Gas Boiler Service

A gas boiler service helps keep your heating running safely, efficiently, and reliably. It is a planned check-up that spots wear, verifies safe operation, and improves performance before small issues become breakdowns.

More information

What a gas boiler service covers

A thorough service focuses on safe operation, correct combustion, and efficient performance.

  • Visual safety inspection of the boiler, flue, and ventilation
  • Checks on seals, pipework, and gas tightness where applicable
  • Cleaning of key components where required (for example burner area and condensate trap)
  • Combustion analysis and adjustment checks to confirm safe, efficient burning
  • Testing of controls and safety devices
  • Inspection of system pressure, expansion vessel function, and condensate discharge
  • Performance checks to confirm the boiler fires, modulates, and shuts down correctly
  • Clear notes on results, any concerns found, and recommended next steps

Who this service is for

This service suits homeowners who want predictable heating and fewer winter call-outs. It is also useful for landlords and small commercial premises planning routine maintenance and wanting a clear record of condition. If you have noticed pressure drops, unusual noises, or inconsistent hot water, a service can help identify the cause early.

What happens during the visit

You will be asked about any symptoms, recent resets, or changes in performance. The engineer then carries out safety checks, internal inspection, cleaning where needed, and testing, finishing with combustion readings and functional checks. If a fault is found, you will be told what it is, what is urgent, and what can be planned.

After your service

You get a clear summary of what was checked and any recommendations to keep the system reliable. If parts are approaching end of life or settings are affecting efficiency, you will be advised on practical options. Ongoing annual servicing helps maintain safe operation and reduces the likelihood of avoidable breakdowns.

Frequently Asked Questions

How often should a gas boiler be serviced?
Most manufacturers and engineers recommend an annual service to maintain safety and efficiency. Yearly checks can also help protect warranty conditions and reduce unexpected breakdowns.
How long does a gas boiler service take?
Most services take around 45 to 90 minutes, depending on the boiler type, access, and condition. If issues are found or extra cleaning is needed, it can take longer.
Is a boiler service the same as a landlord gas safety check?
No. A service focuses on maintenance and performance, while a landlord gas safety check is a formal safety inspection and certificate for gas appliances and flues. Many landlords choose to book both for complete coverage.
Will a boiler service fix faults or stop breakdowns?
A service can resolve minor issues like low pressure, dirty components, or incorrect settings where appropriate. It cannot guarantee a breakdown will never happen, but it reduces risk by identifying wear and safety concerns early.
How should I prepare for a boiler service appointment?
Make sure the boiler, controls, and gas meter are accessible and clear of stored items. If you have had problems, note any error codes, noises, or patterns so the engineer can test more efficiently.
