Gas boiler service in Dublin 15

These six publish a gas service price on their own website and say they cover Dublin 15, by name or as part of all Dublin. Prices as shown on 22 October 2026, Sylo's re-read on 29 October 2026; sources at the bottom of the page.

Revolution Gas, based in Grange Abbey, has a page for Blanchardstown and publishes a service from €90 + VAT, about €102 with VAT at 13.5%, and a fixed €70 a year for boilers it installed itself. Dublin Area Plumbers covers D1 to D18, Dublin 15 included, at €140 + VAT, which it gives as €158.90. ServiceMyGasBoiler (€120, an online special), Energia (€135) and Sylo (€169, a fixed price) publish one price for all of Dublin. Bord Gáis Energy's €179 one-off service covers the first 45 minutes on site. Listing an engineer here doesn't mean it's the engineer we pass your request to.

• VAT. Two of the six quote + VAT. The other four don't say whether VAT is in the price. Ask for the price with VAT.
• "From" prices. A "from" price is for the simplest boiler. An older or harder-to-reach boiler can cost more.
• Landlords. A landlord gas safety inspection covers every gas appliance in the home and is priced on its own. Harris Heating publishes one at €199. See landlord gas safety certificates.

Once a year. Gas Networks Ireland: "You should have your boiler and other natural gas appliances serviced by a Registered Gas Installer once a year" (gasnetworks.ie, read 1 November 2026). Safe Energy Ireland, which runs the RGI register, says a gas boiler "needs to be serviced once a year, as recommended by the manufacturers" (rgi.ie, read 29 October 2026).

In Dublin 15 it's often a warranty question as well. 10% of homes in the ten Blanchardstown and Castleknock electoral divisions were built in 2011 or later, and 25% in Tyrrelstown (Census 2022). A boiler still under the maker's warranty usually needs a yearly service by a registered engineer to keep the warranty valid, so keep every service record with the warranty card.

Dublin 15 has more homes on the gas network than any other Dublin postal district. Gas Networks Ireland's meter data, published by the CSO, counts 32,789 homes with a gas meter in 2024, 11% of the 297,740 across the postal districts, and 2,623 more than in 2015, the biggest rise of any district. The median Dublin 15 home used 8,523 kWh of gas in 2024, against 8,153 kWh across the postal districts (CSO, Networked Gas Consumption 2024, tables 5C and 6C, read 30 October 2026).

Tyrrelstown is the most gas-heated of the ten divisions, at 83%, and the newest: 25% of its homes were built since 2011. Blakestown, the biggest division by far with 13,276 households, is the whole of the Ongar local electoral area and is 75% gas. Castleknock–Knockmaroon, the next biggest, is 78%.

The oil is in the older estates. Roselawn is 36% oil, and 89% of its homes were built before 1980. Delwood is 17% oil, Corduff 15% and Castleknock–Park 14%. Abbotstown is the apartment division: 50% flats, 40% privately rented, and 20% of homes heat with electricity, which isn't RGI work.

• Gas, so an RGI. With 74% of homes on gas and 8% on oil, nearly every boiler service in Dublin 15 is RGI work. Check any engineer's name on rgi.ie.
• Oil in the older estates. In Roselawn, Delwood, Corduff and Castleknock–Park, an oil boiler with a tank outside is common enough to check before you ask for a price. Oil is OFTEC work, not RGI: see oil boiler service.
• Newer homes, warranties. Keep the warranty card and every service record together. A missed year can cost you the warranty on a boiler that would otherwise be repaired for free.
• Apartments. 50% of homes in Abbotstown and 30% in Castleknock–Park are flats. A combi in an apartment has a short flue through the wall or a shared flue, and getting to it outside can need the management company.
• Landlords. 23% of households rent privately, 40% in Abbotstown. A landlord's gas safety inspection covers every gas appliance, not just the boiler: see landlord gas safety certificates.

• Look for a gas meter box on an outside wall or an oil tank in the garden. A tank means oil: an OFTEC technician, not an RGI.
• Find the make and model on the boiler sticker, and last year's service record if you have it.
• Under warranty? The warranty card says how often the maker wants it serviced.
• In an apartment, note the block and whether the management company controls access to the flue.
• Renting it out? Pick "Rented out" in the form, so the engineer brings the landlord paperwork.
• Write down any error code the display has shown.
