Central heating systems bring together a boiler, radiators, pipework, valves and controls, and a fault in one part can show up as a symptom somewhere else entirely. Our Gas Safe registered heating engineers (registration 968274) work across Cheam and Sutton on boilers, radiators, and the wider heating system.
Whether you have no heating at all, one cold radiator, a boiler showing a fault code, or you simply want an annual service to keep things running reliably, we cover it under this heading. We do not attempt to guess a fault over the phone, since heating problems often need hands-on diagnosis to pin down properly.
For gas appliances specifically, only a Gas Safe registered engineer should carry out installation, repair or servicing work, and we would never suggest attempting gas work yourself.
What a heating engineer covers
- Boiler repairs, breakdowns and servicing
- Central heating faults including cold radiators and no heat
- Boiler pressure and expansion vessel issues
- Heating controls, thermostats and programmers
- Power flushing to clear system sludge
How a heating fault is diagnosed
An engineer will typically start at the boiler, checking the display for fault codes, pressure, and flame behaviour, before working outwards to the system, checking pump operation, valve function and individual radiators.
Fault codes
Most modern boilers display a fault code when something is wrong, and noting this down before we arrive can help speed up diagnosis.
What you can check before calling
It is worth checking your thermostat settings, that the boiler has power, and that the boiler pressure gauge is within the normal range shown on the boiler casing, since these simple checks occasionally resolve the issue or at least narrow it down.
How charging works
Heating work is charged by time at our standard hourly rate, with a one hour minimum and 30 minute increments after that, plus any parts required. Gas safety certificates and boiler servicing are priced separately. See /our-rates for current figures.
