Guide to SEAI Grants for Windows and Doors in 2025

March 13, 2025

Upgrading your windows and doors is one of the most effective ways to improve your home’s energy efficiency and reduce heating costs. Although there are no specific SEAI grants solely for windows and doors, Irish homeowners can benefit from a number of broader home retrofit schemes that include these essential upgrades.

This guide explains the available SEAI grants for window and door replacements in 2025, the benefits of making these energy-efficient upgrades, and what homeowners need to know when applying for grants.

Why Upgrade Your Windows and Doors?

Old, inefficient windows and doors can result in significant heat loss, which drives up energy bills and leaves your home feeling cold and drafty. Replacing them with modern, energy-efficient options can make your home more comfortable and lower your heating costs. According to SEAI, upgrading to double or triple-glazed windows can reduce your energy bills by up to €100 to €400 per year, depending on the type of window and your home’s insulation levels.

In addition to saving on energy costs, upgrading your windows and doors can also help your home meet SEAI’s Building Energy Rating (BER) standards, which are key to qualifying for grants under various home energy schemes.

SEAI Grant Schemes for Window and Door Upgrades in 2025

While there are no direct SEAI grants specifically for windows and doors, homeowners can receive funding for these upgrades as part of larger energy retrofitting programs. Here are the three main SEAI schemes that include support for window and door replacements:

1. The National Home Energy Upgrade Scheme (One-Stop Shop Scheme)
2. Better Energy Warmer Homes Scheme
3. Energy Efficiency Obligation Scheme (EEOS)

1. The National Home Energy Upgrade Scheme (One-Stop Shop Scheme)

The National Home Energy Upgrade Scheme, also known as the One-Stop Shop Scheme, is designed to help homeowners improve the overall energy efficiency of their homes. This scheme provides grants for multiple upgrades, including windows and doors, and aims to bring homes to a minimum BER rating of B2.

Grant Amounts for Windows and Doors:
Windows:
Apartment: €1,500
Mid-terrace house: €1,800
Semi-detached/end of terrace house: €3,000
Detached house: €4,000

Doors: €800 towards the installation of two external doors

Key Requirements:

• Your home must have been built before 2011.
• You must achieve a BER of B2 or better after the upgrade.
• You need to work with an SEAI-registered One-Stop Shop service provider, who will manage the entire process, including grant applications, assessments, and installation.

2. Better Energy Warmer Homes Scheme

This scheme is specifically designed for homeowners who are considered vulnerable or who receive qualifying social welfare payments. It offers fully funded energy efficiency upgrades, including window and door replacements, to improve the living conditions of homes that are often the least energy efficient.

Eligibility Criteria:

• The home must have been built and occupied before 2006.
• The home must have a BER rating of C, D, E, F, or G.
• The homeowner must be in receipt of certain social welfare payments.
• Priority is given to homes with a BER of E or lower, making this scheme highly beneficial for older homes that are in serious need of insulation and window upgrades. If you qualify, an SEAI contractor will visit your home to assess your needs, and the replacement windows and doors will be installed at no cost to you.

3. Energy Efficiency Obligation Scheme (EEOS)

The EEOS requires large energy suppliers to support homeowners in completing energy efficiency projects, including replacing windows and doors. Under this scheme, you can apply to your energy provider for assistance with energy-efficient upgrades.

Who Can Apply?

Homeowners can reach out to their current energy supplier to check if they offer support under the EEOS. Major energy suppliers such as Bord Gáis, Electric Ireland, Energia, and SSE Airtricity are obligated to provide help under this scheme. If your provider doesn’t offer assistance, you can apply to another obligated party for support.

How to Apply for SEAI Grants

If you’re planning to upgrade your windows and doors, it’s important to understand the application process for SEAI grants. Here’s a quick guide on how to apply:

• BER Assessment: Before applying for any grant, your home needs to have a current BER assessment. This rating will determine if your home qualifies for the grant and will also be used to measure improvements after the upgrades are completed.
• Select an SEAI-Registered Contractor: For the One-Stop Shop Scheme, you must use an SEAI-registered contractor to carry out the work. These contractors will manage the entire process, from applying for the grant to completing the installation.
• Application: You can apply for SEAI grants directly through the SEAI website or work with a registered contractor who will handle the application process for you.
• Installation and Final BER Assessment: Once the upgrades are complete, a final BER assessment will be carried out to ensure your home meets the energy efficiency standards required by SEAI.

The Benefits of Energy-Efficient Windows and Doors

Upgrading your windows and doors offers several key benefits:

• Reduced Energy Bills: Energy-efficient windows and doors can significantly lower your heating and cooling costs by improving your home’s insulation.
• Improved Comfort: New windows and doors prevent drafts and heat loss, creating a more comfortable living environment.
• Higher BER Rating: By improving your home’s energy efficiency, you’ll achieve a higher BER rating, which can increase the value of your property and make it more attractive to buyers.
• Environmental Impact: Reducing your home’s energy consumption is not only beneficial for your wallet but also for the environment, as it lowers your carbon footprint.
