Good news that could boost the value of your property
From 1st January 2026a major reform will modify the Energy Performance Diagnostic (DPE)This is the famous document that now accompanies every sale or letting. And if your home is heated by electricityIf you're looking to improve your environmental performance, you've got a lot to celebrate: your ECD rating could be improve automaticallywithout having to carry out any work!
Why the change?
Until now, the ECD was based on a primary energy coefficient for electricity set at 2,3. This figure was considered too high, and often penalised homes heated with electricity - even if they consumed little.
With the reform, this coefficient increases to 1,9. An update that more accurately reflects the reality of the French energy mix, which is largely made up of low-carbon electricity (nuclear, renewable energies).
Tangible impact for millions of homes
This change will not be trivial. It will have an impact on around 7 million homes across France:
- 91 % of the properties concerned are heated by electricity
- 850,000 homes today rated F or G (the famous heating flats) will change category
- A classified dwelling E could switch to Dan F to E... or even a G to F
- The small areas (studios, T1...) will be the big winners
And in Samoëns, what's the difference for you?
If you own a property heated by electricity in Samoëns, this reform can clearly work in your favour :
✅ No major work required for a better rating
✅ Possibility of rent longer properties currently restricted by regulations (F-rated homes, for example, will continue to be authorised for rental until 2028)
✅ More visibility and appeal on sale or rental adverts
Is it better to wait until 2026 to sell or rent?
It's a legitimate question. Waiting for a better DPE rating to sell at a better price may seem tempting. But there are a few points to bear in mind:
- A DPE is valid for 10 yearseven if it was drawn up before the reform
- L'ADEME will offer a revaluation certificate to update your ECD without redoing everything
- The property market could slow down by the end of 2025 if too many homeowners adopt this wait-and-see strategy.
👉 The right reflex? Anticipate intelligently.
