Swords homes are mostly from 1981 to 2010: 37% built 1981 to 2000 and 30% from 2001 to 2010, across 15,232 households, and 74% heat with gas (Census 2022). Three installers that list Swords publish prices, from €2,150 for a General Gas combi, fitted, VAT not stated.
Dublin-wide, a like-for-like gas boiler replacement is €2,200–€3,300 fully installed with VAT and a new combi €2,500–€4,500 (GB Gas Services, re-read 29 October 2026). No grant pays for a new gas boiler.
Swords is reaching its first and second replacements
The five Swords divisions were built over thirty years. Glasmore and Seatown are the 1980s and 1990s town (49% and 49% built 1981 to 2000). Lissenhall and Forrest are the 2000s (40% and 36% built 2001 to 2010). So a 1990s house is on its second boiler, and a 2005 house is near its first replacement.
Oil is more common here than the Dublin average: 12% across Swords, and 18% in Seatown and 18% in the village. 29% of Swords households have four or more bedrooms.
