep topping up boiler pressure?

Occasional correction may be part of normal operation for some systems, but repeated pressure loss should be investigated.

Can a small radiator leak cause pressure loss?

Yes, leaks within a sealed heating system can contribute.
