SEAI grants: can a new self-build qualify?

If you are building a new house, the SEAI home energy grants for heat pumps and solar panels are not available to you. Include the full installation cost in your build budget.

Both grants are for existing homes and use a cut-off date for when the house was built and occupied. A house you are building now falls after both dates. An installer’s grant deduction cannot make an ineligible house qualify, so ask for a price you can fund without that deduction. Check tax treatment and other supports separately before assuming they will reduce the amount you need.

Check the heat pump age test

Your home must have been built and occupied before 2021 and have a Meter Point Reference Number (MPRN). This number identifies the property’s electricity connection. Having one for your new site does not satisfy the separate age condition.

Do not use a headline retrofit grant amount to reduce your new-build heating budget. The heat pump scheme distinguishes the heat pump itself, required distribution upgrades and scrappage support, with different conditions. Those amounts do not make a new self-build eligible. For an older property, check the live scheme page and obtain a written proposal explaining which components your particular project qualifies for.

For example, a homeowner replacing heating in a house occupied since 2005 has an existing dwelling to assess against the scheme. Someone installing the first heating system in a house being completed in 2026 does not meet the same age test. Neither the installer describing the equipment as grant-compatible nor the equipment appearing on an eligible list changes the dwelling’s eligibility.

Check the solar panel age test

The solar photovoltaic (PV) grant requires an electricity connection number and a house built and occupied before 2025. Homes that previously received solar PV funding at that connection number are also excluded. For an eligible existing home, check the grant amount and conditions when you apply. Do not deduct a retrofit grant from a new-build quote.

Two things follow for a self-builder:

• A house first occupied in 2025 or later is excluded by the age test alone.
• If you moved into a house built earlier, for example one you bought and are now extending, the house may qualify even though you are doing building work.

Check the live SEAI page when you apply.

Why you can’t claim during construction

Get SEAI grant approval before starting the work. A solar grant application cannot be accepted once installation has started.

For a self-build this closes off the workaround that people suggest: build the house, move in, and apply afterwards. The date test is “built and occupied”, and approval has to come before the work, so you cannot retrospectively claim these grants for equipment already installed during construction. Future support for different work would depend on the rules then in force.

Why new builds are left out

The scheme age conditions exclude a house being built now. Separately, new dwellings must comply with Part L energy requirements. The nZEB guide explains the designer’s compliance calculations. These are separate rules: the energy requirements do not establish SEAI’s reason for choosing the grant cut-off dates.

The consequence for budgeting is straightforward. Your designer’s Dwelling Energy Assessment Procedure (DEAP) calculation will show what mix of fabric, heating and renewables you need to pass. That cost belongs in your build budget from the start. See budget and contingency for how to carry it.

What you can still use

Do not budget for SEAI heat pump or solar PV grants on a new build. Other supports have separate conditions:

• Help to Buy. For a first-time buyer building a home, Revenue refunds income tax and Deposit Interest Retention Tax paid in the previous four years, up to a cap that depends on the date of application. It is not a grant. Read the Help to Buy guide for the conditions.
• VAT on a heat pump. The supply and installation of a heat pump heating system qualify for the second reduced VAT rate of 9% from 1 January 2025. The VAT guide covers how that sits beside the 13.5% and 23% rates and the two-thirds rule.
• Vacant Property Refurbishment Grant. This is part of the Croí Cónaithe (Towns) Fund. It concerns existing buildings; do not assume a new build qualifies because the plot was vacant. If your project is a derelict building, read our Vacant Property Refurbishment Grant guide and check the current terms with your local authority’s vacant homes officer.

If you are renovating or extending instead

The age tests apply to the existing house. A house that was built and occupied before 2021 is within the heat pump rule, and one built and occupied before 2025 is within the solar rule. If you are extending an older house, you may qualify for the grants on the existing house’s systems, provided you apply and get approval before the work starts and meet the other scheme conditions.

Keep the order straight: apply, wait for approval, then install. Pay attention to who owns the property, because an application is tied to the MPRN and the homeowner. Tell your home insurer about the proposed work before builders arrive. Ask for confirmation of cover in writing.

Before you budget for a grant

1. Open the live SEAI page for the grant you want. Eligibility is assessed against the scheme terms when you apply.
2. Check your own house against the date test. Both construction and occupation dates matter; a site connection or planning permission date is not a substitute.
3. Ask your designer whether the heat pump and solar panels are already part of the DEAP compliance route. If they are, they are part of the build and not a retrofit.
4. Do not order or install anything on the strength of an expected grant. Approval must come first.
5. Ask the installer to explain in writing which scheme, if any, the quote assumes.

If your construction or occupation dates are unclear, ask SEAI how to establish eligibility before agreeing an installation date. Keep its reply with your application. Use the scheme terms in force when you apply; an earlier quote or a general statement from an installer cannot replace grant approval.

A quote check before you sign

Keep the gross installation cost visible even if a supplier shows a grant deduction. Ask for the equipment, installation, commissioning, tax and optional extras to be itemised. Compare quotes on the same scope rather than comparing a grant-adjusted total from one supplier with an undiscounted total from another.

For a new house, tell the supplier in writing that this is a first installation during construction and give the expected occupation date. Ask them to remove any assumed SEAI deduction from the price you must fund. Keep that response with the quote and your budget. If a supplier says your project qualifies despite the age conditions, ask them for the exact scheme and written confirmation from SEAI before committing money on that basis.

For an extension, distinguish the existing dwelling from the new floor area in your questions. Give the installer the existing home’s construction and occupation history, describe the proposed work and ask which installation the application would cover. Do not treat the extension’s planning status as an answer to the grant question. Put the full price into your cash-flow plan until eligibility and approval are settled. Show the deposit and each payment date separately from any expected grant payment. That lets you see whether you can pay the installer when the bill falls due, even if support is unavailable or arrives later than expected.

If you are working on an existing house instead, see renovating, extending or rebuilding an old house.
