How Often Should You Service Your Boiler?

Every boiler manufacturer recommends annual servicing to keep your boiler running safely and efficiently. Regular maintenance catches small problems before they become expensive repairs.

Annual servicing ensures safety through carbon monoxide checks, improves efficiency to reduce your energy bills by £100 or more per year, and maintains your manufacturer warranty.

A well-maintained boiler can last 15–20 years, compared to just 8–12 years without regular servicing.

A Gas Safe registered engineer performs a thorough inspection including visual checks of the boiler and pipework, testing for gas leaks and carbon monoxide, checking operating pressure and temperature, cleaning key components like the burner and heat exchanger, testing ignition and flame quality, inspecting all safety devices, and testing controls and thermostats.

A standard boiler service takes 30–45 minutes.

Late summer or early autumn is the ideal time — before the heating season starts. This catches any issues before you need your boiler most, and engineers typically have faster appointment times during the quieter months.

Annual boiler servicing at Empower Gas starts from £70, including a full inspection, safety checks, and a written report. We also offer combined service and landlord gas safety certificate packages for landlords.
