Getting a gas boiler service is critical for making sure that it runs efficiently and safely. So how often should you get your gas boiler serviced? How long will it take and how much will it cost?


In this guide, we break down everything you need to know about getting a gas boiler service. For details about servicing an oil or electric boiler, head to our general boiler service guide.

Why should I service my gas boiler?

Getting your gas boiler serviced regularly is important for many reasons. The main reasons you should get a gas boiler service include the following:

  • To 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.

  • 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.

  • To 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.

  • To 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 a gas boiler be serviced?

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.

What is done in a gas boiler service?

A gas boiler checklist will generally include the following:

  • Visual inspection — The RGI will visually inspect the boiler. He/she will ensure that the gas boiler and any associated pipework is installed correctly and in the right position.

  • 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.

  • Remove casing — The gas boiler casing will be removed to allow the engineer to check that the main components are functioning properly.

  • Gas pressure check — The engineer will perform a gas pressure check to make sure the boiler operates at the right gas pressure.

  • 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 there is nothing obstructing its terminals, that it is properly fitted and that no harmful emissions are being released.

  • Cleaning — The gas boiler parts will be cleaned as necessary.

  • Attach the casing — The casing will be put back on the gas boiler and sealed.

  • 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

A gas boiler service must be carried out by a Registered Gas Installer (RGI). It is illegal for anyone else to conduct the gas boiler service. To search for an RGI in your area, click here to find a list of the RGIs in your area.

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 is a gas boiler service in Ireland?

A recent survey conducted by OnlineTradesmen.ie found the average cost of a gas boiler service to be €73. Costs vary depending on the company and location.

A gas boiler service tends to cost more in urban areas than it does in rural locations. In some rural areas, the survey found gas boiler services for as low as €60.

Some companies offer payment plans that allow you to pay for the gas boiler service in installments. This can be helpful if you need a last-minute gas boiler service and haven’t been able to budget to pay for the work in full.

The main gas providers (Bord Gáis Energy, Electric Ireland, SSE Airtricity and Energia) offer boiler care plans that include the annual gas boiler service. These plans would include the added benefit of labour and parts. This payment can be joined with your energy bill each month, thus making it easier to manage.

In the following table, we’ve listed the energy suppliers that provide gas boiler servicing, as well as the price for the most basic boiler service.

Energy supplier Cost
Electric Ireland €89
Energia €95
SSE Airtricity €99
Bord Gáis Energy €99

Many independent companies provide cheaper gas boiler services than energy providers. However, organising it through your energy provider is an easy way to guarantee that the service will be carried out by a Registered Gas Installer (RGI).

Another advantage of choosing your energy provider to carry out your gas boiler service is that you can often manage the boiler service and your energy supply via the same account online, thus leaving you one less username and password to keep up with.
