Boiler Service Checklist

When it comes to maintaining the performance and safety of your boiler, scheduling regular services is crucial. In this guide, we provide a detailed breakdown of what to expect during a boiler service, how often you should schedule one, and how to find a qualified engineer.

The Importance of Regular Boiler Services

Scheduling a boiler service at least once a year ensures the safety and efficiency of your central heating system. Regular services not only help prevent unexpected issues and costly repairs, but they also protect your boiler’s warranty.

Duration of a Boiler Service

A standard boiler service should take approximately 45 minutes to an hour, depending on whether any immediate repairs are needed. Most engineers will work with you to arrange a date and time for the service that suits your schedule.
