House hunters are paying more for energy-efficient homes and new builds.
That’s according to a new study by Dublin-based data and home valuation company Geowox.
They found that there is a premium of close to €100,000 for a home with a high Building Energy Rating (BER), compared with one which is less efficient to heat.
Their study of the Property Price Register found that the average sale price for all homes in Ireland was €390,000 in the final three months of 2025 – an increase of €20,000 on the same period of 2024. However, homebuyers are having to spend up to a third more for an energy-efficient home.
The study found that the median sale price last year for a home with a BER of between A and B was €450,000 – some €95,000 above the median sales price for homes with a BER rating of C to G. Homes with lower ratings typically sold for €355,000 last year, according to Geowox – a differential of 27%.
This energy-based comparison excludes new homes to gain a more precise understanding of the energy-efficiency premium. However, Geowox found that new homes now cost €440,000 on average, up 5% on the same quarter in 2024. New homes sold for an €85,000 premium over the median for existing homes. This makes new homes nearly 24% more expensive than existing homes.
Prices for apartments were also up by 5% in the year to €336,000.
A total of 16,186 homes were sold in the fourth quarter of last year. This is a fall of 8% on the same period in 2024.
Out of the top 25 urban centres, Dublin city was the most expensive at a median price of €570,000. Longford was the most affordable at €222,000. In Dublin city, prices in Dubin 6 had the highest prices at €850,000 while Dublin 10 had the lowest prices in the capital with a typical price of €328,000.
