What SEAI Grants Can I Get for My Home in 2026?

If you’re considering making your home warmer, more energy efficient and cheaper to run, SEAI home energy grants in 2026 can significantly reduce the cost of upgrading your property.

There are grants available towards a wide range of energy upgrades, including attic insulation, wall insulation, windows and doors, heat pumps, heating controls and solar panels.

However, understanding exactly which SEAI grants you can get and which upgrades are right for your home, isn’t always straightforward.

In this guide, we explain the main SEAI grants available in Ireland in 2026, how the different grant routes work and where to start if you’re considering a larger home energy upgrade.

What SEAI Grants Are Available in 2026?

The Sustainable Energy Authority of Ireland (SEAI) provides financial support to homeowners carrying out eligible energy-efficiency improvements.

In 2026, homeowners can access grants for measures including:

Attic and roof insulation
Cavity wall insulation
Internal wall insulation
External wall insulation
Energy-efficient windows
External doors
Heat pumps
Heating controls
Solar PV panels
Solar thermal systems
Floor insulation
Mechanical ventilation
Airtightness
Home Energy Assessments

The exact grants available to you will depend on factors including your property type, age of the home, existing BER, current insulation levels and the upgrades being carried out.

There are also different ways of accessing SEAI funding depending on whether you want to carry out one individual upgrade or undertake a more comprehensive retrofit.

SEAI Attic Insulation Grants 2026

Attic insulation is often one of the most cost-effective ways to improve the energy efficiency of an older home.

Because heat rises, a poorly insulated roof or attic can result in a significant amount of heat escaping from your property.

For standard homeowners, the 2026 attic insulation grants are:

Property Type	Grant
Apartment	€1,100
Mid-Terrace	€1,400
Semi-Detached / End of Terrace	€1,500
Detached	€2,000

Higher attic insulation grants are available for qualifying first-time buyers and certain homeowners receiving qualifying welfare payments.

For example, an eligible first-time buyer of a detached property may qualify for up to €2,500 towards attic insulation.

Improving attic insulation can help your home retain heat for longer, reduce heating demand and contribute towards improving your BER.

SEAI Wall Insulation Grants 2026

The right type of wall insulation depends on how your home was constructed.

Depending on the property, this could include:

Cavity Wall Insulation

If your home has suitable cavity walls, insulation can be pumped into the cavity between the inner and outer walls.

This can be one of the least disruptive ways of improving the thermal performance of a suitable property.

Internal Wall Insulation

Also known as dry lining, this involves applying insulation to the internal surfaces of external walls.

It can be an option for properties where cavity insulation isn’t suitable.

External Wall Insulation

External wall insulation — sometimes called external insulation or a home energy wrap — involves installing insulation around the outside of the property and applying a new external finish.

It can substantially improve the thermal performance of an older property while also changing the external appearance of the home.

SEAI grant values vary depending on the type of insulation and property.

For example, under the One Stop Shop route, external wall insulation grant support can reach €6,000 for a detached house, subject to eligibility.

SEAI Windows Grant 2026

One of the biggest developments for homeowners in 2026 is the availability of grant support for upgrading windows.

Replacing older windows can reduce draughts and heat loss while improving comfort throughout the home.

Current SEAI window grants are:

Property Type	Maximum Grant
Apartment	€1,500
Mid-Terrace	€1,800
Semi-Detached / End of Terrace	€3,000
Detached	€4,000

There are important eligibility requirements.

For example, the home generally needs to have been built and occupied before 2011, and the attic and walls must meet SEAI’s required insulation standards.

The replacement windows must also meet the required energy-performance specification.

This means it is worth looking at your home as a whole rather than automatically replacing windows as the first energy upgrade.

SEAI External Door Grants 2026

Grant funding is also available towards replacing inefficient external doors.

The current grant is:

€800 per external door, up to a maximum of two doors.

That means eligible homeowners replacing two qualifying external doors could receive up to €1,600 in grant support.

Windows and doors can be upgraded together, subject to the relevant eligibility and technical requirements.

SEAI Heat Pump Grants 2026

A heat pump can provide highly efficient renewable heating by extracting heat from the outside air or ground and using it to heat your home.

However, installing a heat pump isn’t simply a case of replacing your existing boiler.

Your property needs to retain heat effectively for a heat pump to perform efficiently.

This is why insulation, airtightness, windows and other fabric improvements may need to be considered before or alongside a heat pump installation.

SEAI support is available towards eligible heat pump systems, with the amount depending on the property and route used.

Under the One Stop Shop scheme, qualifying projects can also potentially receive support towards measures associated with the heat pump, including the central heating system and heating controls.

A professional assessment of the property is therefore particularly important when considering a heat pump.

SEAI Solar Panel Grant 2026

Solar PV panels generate renewable electricity from daylight, helping reduce the amount of electricity your household needs to purchase from the grid.

The SEAI Solar PV grant currently provides:

€700 per kWp up to 2kWp
€1,400 for a 2kWp system
€1,600 for a 3kWp system
€1,800 for a 4kWp system

The maximum Solar PV grant is currently €1,800.

The right solar PV system size will depend on factors including your electricity consumption, available roof space, roof orientation and how you expect your energy use to change in the future.

What Is an SEAI One Stop Shop?

If you’re considering several energy upgrades at the same time, you may want to use an SEAI registered One Stop Shop.

Rather than organising separate contractors, grant applications and stages of work yourself, a One Stop Shop manages the home energy upgrade process on your behalf.

This can include:

Initial Home Energy Assessment
Identifying suitable energy upgrades
SEAI grant applications
Project management
Contractor coordination
Retrofit works
Quality assurance
Post-works BER assessment

Another major advantage is how the grant funding is handled.

When you undertake qualifying works through a One Stop Shop, the applicable SEAI grants are deducted upfront from the cost of the project.

This means you don’t normally have to fund the grant portion of the eligible works yourself and then wait to claim it back.

What BER Do I Need to Achieve Through a One Stop Shop?

For most homes undertaking a complete energy upgrade through the National Home Energy Upgrade Scheme, the project must bring the property to at least the required B BER level, subject to the applicable scheme requirements.

Many older Irish homes may require several improvements to achieve this.

For example, a retrofit could potentially combine:

Attic insulation + wall insulation + windows and doors + heat pump + ventilation + Solar PV

The exact combination will be different for every property.

A house that already has good insulation may require a very different package of works from an older property that has had few energy upgrades.

Individual SEAI Grants vs One Stop Shop

Which option is better depends largely on what you want to achieve.

Individual Grants

Individual SEAI grants can make sense if you’re carrying out one or two upgrades and want to manage the process yourself.

For example, you might simply want to:

Insulate your attic
Install cavity wall insulation
Upgrade windows
Install Solar PV

You arrange the contractors and manage the relevant grant process.

One Stop Shop

The One Stop Shop route is designed for homeowners considering a more comprehensive energy upgrade.

Instead of treating each measure separately, the house is assessed as a whole.

This can be particularly useful if you’re considering several measures and want to understand how they work together.

Can I Combine Multiple SEAI Grants?

Yes.

One of the major advantages of undertaking a comprehensive home energy upgrade is that multiple eligible grants can potentially be combined within the same project.

For example, an eligible retrofit could potentially receive grant support towards:

Attic insulation
Wall insulation
Windows
External doors
Heat pump
Heating controls
Solar PV
Ventilation
Airtightness
Home Energy Assessment
Project management

This can result in significant overall grant support, although the actual amount will depend on the property and measures required.

Is My House Eligible for SEAI Grants?

Eligibility varies depending on the grant.

The age of your property is particularly important.

For example, many insulation and window/door supports apply to homes built and occupied before the relevant SEAI cut-off date, while heat pump eligibility has different requirements.

Previous grants claimed against the property can also affect eligibility.

Rather than assuming that every advertised grant applies to your house, it’s important to establish:

Which measures your property actually requires
Which grants the property qualifies for
The cost of the recommended works
The expected BER improvement
Your estimated cost after applicable grants

What If I Don’t Know My Current BER?

Don’t worry if you don’t know your current BER rating.

A BER is useful when considering a retrofit because it provides information about your property’s current energy performance.

For homeowners considering a larger retrofit through a One Stop Shop, a Home Energy Assessment can provide much more detail about the measures that may be appropriate for the property.

This helps create a roadmap for improving the home rather than choosing upgrades in isolation.

Are There Extra Supports for First-Time Buyers in 2026?

Yes.

One of the changes introduced for 2026 is increased support for eligible first-time buyers purchasing existing homes.

For example, qualifying first-time buyers can receive enhanced attic insulation grants.

To qualify for the higher first-time buyer attic grant, the existing home must have been built and occupied on or before 31 December 2010 and purchased by the eligible first-time buyer on or after 1 January 2025.

What About the Warmer Homes Scheme?

SEAI also operates a fully funded energy upgrade scheme for eligible homeowners receiving certain qualifying social welfare payments.

This is separate from the standard One Stop Shop process.

Eligibility criteria apply, and an SEAI surveyor determines which measures are suitable for the property.

If you believe you may qualify for the Warmer Homes Scheme, you should contact SEAI directly for information on applying through that programme.

Can Traditional or Older Homes Get SEAI Grants?

Owners of traditional properties may also have options.

SEAI is operating a Traditional Homes Pilot, designed for traditionally constructed properties that may require different materials and retrofit approaches from modern homes.

Eligible projects can potentially include:

Roof, wall and floor insulation
Windows and doors
Ventilation
Heat pumps
Solar PV
Solar thermal

Traditional buildings require particularly careful assessment because inappropriate retrofit measures can create moisture and ventilation problems.

How Much Will My Home Energy Upgrade Cost After Grants?

This is ultimately the question most homeowners want answered.

Unfortunately, there isn’t one figure that applies to every property.

Two seemingly similar semi-detached homes could require very different packages of work depending on their age, construction, existing insulation, windows, heating system and current BER.

That’s why House2Home has developed an online Home Energy Upgrade Cost Calculator.

You can enter information about your property and select the upgrades you’re considering to receive an initial indicative estimate of the project cost and applicable grant support.
