To sell your home, classified F on the diagnosis of energy performance (DPE), you must first perform your energy auditthat is to say an analysis evaluating its consumption of gas and electricity and offering work scenarios to improve it. This energy audit, which must be produced by a certified expert, is indeed compulsory since April 1, 2023 for the sale of individual houses classified F and G, in other words the worst Thermal TOCKS. Since January 1, 2025, this obligation has extended to individual houses noted E.

Last December, the realization of the energy audit would have cost you 754.12 euros On average, for an individual house from 90 to 120 m², according to Kiwidiag. But this platform, which offers sellers lists of certified energy audit professionals, warns of a “Significant price increase in the coming months”. In February 2025, Kiwidiag already observed a price increase In some departments, such as the North (+7.5%compared to December 2024), Seine-Maritime (+6.1%) or Finistère (+17.3%).

A more difficult and more expensive certification

Two factors explain this outbreak of energy audit prices. First, the number of audits increases “spectacular”notes Kiwidiag. In December 2024, 21,368 were made in France, a leap of 185% compared to December 2023. In January 2025, the extension of the obligation for the sale of classified houses E caused a new flight, with 30,126 audits made that month, or a quadrupling Compared to January 2024, and an increase of 41 % compared to December 2024. The increase in the number of energy audits also depends on the appeals of owners to public aid with large -scale energy renovations, such as “Maprimerenov ‘ accompanied course ”, which require the realization of such an audit. And “”banks require more and more energy audits to validate requests for financing real estate buyers ”add Kiwidiag.

Then, faced with this growing demand, the number of listeners progressed much more modestly. Between December 2023 and December 2024, It increased by only 7%at 3,961. A decrease of 2% was even observed in February 2025, over a year, illustrating the difficulties linked to their certification. This is indeed “Get more difficult, causing a strong drop in the success rate“, explains Kiwidiag. What is added “there significant increase in training costswhich weighs on independent auditors. The need to go to major cities to pass the examination also involves additional costs of transport, accommodation and loss of income. This is why most listeners who recently passed their certification announce a significant price increase ”, deciphers the platform.
