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 per rental property for retrofitting costs over 3 years (€3,333 per year). This is in addition to any SEAI grants received.

Qualifying costs: insulation, heat pump, solar panels, windows, doors, heating controls. Speak to your accountant about claiming this under Section 97A of the Taxes Consolidation Act 1997.
