Upgrade Grants

What this page covers

This page brings together current SEAI support for home energy upgrades in one place: the amounts on offer for individual measures, how an individual grant differs from a One Stop Shop project or the fully funded Warmer Homes Scheme, who can apply, what your property needs to qualify, and what actually happens when you apply. Upgrader.ie is not SEAI, a Government body or a grant administrator, and we cannot determine your eligibility or approve a grant. Treat every figure here as a starting point, and confirm your own current entitlement directly with SEAI before you commit to work.

Before you read on

Grant amounts and eligibility information on this page were checked on 7 October 2026. Grant approval is normally required before work starts, on both the individual grant and One Stop Shop routes. Eligibility differs from measure to measure, so a rule that applies to attic insulation will not necessarily apply to a heat pump or a window. Always confirm the current amount and your own eligibility with SEAI before requesting quotations or booking work.

New from 6 October 2026

SEAI has added a €600 battery grant and a €2,000 Boiler Scrappage Grant within the heat pump grant, opened solar PV and solar thermal grants to homes built and occupied before 2025, and added solar PV and a battery as standard under the Warmer Homes Scheme. These are SEAI scheme changes, not Budget 2027 measures. See our guide to new SEAI grants from October 2026 for what changed and who it applies to.

Choose your route

Individual grants, a One Stop Shop, or the Warmer Homes Scheme

SEAI support for homeowners comes through three distinct routes, and they suit different people for different reasons. None of the three is universally better. The right one depends on how many measures you are planning, how much you want to manage yourself, and whether you qualify for fully funded support.

Grant route comparison
What to know Individual grants One Stop Shop Warmer Homes Scheme
Who manages the application You do, working directly with SEAI and your chosen contractor An SEAI registered One Stop Shop provider manages the grant paperwork on your behalf SEAI manages the whole project for eligible homeowners
Who arranges the contractors You do, choosing an SEAI registered contractor for each measure The One Stop Shop provider, usually as a single combined project SEAI, through its own contracted installers
When the grant is applied You generally pay the contractor in full, then SEAI pays the grant to you afterwards The grant is usually deducted from the quoted price upfront, so you pay only the balance There is normally nothing to pay, since the works are fully funded
Minimum BER outcome required No fixed post works BER target, though a post works BER assessment is required for most measures Yes. Current SEAI guidance requires a minimum post works BER of B, alongside other qualifying criteria Not a fixed condition of eligibility, though a BER assessment is included
Most suitable for Homeowners planning one or a small number of measures who are comfortable managing contractors themselves Homeowners planning a larger, whole home upgrade who want it managed as a single project Homeowners who own and live in a home built and occupied before 2006 and receive a qualifying welfare payment
Check the current One Stop Shop conditions

The minimum post works BER and any energy improvement requirement for a One Stop Shop project can change and can depend on whether a heat pump is included in the works. Confirm the exact current requirement for your own project with an SEAI registered One Stop Shop provider or with SEAI directly.

Grant amounts

Current individual grant amounts

The figures below reflect current SEAI guidance for the individual grant route. Every amount shown is a maximum, not a guaranteed payment, and the actual support depends on the measure, your dwelling type and your own eligibility. Scheme details can change, so confirm the current amount directly with SEAI before assuming it applies to your project.

Attic insulation

Standard individual grant, by dwelling type:

  • Detached house: up to €2,000
  • Semi detached or end of terrace: up to €1,500
  • Mid terrace: up to €1,400
  • Apartment: up to €1,100

A higher fixed grant of up to €2,500 currently applies for qualifying first time buyers of an existing home and for homeowners receiving qualifying welfare payments, though the exact enhanced amount varies by dwelling type in each case. Rafter level insulation, sometimes used where a roof space is converted or has limited access, is generally assessed and grant supported under this same attic insulation measure rather than as a separate grant, so confirm which approach your surveyor recommends and how SEAI treats it for your property. If your attic already has some insulation, our guide to topping up existing attic insulation explains what to check before deciding whether more is needed.

Cavity wall insulation

Standard individual grant, by dwelling type:

  • Detached: up to €1,800
  • Semi detached or end of terrace: up to €1,300
  • Mid terrace: up to €850
  • Apartment: up to €700

Homeowners receiving qualifying welfare payments can currently access a higher grant of up to €2,300 for a detached home, with different fixed amounts for other dwelling types.

Internal wall insulation

  • Detached: up to €4,500
  • Semi detached or end of terrace: up to €3,500
  • Mid terrace: up to €2,000
  • Apartment: up to €1,500

External wall insulation

Often described by its maximum amount, but the maximum only applies to a detached home:

  • Detached: up to €8,000
  • Semi detached or end of terrace: up to €6,000
  • Mid terrace: up to €3,500
  • Apartment: up to €3,000

All three wall insulation grants currently require the home to have all external walls fully insulated, not just one or two. See Previous grants below for how a second wall measure is treated.

If you are weighing up which wall grant fits your home, our guide to choosing between internal and external wall insulation covers disruption, floor area and appearance, and our guide to insulating a solid wall home explains what changes for older solid wall properties. When you are ready to contact companies, our directory lists a selection of SEAI registered insulation companies.

Windows and external doors

Windows, by dwelling type:

  • Detached house: up to €4,000
  • Semi detached or end of terrace: up to €3,000
  • Mid terrace: up to €1,800
  • Apartment: up to €1,500

External doors are supported at up to €800 per door, to a maximum of two doors, so the €1,600 headline figure quoted for doors is a maximum for two doors, not a single flat payment. Both grants currently require the home to already have adequate attic and wall insulation in place, which SEAI accepts can be shown through a previous SEAI insulation grant, a BER Advisory Report rating the attic and walls as Good or Very Good, or an assessment by a BER assessor. This is a genuine qualifying condition, not a formality, and you do not need to replace every window in the home to apply. Our directory lists a selection of SEAI registered window and door companies.

Heat pump systems

Since 6 October 2026, the Heat Pump System grant is made up of three separately capped parts rather than one automatic payment:

  • Heat pump system: up to €10,500
  • Central heating upgrade, such as radiators, pipework or underfloor heating: up to €2,000
  • Boiler Scrappage Grant, where an oil, gas or solid fuel system or electric storage heating is removed: €2,000

Together these give a combined maximum of up to €14,500, but only where every part applies to your home and installation. Treat €14,500 as a ceiling for a house, not an entitlement. For an apartment, the qualifying maximum is up to €11,500. Where an existing heat pump is being replaced and the extra decarbonisation grants do not apply, support is up to €6,500 for a house and €4,500 for an apartment. The home must still have been built and occupied before 2021. Our directory lists a selection of SEAI registered heat pump companies.

Central heating upgrade support and the boiler scrappage grant

These are not standalone grants. They are components of the wider heat pump system grant above, and SEAI says eligibility for each depends on your contractor's installation design. The Boiler Scrappage Grant is not a grant for a new boiler: SEAI does not fund new fossil fuel boilers, and the €2,000 only applies where an eligible heat pump replaces the existing system. Ask your installer and SEAI which components apply to your specific project before assuming the full maximum applies.

Air to air heat pumps

Support for a qualifying air to air heat pump is up to €9,500. Air to air systems do not heat water or serve radiators, so the central heating upgrade works that apply to water based systems are not part of this type of installation. Treat the figure as a maximum, and confirm with your installer and SEAI what applies to your own project.

Heating controls

A flat grant of up to €700 currently applies across dwelling types, generally covering items such as a room thermostat, thermostatic radiator valves, a time clock or programmer, and zone controls.

Solar PV

Calculated at €700 per kWp for the first 2kWp of a system, then €200 per kWp up to a 4kWp limit, giving a maximum grant of €1,800, so a system under 4kWp receives less. Since 6 October 2026, the home must have been built and occupied before 2025, where the previous cut off was before 2021. Use our Solar Cost and Payback Calculator to see how this grant applies to an indicative cost range for your own system size. Our directory lists a selection of SEAI registered solar PV companies.

Home battery storage

A flat rate Battery Energy Storage System Grant of €600 has been available since 6 October 2026 for a home battery of 5kWh or larger, in a home built and occupied before 2025. You must receive a grant offer before the battery is installed, the installer must be an SEAI registered Solar PV contractor, and the grant is not available where a battery has already been funded at the same MPRN. You can apply for a battery together with solar PV or separately. See our guide to the SEAI battery storage grant for the full conditions.

Solar water heating

A flat grant of up to €1,200 currently applies, regardless of dwelling type. SEAI's October 2026 changes extended solar thermal eligibility to homes built and occupied before 2025, in line with solar PV.

The grant process, in short

For individual grants, approval must generally be obtained before work begins, the work must be carried out by an SEAI registered contractor registered for that type of work, and a post works Building Energy Rating assessment is normally required before the grant is paid. Always confirm current terms directly with SEAI before proceeding.

Who can apply

Who can apply for a home energy upgrade grant?

Eligibility for individual grants and One Stop Shop support is not limited to owner occupiers, though the position varies for some categories of applicant.

  • Owner occupiers. The core group most SEAI individual and One Stop Shop grants are designed for.
  • Private and commercial landlords. Eligible for individual grants and One Stop Shop support on rental properties, alongside separate supports such as the Home Energy Upgrade Loan Scheme for up to three properties. Since 6 October 2026, enhanced grants also apply to qualifying homes let under HAP, RAS and RASP tenancies, including attic insulation support of €1,400 to €2,500 and cavity wall insulation support of €900 to €2,300, depending on the property type.
  • First time buyers of an existing home. Can currently access a higher fixed attic insulation grant, subject to purchase date and other conditions. This enhanced rate does not extend to every other measure.
  • Apartment owners and owner management companies. Individual apartments can qualify for lower, apartment specific grant amounts. Where a measure affects shared structure or common areas, such as attic insulation above a block, the owner management company generally needs to be involved and consent to the work.
  • Holiday homes, companies, charities and Approved Housing Bodies. Generally eligible for the main individual grants, subject to the same property level conditions as any other applicant. Approved Housing Bodies also have access to dedicated retrofit supports outside the scope of this page.
  • Households receiving qualifying welfare payments. Can access higher fixed grant amounts for some individual measures, including up to €9,000 towards Solar PV of up to 4kWp and a 5kWh battery, and more generous attic and cavity wall support, since 6 October 2026, and may also qualify for the fully funded Warmer Homes Scheme instead, which now includes solar PV and a battery as standard. Using the enhanced individual grant rate does not affect your place on the Warmer Homes Scheme waiting list.
Confirm your own category

These categories are not exhaustive and conditions can differ within each one. If your situation does not clearly fit owner occupier, contact SEAI directly rather than assuming a general description here applies to you.

Property eligibility

Does your property qualify?

Eligibility dates and requirements differ between measures, so do not assume one date applies to every grant on this page.

  • Build and occupation date. Insulation, windows, doors and heating controls grants currently require the home to have been built and occupied before 2011. Heat pump grants require the home to have been built and occupied before 2021. Since 6 October 2026, solar PV, solar thermal and battery grants require the home to have been built and occupied before 2025. These are different thresholds, not the same rule stated three times.
  • MPRN. Your home needs a valid MPRN, the reference number for your electricity connection shown on your bill, and it must stay unchanged throughout the application.
  • Previous grants. A previous SEAI grant, or support received under the Energy Efficiency Obligation Scheme, can affect eligibility for the same or a related measure. Wall insulation has its own rule on applying for a second measure, covered under Previous grants below. Declare any previous energy upgrade support when you apply.
  • Heat pump technical assessment. A home generally needs a Heat Loss Indicator low enough to qualify, confirmed either through a valid BER or a Technical Assessment carried out by an SEAI registered Technical Advisor. See our Heat Pumps guide for how this figure is worked out.
  • Windows and doors fabric requirement. As set out above, your attic and wall insulation must already meet a satisfactory standard before a standalone windows or doors grant applies.
  • Traditional homes. Traditionally constructed homes, generally solid masonry built before 1940 without a cavity, can still access individual grants for attic insulation, heating controls, solar PV and solar water heating through the standard route. Wall insulation for these homes is generally handled separately through the Traditional Homes Pilot, which uses products suited to solid wall construction and is accessed through a participating One Stop Shop rather than a standalone wall insulation grant.
  • Island homes. Homeowners on a defined list of offshore islands may qualify for additional grant support on top of the standard amounts. We have not quoted a figure here since it was not one we could confirm consistently. Check current island support directly with SEAI.
  • BER requirements. A post works BER assessment is required before payment for most individual measures. A One Stop Shop project currently carries its own minimum post works BER requirement, covered under Choose your route above. Since 24 May 2026, BER certificates use a simplified scale of A0, A, B, C, D, E, F and G, without sub-bands such as B2, so the One Stop Shop requirement that was previously B2 is now B.
How it works

How the application works, step by step

The exact steps differ slightly between routes, but most individual grant and One Stop Shop projects follow a broadly similar sequence.

1

Decide which upgrade is appropriate

Work out which measure, or combination of measures, actually addresses your home's needs before requesting quotations.

2

Check property and applicant eligibility

Confirm your build and occupation date, MPRN and any previous grant history against the specific measure you want.

3

Choose the correct grant route

Decide between an individual grant, a One Stop Shop, or check whether you qualify for the Warmer Homes Scheme instead.

4

Select an SEAI registered contractor or One Stop Shop

Only work carried out by a contractor registered with SEAI for that type of work qualifies for support.

5

Obtain grant approval before work begins

Apply and receive a grant offer from SEAI before any work starts. Starting early is one of the most common reasons a grant is refused.

6

Complete the work to the required standard

The contractor carries out the work, generally within the validity period of your grant offer.

7

Complete declarations and technical documentation

This can include a post works BER assessment, installer declarations, and technical documentation for measures such as heat pumps.

8

Submit your claim or receive your One Stop Shop discount

On an individual grant, you submit your payment claim to SEAI once the work and paperwork are complete. On a One Stop Shop project, the grant was already deducted from the price you paid.

Common mistakes

Mistakes that can affect a grant

Most grant refusals and delays we have seen discussed come down to a small number of avoidable issues.

Starting work before approval. Work carried out before your grant offer issues generally does not qualify, even if it is otherwise eligible.
Assuming the headline maximum applies to every home. Most grant amounts vary by dwelling type, and the largest figure quoted is usually the detached house rate, not a universal amount.
Using a contractor who is not registered for that specific measure. Registration is measure specific, so a contractor registered for insulation is not automatically registered for heat pumps.
Missing the grant offer timeframe. An individual grant offer does not stay valid indefinitely, so plan the works and completion around the timeframe stated on your own offer letter.
Failing to account for previous grant support. Not declaring a previous grant can cause problems later, even where the new application would otherwise have been allowed.
Assuming windows or doors qualify without meeting the fabric rule. The existing attic and wall insulation requirement is checked before the windows or doors grant is approved, not after work is done.
Treating heat pump support as one automatic payment. The maximum is made up of separate parts, and not every project qualifies for all of them.
Confusing an individual grant with a One Stop Shop grant. Payment timing, BER requirements and who manages the paperwork differ between the two, as set out above.
Assuming a One Stop Shop project will hit its post works BER target automatically. Current SEAI guidance sets a minimum post works BER of B for a One Stop Shop project, and this is checked, not assumed, so confirm it with your provider before committing to the works.
Not keeping invoices, declarations and certificates. Payment claims and any future property sale can depend on being able to show what was done, by whom, and when.
Previous grants

What if the home received a grant before?

A previous grant does not always rule out further support. The answer depends on the specific measure previously funded and the measure you are now applying for. For wall insulation, homeowners who previously received support for one wall insulation measure may now be able to apply for a second wall measure, subject to the current SEAI scheme conditions. This is not automatic, and does not mean every home that received a wall insulation grant in the past will qualify for another one now, so confirm your own position directly with SEAI before assuming a second measure applies to you.

For other measures, such as attic insulation, windows, doors or a heat pump, the position depends on what exactly was previously funded and under which scheme, including support received under the Energy Efficiency Obligation Scheme. Declare any previous energy upgrade support when you apply, and ask SEAI directly whether it affects the specific grant you now want.

Budget 2027

Did Budget 2027 affect these grants?

Budget 2027 was published on Tuesday 6 October 2026. It did not change the SEAI grant amounts or eligibility rules on this page. The new battery grant, the Boiler Scrappage Grant and the wider solar eligibility opened on the same day, but they were announced separately by the Department of Climate, Energy and the Environment at the end of September 2026, as part of a package developed through the National Energy Affordability Taskforce.

Budget 2027 did include separate measures relevant to home energy costs:

  • Funding. Over €650 million allocated to SEAI home and community energy upgrades for 2027. A funding allocation is not the same as a change to your own entitlement.
  • Carbon tax on home heating. A cut to carbon tax on home heating oil and gas, which lowers running costs for those fuels but does not change heat pump grant eligibility.
  • Microgeneration income. The income tax disregard for income from selling solar electricity to the grid rises from €400 to €600 a year. Check with Revenue which tax year it applies from.
  • Fuel Allowance. An increase of €5 a week in the Fuel Allowance payment.
Reviewed after Budget Day

This page was reviewed on 7 October 2026, after Budget 2027 and the October 2026 SEAI grant changes. We will review it again after any further SEAI or departmental announcement that changes homeowner grant terms.

FAQ

Frequently asked questions

Can I apply for more than one SEAI grant?

Generally yes. Homeowners can apply for grants covering more than one measure, for example attic insulation and a heat pump, provided each measure meets its own eligibility conditions. Combining measures in one project can also affect which route, individual grants or a One Stop Shop, suits you best. Confirm what can be combined for your own project directly with SEAI.

Do I need grant approval before work starts?

For individual grants and One Stop Shop projects, yes. You need a grant offer from SEAI before work begins. Starting work first is a common reason a grant is refused. The Warmer Homes Scheme is different, since SEAI manages that project for you from the outset.

Do I have to pay the contractor before receiving the grant?

It depends on the route. With an individual grant, you generally pay the full contractor cost yourself and SEAI pays the grant to you afterwards. With a One Stop Shop, the grant is usually deducted from the price upfront, so you only pay the balance. The Warmer Homes Scheme is fully funded, so there is normally nothing to pay.

Can landlords apply for SEAI grants?

Yes. Private and commercial landlords can apply for individual grants and One Stop Shop support on rental properties, alongside separate supports such as the Home Energy Upgrade Loan Scheme. Conditions still apply, so confirm eligibility for the specific property directly with SEAI.

Can first time buyers get higher grants?

A higher fixed grant currently applies for qualifying first time buyers, but only for the attic insulation measure, not across every grant. It generally requires buying an existing home built and occupied before 2011, on or after 1 January 2025, and not having owned a home before. Confirm the current criteria with SEAI before assuming it applies to you.

Can I get a grant if my home received one before?

It depends on the measure and what was previously grant supported. Homeowners who previously received support for one wall insulation measure may now be able to apply for a second wall measure, subject to the current SEAI scheme conditions, though this is not automatic. Other measures have their own conditions, so declare any previous grant support to SEAI at application and confirm your position directly.

Do windows and doors qualify for a grant on their own?

Not on their own. The standalone windows and doors grants currently require the home to already have adequate attic and wall insulation in place, shown through a previous SEAI insulation grant, a BER Advisory Report rating the attic and walls as Good or Very Good, or an assessment by a BER assessor. You do not need to replace every window in the home, but the ones you do replace must meet the required performance standard.

Does every heat pump applicant receive €14,500?

No. Since 6 October 2026, €14,500 is the combined maximum of three separately capped parts: up to €10,500 for the heat pump system, up to €2,000 toward a central heating upgrade such as radiators and pipework, and a €2,000 Boiler Scrappage Grant where an oil, gas or solid fuel system or electric storage heating is removed. That maximum is for a house; the qualifying maximum for an apartment is up to €11,500. Not every project qualifies for every part. Ask your installer and SEAI which parts apply to your own project before assuming the full amount applies.

How long is an SEAI grant offer valid for?

Based on current SEAI guidance, an individual grant offer is generally valid for eight months from the date it issues. If work cannot be completed within that time, contact SEAI, since the current process allows a cover letter explaining the delay to be submitted with your paperwork. Confirm the exact current wording and any conditions directly with SEAI.

Did Budget 2027 change home energy grants?

No. Budget 2027, published on 6 October 2026, did not change SEAI grant amounts or eligibility. The new battery grant, the boiler scrappage grant and wider solar eligibility, which opened the same day, were announced separately by the Department of Climate, Energy and the Environment. Budget 2027 did include separate measures, such as a cut to carbon tax on home heating oil and gas and a higher tax disregard for microgeneration income.

Practical next step

Ready to act on this?

Before requesting quotations, check the relevant SEAI scheme page for your chosen measure, confirm your current eligibility and amount directly with SEAI, and think through the right upgrade sequence for your home. Insulation before a heat pump, for example, often makes more sense than the reverse.
