Why Should I Service My Gas 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!

How Often Should I Service My Gas Boiler?

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.

If you are a landlord, an annual gas boiler service is a legal requirement.

How Do You Service a Gas Boiler?

In Ireland, any maintenance done on a gas boiler needs to be conducted by a certified engineer. Disregarding this guideline not only jeopardizes your gas boiler warranty but also places your home and family's safety at risk.

There are two main avenues homeowners can choose to select a gas boiler service provider:

  1. Choose an energy provider to conduct the gas boiler service
  2. Choose a local technician to conduct the gas boiler service

We break down the details for each option below.

Can My Energy Provider Service My Boiler?

For many, opting to have their gas boiler serviced by their energy provider is the easiest and simplest solution. The gas boiler service can be added to the cost of their monthly energy bill and one can be assured that the technicians are fully certified by the RGII.

The drawback is that they can be more expensive than a local technician. This is often because the service comes as part of a monthly insurance plan, leaving one with the impression of not getting good value for their money.

The main energy providers with offers are:

  • Electric Ireland boiler service
  • Energia boiler service
  • SSE Airtricity boiler service
  • Bord Gáis boiler service

We examine each provider's gas boiler service plans below.

The Electric Ireland boiler service is available for just €89. The service includes a comprehensive 26-point safety check. You get 24/7 support in case of a gas boiler failure and the engineer will also detail exactly how efficient your device is, as well as give you advice on how to reduce your energy bills.

The service seems great and can be booked online. However, the provider is not well-reviewed on the website Trustpilot, receiving only 1.6 out of 5 stars.

What's Energia Boiler Service Like?

An Energia gas boiler service costs €95. This boiler service includes a 28-point check service, as well as a 30-day warranty. To book a boiler service with Energia, you’ll need to call 1850 719 377 or arrange a callback on the supplier's website.

What Is Done 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 cCasing
    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

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.

When in doubt, the SEAI has produced a useful checklist that you can use while your boiler inspection is being carried out, to make sure that you’re getting your money’s worth.

You need a Registered Gas Installer for your gas boiler!At the risk of repeating ourselves, 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.

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.

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.

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 Much Does a Gas Boiler Service Cost in Ireland?

As we saw earlier, rural areas can hire a local technician for as low as €60 to service their gas boiler. Those living in urban areas can expect to pay more between €80 to €100. The average cost of getting service on a gas boiler in Ireland is €73.

In the following table, we’ve summarized the different gas boiler service costs in Ireland so you can have a glance at which option suits you best.
