Real estate: sales of energy sieves have increased since the beginning of 2025, according to SeLoger

A study by SeLoger highlights an increase in sales of energy-intensive homes, a direct consequence of new regulations and the impact of the DPE on the real estate market.

Sales of so-called "energy-inefficient" homes have increased since the beginning of the year, according to a study by the SeLoger observatory published Thursday. As of July 1, 2021, the share of energy-inefficient homes for sale in France was 10%, compared to 15% as of January 1, 2025, according to the report. Since the beginning of the year, the Climate and Resilience Act has blocked the rental of homes rated G in the energy performance certificate (DPE) . Homeowners have no choice but to undertake often costly renovations.

"The DPE is now a criterion that is almost as structuring as location or surface area." It profoundly redefines "market balances," explains Baptiste Caron, CEO of SeLoger. The other notable aspect of this study is the discount affecting F or G-rated homes. These homes sell for 15% less than D-rated homes. Dwellings rated F and G on the DPE are considered energy sieves.

"This discount on the displayed sale prices is accompanied by increased room for negotiation," the survey explains. Depending on the department, these differences between a D-rated home and an energy-inefficient property can reach 20%, "with peaks of more than 25%." In Paris, as of January 1, 2025, G-rated homes were renting for €1.30 less per square meter than a D-rated home. Since 2018, the government has been recording the energy performance diagnostics (DPE) carried out, which give a rating from A, for the most efficient homes, to G, for the most energy-intensive.
