A comprehensive study by the Sustainable Energy Authority of Ireland (SEAI) has confirmed that enhancing a home's energy efficiency significantly boosts its market value. Using data from almost 50,000 homes sold during 2023 and 2024, the analysis shows that each step higher on the 15-point Building Energy Rating (BER) scale corresponds to an average price increase of 2.7% nationwide, with rural properties seeing an even greater uplift of 4.7%.
This research utilised actual sale prices rather than asking prices, providing a clear measure of buyers' willingness to pay more for energy-efficient homes. While the capital city, Dublin, displayed a smaller increase—likely due to other priorities such as location and amenities—energy efficiency still contributed meaningful value across all property types and market segments. The findings also suggest that sellers can unlock additional value by upgrading their homes prior to sale.
Beyond financial benefits, the report emphasises the wider advantages of energy-efficient homes, including improved comfort and lower, more predictable energy bills. The SEAI’s home upgrade programmes have supported over 58,600 homes in 2025, investing more than €230 million, with a particular focus on vulnerable households. As energy performance increasingly affects mortgage rates, especially with lenders promoting green mortgages for homes rated B or higher, upgrading homes aligns with both household budgets and Ireland’s climate objectives. Further details and grant information are available on the SEAI website.
