Questions people ask
How much is a combi boiler installed in Dublin?
7 installers covering Dublin publish a combi price. The median is €2,685, from €2,150 to €4,800.
Is there a grant for a new boiler?
No. In SEAI's own words, it "does not provide grants for the installation of new or replacement fossil fuel boilers, such as gas or oil boilers" (SEAI). You may get the €700 heating controls grant if your home was built and occupied before 2011 (SEAI). The €2,000 boiler scrappage grant only applies when a heat pump replaces the boiler.
