What a new boiler costs in Finglas
No installer we found names Finglas. These say they cover all of Dublin, or north Dublin, and publish a supplied-and-fitted price on their own website (checked 22 and 23 October 2026; GB Gas Services re-read 29 October 2026). Listing an installer here doesn't mean it's the installer we pass your request to.
| Installer | Lists | Published price | Warranty | VAT |
|---|---|---|---|---|
| General Gas | north Dublin | from €2,150 | 10–12 yrs | Not stated |
| Dublin Gas Boilers | all of Dublin, from Dublin 12 | from €2,650 | 7–12 yrs | Not stated |
| Revolution Gas | all of County Dublin | from €2,600 | 10 yrs | + VAT |
Most of these prices don't say whether VAT is included. Ask for a written price with VAT, and check it includes the flue, the flush, the filter and the certificate. The Dublin installer survey has every published price side by side.

- Post-war terrace or semi, regular boiler. Most of Finglas. A combi frees the hot press: €600–€1,200 on top of a straight swap at GB Gas Services. See switching to a combi.

Repair or service first?
A boiler under 15 years old with one failed part is usually worth repairing; one that's breaking down every winter usually isn't. The repair or replace page sets out the test. For a yearly service or a repair call-out, our sister site covers boiler service in Finglas with local engineers' published prices.
