SEAI Windows and Doors Grant Ireland

Government Grants for Energy-Efficient Windows & Doors

Homeowners in Ashbourne, Ratoath, Dunshaughlin, Dunboyne, and in fact all parts of Ireland can now upgrade their homes with high-performance windows and external doors with financial support from the Sustainable Energy Authority of Ireland (SEAI).

Through the Better Energy Homes programme, grants are available to help homeowners replace old, inefficient windows and doors with modern energy-efficient alternatives that we can supply and fit. These upgrades reduce heat loss, improve comfort, and lower energy bills.

Depending on your property type and the number of doors replaced, the total grant available can reach up to €5,600.

If your home has older single glazing or inefficient double glazing, upgrading your windows and doors could significantly improve your home's energy efficiency while benefiting from government funding.

Who Qualifies for the SEAI Windows and Doors Grant?

To qualify for funding under the Better Energy Homes Scheme, homeowners must meet certain eligibility criteria.

1. Property Age Requirement

Your home must have been:

Built and occupied before 2011

The grant targets older homes where energy upgrades will deliver the greatest improvement in energy performance.

2. Electricity Supply (MPRN)

The property must have a valid electricity supply.

Applicants must provide a Meter Point Reference Number (MPRN) when applying for the grant.

This number identifies your property’s electricity connection and confirms eligibility.

3. Eligible Applicants

The grant is available to several property owners, including:

Owner-occupiers
Landlords with rental properties
Owner management companies (OMCs)
Registered charities
Approved housing bodies
Owners of holiday homes

This ensures that most residential properties in Ireland can qualify, provided they meet the technical requirements.

Technical Requirements for Windows and Doors

To qualify for the grant, the replacement windows and doors must meet strict energy-efficiency standards, that Tudor Windows can supply and fit.

Window Performance Requirements

New windows installed under the scheme must achieve:

U-value of 1.4 W/m²K or better

The U-value measures how much heat passes through a window.

Lower values indicate better insulation and improved energy efficiency.

Most modern triple-glazed or high-performance double-glazed windows meet these standards.

Door Performance Requirements

External doors installed under the grant must also be highly insulated and energy efficient.

Typical qualifying doors include:

Composite doors
Insulated timber doors
High-performance uPVC doors
Aluminium insulated doors

These doors reduce heat loss and eliminate drafts around entry points.

Insulation Requirements Before Installing Windows & Doors

Before replacing windows or doors, your home must already have sufficient insulation levels.

This requirement ensures homeowners maximise energy savings from new glazing.

The home must have:

Adequate attic insulation, and
Adequate wall insulation

This can be verified through:

A BER Advisory Report, or
Evidence of previous SEAI insulation upgrades.

If insulation levels are not sufficient, homeowners may need to complete attic or wall insulation upgrades first before the windows and doors grant can be approved.

BER Requirements After the Upgrade

Once the windows and doors installation is completed, the property must receive a post-works Building Energy Rating (BER) assessment.

This assessment confirms that the upgrade improves the home’s energy efficiency.

The BER report is required before the **Sustainable Energy Authority of Ireland releases the grant payment.

Benefits of Replacing Your Windows and Doors

Upgrading your windows and doors provides both financial and comfort benefits.

Lower Energy Bills

Energy-efficient glazing reduces heat loss, lowering heating costs.

Improved Comfort

New windows and doors eliminate cold drafts and maintain consistent indoor temperatures.

Higher BER Rating

Energy upgrades improve your Building Energy Rating, making your home more energy efficient.

Increased Property Value

Homes with better energy efficiency are more attractive to buyers and renters.

Reduced Carbon Emissions

Better insulation helps reduce energy consumption and environmental impact.

Claim Income Tax back on the cost of your windows

The Home Renovation Incentive (HRI) is a relief from Income Tax (IT) for homeowners, landlords and local authority tenants. You can claim the HRI Tax Credit for repairs, renovations and improvements to your home or rental property.

To be eligible for HRI:

you must pay tax under Pay As You Earn (PAYE) or self-assessment - and be up to date.
your Local Property Tax (LPT) payments must be up to date (this does not apply if you are a local authority tenant)
the work to your property must be carried out by HRI qualifying contractors - e.g. Tudor Windows

The HRI is an online only scheme for homeowners and landlords. If you pay tax through PAYE, use myAccount to claim the HRI Tax Credit. If you pay tax through self-assessment, use Revenue Online Service (ROS) to claim the HRI Tax Credit.

If you are a local authority tenant you should contact your Revenue office.

Essentially, if you are paying your taxes, you may be entitled to the VAT (13.5%) or a portion of it back in the form of an income tax credit, when you are submitting your taxes.
