Windows and doors grant

Who can apply

Properties owned by the following applicant types are eligible:

• Homeowners
• Companies and owner management companies
• Registered charities
• Holiday home owners
• Approved Housing Bodies (AHB)
• Landlords 

The home must have

• an MPRN
• be built and occupied prior to 2011

Applicants can apply for the windows grant, the doors grant or both. 

Windows grant eligibility

1. You must be replacing existing single or double glaze windows
2. A post‑works BER is required after your new windows and doors are installed, and this is grant‑aided.
3. After the upgrade, your home must achieve a ‘Good’ or ‘Very Good’ Heat Loss Indicator on your BER Advisory report. Many homes already meet this standard.

How will I know if my home meets the required 'Good' or 'Very Good' standard?

• Check your existing BER Advisory report 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’ve already had both attic and wall insulation done with SEAI grants, then you’re all set, we can confirm this on our system.
• If you’ve had only one, or neither, you might still need some insulation to meet the standard. A pre-BER assessment is the easiest way to find out. We strongly advise you contact a BER assessor who carry out the assessment and will let you know if attic and/or wall insulation is needed before you can claim the windows and doors grant. Many homeowners choose a combined pre‑ and post‑works BER service.

Need extra insulation? Don’t worry, there are SEAI grants available to help cover the cost of attic and wall insulation if you need it. Learn more here.
