Gas Boiler Service

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.
