Energy performance diagnosis: several measures to secure the device

The energy performance diagnosis (EPD) is mandatory during any sale or rental transaction. It directly influences the value of a property by informing about its energy class, from A to G.

As the reliability of this document is regularly questioned (approximations of calculations, manipulations, fraud, etc.), 2 decrees were published on 16 June 2025, introducing protection measures for consumers and professionals in the sector.

The Order of 28 July 2025, which will enter into force on 1^er October 2025, extends these measures.

Not more than 1 000 DPE

The decree of July 28, 2025 sets a framework for diagnosers with a maximum threshold of diagnoses that can be performed. “Any diagnoser performing more than 1 000 DPE of single-family homes or apartments over a rolling 12-month period will be subject to suspension unless justified,” the Ministry of Ecological Transition said.

Collective residential building EPS and EPS automatically generated by a building diagnosis are not counted in this indicator.

This measure aims to preserve the quality of diagnoses, ensure that each visit is effectively carried out and strengthen users' confidence in the EPD.

Strengthen certification requirements and secure results

The first order of 16 June 2025, amending an order of 20 July 2023, strengthens the requirements on skills of diagnosers and the certification :

• increased monitoring of certification bodies by the French Accreditation Committee (Cofrac) every 10 months (instead of 15 months);
• implementation of a statistical tool integrated into the Agence de l'environnement et de la maîtrise de l'énergie (Ademe) to provide alerts on suspicious behavior and to be able to carry out checks (for example, an abnormally high number of DPEs on the same day or over incompatible distances). Sanctioned diagnosers may be blacklisted for 18 months, or even 24 months in the event of a recurrence.

The second order of the same date, which amends an order of 31 March 2021, establishes security measures on software generating the results of the EPRs and the arrangements for transmission to users:

• a QR code linked to the Ademe will be assigned to each professional and must be presented during any intervention (“the diagnoser presents the QR code on his valid certificate to the sponsor or his representative during the on-site visit of the property”);
• a QR code must allow access to an internet address dedicated to the DPE;
• the result of the EPD will only be accessible after its official registration with Ademe; the display of the energy class and the related carbon class will only be effective once the EPD is transmitted to the Ademe Observatory.

These various measures will be implemented in fall 2025.
