What is the SEAI Window and Door Grant?
The new SEAI grant is part of the Better Energy Homes Scheme and allows for energy upgrades in many homes making them more comfortable and energy efficient. Grants for windows and doors were previously only available for homes undergoing deep retrofits. Now, eligible homeowners will be able to apply for a stand-alone grant of up to €4000 for the installation of energy-efficient windows and up to €800 per energy efficient door (max 2). This new grant is designed to make upgrades more accessible for more homeowners.

To qualify for grant payment once works are complete, your home must meet all the conditions of the grant in the post work BER. These requirements must be achieved for SEAI to approve and pay your grant. Upgrading the windows and doors on their own may not be enough for the home to achieve the required post-works standards. You may need to consider additional insulation measures such as attic or wall insulation. The grant application is managed directly between the homeowner and the SEAI, and it is the homeowner’s responsibility to ensure that all scheme requirements are fully met to qualify for the grant.

Eligibility: Who Qualifies for the SEAI Window and Door Grant?
Check if you are eligible first
- The house must be built and occupied prior to 2011
- The house must have good attic and wall insulation. See below to understand what 'good' means
- You must be replacing existing single or double glaze windows with high performing windows (1.4W/m2K or better)
- You must be replacing inefficient doors
How will I know if my home has good attic and wall insulation?
- Check past upgrades. If the home previously received SEAI grants for attic and wall insulation, then good insulation is in place.
- Check your existing BER. If your existing BER has an Advisory Report, check to see if your attic and wall insulation is 'Good' or 'Very Good'. You can find your existing BER certificate and advisory report on the national register. You will need your MPRN to access your BER.
- If you still don't know if your attic and walls have good insulation, get advice from a BER assessor. A BER assessor will look at the older BER's or perform a pre-work BER assessment. If they indicate you need to upgrade either attic or wall insulation, then grants are available from SEAI for these measures.
- At Senator Windows we recommend that all customers have a valid BER in place (issued within the last five years) prior to installation to ensure grant eligibility. As a post‑works BER is required in any case, it is best to complete the pre‑works BER in advance.
- The SEAI now offer an AI assistant to help you check your eligibility for the SEAI Windows & Doors Grant.
SEAI Grant Payment Criteria
- A post-works BER is required after new windows and doors are installed, and this is grant-aided. Homeowners may choose a combined pre- and post-works BER service.
- New windows and doors meet the required U-values (1.4 W/m2K, or lower such as 1.3). This is confirmed on the declaration of works form signed by the contractor and homeowner.
- The property must meet a Heat Loss Indicator (HLI) value of 2.3 W/ K·m2 or lower OR the attic and walls are noted as "Good" or "Very Good". This indicator will be in your post-works BER Advisory Report.
- The property must be ventilated for healthy living conditions and good indoor air quality, in particular any room with an Open Flued Appliance must have a permanent vent to ensure the home is safe.
- Windows through which a person, particularly a child, may fall and which have an exterior drop greater than 1.4m from the bottom of the opening to the ground must have suitable restrictors fitted.
- Windows and doors must comply with the emergency escape regulations, including suitably sized openings and suitable locking mechanisms on escape windows.
- It is the customers sole responsibility to ensure that your property meets the full eligibility criteria when applying for SEAI retrofit grants.
Before You Apply
Choose how to manage your upgrades. You can either:
- Apply yourself. Apply for the grant and manage the upgrade using a registered contractor such as Senator Windows. The grant is paid directly to you once the works are completed.
- Use a One Stop Shop to manage the upgrade. The One Stop Shop applies for the grant on your behalf and looks after the upgrade from start to finish. With this route, the grant is deducted upfront from the cost you pay the One Stop Shop.
How to Apply
This is the process to follow if you're applying for the grant yourself. If you're using a One Stop Shop, they will manage this process for you.
- Get a quote from registered contractors, including Senator Windows
- Apply to SEAI for grant offer
- Wait to receive a grant offer from SEAI (do not commence works prior to receiving your grant offer)
- Complete the works
- Get a post works BER
- Submit required documents to SEAI
