Boiler Service FAQs

How often should I service my boiler?

We recommend annual boiler servicing to maintain safety, efficiency, and warranty coverage. Regular servicing can prevent breakdowns, extend your boiler's lifespan, and is often required to maintain manufacturer warranties.

What's included in a boiler service?

Our comprehensive service includes checking all safety devices, testing gas pressure and flow rates, inspecting the heat exchanger, cleaning key components, checking controls and thermostats, and testing the flue and ventilation — plus a detailed service report and certification.

Will you identify potential problems during the service?

Yes, our engineers are trained to spot early signs of wear or potential issues. We'll advise you of any concerns and provide recommendations for repairs or replacements before problems become serious.

Do landlords need annual boiler services?

Whilst landlords are legally required to have an annual gas safety check, boiler servicing is also recommended to maintain efficiency and prevent breakdowns. We provide gas safety certificates and can arrange regular servicing schedules for multiple properties.

Can you service all boiler brands?

Yes, our Gas Safe engineers are qualified to service all major boiler brands including Worcester Bosch, Vaillant, Baxi, Ideal, and others. We carry common service parts and can advise on any brand-specific requirements.
