Understanding Renovation ROI in Ireland
Not all renovations are created equal when it comes to adding value. The Irish property market rewards certain improvements more than others, and understanding the return on investment before you spend helps you make smarter decisions about where to put your money.
Which Renovations Add the Most Value?
Based on SCSI (Society of Chartered Surveyors Ireland) data and market analysis, kitchen renovations and rear extensions consistently deliver the highest ROI in the Irish market. A well-designed kitchen can add 5–10% to a property's value, while a rear extension that adds usable living space can add 8–15%. Attic conversions offer excellent returns for relatively modest cost, particularly in Dublin where space is at a premium.
Energy Upgrades: Value Beyond the Numbers
Energy upgrades deserve special attention. While a heat pump or insulation upgrade might show a lower direct ROI on paper, they deliver value in three ways: improved BER rating (which adds 2–3% per grade improvement), reduced running costs (€1,000–€2,500/year), and access to green mortgage discounts (0.2–0.5% rate reduction). Combined, these can make energy upgrades the best long-term investment.

The BER Factor
A property's BER rating increasingly affects its market value. International research suggests A-rated homes sell for 10–15% more than equivalent D-rated properties. In Ireland, with energy costs rising and buyer awareness growing, BER is becoming a key selling point. If your renovation includes any energy element, get a BER assessment from Homerating.ie before and after to measure the improvement.
For Landlords: Tax-Deductible Renovations
If you're renovating a rental property, certain costs may be tax-deductible. Repairs and maintenance (like replacing a boiler or repainting) are typically deductible in the year incurred. Capital improvements (like extensions) are treated differently. Use our Landlord Tax Calculator to understand the tax implications of your renovation.
