Energy efficiency is now a measurable financial asset in the Irish property market. A report by Dublin-based valuation company Geowox finds that Irish homebuyers paid a premium of €110,000 for energy-efficient homes in the first quarter of 2026. Homes rated A or B on Ireland’s Building Energy Rating scale achieved a median sales price of €465,000, against €355,000 for homes rated C to G, a gap of 31 per cent, with direct commercial implications for business energy leaders.

The findings confirm energy performance is now a primary value driver in the Irish residential market. Three developments underpin the opportunity: the BER premium is large enough to shift investment decisions; an overhaul of Ireland’s rating system from May 2026 will raise visibility further; and record state investment in retrofit is creating a well-funded pipeline that energy service providers are positioned to capture.

The premium reflects a structural shift in buyer behaviour. The Geowox report, drawing on the residential property price register, shows home sale prices rose 6.9 per cent year on year in the first quarter of 2026, with the median Irish home selling for €385,000. An energy efficiency premium of €110,000 is more than four times that annual price increase, confirming that buyers now price energy performance into decisions as a primary factor.

A regulatory catalyst is imminent. From 24 May 2026, Ireland’s BER scale will be simplified from 15 to 8 categories under the EU Energy Performance of Buildings Directive, with a new A0 classification for zero-emission homes. The change, confirmed by the Department of Housing and SEAI, will make the gap between efficient and inefficient homes more legible to buyers, lenders, and investors across the Irish market.

State investment is matching market demand. Budget 2026 allocated a record €558 million to SEAI residential and community energy upgrades, an €89 million increase on the previous year. For energy service providers, retrofit contractors, and green financiers, this creates a supported and growing market. The SEAI One Stop Shop scheme provides a direct channel to project-managed deep retrofit demand.

Three conclusions stand out for C-suite leaders. First, the €110,000 BER premium provides a concrete return-on-investment argument for customer acquisition. Second, the simplified BER scale arriving on 24 May creates a natural moment to position upgrade services in the market. Third, combining grant support with strong market premiums makes partnering with lenders and developers on green finance a commercially attractive priority.

Energy efficiency has moved from policy aspiration to priced market asset in Ireland. With a €110,000 premium confirmed by transaction data, the retrofit opportunity is no longer theoretical. Business energy leaders who act decisively in 2026 will build strong positions that strengthen with every further tightening of Ireland’s energy performance standards.
