Boiler Losing Pressure?

What's usually going on

  • A small leak on a pipe, radiator or valve
  • A failed pressure relief valve or expansion vessel
  • Bleeding radiators repeatedly letting pressure out
  • A fault needing a Gas Safe engineer

Persistent pressure loss almost always means water is escaping somewhere — often a tiny leak on a joint, valve or radiator that we can trace and repair. Where the fault is inside the boiler itself, we coordinate a Gas Safe registered engineer so the right person does the gas work.

We're upfront about what's a plumbing fix and what needs a gas engineer, so you're not paying twice.

Frequently asked questions

Why does my boiler keep losing pressure?

Usually a small leak somewhere in the heating system, or a failed pressure relief valve or expansion vessel. We trace the cause at a set price.

Are you Gas Safe registered?

Gas work inside the boiler must be done by a Gas Safe registered engineer, which we coordinate. The system leaks and plumbing side we handle directly.

Is losing pressure dangerous?

It's usually a reliability issue rather than a danger, but a leak can cause damage over time, so it's worth diagnosing promptly.
