What Is An Annual Boiler Service

An annual boiler service involves a comprehensive examination of your boiler by a certified engineer. We will thoroughly inspect your boiler, uncover any issues (both existing and potential), and fix them before they escalate into more significant problems in the near future.

We Perform Thousands of Boiler Services in London Every Year. Heres Why:

Every year Imaa Plumbing provides annual boiler services to homes and commercial properties to ensure the safety of people, the health of your boiler and longevity of your boiler. There’s no need to replace something that works and is well looked after.

Boilers are safe when in good condition, but they can also pose serious safety risks if not maintained regularly. For instance, a faulty boiler can cause carbon monoxide poisoning. Safety should always be your priority, and an annual boiler service ensures just that.


As boilers age, their efficiency can decrease. A yearly service ensures your boiler is always running at its highest efficiency, which translates into lower energy bills.

Prevent Breakdowns

It can be devastating, especially in winter, if your boiler breaks down out of the blue. Regular servicing can detect potential problems before they become costly repairs.

Ensures Longevity

Regular servicing not only keeps your boiler working at its best, it can also prolong its life. That's right! Your boiler will thank you for this in its own way, by serving you longer.

Our Services Are Trusted By Experts In The Industry.

Annual Boiler Services FAQs

An annual boiler service is a proactive measure enlisting the expertise of a Gas Safe certified engineer to ensure your boiler is performing optimally and safely.

Typically, a boiler service should be scheduled annually. This frequency helps maintain its safety and efficiency by identifying and addressing potential issues before they can escalate.

While the duration of a boiler service can depend on its make and condition, usually, a thorough check by our engineers takes about 60 minutes.

All crucial aspects of your boiler are examined during a service, including its controls, internal components, flue and potential leaks, ensuring everything is operating as it should.

Annual boiler service, while not legally binding for homeowners, is highly advisable for the boiler's warranty validity and safety. For landlords, annual boiler servicing is a legal requirement for all rental properties.

The investment for a boiler service varies, typically ensuring security and efficiency. At Imaa Plumbing, we offer annual boiler servicing.

Delaying or ignoring your boiler service can lead to diminishing efficiency, escalating fuel bills, and potentially expensive breakdowns. It could even result in safety hazards like gas leaks.

Servicing a boiler is a task for trained professionals. It's considered unsafe and is illegal for anyone who is not a Gas Safe certified engineer to service a boiler in the UK.

Signs that your boiler may require servicing include decreased heat efficiency, unusual sounds, uncharacteristic shutting off, or visible black soot.

Only Gas Safe registered professionals, like our team, are legally permitted to conduct servicing on gas appliances, including boilers.
