Windows and Doors Grant
Windows: €1,500 for an apartment, €1,800 mid-terrace, €3,000 semi-detached or end of terrace, €4,000 detached. Doors: €800 each, up to two. You can apply for windows, doors or both.
What it is
Since 2026 you can get a grant for energy-efficient windows and doors on their own, with no full retrofit needed. The home must be built before 2011 with walls and attic already well insulated, and you must use an SEAI-registered contractor and apply before the work starts.
Who can get it
- You own the home, whether as an owner occupier, landlord, company, charity, holiday-home owner or Approved Housing Body
- The home was built and occupied before 2011
- The attic and walls are already well insulated (a Heat Loss Indicator of 2.3 or lower, or attic and walls rated Good or Very Good on the BER)
- You are replacing old single or double glazed windows with high-performing ones (U-value 1.4 or better), or replacing inefficient doors
- You use an SEAI registered contractor and apply before the work starts
- You can apply for the windows grant, the doors grant or both. Doors are €800 each, up to two.
- The home must already be well insulated in the attic and walls. If it is not, there are SEAI insulation grants to do that first.
- A post-works BER is needed once the job is done. SEAI grant-aids that too.
- Do not start the work until your grant offer arrives.
- Manage it yourself with a registered contractor, or let a One Stop Shop handle it and take the grant off the price upfront.
