If your home is heated with electricity, there’s good news on the energy efficiency front. Until now, electrically-heated homes have often been penalised in the DPE (Diagnostic de Performance Énergétique), thanks to a calculation factor that made electricity look less efficient than it really is. Many homes ended up with disappointing energy labels.
What’s changing in 2026?
From 1 January 2026, the electricity conversion factor used in DPE calculations will drop from 2.3 to 1.9. This change could improve the DPE label for many electrically-heated homes - sometimes by a full grade. National estimates suggest around 850,000 homes across France could move out of the “passoire énergétique” (energy-inefficient) category.
Why this matters for homeowners
- Homes currently rated E, F, or G may see their DPE label improve.
- A higher DPE label can make properties more attractive to buyers
- If your home moves out of the E/F/G categories, you may no longer need to provide an energy audit when selling, saving time and money.
Planning ahead
You can already get an idea of your property’s potential new rating using free online simulators. While these are only indicative, they can help you prepare and plan for a reclassification in 2026. If your simulated result looks promising, arranging an official DPE in the new year could make your home easier to sell and more appealing to buyers.
