What is the purpose of the energy audit? 📃
The energy audit is a new measure aimed at informing buyers of the work to be carried out in their new property in order to
Improve your energy rating.
It brings together a set of proposals for work to be carried out to improve the energy performance of the dwelling concerned. It presents at least two scenarios of work to be carried out in several stages or in a single stage to move the F or G dwellings to class C, (or class B for the E or D classified dwellings before the works). It must lead to at least one class gain, and at least reach class E.
This obligation will be gradually extended:
➤ 1 January 2025 for E-rated properties
➤ 1 January 2034 for D-rated properties
Please note: condominium sales are excluded from the obligation to carry out an energy audit.
When should it be handed over to the buyer? What does it include? 🔍
This audit includes:
- An overall assessment of the property, including thermal and geometric characteristics, as well as information on heating, hot water, ventilation, cooling and lighting equipment.
- An estimate of the building's performance, based on the DPE.
- Proposals for work to improve the energy performance of the building.
For each stage of the work path, the audit should provide the following information:
- An estimate of the expected energy savings.
- Estimating the theoretical impact of the proposed works on the energy bill in the form of a cost savings range;
- Estimate of the cost of the work.
- The list of the main financial aid available at national and local level.
Who can carry out this audit?
There are three types of professionals who can carry out an energy audit:
✔ Certifiedreal estate diagnosticians (certificate issued by a certification body, which must be attached to their audit).
✔ Specialized design offices
✔ Architectural firms registered with the Order and trained
⚠️ Please note: Not all diagnosticians are certified to carry out this audit, even if they have the DPE certification. Further certification is required for single-ownership properties, a diagnostician will not be competent in this case. .
⏳ It should be noted that the energy audit is valid for 5 years.
And for compromises signed before 01/04/2023 (and whose sale is regularized after this date), the audit will not be mandatory. The seller will therefore not have to provide an energy audit at the time of the final sale.
Please note: this only applies to sales agreements. Other types of contracts, such as unilateral promises to sell or buy, are not affected. In the event of signing a unilateral promise, the sale of which has not yet been signed by 1 April, the energy audit must be provided.
