Annual Gas Boiler Service We Provide

Much like your car’s annual MOT and service, a regular annual boiler service should be a priority to ensure your boiler remains safe, efficient, and compliant with UK regulations.

While we’re happy to offer year-round boiler servicing, we would generally recommend booking your boiler service in the summer. This is a good time to prepare your home for the cold winter months.

Delaying your boiler service could cost you more in the future. An annual boiler service can help you avoid a breakdown requiring an expensive repair. What’s more, regularly serviced boilers run more efficiently, which translates to significant savings on your energy bills.

FAQs About Boiler Services

A faulty boiler can be dangerous. During a service, a qualified engineer will check for gas leaks and carbon monoxide risks, helping to keep your home safe. What’s more, regular servicing can help your boiler run more efficiently, which can save you money on your energy bills.

Newer boilers with easy access to components can be serviced quicker, sometimes in as little as 20 minutes. Older boilers, especially those with complex systems or undiagnosed issues, might take closer to 1.5 hours for a thorough cleaning and inspection.

In most cases, you should get your boiler serviced annually. This is the best way to ensure it’s running safely and efficiently. It’s generally recommended to schedule your boiler service during the summer months (July-September). This way, any issues can be identified and addressed before the cold weather arrives.
