08 January 2026
In France, energy performance ratings — known as the DPE (Diagnostic de Performance Énergétique) — play an increasingly central role in real estate transactions. Whether buying, selling, or investing, understanding a property’s French energy rating has become essential, as it directly impacts value, rental eligibility, and long-term strategy. From 1 January 2026, a new reform will modify how the DPE is calculated, reshaping the way energy performance is assessed — particularly for properties heated with electricity. This article explains what is changing with the DPE 2026 reform, why it matters, and how it may affect owners, buyers, and investors in Paris and across France.
