Renting Out an All-Electric Home After the 2026 DPE Electricity Coefficient Change
Since 1 January 2026, one quiet number has reshaped the French rental market: the coefficient converting final energy into primary energy for electricity has dropped from 2.3 to 1.9. In plain terms, the primary-energy consumption printed on the DPE of an electrically heated home falls by roughly 17% — with no renovation work at all. For hundreds of thousands of landlords, that means a letter gained on the energy label, and sometimes an exit from the passoire (energy-sieve) status that had banned letting altogether. Enacted by the [arrêté du 13 août 2025](https://www.legifrance.gouv.fr/jorf/id/JORFTEXT000052134589), the change raises very concrete questions: is my home reclassified? do I need a new diagnosis? can I rent it out again? This guide lays out the official figures and the exact steps, so you can re-issue your DPE at the right moment and put your property back on the market in full compliance.
What changed on 1 January 2026
The DPE rates a home in primary energy (kWh/m²/year), not in metered energy. To convert the electricity drawn at the meter (final energy) into primary energy, France applies a conversion coefficient. Until 31 December 2025 that coefficient was 2.3; since 1 January 2026 it is 1.9. - About a 17% drop in the primary-energy figure shown for electrically heated homes (1.9 ÷ 2.3 ≈ 0.83). - No renovation required — the gain is purely methodological and reflects the low-carbon French electricity mix. - Automatic for any DPE or energy audit issued from 1 January 2026. According to the Ministry of the Economy, the aim is to correct an unfair treatment that penalised electricity — a low-carbon energy — against imported gas and heating oil.
Why all-electric homes are the big winners
Because the coefficient applies only to electricity, all-electric homes (electric heating and hot water, convectors, radiators, water tanks) benefit the most. - ≈ 850,000 dwellings leave passoire status (class F or G), per government estimates. - That is nearly one-fifth of the 4.8 million passoires counted on 1 January 2023. - Industry analyses suggest roughly half of electrically heated homes see their label improve, often by a full class. To illustrate: an all-electric home shown at 500 kWh/m²/year of primary energy (class G) falls to about 415 after the 1.9 recalculation (500 × 1.9 ÷ 2.3), tipping it into class F — and back onto the rental market. Figures are indicative; your actual class depends on the full diagnosis.
The arrêté du 13 août 2025: what the text says
The legal basis is the [arrêté du 13 août 2025](https://www.legifrance.gouv.fr/jorf/id/JORFTEXT000052134589) modifiant le facteur de conversion de l'énergie finale en énergie primaire de l'électricité relatif au diagnostic de performance énergétique, published in the Journal officiel n° 0197 of 26 August 2025. Key points of the text: 1. It sets the electricity conversion factor to 1.9 (instead of 2.3) in the DPE calculation methods for homes and non-residential buildings, and for the energy audit. 2. Its Article 5 fixes the entry into force: "Les dispositions du présent arrêté entrent en vigueur le 1er janvier 2026." 3. It aligns France with the EU default value from Directive (EU) 2023/1791 on energy efficiency. The text amends the annexes of the 2021 (residential) and 2006 (non-residential) method decrees.
Getting your recalculated DPE, step by step
You do not need a new on-site diagnosis to benefit from the 1.9 coefficient on a still-valid DPE. Here is what to do depending on your situation.
| Your situation | What to do | Cost |
|---|---|---|
| DPE issued from 1 January 2026 | Nothing: 1.9 is already built in | — |
| DPE issued before 2026, still valid | Download the recalculated attestation from the ADEME DPE-Audit Observatory | Free |
| Expired DPE (over 10 years) or altered home | Commission a new DPE from a certified diagnostician | Paid |
How the coefficient and the letting ban interact
The new coefficient does not change the ban calendar — but it can lift a home out of the blocked classes. The schedule from the loi Climat et Résilience (law no. 2021-1104 of 22 August 2021) still stands:
| DPE class | Letting ban (mainland) | Legal basis |
|---|---|---|
| Worst G (> 450 kWh/m²/yr, final energy) | since 1 January 2023 | loi Climat et Résilience |
| G | since 1 January 2025 | loi Climat et Résilience |
| F | from 1 January 2028 | loi Climat et Résilience |
| E | from 1 January 2034 | loi Climat et Résilience |
Best practice: re-issue the DPE before advertising
Stating the DPE class is mandatory in every rental listing. Advertising with an old G label when your home is now F wrongly presents a "banned" property — and scares off applicants. So the logical order is: 1. Re-issue the recalculated attestation (free, ADEME) or commission a 2026 DPE. 2. Check the new class and the thresholds. 3. Update the listing, the lease and the technical diagnosis file (DDT) with the correct DPE. 4. Archive the dated attestation — in a dispute, that document is what counts. Tracking validity dates, re-issues and mandatory documents quickly becomes a headache once you manage several units. AdminLanding's rental management module centralises DPEs, deadlines and regulatory paperwork to keep every listing compliant.
What the new coefficient does not change
The 1.9 improves the label, not the home's actual comfort or the tenant's bill — the metered electricity consumption is unchanged. Keep in mind: - The DPE stays mandatory to let or sell, and valid for 10 years. - The class must still appear in the listing, the lease and the DDT. - Gas- or oil-heated homes gain nothing: the coefficient applies to electricity only. - An F home is still a passoire until it is renovated; the 2028 deadline is near. Finally, these figures and deadlines may evolve (related bills are under discussion in Parliament). This article is general information, not personalised advice — always check your case on Légifrance, service-public.fr and ADEME before acting.
Conclusion: Cutting the coefficient from 2.3 to 1.9 is no sleight of hand: it realigns the DPE with the low-carbon reality of French electricity, enacted by the arrêté du 13 août 2025. For an all-electric landlord, the reflex is simple — re-issue your attestation free of charge on the ADEME DPE-Audit Observatory, check your new class, then advertise with the correct label. One caveat: these figures and deadlines can change, so always confirm your own situation on the official sources before you commit. A gained letter today is welcome, but the 2028 F deadline still looms.
Frequently asked questions
My all-electric home was class G — can I let it again in 2026?
Possibly. If the 1.9 re-issue moves it to F (or better), it is no longer banned today, because only class G has been off-limits since 2025. Check the new class on ADEME's recalculated attestation before you advertise. Bear in mind, though, that an F home will become unlettable again on 1 January 2028 unless it is renovated.
Do I have to pay for a new diagnosis to get the 1.9 coefficient?
No, not if your DPE is still valid. The recalculated attestation is a free download from the ADEME DPE-Audit Observatory, with no new diagnostician visit required. You only pay for a new DPE if yours is more than 10 years old, has expired, or if the home has been materially altered since the original diagnosis.
Where do I find my DPE number for the re-issue?
It is the 13-character identifier printed at the top right of your DPE report. With that number, go to the ADEME DPE-Audit Observatory to download the updated attestation that applies the 1.9 coefficient. Keep the dated PDF for your listings, the lease and your technical diagnosis file.
Does the recalculated DPE have the same legal value?
Yes. According to service-public.fr, the updated attestation has the same value as the original DPE for both sale and rental. You can use it in the listing, annex it to the lease and add it to the technical diagnosis file. The 10-year validity still runs from the date of the original diagnosis, not the re-issue.
Does the coefficient cancel the 2028 ban on letting F homes?
No. The coefficient does not change the loi Climat et Résilience calendar: class G has been banned since 2025, F will be from 1 January 2028, and E from 2034. The 1.9 can lift a home out of a class, but if it stays or becomes F, the 2028 deadline still applies to it.
How long is my DPE valid?
A DPE is valid for 10 years from the date it was carried out. The free re-issue applying the 1.9 coefficient does not extend that period — it only updates the class. After 10 years, or following major works, you must order a new diagnosis from a certified professional before letting or selling.

Meublé de tourisme: DPE and energy rules in 2026 (loi Le Meur)
If you let a property short-term in France, 2026 is the year energy performance catches up with you. The loi n°2024-1039 du 19 novembre 2024 — the loi Le Meur — pulls meublés de tourisme (furnished tourist rentals) into the same décence énergétique logic that already governs long-term lets. In communes that regulate change of use, a DPE now conditions the right to rent; class F and G properties are being pushed out; and from 1 January 2034 every tourist let that is not the owner's principal residence must reach class D. On top of that, registration goes national in mid-2026 and the taxe de séjour still applies. This guide sets out exactly what the law requires, the dates that matter, which properties are exempt, and how to plan renovations before a deadline — or a fine — forces your hand.
Éco-PTZ for landlords: financing a rental renovation at zero interest in 2026
For a French landlord, a rental rated F or G on the DPE is now a countdown, not just a comfort problem. From 1 January 2025 the most energy-hungry homes can no longer legally be rented, and F-rated flats follow in 2028. Renovating is unavoidable — the real question is how to pay for it without draining your cash. This is where the éco-prêt à taux zéro (éco-PTZ) earns its place: a state-backed, interest-free loan of up to €50,000 over 20 years, open to landlords, with no income condition. This guide walks through the 2026 ceilings, the eligible works and the RGE rule, how the éco-PTZ stacks with MaPrimeRénov and CEE on the same works, the prêt avance rénovation variant, and the tie-in with the déficit foncier and the décence énergétique deadlines.

Mandatory Energy Audit to Sell an F or G Home in France (2026)
Selling a French home rated F or G on its DPE? Since 1 April 2023 you cannot simply hand a buyer the energy label and sign — the law also requires a separate regulatory energy audit (audit énergétique réglementaire). The obligation widened to class E on 1 January 2025, and will reach class D on 1 January 2034. This guide explains, with the exact dates and legal references, what the audit is, how it differs from a DPE, what it must contain (two costed renovation pathways reaching at least class B), who may carry it out, what it costs, and how it dovetails with the ban on renting out thermal-sieve housing. The figures here come from service-public.fr and the Ministère de la Transition écologique; treat them as information, not personalised advice, and confirm your own case at the official source before signing anything.
The Mandatory DPE & Energy Mentions in a French Rental Listing (2026)
What must a French rental listing show about energy? Every annonce must display the DPE energy class (A–G), the GES greenhouse-gas class, the estimated annual energy cost range with its reference year, and — for F or G homes — the mention "logement à consommation énergétique excessive". The DPE must then be handed to the tenant and annexed to the lease. This guide sets out each mandatory mention, since when it applies, and what a wrong or missing one costs.
