According to the network of real estate agencies Guy Hiccups, 8% of homes put up for sale in France in 2022 were thermal strainers. With a sometimes colossal impact on the selling price.
Since January 1, 2023, the most energy-intensive dwellings, that is to say consuming more than 450 kWh of final energy per m and per year, also called G+, can no longer be rented out, except for energy renovation work. According to a study carried out by the National Energy Renovation Observatory (ONRE), 5.2 million dwellings, out of the 30 million main residences in France, are classified F or G, i.e. 17.3% of the stock, and nearly 150,000 are doing and worse and are therefore already affected by the rental ban.
Often very expensive, have these energy improvements prompted owners to sell their property? For global renovation operations, the amount regularly exceeds 50,000 euros, or even approaches 70,000 euros, confirms Olivier Salleron, president of the French Building Federation. Above all, despite this ban, 31% of owners intend to ignore it and leave their property on the rental market.
The network of real estate agencies Guy Hoquet affirms in a study published by the Sunday newspaper that the market remained stable in 2022 with a total of 8% of homes put up for sale considered a thermal sieve. In Paris, thermal colanders represent 22% of properties for sale against 15% in Dijon, Rouen or Clermont-Ferrand and less than 5% in Montpellier, Marseilles, Toulon and Nice.
A price evolution of 0% minus 30%
Nevertheless, the worst performing homes are clearly losing value. For a property classified F or G with the energy performance diagnosis (DPE), the selling price drops by 6.7% compared to an equivalent dwelling classified C, D or E, according to MeilleursAgents. According to Guy Hocquet’s observations, the discount is real: 10% on average but with 30% peaks in a city like Avignon, against 3% in Paris, and no change in Bordeaux, Rennes, Angers or Orleans where real estate tension remains high.

According to the National Union of Real Estate (Unpi), only 30% of landlords would consider renovating their homes. However, from 2025, class G housing will be prohibited from rental, then it will be 2028 for class F and 2034 for class E.
