French Energy Diagnostics - Passoires Thermiques (DPE)

Find French homes with a poor energy rating (DPE F or G) from the official ADEME diagnostic database (15M+ records, updated daily). These are the "passoires thermiques": under the loi Climat, renting them out is being progressively banned (class G since 2025, class F from 2028, class E from 2034). Their owners face a legal deadline to renovate or lose the right to rent.

Recherche des passoires thermiques (DPE F et G) par code postal ou département, à partir de la base officielle de l'ADEME. Les diagnostics les plus récents sortent en premier.

Who this is for

• Renovation companies (RGE-certified): a prospect list of addresses that legally need insulation, heating or window work.
• Real estate agents: flag properties whose rental value is at risk, and owners likely to sell.
• Landlords, property managers, energy advisers: audit a street, a building or a whole area.
