What Is a Gas Boiler Service?

A gas boiler service is essential for keeping your gas boiler in good working order. A gas boiler service is simply a review of your boiler, checking for any faults and repairing any damage that might spell danger in the future. Gas boiler services are important to conduct on a regular basis to ensure your household’s safety.

Why Should I Service My Boiler?

Getting a gas boiler service regularly is important for many reasons. The main reasons you should get a gas boiler service are:

  1. Ensure Your Safety
    A poorly maintained boiler increases the chances of carbon monoxide poisoning. On average, six people die each year in Ireland from unintentional carbon monoxide poisoning in their homes. This is usually caused by faults with the central heating system.
  2. For Insurance Purposes
    Most boiler warranties and home insurance policies require proof that the boiler is working properly. An annual boiler service will typically serve as confirmation. We recommend you check with your insurance company to see what exactly is required.
  3. Avoid Expensive Repairs
    The engineer will check for any minor issues with the boiler. Not fixing these minor issues could lead to bigger (and more expensive) repairs down the road.
  4. Decrease Your Gas Bills
    Servicing your boiler regularly ensures that it runs efficiently. By running efficiently, the boiler consumes less energy. This results in lower gas bills and also helps to reduce your carbon footprint!

What’s Included in a Gas Boiler Service?

Regardless if you choose to have your gas boiler service done by a local technician or a national gas provider, both should follow a gas boiler checklist, which generally includes the following:

  1. Visual Inspection
    The RGI will visually inspect the boiler. He/she will ensure that the gas boiler and any associated pipework are installed correctly and in the right position.
  2. Check the Controls
    The engineer will test the different controls to make sure they operate properly. He/she will check that all of the safety features are functioning correctly as well.
  3. Remove Casing
    The gas boiler casing will be removed to allow the engineer to check that the main components are functioning properly.
  4. Gas Pressure Check
    The engineer will perform a gas pressure check to make sure the boiler operates at the right gas pressure.
  5. Run a Flue Test
    The RGI will check the flue, which is the pipe that runs from the boiler to outside your house. He/she will check that nothing is obstructing its terminals, that it is properly fitted, and that no harmful emissions are being released.
  6. Cleaning
    The gas boiler parts will be cleaned as necessary.
  7. Attach the Casing
    The casing will be put back on the gas boiler and sealed.
  8. Get Your Checklist
    The RGI will leave you a checklist. This will have all of the information that you need concerning the safety of your gas boiler.

There are lots of items to check off during a gas boiler service. These include the following:

  • Boiler operation
  • Heating controls
  • Flame sense device
  • Pilot burner and related cables
  • High-limit thermostat
  • Gas and pressure flow
  • Flue effectiveness
  • Adequate ventilation
  • Electrical wiring connections
  • Location of the boiler and nearby combustible materials
  • Safety devices
  • Seals

After all the tests have been performed the engineer will tell you if anything needs to be repaired and provide you with a declaration of conformance, which you should ONLY sign if you are happy they have carried out all the tasks above.

A gas boiler service must be carried out by a registered engineer!

A gas boiler service must be carried out by a Registered Gas Installer (RGI). Here's an installer checker to help you look for a qualified professional. It cannot be performed by yourself if you are unqualified!

How Long Does a Gas Boiler Service Take?

A gas boiler service will take approximately 45 minutes to an hour to complete. If repairs are required, then it will likely take a bit longer depending on the type of repair necessary.

What If I Need Boiler Parts Replaced?

If parts of the gas boiler need to be replaced, those with older boilers will likely have to wait longer for the parts to be sourced and installed than those with newer boilers. This is because some of the parts can become obsolete rather quickly as newer and more efficient models are rolled out.

When Is the Busiest Time for a Gas Boiler Service?

If you need to make a callout, note that engineers may take longer to respond during the winter months. This is because most boiler and plumbing issues occur during this time when people are heating their homes, so don’t expect 24-hour availability.

How Often Should I Have a Gas Boiler Service?

You should get a gas boiler service once a year. This will ensure that it continues to operate efficiently and safely.

An efficient boiler leads to lower gas consumption and therefore lower energy bills. Safety is the most critical aspect of the gas boiler service. By ensuring that the gas burns properly, the risk of it leaking poisonous emissions is drastically reduced.

In addition to higher energy bills and potentially the leaking of toxic emissions, not having your gas boiler serviced regularly could also result in the warranty ending early. If it needs repairs or to be replaced, you’ll then be expected to foot the bill.

Are you a landlord with a gas boiler?

If you are a landlord, it's a legal requirement for you to get an annual Gas Safety Certificate for all the gas appliances at your property. These checks are to ensure you're renting out a property that is habitable for your tenants.
