New SEAI Grants Released for Windows and Doors in Ireland (2026 Guide)

Homeowners across Ireland now have a fantastic opportunity to upgrade

their homes thanks to new and enhanced SEAI grants for energy-efficient windows and doors, introduced as part of the Government’s National Residential Retrofit Plan.

If you’ve been thinking about replacing old windows or upgrading your front door, 2026 may be the best time to do it.

What Is the New SEAI Windows & Doors Grant?

The Sustainable Energy Authority of Ireland (SEAI) has introduced a standalone grant specifically for windows and doors, making energy upgrades more accessible than ever.

Previously, homeowners could only receive funding for windows and doors as part of a full deep retrofit project. Now, you can upgrade these elements individually — without committing to a full home renovation.

This change allows more homeowners to improve comfort, energy efficiency, and security at a lower upfront cost.

How Much Can You Receive?

Grant amounts depend on your property type and the number of doors replaced.

Window Grants

• Apartment: up to €1,500

• Mid-terrace house: up to €1,800

• Semi-detached / end-terrace: up to €3,000

• Detached house: up to €4,000

Door Grants

• €800 per external door

• Maximum of two doors (€1,600 total)

In some cases, homeowners can receive up to €5,600 combined support for windows and doors upgrades.

Who Is Eligible?

To qualify for the grant, your home must:

• Be built and occupied before 2011

• Replace existing inefficient windows or external doors

• Install high-performance products meeting energy standards (U-value 1.4 W/m²K or better)

• Have adequate attic and wall insulation

• Use an SEAI-registered contractor

A post-works BER (Building Energy Rating) assessment is also required after installation.

Why the Government Introduced This Grant

Older windows and doors can account for a significant portion of heat loss in Irish homes, leading to higher energy bills and reduced comfort.

The new grant aims to:

• Reduce heat loss and energy costs

• Improve home comfort and warmth

• Support Ireland’s climate targets

• Help homes become heat-pump ready

Energy upgrades like these are considered one of the most effective ways to make homes warmer and cheaper to heat.

When Can You Apply?

The scheme applies to qualifying window and door upgrades ordered or started from 27 January 2026 onward, provided all SEAI requirements are met.

Applications are completed online through the SEAI grant system after selecting an approved contractor.

Why Now Is the Best Time to Upgrade

With rising energy costs and increased government support, upgrading your windows and doors now offers multiple benefits:

✅ Lower heating bills

✅ Improved home comfort

✅ Better energy rating (BER)

✅ Increased property value

✅ Enhanced security and appearance
