Yes. Landlords can get the SEAI windows and doors grant. SEAI lists landlords, holiday home owners, companies, owner management companies, Approved Housing Bodies and registered charities as well as homeowners (seai.ie, checked 3 November 2026).
The amounts and rules are the same as for an owner who lives in the home: €1,500 to €4,000 for the windows by home type, plus €800 a door for up to two, in a home built and occupied before 2011 that passes the BER heat loss test.
Can a landlord get the window grant?
Yes. On its windows and doors page, SEAI names landlords among the people who can apply, alongside homeowners, holiday home owners, companies and owner management companies, Approved Housing Bodies and registered charities (seai.ie). Its supports for landlords page says the Better Energy Homes grants are open to private and commercial landlords, and that you apply directly, as the homeowner would (SEAI's supports for landlords page).
| Home type | Windows grant | With two doors |
|---|---|---|
| Detached house | €4,000 | €5,600 |
| Semi-D or end of terrace | €3,000 | €4,600 |
| Mid-terrace | €1,800 | €3,400 |
| Apartment | €1,500 | €3,100 |

Do the rules change for a rented house?
No. The same rules apply (seai.ie):
- The home was built and occupied before 2011 and has an MPRN.
- You're replacing single-glazed or older double-glazed windows, or inefficient external doors.
- After the work, the BER advisory report shows Good or Very Good heat loss. An HLI below 2.3 meets it.
- An SEAI-registered contractor does the work.
- The grant offer comes before any work starts. No backdating.
- The windows grant is once per property.
The heat loss test is the one that catches rented homes. If the attic or walls need insulating first, those have their own grants, and since October 2026 the higher attic and cavity wall grants also reach landlords renting to HAP or RAS tenants (2026 timeline).
Can I claim the cost against rental income?
Yes, within limits. Revenue's retrofitting deduction lets a landlord deduct retrofit spending from rental income. SEAI's landlords page sets out the conditions (SEAI's supports for landlords page):
- Up to €10,000 per property.
- Only for work done under an approved SEAI retrofitting grant.
- The property is in Ireland, rented while the work is done, and the tenancy is registered with the RTB.
- You have a valid tax clearance certificate.
- The property stays rented for at least two years after the work.
SEAI's page still gives the end date as 31 December 2025 and a limit of two properties. Revenue says Finance Act 2025 extended the deduction to 31 December 2028 and raised the number of properties from two to three (Revenue eBrief 255/25, 31 December 2025). Ask your accountant how it applies to you. This isn't tax advice.
What about a holiday home?
SEAI lists holiday home owners among the people who can apply (seai.ie). The home still needs an MPRN, a build and occupation date before 2011, and the heat loss result after the work.
What does a landlord pay after the grant?
On SEAI's median costs for January to June 2026, new windows cost about €7,110 on a semi-D, so about €4,110 after the €3,000 grant, and €4,650 on a mid-terrace, about €2,850 after €1,800 (SEAI's median costs PDF). The PDF doesn't say if VAT is included. Every home type is on the cost page.
Things to sort before the contractor calls
- The tenant's agreement to access for the BER assessor and the fitters, with dates.
- The MPRN for the property, from the electricity bill.
- The current BER and advisory report, if there is one, to see the HLI.
- Whether you'll apply yourself or use a One Stop Shop.
We pass your request to one SEAI-registered contractor who covers the property's area. windowgrants.ie is not SEAI or a government body and does not award grants.
FAQ
Landlord questions
Can landlords get the SEAI window grant?
Yes. SEAI lists landlords among the people who can apply. The grant is the same: €1,500 to €4,000 for windows by home type, plus €800 a door, up to two.
Does the tenant have to agree?
SEAI's page sets no tenant condition for the grant. In practice the BER assessor and the fitters need to get in, so agree dates with the tenant first.
Can a landlord claim window costs against tax?
Revenue's retrofitting deduction covers work done under an approved SEAI grant, up to €10,000 per property, for a home rented during the work and registered with the RTB. Revenue says it now runs to 31 December 2028, for up to three properties. Check with your accountant.
Can I get the grant on a holiday home?
Yes. SEAI lists holiday home owners. The home still has to be built and occupied before 2011 and pass the heat loss test.
Is the grant bigger for landlords?
No. The windows and doors amounts are the same for everyone who can apply.
