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.
