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 and occupied before 2011. The attic and walls must be well insulated by the time the job is finished, which the post-works BER confirms by rating them Good or Very Good or showing a Heat Loss Indicator of 2.3 or lower. You can insulate first or as part of the same project, with its own grants. 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 well insulated by the time the work is finished. The post-works BER must rate them Good or Very Good or show a Heat Loss Indicator of 2.3 or lower. You can insulate at the same time
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

Good to know

You can apply for the windows grant, the doors grant or both. Doors are €800 each, up to two.
You do not have to replace every window. But this is a once-off grant, paid once per property, so you cannot phase your windows and claim again later. You also cannot backdate a claim for work you've already done. SEAI's FAQ makes one exception: if you started or ordered a window or door upgrade since the government announcement on 27 January 2026, you can still apply, as long as you meet the scheme rules and use a registered contractor. SEAI gives no end date for this, so check with SEAI or your contractor first.
Windows and doors in the original house qualify. So do those in an extension built before 1 January 2011. Windows and doors in an extension built after that date do not, but the rest of the house still qualifies.
If the home already had SEAI grants for attic and wall insulation, SEAI treats the insulation as good. If not, check your existing BER Advisory Report for Good or Very Good, or ask a BER assessor. If the attic or walls need insulating, you can do it before the windows or at the same time, with SEAI's insulation grants. All the grants can then be paid together at the end.
A post-works BER is needed once the job is done and SEAI grant-aids it. You can choose a combined pre- and post-works BER service. SEAI's Homeowner Application Guide gives €50 towards the BER (€280 on a qualifying welfare payment) and says the BER grant is paid only on your first grant application.
SEAI's Homeowner Application Guide covers additional support for homeowners on its listed islands. If that is you, contact SEAI before you start works.
Do not order materials or start the work until your grant offer arrives, apart from the exception above for work started or ordered since 27 January 2026. SEAI gives no end date for that exception, so check with SEAI or your contractor before you order.
Manage it yourself with a registered contractor, or let a One Stop Shop handle it and take the grant off the price upfront.
To get paid, the job must also meet safety rules. Any room with an open-flued fire or boiler needs a permanent vent. Windows with a drop of more than 1.4 metres outside need restrictors. Windows and doors must meet the emergency escape regulations. Your contractor can advise on this.
SEAI's Homeowner Application Guide says you have 30 days to accept your grant offer, then eight months from the date of the offer to finish the work and send in the paperwork.
