Energy-efficient homes with A and B ratings on BER scale command an almost €100,000 premium
A report by Geowox indicates that energy-efficient homes in Ireland with A or B BER ratings sell for nearly €100,000 more than less-efficient properties. Despite a general decline in housing market transactions, energy-efficient homes have shown greater price resilience.
Why it matters
This highlights the growing financial impact of sustainability and energy efficiency on real estate valuations and consumer purchasing behavior.
THE MOST ENERGY-EFFICIENT HOMES command a premium of close to €100,000 over less-efficient properties.
That’s according to the latest housing market report from Geowox, an Irish property-tech start-up that provides automated property valuation models.
In its housing market report for Quarter 2 of 2026, it found that the median, or mid-point, price for an Irish home reached €393,000, up 6.2% in a year.
However, energy-efficient homes – those rated A-B on the BER system – carried a 27.3% premium, some €97,000, over less-efficient properties rated C–G.
Geowox said this analysis excluded new homes to “isolate the direct impact of energy ratings on existing housing stock”.
The BER (Buildings Energy Rating) system is a measure of a home’s energy usage based on its insulation, size and heating system, among other factors.
