Retrofit grants for landlords
Every grant available to rental property owners in Ireland — including a €10,000 tax deduction most landlords are missing.
The €10,000 tax deduction most landlords do not claim
Since 2023, landlords can claim a tax deduction of up to €10,000 net qualifying expenditure per rental property under section 97B of the Taxes Consolidation Act 1997. This is in addition to any SEAI grants received. The deduction is subject to statutory conditions, timing requirements, caps and clawback provisions.
Qualifying costs include insulation, heat pump, solar panels, windows, doors and heating controls (net of SEAI assistance). Speak to your accountant about eligibility and claim timing.
SEAI grants available to landlords
Many SEAI individual grants are open to landlords as property owners. Insulation, windows and heating controls need a home built and occupied before 2011; heat pumps before 2021; solar and batteries before 2025. Key grants include:
HAP and RAS homes: on 29 September 2026 the Government announced higher attic and cavity wall insulation grants for homes rented under the Housing Assistance Payment (HAP) or the Rental Accommodation Scheme (RAS), and a separate pilot for solar panels and batteries in some RAS tenancies.

Minimum BER requirements for rental properties
Rental property BER standards — current and proposed
- Current minimum standards for rented homes cover structure, heating, ventilation, fire safety and related requirements (Citizens Information)
- BER C and B2 targets for rental properties have been proposed but are not yet enacted into law (as of July 2026)
- A retrofit now protects your rental income long-term and prepares for any future requirements
