An annual boiler service is essential for safety, efficiency, and maintaining your manufacturer warranty. During a service, our Gas Safe registered engineers carry out a comprehensive inspection and test of your boiler, checking all safety-critical components, measuring gas pressure and flue gas readings, inspecting the heat exchanger for leaks or damage, and verifying that controls and safety devices are operating correctly. Regular servicing catches developing faults before they become expensive breakdowns, keeps your boiler running at peak efficiency to minimise gas bills, and ensures it operates safely with no risk of carbon monoxide leaks. Most boiler manufacturer warranties require an annual service to remain valid — missing a service can void your warranty, leaving you unprotected if a major component fails. Our service includes a visual inspection of the entire heating system including the boiler, flue, pipework, and controls; a combustion analysis to check the boiler is burning gas efficiently and safely; cleaning or replacing the condensate trap; checking the expansion vessel pressure; and a written service report. We service all major boiler brands across the Banbury area and can usually complete a service within 45 minutes to one hour.
We inspect the boiler casing, flue, ventilation, pipework, and connections for visible signs of damage, corrosion, or deterioration. We also check that the boiler's safety label and gas rating plate are present and legible.
We fire the boiler and test it across all modes — central heating, hot water, and standby. Gas pressure, water pressure, and pump operation are measured and compared to the manufacturer's specification.
Using a calibrated flue gas analyser, we measure the boiler's combustion efficiency and check for safe CO/CO2 ratios. This confirms the boiler is burning gas cleanly with no risk of carbon monoxide production.
You receive a written service record including all readings, any observations or recommendations, and confirmation that the boiler has passed its annual safety and performance check. We stamp your service book or provide a digital record.
A standard boiler service in the Banbury area costs between £70 and £100. This includes the full inspection, combustion analysis, and written service report. Landlord Gas Safety Certificates (CP12) covering the boiler and other gas appliances are available from £80. We offer annual service reminders so you never miss a service date.
Every 12 months. Annual servicing is recommended by all boiler manufacturers and is usually required to keep your warranty valid. The best time to book is in late summer or early autumn, before the heating season begins, when appointments are easier to arrange.
A Gas Safety Certificate (CP12) is a legal requirement for landlords renting out a property. It confirms that all gas appliances, including the boiler, have been checked by a Gas Safe registered engineer and are safe to use. The certificate must be renewed annually and a copy provided to tenants.
The service fee covers the inspection and safety checks. If we find a fault during the service, we will explain what is wrong and provide a separate quote for the repair. Minor issues such as low water pressure or a sluggish condensate trap are often resolved during the service visit at no extra cost.
