Central Heating Repair

That's almost always trapped air, and it's fixed by bleeding the radiator. If it happens repeatedly across several radiators it can point to a bigger circulation issue worth checking.

This usually means sludge or debris has settled at the bottom of the radiator, restricting flow. A power flush often resolves it if it's affecting multiple radiators.

Could be a faulty TRV, a balancing issue, or a blocked pipe run to that radiator. We diagnose the actual cause rather than just replacing the valve and hoping.

It could be either, a boiler fault, a broken pump, a stuck motorised valve, or a thermostat issue. We check the whole system logically to find the real cause.

It depends on the specific fault. We diagnose first and give you a clear price before starting any repair work.

Yes, a failing pump is a common cause of poor circulation and cold radiators, and it's usually a straightforward same-visit replacement.

It controls whether hot water flows to your heating or hot water cylinder. They can seize or fail electrically over time, and a fault here often causes heating or hot water to stop working independently.

Bleeding a radiator yourself is safe and simple if you know how. If it needs doing repeatedly or doesn't fix the cold spot, that's when it's worth getting it looked at properly.

Yes, a stuck valve or failed pump can trigger pressure or circulation faults that show up as boiler error codes, even though the boiler itself is fine.

Most central heating repairs are diagnosed and fixed in a single visit. Get in touch with your postcode and symptoms and we'll give you a realistic timeframe.
