SEAI grants for home energy upgrades in 2026
Plain-English summary
SEAI provides financial support for qualifying home-energy improvements in Ireland, including insulation, windows and doors, heat pumps, heating controls, solar PV and other retrofit measures.
Most homeowners will meet SEAI grants through one of three routes: Individual Energy Upgrade Grants, a One Stop Shop or Complete Home Energy Upgrade, or fully funded upgrades through the Warmer Homes Scheme for qualifying households.
Key facts
- Amounts shown below are maximum current supports and may depend on property type, upgrade type and eligibility.
- Under the individual-grant route, you generally need grant approval before qualifying works begin.
- Different SEAI grants use different property and technical rules, so do not rely on one universal eligibility rule.

Which SEAI route is right for you?
Individual grants
Best for homeowners or landlords carrying out one or several upgrades separately, such as attic insulation, wall insulation, windows and doors, heat pumps, heating controls, solar PV or solar thermal.

Attic insulation
SEAI lists fixed attic insulation amounts by dwelling type: detached EUR2,000, semi-detached or end terrace EUR1,500, mid-terrace EUR1,400 and apartments EUR1,100. Eligible first-time buyers or qualifying welfare recipients can receive higher attic support: detached EUR2,500, semi-detached or end terrace EUR1,900, mid-terrace EUR1,800 and apartments EUR1,400.
The home needs an MPRN and must meet SEAI property rules. SEAI also says the attic grant is not open where the MPRN has already received previous attic insulation funding. You must use an SEAI-registered contractor.
Full attic insulation grant guide
Wall insulation
Wall insulation includes cavity wall insulation, internal insulation or dry lining, and external wall insulation or wrap. SEAI grant amounts vary significantly by method and dwelling type, with the highest standard amount currently shown for external wall insulation on a detached house.
SEAI says wall insulation generally requires a whole-surface solution, and some homes that previously received wall insulation support may now apply for a second wall measure under specific rules.
Windows and doors
SEAI lists window grant amounts by dwelling type: apartment EUR1,500, mid-terrace EUR1,800, semi-detached or end terrace EUR3,000 and detached EUR4,000. External doors are listed at EUR800 per door, with a maximum of two qualifying doors.
This is not a simple "replace any window and get the maximum" grant. SEAI says the home must meet specific property, insulation, U-value and post-works BER or Heat Loss Indicator requirements. Existing attic and wall insulation can affect whether the windows and doors support is available.
Heat pumps
SEAI describes the heat pump system grant as a package that can reach up to EUR12,500 depending on dwelling type, system and qualifying measures. The package can include heat pump support, central heating system upgrade support where required, and a Renewable Heat Bonus where a fossil-fuel or electric storage heating system is being replaced.
Heat pump suitability is technical. Check assessment requirements, heat-loss requirements, heating distribution, hot-water setup and contractor requirements before assuming the grant applies.
Solar PV
SEAI lists solar PV support as EUR700 per kWp up to 2kWp, then EUR200 for every additional kWp up to 4kWp, capped at EUR1,800. SEAI says the home needs an MPRN, must have been built and occupied before 2021, and must not have previous solar PV funding at that MPRN.
Heating controls
SEAI lists heating controls support up to EUR700. This is aimed at improving control of heating and hot water schedules. It may be relevant where a full heating-system change is not the right first step.
Solar water heating
SEAI lists solar water heating support up to EUR1,200 for eligible solar thermal hot-water systems.
Can you get an SEAI grant?
SEAI grant eligibility can depend on the grant type, year the home was built and occupied, dwelling type, previous grants, existing insulation, BER or technical performance, heating system, contractor, MPRN and property ownership or use.
You may need
- Your MPRN.
- Your property type and year built or occupied.
- Details of your existing heating system and insulation.
- A contractor quotation.
- An SEAI-registered contractor for the relevant work.
- A technical assessment or self-declaration for certain upgrades.
Do not start work before grant approval
Under the individual-grant route, applicants generally need to apply, receive and accept the grant offer, and then begin qualifying works. SEAI says grant applications for works done outside the grant-offer period are not eligible for payment.
How to apply for an SEAI grant
- Decide which upgrades you want.
- Check your property's eligibility for that specific upgrade.
- Get quotes from appropriate SEAI-registered contractors.
- Apply for the grant through the required SEAI route.
- Wait for grant approval before starting qualifying works.
- Complete the work within the applicable grant-offer period.
- Complete BER or documentation requirements where applicable.
- Submit the required paperwork and receive the approved grant payment.
Does SEAI give grants for new boilers?
SEAI says it does not currently provide grants for new or replacement fossil-fuel boilers such as gas or oil boilers. Relevant alternatives may include heating controls, heat pump support, insulation or other energy-efficiency upgrades.
This matters because "boiler grant" searches often mix fossil-fuel boiler replacement with low-carbon heating support. Check the specific SEAI page before planning work.
First-time buyers and SEAI grants
SEAI has enhanced attic insulation support for qualifying first-time buyers of existing homes. SEAI states the buyer must own and live in the home, the home must have been built and occupied on or before 31 December 2010, and the property must have been purchased on or after 1 January 2025.
This is not a universal "first-time buyer SEAI grant". The enhanced first-time buyer support described by SEAI applies to the attic insulation measure.
Low-income and welfare support
There are two separate ideas to keep clear. First, enhanced individual grant rates may apply to qualifying households for specific upgrades such as attic insulation and cavity wall insulation. Second, the Warmer Homes Scheme is a fully funded route for qualifying owner-occupiers receiving certain social welfare payments.
Do not assume qualifying for one route automatically means you qualify for the other. Check the SEAI Warmer Homes page and the individual grant page for the exact measure.
FAQ
What SEAI grants are available in 2026?
SEAI lists individual grants for measures including attic insulation, wall insulation, windows and doors, heat pump systems, heating controls, solar PV and solar water heating. It also offers One Stop Shop and Warmer Homes routes.
How much can I get from an SEAI grant?
It depends on the measure, dwelling type and eligibility. Current maximums include up to EUR1,800 for solar PV, up to EUR4,000 for windows, and potential heat pump package support up to EUR12,500, but you must verify the exact current amount with SEAI.
Can I get an SEAI grant for windows?
Yes, SEAI has a windows and doors grant, but technical and insulation requirements apply. The maximum window grant depends on dwelling type.
Can I get an SEAI grant for a new boiler?
SEAI says it does not give grants for new or replacement fossil-fuel boilers such as gas or oil boilers. Heating controls or heat pump support may be relevant alternatives.
Can landlords get SEAI grants?
SEAI says Better Energy Homes grants are available to private and commercial landlords, but each grant has its own rules and application requirements.
Can I apply after the work has started?
For individual grants, SEAI says you must apply and accept the grant offer before beginning works. Works outside the grant-offer period are not eligible for payment.
How long is an SEAI grant offer valid?
SEAI support guidance says grant offers are valid for eight months. Check the current grant-offer letter and SEAI guidance for the measure you are applying for.
Do I need a BER for an SEAI grant?
Many SEAI grant routes involve BER or technical documentation. SEAI says all attic grant applicants must carry out a post-works BER assessment before drawing down that grant, and windows and doors also require a post-works BER.
Can first-time buyers get higher SEAI grants?
SEAI describes higher attic insulation support for qualifying first-time buyers of existing homes. It is not a universal higher grant across every SEAI measure.
Can I claim more than one SEAI grant?
SEAI individual grants can be used for one or multiple measures, but previous grants, measure-specific restrictions and technical rules can affect eligibility.
