France Lowers DPE Electricity Factor, Reclassifying Up to 850,000 F/G Homes From Jan. 1

The recalculation reflects electricity’s lower carbon intensity to revise energy labels.

Le mode de calcul du diagnostic de performance énergétique (DPE) va évoluer au 1er janvier 2026.
En 2026, le calcul du DPE ne pénalisera plus le chauffage électrique, ce qui devrait faire sortir des milliers de logements de leur statut de « passoire thermique ».

Overview

  • Effective 1 January 2026, the DPE’s electricity conversion coefficient drops from 2.3 to 1.9, making results more favorable for electrically heated dwellings.
  • Officials say between 700,000 and 850,000 homes could exit the F/G category without new work, out of an estimated 5.4–5.8 million currently rated F or G. Ademe indicates owners can update their DPE online for free and may see a new label without commissioning a fresh assessment or audit.
  • Real-estate professionals welcome the change as rental bans expand beyond G-rated homes to F in 2028 and E in 2034, while the CNL denounces a giveaway to landlords that harms tenants.
  • The building federation warns the renovation market is weakening after the 2026 suspension of MaPrimeRénov, as MP Daniel Labaronne cites about 80,000 faulty DPEs a year and urges tighter oversight of diagnosticians.
