Boiler Services in London

Don’t let boiler woes leave you in the cold! WaterGuys are your trusted experts for gas and electric boiler services in London. We handle everything from annual servicing and repairs to installations.

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.

WaterGuys annual gas boiler inspection and service include:

Clean your boiler and central heating filters – this removes built up debris and expands the lifespan of your boiler
Check safety elements and controls for any faults or problems
Look for potential hazards such as leaks or damage
Check gas installation pipes – ensuring clear lines of flow and secure pipework.

Test flue and emissions - dangerous fumes could lead to carbon monoxide poisoning
Review ventilation – poor ventilation could be dangerous for the homeowner
Assess the flue flow - clear lines of flow are essential to avoid potential breakdowns or leaks.
Check radiators - if required

FAQs About Boiler Services

Why should I service my boiler annually?

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.

How long does a full boiler service take?

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.

When should I get my boiler serviced?

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.
