Regular boiler servicing is vital to ensure that your boiler is running safely and efficiently. Poorly maintained or faulty boilers present a serious health risk to you and your family, because they can cause fatal carbon monoxide poisoning.

This checklist explains what to expect from a British Gas boiler service.

When should I arrange a service?

Arrange a boiler service at least once a year to ensure your boiler is operating properly at all times, details of how to do so can be found below.


Most people choose to have their boiler serviced in winter, when it is used the most. You may want to take this into account when booking your appointment – it may be worthwhile booking your service in advance or in a different season, such as summer.
