Are Window Replacement Grants available in Ireland?

Replacing windows can be one of the most effective ways to improve your home’s energy efficiency, comfort, and appearance. In Ireland, many homeowners are curious about Window Replacement Grant’s and whether grants are available to help with the cost of new windows.

The short answer is yes, but with a few important conditions. Grants for window replacement are offered through the Sustainable Energy Authority of Ireland (SEAI), but not as a standalone measure. They must be part of a broader home energy upgrade carried out through the One-Stop Shop scheme. This initiative supports homeowners looking to improve the overall energy performance of their home through multiple upgrade measures—windows and doors included.

Grant Funding for Window Upgrades

Under the One-Stop Shop scheme, homeowners can receive between €1,500 and €4,000 in grant funding for window upgrades, depending on the type of property. The scheme is designed to make the process as simple as possible: once you contact an SEAI-registered One-Stop Shop provider, they handle the assessment, grant application, and delivery of works.

It’s important to note that you can’t apply directly for just window replacement. Windows are not covered under SEAI’s individual grants for single upgrades like attic insulation or heating controls. This means that if you’re only looking to replace windows, and not planning a full retrofit, there isn’t a grant available through SEAI for that specific work.

How to qualify for Window Upgrade Grants (part of the One Stop Shop scheme)

To qualify for the One-Stop Shop scheme, your home must have been built and occupied before 2011 and have a Building Energy Rating (BER) of B3 or lower. The goal is that after the works, your home will achieve a BER of B2 or better. If you’re eligible, the One-Stop Shop provider will carry out a home energy assessment and provide a project plan, including a detailed breakdown of costs and grant funding.

Grant approval typically happens quickly—often within minutes once your application is submitted. You won’t have to pay the full cost of the works up front either. The grant is deducted directly from your invoice, so you only pay the balance.

For low-income or vulnerable households, there’s another option: the Warmer Homes Scheme. This fully funded programme offers deep energy upgrades, including window replacement, for eligible homeowners who receive certain welfare payments. Unlike the One-Stop Shop model, you can apply for this scheme directly through the SEAI website.

There’s also the Housing Aid for Older People scheme, which is run through your local authority. This grant can cover window and door replacement. It is means-tested and designed specifically for older homeowners or those with disabilities.

If you’re ready to start the process for a window upgrade as part of a wider retrofit. The best place to begin is by contacting an SEAI-registered One-Stop Shop. They’ll guide you through the application, help assess your home, and manage the grant on your behalf.
