New EPC Rules from January 2026: Boost for Electric-Heated French Properties

PARIS - Dec. 10, 2025 - PRLog -- The new Energy Performance Certificate (DPE in French) calculation will lower the electricity conversion coefficient from 2.3 to 1.9. This change aligns with European standards and favours properties heated by electricity, potentially improving ratings by one or two classes without any renovations. No property will see its DPE rating worsen under the new method.​

Key Changes to the DPE
The update primarily affects the primary energy factor for electricity, recognising its low-carbon profile from nuclear and renewables over imported gas or oil. Around 850,000 homes, especially small apartments or studios with all-electric heating, stand to gain the most, lifting many from F or G 'energy sieve' categories. Existing DPEs issued after 1 July 2021 remain valid until expiry, but new ones from 2026 will use the updated formula.​

Better accounting for modern equipment like heat pumps and smart thermostats will further enhance scores for upgraded electric systems. This reform encourages electrification, supporting France's green transition without penalising other fuels disproportionately.​

Impact on Property Sales and Rentals
Sellers benefit as upgraded ratings make properties more attractive, dodging future bans on renting G-rated homes (from 2025) and F-rated ones (2028), with C as the target by 2034. Electric-heated homes, common in French resale markets, could fetch higher prices or sell faster post-reform. Buyers gain transparency on true energy costs, though they should verify via fresh DPEs.​

Relevance for Non-Resident Owners
Non-resident Anglophone owners—often British expats with second homes—face heightened scrutiny on DPE validity for sales, as outdated certificates risk deal delays or fines. Many such properties rely on electric heating, so a timely new DPE could elevate marketability, vital when coordinating remotely via agents or notaires. Sellers abroad should commission DPEs early in 2026 to capitalise on gains, avoiding 'passoire énergétique' stigma that deters buyers amid tightening EU rules.​

Plan ahead: instruct your French agent to obtain a post-1 January 2026 DPE, potentially transforming a marginal asset into a compliant, desirable one.
