What does a boiler service include?

Regularly getting your boiler serviced is an important step in ensuring that it runs efficiently and prevents future breakdowns. In this article, we will walk you through the inspections and checks that are usually included in a boiler service to give you a better understanding of what to expect during a boiler service.

In this guide, we’ll cover:

What is the purpose of a boiler service?

The purpose of a boiler service is to ensure that the boiler is running efficiently and safely as well as to identify any potential boiler issues as early as possible.

Inspecting the boiler’s efficiency

During the boiler service, engineers will ensure that your boiler is running efficiently which ensures that your boiler is not using energy excessively, helping to keep your energy bills as low and as accurate to your consumption as possible.

Identifying potential boiler issues early on

Regular boiler service is an essential step in ensuring your boiler’s longevity. Certified boiler engineers will thoroughly inspect your boiler to identify any problems early on during the boiler service.

Protecting your household’s safety & boiler guarantee

Ensure your boiler is up to the safety standards by booking a boiler service. Additionally, boiler service ensures that you will maintain your boiler’s guarantee after the first year.

What does a boiler service typically include?

Boiler service usually includes a range of tests and inspections to assess the safety and efficiency of your boiler as well as identify any concerns so that they can be addressed as soon as possible.

Common set of checks during boiler service:

Visual check

The boiler engineer will inspect your boiler, looking for any leaks or corrosion.

Pilot light

If you have an older boiler, the engineer will assess the colour of your boiler's pilot light. This check ensures that your boiler is burning fuel properly (fuel that is not fully burnt can be a safety risk).

Internal part check & clean-up

An experienced member of your local boiler engineer team will check the internal parts of your boiler and clean them thoroughly. This usually includes vital components such as the spark probe, main injector, heat exchanger, burner, and safety devices.

Flue terminal inspection

Your engineer boiler will inspect the flue terminals. This is an important safety measure to ensure that the terminals are not blocked and that they have been sealed correctly.

Pipework inspection

The water and gas pipework will be checked carefully for wear and tear.

Gas pressure & flow setting review

The engineer usually investigates your gas pressure and flow settings. If these are not at the right level, they usually get adjusted.

Boiler operations & controls check-up

Finally, they will switch on your boiler, checking that it is operating correctly and that the temperature controls are working properly.

What reports should you expect to receive after a boiler service?

Once the engineer has finished the boiler service, they will usually give you a boiler service report containing details and confirmation of all of these checks. They will also advise you on any necessary boiler service needs if applicable, take a look at our article about ‘how much does a boiler service cost in 2022’ to find out more about how much it will cost to service your boiler.

Lastly, don’t hesitate to ask the boiler engineer questions if there are any parts of the boiler servicing report that you’re not sure about.

Does a boiler service include a gas safety certificate?

In short - no. Boiler service does not automatically include a gas safety certificate and if you do require one, you usually have to book them separately. When the engineer services your boiler, they will update the Benchmark Service Record to make sure it’s in accordance with Building Regulations and meets your boilers garantee conditions.

It is important to establish the difference between a boiler service and a gas safety certificate:

A boiler service is a safety check and service of your boiler and heating controls, whilst a gas safety certificate is a legal document which states that your gas appliances and installation are safe to use.

Only the landlords of properties that use gas for heating, hot water, or cooking are required to have a gas safety certificate.
