Grant for energy efficient windows and doors ordered from 27th of January 2026
The Sustainable Energy Authority of Ireland (SEAI) has announced a new grant for energy-efficient windows and doors. This home energy grant, often called the windows and doors grant Ireland 2026, is designed to help households upgrade poor‑performing windows and doors to more energy‑efficient replacements.
As confirmed by SEAI, homeowners who have commenced or ordered a window and or door upgrade since the government announcement on the 27th of January will be eligible to apply for grant support where they meet the scheme requirements and use registered contractors. As an approved SEAI installer, Fairco welcomes any initiatives that improve energy efficiency.

Grant for new windows and doors commenced since 27th January 2026
SEAI has confirmed that windows and doors ordered since the announcement on 27th of January 2026 will qualify for the grant. This means you can order your windows and doors now, manufacturing can begin, and be ready to apply for the grant when the online portal opens in March.
As an SEAI‑registered contractor, Fairco can install grant‑eligible windows and doors that exceed the U‑value ≤ 1.4 W/m²K requirement. All of our products are engineered for high thermal performance, with multi‑chambered profiles and high‑performance glazing that maximise solar gain and minimise heat loss.
Who qualifies for the Windows & Doors Grant?
The grant is not intended for people who simply want new windows; it aims to support deep retrofits that improve overall energy performance. Homes that fail the HLI requirement will need additional insulation, adding cost and complexity and potentially undermining eligibility.
To qualify for the grant, SEAI guidelines specify that you must:
Own a property built and occupied before 2011 with an MPRN (electricity meter number)
Replace existing single or double‑glazed windows and/or inefficient doors. New windows and doors must achieve a U‑value ≤ 1.4 W/m²K, with triple-glazing to be fitted on North-facing apertures and minimum double-glazing for other apertures.
Achieve a Heat Loss Indicator (HLI) of 2.3 W/m²K or lower (equivalent to a ‘Good’ or ‘Very Good’ BER rating) after the upgrade. Homes will need attic insulation, and many will also need wall insulation to reach this standard.
You’ll need an up-to-date BER certificate to verify your home’s HLI, to evaluate your home once the works are complete, before the grant is paid.
If your home already has a BER rating of B2 or better you will very likely qualify.
Apply only once; the grant cannot be backdated or claimed in stages. You must complete all of the works together.
Anyone who has commenced their project (which includes booking, surveying and deposit paid) since the scheme was announced on 27th January are eligible to apply.
Homeowners will have up to eight months post-installation to apply for the grant, and the contractor (Fairco) must be paid in full before the SEAI will issue the grant.
