The method of calculating the new DPE will modify the results of approximately 75% of the diagnoses

On this occasion, the online rental agency Flatlooker, analyzed more than 2.000 Energy Performance Diagnostics carried out in recent months as part of housing rentals to understand the impact of these novelties on landlord owners.

In practice, will this measure change a lot of DPE?

By analyzing more than 2.000 DPE, the Flatlooker agency realized that only 25% of them are made according to the now accepted calculation method (3CL). 18% of them are blank, and 57% are done with some other method (Invoices, Th-BCE or other). It is therefore 75% of the DPEs that would be done differently, with a probably different result, from July 1, 2021.

As a reminder, according to the latest Flatlooker study [1] carried out in January 2021, 25% of housing in Paris is thermal strainers (DPE> E).

Will the DPE be poolable between rental and sale? Between a building and an apartment?

The new DPEs will be well shared between rental and sale. The use of a building DPE for housing will not be possible but an apartment DPE can be easily produced from a building DPE. For buildings with collective heating, an extrapolation will be made from a building DPE to qualify that of the housing. We should therefore see an increase in the demand for carrying out DPEs for buildings in order to facilitate the carrying out of diagnostics for housing.

“The use of DPE is simplified with this new diagnosis. Indeed, beyond being usable for the sale as for the rental of housing, it will be possible to carry out the DPE of the housing from a DPE of a building in the case of a building with collective heating for example " .

The DPE now becomes enforceable. What does this mean in practice?

“The old DPE was informative, the new DPE, for its part, will be opposable, ie the owner-lessor or the seller is responsible for the information given to the tenant or to the buyer. If an error is made and the information provided is not correct, it will be possible to take legal action against the owner in order to obtain compensation. ".

How long will the new DPE be valid for? From a former DPE?

The validity period of the new DPE remains 10 years, but the validity date of the old DPE is modified. The oldest DPEs (carried out between 2013 and 2017) thus lapse no later than 31/12/2022. The most recent DPEs (made since 2018 and until 30/06/2021) remain valid until 31/12/2024.

"Owner-lessors or sellers will therefore still be able to use the valid DPEs but will have to make sure to have them carried out again as soon as it is necessary to obtain the new DPE, and fully inform the tenant or purchaser". Thomas Alazet - Real Estate Expert at Flatlooker

How will the new DPE be calculated?

Only the 3CL method is now accepted and relies on the frame. We can no longer rely on invoices to carry out a DPE.

“The fact of not analyzing the bills of the inhabitant will allow to have a more general idea of ​​the consumption of the good and not linked to the precise use of an inhabitant (each one heats his home differently for example). We should therefore have a more reliable result and some homes should see their rating increase a priori. In addition, the new DPE will also lead to a modification of the values ​​for each energy class! ". Thomas Alazet - Real Estate Expert at Flatlooker

Will blank DPEs be accepted?

Blank DPEs are no longer accepted and each DPE must provide an energy performance figure. According to Flatlooker, today around 18% of DPEs in rented accommodation are pristine.

“The information necessary for the diagnostician must be provided, otherwise the DPE can no longer be carried out. It is therefore the disappearance of “virgin” DPE ”. Thomas Alazet - Real Estate Expert at Flatlooker
