Central heating repairs cover a broad range of work, from the boiler itself to the pipework, radiators, valves and controls that make up the wider system. We carry out heating repairs across Cheam and Sutton, whether the issue is a specific fault or general reliability problems with an ageing system.

Because heating systems are interconnected, an engineer diagnosing a repair will usually consider the system as a whole, checking whether a fault is isolated to one component or is a symptom of something happening more broadly, such as sludge build-up or an ageing pump.

If you know roughly what is wrong, our more specific pages on boiler repairs, radiator repairs, no heating and boiler losing pressure go into more detail on those particular issues.

What falls under central heating repairs

  • Boiler faults and breakdowns
  • Radiator and valve repairs
  • Pump, motorised valve and diverter valve faults
  • Thermostat, programmer and control faults
  • Pipework repairs within the heating system

How we approach a heating repair

An engineer will start with your description of the symptoms, check the boiler and controls, then work through the system checking components most likely to be responsible, rather than replacing parts speculatively.

Getting the most from a repair visit

It helps to note down when the fault started, whether anything changed beforehand (such as bleeding a radiator or a power cut), and any fault codes shown, before the engineer arrives.

How charging works

Heating repairs are charged by time at our standard hourly rate, with a one hour minimum and 30 minute increments after that, plus parts. See /our-rates for current rates.

Heating Repairs — common questions

How do I know if my problem is the boiler or the wider system?

An engineer can usually tell fairly quickly by checking the boiler's operation against what is happening at the radiators, though some faults need a bit more investigation.

Can you repair heating controls like thermostats and programmers?

Yes, we repair and replace faulty thermostats, programmers and related wiring as part of general heating repair work.

Do you work on underfloor heating systems?

We can look at underfloor heating manifolds and controls where they connect to a standard boiler-fed system; let us know the setup when you call.

What if the repair needs a specialist part?

If a part needs ordering for your specific boiler or control, we will explain the likely timescale and keep you updated.

Is it cheaper to repair or replace an old heating system?

It depends on the fault and the age and condition of your system. We will always assess repair first and be honest if we think replacement makes more sense.
