Energy audit: in which cases will it be mandatory on April 1?

Postponed several times to give professionals time to prepare, the obligation for the owners of certain properties to provide an energy audit to their buyer finally comes into force on 1^er april. From now on, it is no longer possible to sell a detached house labeled F or G (the two worst ratings) by an energy performance diagnosis (DPE) without presenting this document.

This is also mandatory for the sale of a collective housing building F or G belonging to a single owner. Single-ownership buildings comprising both shops and housing are also affected. On the other hand, the obligation does not apply to co-ownerships.

The mandatory audit, valid for five years, will be extended gradually: it must target homes classified E from 1^er January 2025, then housing labeled D from 1^er January 2034. This document must be submitted during the first visit of a potential buyer. Sellers must therefore perform the audit before the advertisement is published.

“It’s a new document, but it has similarities with the energy performance diagnosis (EPD) that the public is already familiar with”, reassures Patrice Petit, head of the property administration division for the Orpi agency network. Certified diagnosticians who already establish the DPE can establish this audit. Just like specialized design offices or architects who have undergone training in this field. It is possible to find a qualified professional on the public platform France-renov.gouv.fr.

Work path

The energy audit must provide more detailed information than the DPE, particularly in terms of work recommendations. The document begins with a detailed inventory of the energy and environmental performance of housing, then continues with work proposals, with different scenarios. One must necessarily correspond to a global renovation.

“For those who cannot carry out a global renovation in one go, the audit must present a course of work in different stages”says Seydi Eren, founder of Diagadom, which carries out energy audits.

Other useful information for the potential buyer: the audit also provides an assessment of the cost of the work. Finally, it must indicate the financial aid that can be mobilized for the renovation.

The price of this audit? Diagnosticians and design offices set their prices freely. Figures ranging from 500 euros to 1,500 euros are mentioned. Sellers will have an interest in putting professionals in competition. “It is difficult to market this service beyond 1,000 euros, because the seller must also assume the cost of the other diagnoses to be provided”believes Mr. Eren, however.
