DPE 2026 Reform: What Will Change for Property Buyers and Sellers
From 1st January 2026, the calculation method for the Energy Performance Diagnosis (DPE) is changing. This reform will improve the rating of many properties, particularly those heated by electricity. As a prospective buyer or seller, it is important to understand these changes to better estimate a property's value and make informed decisions.

From 1st January 2026, the calculation method for the Energy Performance Diagnosis (DPE) is changing. This reform will improve the rating of many properties, particularly those heated by electricity. As a prospective buyer or seller, it is important to understand these changes to better estimate a property’s value and make informed decisions.
Good news for electrically heated properties
The government has announced that the coefficient used to calculate electricity consumption in the DPE will be reduced from 2.3 to 1.9. Essentially, this means that electricity will be less penalised in the diagnoses. Result: nearly 850,000 properties currently rated F or G (the so-called “thermal sieves”) could obtain a better rating, without any works.
For example, a property currently rated F could move to E or D simply due to this update of the calculation method.
How this concerns you if you are selling or buying a property
For sellers: if your property is affected, its value could increase from 2026. This may influence the right time to sell.
For buyers: a property currently rated F or G may no longer be considered a “thermal sieve” in 2026. This may change your perception of the property, and its financing (e.g., renovation grants, loan conditions).
Should you wait until 2026 to buy or sell?
It depends on your situation, but it is essential to ask the right questions:
Is the property heated by electricity?
Do you have a recent DPE?
What impact would a change in rating have on your property project?
It may be useful to seek advice from a property professional to assess the consequences of the reform in your specific case.
A useful but not miraculous reform
Please note: this reform does not address insulation problems or excessive consumption. It adjusts a calculation method to better reflect French energy reality, but a poorly insulated property will remain uncomfortable… and expensive to heat.
Conclusion:
The DPE 2026 reform may make a difference for many properties, particularly those heated by electricity. Whether you are a seller or a buyer, take the time to inform yourself. A better understanding of the DPE will enable you to make a calmer and more judicious choice in your property journey.
