Boiler service in South West London

A boiler service is an annual safety and efficiency check of your gas boiler. Swift 24-7 Plumbers services boilers across South West London, testing combustion with a flue gas analyser, checking every safety device, and recording the service so your manufacturer guarantee stays valid.

Why service your boiler every year?

Boiler manufacturers recommend an annual service, and most guarantees require one. A yearly service matters because small problems such as a weeping seal, a blocked condensate trap or poor combustion are cheap to fix early and expensive to fix after the boiler breaks down in January.

  • Safety. The service confirms the boiler is burning gas correctly and that flue gases are leaving the property safely.
  • Efficiency. A clean, correctly set up boiler uses less gas to heat the same home.
  • Reliability. Most winter breakdowns we attend could have been spotted at a service.
  • Guarantee. A recorded annual service keeps most manufacturer guarantees valid.

What our boiler service covers

  1. Visual inspection of the boiler, pipework, flue and ventilation.
  2. Flue gas analysis to check combustion and carbon monoxide levels.
  3. Gas pressure and gas rate checks against the manufacturer's figures.
  4. Inspection and cleaning of the burner, heat exchanger and condensate trap where required.
  5. Checks on seals, the fan, the expansion vessel and system pressure.
  6. Testing of the safety devices and controls.
  7. A written service record and an update to the boiler's Benchmark log.

Landlords and letting agents

A boiler service and a landlord gas safety certificate are two different things. The gas safety check is a legal requirement for rented homes, while the service keeps the boiler healthy. We can carry out both on the same visit to save you and your tenants a second appointment. See our gas certification page for details.

Common questions

How long does a boiler service take?

A standard boiler service usually takes under an hour. It can take longer if the boiler needs cleaning or a part such as a seal or condensate trap needs replacing.

Is a boiler service the same as a gas safety certificate?

No. A boiler service is maintenance of the boiler, while a landlord gas safety certificate (often called a CP12) records safety checks on every gas appliance in a rented property. Swift 24-7 can do both on the same visit.

When is the best time to book a boiler service?

Late spring to early autumn is ideal, because any faults found can be fixed before the heating season starts. That said, an overdue service is worth booking at any time of year.
