Windows and doors cost in Ireland
There is no official cost figure for windows and doors in Ireland. SEAI publishes median costs for every other grant-aided upgrade, but not this one: the grant only opened in 2026, so no full year of completed cost data exists yet. What is confirmed is the grant, which is worth up to€5,600 for a detached house.
What the grant is worth
Windows are granted by dwelling type: €4,000 detached, €3,000 semi-detached or end of terrace, €1,800 mid-terrace, €1,500 apartment. External doors are €800 each for a maximum of two doors.
Full detail on the windows and doors grant →What suppliers publish
In the absence of an official median, the nearest thing to a real figure is a supplier publishing its own prices. These are the list prices of Airtight Windows & Doors, Dublin, for supply and installation, excluding VAT.
Read these as one company's prices, not a national average
This is a single Dublin supplier's published list. It is not a market median and it is not comparable to the SEAI figures on the rest of this site, which cover 47,067 completed upgrades. Prices elsewhere in the country, and from other installers, will differ.

|---|---|---|
| Single uPVC window | A-rated, any style, up to 2.4m | €600 to €1,200 |

Common questions
How much do new windows cost in Ireland?
There is no official figure. SEAI publishes median costs for every other grant-aided upgrade but not for windows and doors, because the grant only opened in 2026 and no full year of completed cost data exists yet. Airtight Windows & Doors, Dublin publishes list prices of €600 to €1,200 for a single A-rated uPVC window, and €12,000 to €15,000 to do a three-bed semi-detached house, both excluding VAT and including installation. That is one Dublin supplier's price list, not a national average.
How much is the SEAI windows and doors grant?
Up to €5,600 for a detached house. Windows are granted by dwelling type: €4,000 detached, €3,000 semi-detached or end of terrace, €1,800 mid-terrace, €1,500 apartment. External doors are €800 each for a maximum of two doors. Available for homes built and occupied before 2011. Windows must meet minimum U-value requirements.
Why does this page not give a median cost like the others?
Because SEAI has not published one for windows and doors, and we do not estimate. Every other cost page on Qualified.ie is built on SEAI figures covering 47,067 completed upgrades. Publishing a made-up national average next to those would make all of them less trustworthy.
Who can fit windows and doors under the grant?
Only a contractor on the SEAI register. Qualified.ie lists 663 registered contractors who do windows and doors, across 26 counties.
