What Is the SEAI Windows & Doors Grant?

The SEAI Home Energy Grant scheme supports homeowners replacing old, inefficient windows and external doors with modern, high-performance, thermally efficient systems.

The aim of the scheme is to:

1. Improve home energy efficiency
2. Reduce heat loss
3. Improve BER rating
4. Lower energy bills
5. Reduce carbon emissions

The scheme has proven hugely popular since opening on 2 March 2026. For live figures on applications, eligibility and values, see our SEAI windows and doors grant statistics.

How Much Can You Claim?

Since 2 March 2026, the SEAI Windows & Doors Grant is available as a standalone measure — you no longer need a full One Stop Shop retrofit to qualify. The window grant is tiered by home type:

Apartment: up to €1,500 for windows
Mid-terrace house: up to €1,800 for windows
Semi-detached house: up to €3,000 for windows
Detached house: up to €4,000 for windows
External doors: €800 per door, maximum two doors (€1,600 total)

The maximum combined support is €5,600 (a detached home claiming windows plus two doors). Grant values and eligibility are determined solely by SEAI. Uptake has been rapid: SEAI received more than 7,000 applications for the windows and doors grant in its first month. For the full picture on BER ratings, retrofit progress and grant uptake, see our Irish home energy efficiency statistics.
