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.
