Real estate diagnostics: where to find a certified diagnoser?

Verified 10 March 2026 - Public Service / Directorate of Legal and Administrative Information (Prime Minister)

The list of certified diagnosers can be consulted on the directory of the website of the Ministry in charge of housing:

Search for a certified real estate diagnoser or check the certificates of its diagnoser

Although the listed diagnosers are certified, it is recommended to verify that their professional indemnity insurance is valid at the time of the intervention. Impartiality (lack of bias) and independence (absence of any link of interest or influence) of the diagnoser vis-à-vis yourself also fall under the essential criteria to be respected.

FYI  

You can call on several professionals to make your real estate diagnostics. Diagnostic prices are not not regulatedThus, the rates may vary from one professional to another for the same diagnosis.
