Initially scheduled for 1 January 2022, the new edition of the Energy Performance Diagnostic (DPE) will only be introduced in September. A slight respite for the property sector. But with this postponement, new changes have taken place, and it's not over yet. Let's take a look at some of the new information that has come out since the beginning of January.

For the sake of the planet, the new ECD has been developed in a much more demanding way than its predecessor, introduced in 2006.

The method of calculation has been thoroughly revised to make it more reliable, closer to reality and more readable.

However, this new ECD calculation formula, which was implemented on 1 July 2021, unfortunately contained an error. As a result, a large number of homes built before 1975 received a very poor DPE score and were therefore wrongly classified as energy flats (class F or G). In fact, in the new DPE, a unique and transposable energy performance evaluation method will be provided for all types of dwellings, regardless of their age.

A problem for people who had requested an ECD to sell their property. A poor rating such as G or F is indeed less attractive to potential buyers. This can both slow down the transaction and result in a lower sale price!

Therefore, a new corrected formula has been introduced.

As of 1 November 2021, the ECDs could therefore be carried out again on the basis of accurate calculations.

- If you have called in a professional to draw up an ECD between 1 July and 15 October 2021, this diagnosis may be incorrect. In total, more than 100,000 DPEs will have to be redone.

- If you are the owner of a property built before 1975, and it has been classified G or F by an ECD between 1 July and 15 October 2021, a new diagnosis will be scheduled automatically and free of charge.

If you are the owner of a property built before 1975 and classified E or D by an ECD during the period indicated, you can also benefit from a new free diagnosis. However, it is up to you to request this from the professional.

It should be noted that from 2025 onwards, all properties classified as F or G in the DPE, qualified as "thermal flats", will be considered as indecent housing and will no longer be able to be offered on the rental market. Unless, however, you first undertake renovation work to improve your property's EPD rating. This will be followed by F housing in 2028 and E housing in 2034.

It is therefore best to anticipate these bans!

So a little advice: renovate before your property is banned from being rented!
