DPE (Energy Performance Certificate) in France: What It Means for Homeowners & Landlords (2026)
The Diagnostic de Performance Énergétique (DPE), introduced by article L126-26 of the Code de la construction et de l'habitation, classifies every French dwelling on a unified A–G scale combining energy consumption (kWh/m²/year) and greenhouse-gas emissions (kgCO₂eq/m²/year) — and since the Loi Climat et Résilience (loi n°2021-1104 du 22 août 2021), the DPE class directly determines whether a property can legally be rented. Class G has been off the rental market since 1 January 2025; F follows on 1 January 2028; E on 1 January 2034. For sellers, a full energy audit (audit énergétique) has been mandatory for class F and G since 1 April 2023, extended to class E on 1 January 2025. The DPE must appear in every sale and rental advertisement, with administrative fines up to €15,000 for missing mentions. This guide explains what the DPE actually measures under the post-2021 3CL-DPE method, walks through the A–G thresholds, lays out the legal obligations and the rental-ban calendar, contrasts the audit énergétique with the DPE itself, and ends with a practical staged-renovation strategy to gain a class. It is written for individual owners and landlords — not for syndics, copropriété assemblies or commercial diagnostiqueurs.
1. What the DPE actually measures
The DPE is a technical document drawn up by a certified independent diagnostiqueur. Since 1 July 2021, it follows a single method called 3CL-DPE 2021 (Calcul de Consommation Conventionnelle des Logements), which replaced the previous "on-invoice" approach. The pre-2021 method calculated energy use from the previous occupant's actual bills — unreliable for second homes, recently-renovated dwellings, or unusual heating habits. Two identical apartments could end up two letters apart simply because one was lived in by a frugal retiree and the other by a young family. The 3CL-DPE 2021 fixes this by computing conventional consumption from the building's physical characteristics — wall composition, glazing, ventilation, heating system, hot-water production, climate zone, altitude — independent of who lives there. Five consumption posts feed the calculation: - Heating (chauffage) - Domestic hot water (eau chaude sanitaire) - Cooling (climatisation) - Lighting (éclairage) - Auxiliaries — pumps, ventilation, controls For each post, the method outputs a primary-energy consumption in kWh/m²/year and a greenhouse-gas emission figure in kgCO₂eq/m²/year. These two figures are projected onto two parallel A–G scales ("étiquette énergie" and "étiquette climat"); the worse of the two letters becomes the DPE class of the dwelling. A gas-heated house with great insulation can therefore lose its A on the energy side because of its CO₂ score on the climate side — by design. Since 1 July 2021, the DPE is also fully opposable under the loi ELAN: a buyer or tenant can sue for damages if the DPE turns out to be materially wrong (recommendations of works keep an indicative value only). That single change is why diagnostiqueurs now charge more carefully and document every input — and why the small-surfaces methodology was specifically refined again on 1 July 2024 to avoid systematically penalising dwellings under 40 m². For most owners, the practical takeaway is that a DPE issued before 1 July 2021 is no longer usable — and a fresh, properly-documented 3CL-DPE 2021 is the only thing that can be cited in a sale, a rental ad, or a MaPrimeRénov' file.
2. The A–G scale and class thresholds
The 3CL-DPE 2021 produces two parallel scales — energy and climate — each from A (most efficient) to G (least efficient). The dwelling's final letter is the worst of the two. Energy scale (kWh/m²/year, primary energy) - Class A: ≤ 70 - Class B: 71–110 - Class C: 111–180 - Class D: 181–250 - Class E: 251–330 - Class F: 331–420 - Class G: > 420 Climate scale (kgCO₂eq/m²/year) - Class A: ≤ 6 - Class B: 7–11 - Class C: 12–30 - Class D: 31–50 - Class E: 51–70 - Class F: 71–100 - Class G: > 100 The dual-criterion rule has real consequences. A 2010-built electric-heated apartment in a well-insulated condo can sit comfortably at C on the energy axis (because electricity in the French primary-energy convention is multiplied by 2.3) but be rated A or B on the climate axis (because French electricity is low-carbon). Conversely, a recently-insulated stone house with a propane boiler may show B on energy but D on climate — and the final DPE class would be D. This design choice — the worse of the two letters — was deliberate: the legislator wanted the DPE to drive both energy savings and decarbonisation. It is also why swapping a fossil boiler for a [heat pump](/en/blog/2025-09-21-heat-pumps-france) is one of the most powerful single moves to gain a class — it cuts energy consumption (the heat pump COP is ~3) and slashes the CO₂ axis at once. For reference: in metropolitan France the 2024 housing stock is roughly distributed as A+B 6%, C 24%, D 32%, E 21%, F 11%, G 6% — meaning about 17% of dwellings sit in F or G and are now (G) or soon (F) blocked from new rental contracts.
3. Legal obligations: when a DPE is required
The DPE is mandatory in three situations: sale, rental, and certain construction projects. On sale. Since 2006, every sale of a residential dwelling must be accompanied by a valid DPE handed to the buyer with the technical due-diligence file (dossier de diagnostic technique, DDT). Since 1 July 2021, the DPE is opposable — a buyer can sue if the certificate proves materially false. The DPE class must be displayed in the sale advertisement alongside the climate class and an estimated annual energy-expenses range in euros (article L126-29 CCH). On rental. Every new lease for residential use — including bail mobilité — must include a valid DPE in the tenant file (article L126-25 CCH). The DPE class and climate class must appear in the rental advertisement. Since 1 January 2022, the estimated energy-expense range must also be shown. Sanctions. Missing or false DPE mentions in an ad expose the seller, landlord, mandataire and agency to administrative fines of up to €3,000 for an individual and €15,000 for a legal entity (article L271-4-1 CCH). For sales, an absent DPE can also justify rescission of the deed in extreme cases. On new construction. A DPE neuf is required at the end of a construction project where the building permit was filed after a date that depends on the project type — for most residential projects from 1 July 2007 onward. Exemptions. A handful of cases escape the obligation: dwellings used less than four months a year, listed monuments under specific conditions, places of worship, dwellings with no fixed heating system, and a few others. Short-term tourism rentals (locations saisonnières) are not technically required to provide a DPE, although a meublé-de-tourisme classification (1 to 5 stars) does require one. The DPE must be provided by the owner at the owner's expense — and renewed when the previous one expires, or when major renovation works invalidate it in practice (a fresh DPE is the only way to demonstrate a class gain after an insulation-and-heating overhaul). For the administrative correspondence around such works — RGE quotes, MaPrimeRénov' files, requests to the syndic for collective work votes — Guide: Démarches en France annotates the relevant forms inline on the official portals.
4. Rental restrictions — the calendar
The decisive rule for landlords sits in article 160 of the loi n°2021-1104 du 22 août 2021 (Climat et Résilience), which redefines what counts as a "décent" dwelling under article 6 of the loi du 6 juillet 1989. A dwelling that fails the energy-decency threshold may not be rented; an existing tenant can sue the landlord to force works or pay damages. The metropolitan calendar: - 1 January 2023 — gel des loyers: rents on class F and G dwellings cannot be increased between two leases or during a lease (already in force). - 1 January 2025 — class G rentals banned. Any new lease, renewal, or tacit reconduction on a class-G dwelling is unlawful. (In force.) - 1 January 2028 — class F banned (same scope). - 1 January 2034 — class E banned. In the DOM-TOM, the calendar is shifted by several years (decree-set, region by region). Crucial point on existing leases. A lease signed and active before 1 January 2025 is not retroactively voided — the ban applies at the moment the contract is renewed or tacitly reconducted. In practice, for a three-year nu unfurnished lease tacitly reconducted, that means the ban kicks in on the next reconduction date. For a one-year furnished lease, it kicks in much faster. What the tenant can do. A tenant in a non-decent dwelling can request the landlord to perform energy works to bring the property up to standard. If the landlord refuses, the tenant may seize the commission départementale de conciliation and, failing agreement, the juge des contentieux de la protection to order works, suspend rent, or terminate the lease at the landlord's expense. Conséquence pratique for owners of passoires énergétiques: the window to renovate without forced rent caps and vacancy is closing quickly. A staged plan over 18–24 months — typically wall insulation, roof insulation, ventilation, and heating swap — usually moves a G to D or E and a F to C or D when the building shell allows it. See our 2026 renovation reform article for the current eco-loan and grant calendar.
5. Audit énergétique vs DPE
Owners selling a passoire énergétique discover a second mandatory document on top of the DPE: the audit énergétique réglementaire. The two documents are not interchangeable. The audit is a deeper, prescriptive study. Where the DPE is a snapshot certificate (4–10 pages), the audit is a 30–60-page technical report including a building survey, a thermal model, at least two work scenarios to bring the dwelling up to class B (or as close as the building allows), itemised cost estimates for each scenario, and the corresponding energy savings, CO₂ reductions, and DPE-class gains. Mandatory scope. Under article 158 of loi 2021-1104, an audit énergétique is required at the time of sale (handed at promesse de vente or acte authentique) for: - Single-family houses (maisons individuelles) and multi-unit buildings owned in monopropriété (one owner of the whole building) classified F or G since 1 April 2023, E added since 1 January 2025, and D scheduled for 1 January 2034. - The obligation does not apply to a single lot inside a copropriété (where the syndic handles collective DPE/audits), nor to the rental flow. Who can perform an audit. Unlike the DPE (any certified diagnostiqueur), an audit énergétique réglementaire must be done by a qualified professional: an architect registered with the Ordre des Architectes who has completed the dedicated training, an RGE-qualified bureau d'études thermiques, or a specifically approved professional (BCEM, OPQIBI 1905, etc.). Cost. Typically €500–€1,500 depending on size and complexity, partially eligible for MaPrimeRénov' funding (up to €500 for low-income households when the audit is carried out before works that benefit from the scheme). Validity. Five years. Practical use. Even when an audit is not legally required, ordering one before a major renovation is the right move: it produces the work-scenario plan that informs the Anah file, the eco-PTZ application, and the staged decision-making between insulation, heating swap, and ventilation. Read in parallel with our 2026 MaPrimeRénov' complete guide.
6. DPE validity and transition rules
DPE validity is calendar-driven, and the transition from the pre-2021 method to the 3CL-DPE 2021 created a window of expiring certificates that has now closed. Standard rule. Any DPE issued from 1 July 2021 onward is valid 10 years. So a DPE drawn up in September 2022 is valid until September 2032; a DPE drawn up today (April 2026) until April 2036. Transition rules (now historical). The legislator gave older DPEs a phased expiry to push owners onto the new method: - DPEs issued between 1 January 2013 and 31 December 2017 were valid until 31 December 2022 — expired. - DPEs issued between 1 January 2018 and 30 June 2021 were valid until 31 December 2024 — expired. As of April 2026, every legally usable DPE in France is therefore a 3CL-DPE 2021 or later. If you are a buyer reading this, any DPE dated before 1 July 2021 in your dossier is invalid and must be redone before signature. If you are a landlord whose DPE pre-dates that cut-off, you cannot rely on it for the rental ad, the tenant file, or the décence claim against the loi 2021-1104 thresholds — order a fresh one. Practical refresh triggers. Even within the 10-year validity, you typically need a new DPE when: - You have completed major works that should improve the class (insulation, heating swap, ventilation overhaul). The class gain is only legally citable once a fresh DPE certifies it. - You file a MaPrimeRénov' Parcours accompagné (mandatory "before" and "after" DPE). - You list a property at a price that depends on the class (a B fetches a higher price than a D in the same neighbourhood). - The diagnostiqueur's certification has lapsed and a buyer's notaire requests reconfirmation — rare but it happens. Small-surfaces methodology. Since 1 July 2024, dwellings with a habitable surface ≤ 40 m² are evaluated under a refined sub-method that corrects systematic over-penalisation for hot-water demand. Existing DPEs on small surfaces issued before that date can be reissued for free by the original diagnostiqueur if the new method gives a better class — worth checking if you own a studio that came out F or G under the original 2021 rules.
7. How to improve a DPE class
Gaining a DPE class is not magic — it is a sequence of building-physics decisions, ranked by impact per euro spent. Here is the staged strategy that works on most French dwellings. Step 1: insulate the envelope. The single highest-impact lever is wall and roof insulation. Roof insulation alone (200–300 mm of mineral wool or biosourced material in a vented attic) can shave 25–30 kWh/m²/year and gain a class on its own. Wall insulation is more expensive — internal (ITI) is cheaper but eats floor area, external (ITE) preserves the inside but costs €150–€220/m² of facade. ITE is also more effective on thermal bridges and protects the structure. Step 2: replace the heating system. Once the envelope is tight, swap the fossil boiler for a heat pump (air-water, geothermal, or hybrid for harder cases). A heat pump with COP 3 cuts primary-energy consumption by ~60% versus a gas boiler and demolishes the climate-axis score because French electricity is low-carbon. This is usually the single best move on the climate scale. Eligible for MaPrimeRénov' (Parcours accompagné or Parcours par geste depending on configuration). Step 3: ventilation and glazing. A double-flow VMC (CMV double-flux) recovers 70–90% of the heat in extracted air and is increasingly required in well-insulated dwellings to avoid mould. Replacing single glazing with double or triple glazing earns moderate gains but matters more for comfort than for the DPE letter. Step 4: domestic hot water. A thermodynamic water heater (CET) or solar thermal addition reduces the ECS post — typically 8–15 kWh/m²/year saved depending on household. Step 5: small auxiliary fixes. LED lighting (already on most homes), smart heating controls, programmable thermostats — minor on the DPE but cheap to add. Realistic class trajectories. - G → E or D: full envelope + heating swap, 18–24 months, €30,000–€60,000 gross before subsidies, often €15,000–€35,000 net after MaPrimeRénov' + CEE for an eligible household. - F → C or D: similar scope but less envelope work, often €20,000–€45,000 gross. - E → C: heating swap + targeted insulation, often €12,000–€25,000 gross. Critical detail. A class gain is only legally citable once a fresh DPE certifies it — keep that in mind for the rental-ban calendar. Plan the post-works DPE into the renovation timeline.

8. Where AdminLanding fits
Once the DPE class is on your radar — whether you are buying, selling, renting, or planning a renovation — the next steps are administrative: ordering a fresh DPE, filing MaPrimeRénov', talking to Anah, requesting an Eco-PTZ from your bank, getting RGE quotes, and following up with the syndic for any collective vote on common-area works. This is where AdminLanding's two products help. [Guide: Démarches en France](https://play.google.com/store/apps/details?id=com.adminlanding.admi&hl=en&utm_source=greendailyfix&utm_medium=blog&utm_campaign=guide-app&utm_content=2026-04-26-dpe-diagnostic-performance-energetique-2026) or [App Store](https://apps.apple.com/us/app/guide-démarches-en-france/id6773071351) is an AI assistant that overlays maprimerenov.gouv.fr, monprojet.anah.fr, france-renov.gouv.fr, service-public.fr, impots.gouv.fr and 23 other official portals with field-by-field annotations: which document to upload, which RGE certification number to copy from your artisan's quote, which DPE attestation goes where, what to do when the form rejects your file. It is bilingual EN/FR and runs as a Chrome/Edge extension on desktop or a Play Store app on Android. Pricing: included with AdminLanding Pro at €14.99/month. [AdminLanding's MaPrimeRénov' filing toolkit](https://www.adminlanding.com/maprimerenov-en?utm_source=greendailyfix&utm_medium=blog&utm_campaign=maprimerenov&utm_content=2026-04-26-dpe-diagnostic-performance-energetique-2026) centralises the document checklists, ready-to-sign letter templates (RGE quote requests, Anah follow-ups, syndic mise-en-demeure for collective works) and a workflow for the Parcours accompagné — the route that produces the largest grants and that legally requires Mon Accompagnateur Rénov' supervision. For adjacent reading on the policy backdrop: - MaPrimeRénov' 2026 complete guide — current grant amounts, household income brackets, eligible works. - 2026 renovation reform — heat pumps, eco-loans, DPE — what changed in the LFSS 2026 and the renovation framework. - France heat-pump market 2026 — pricing, supply, installer availability. - Heat pumps Europe 2026 — the EU-wide context. None of this replaces a certified diagnostiqueur or a Mon Accompagnateur Rénov' — but it removes most of the friction between owning a passoire and starting a credible renovation file.
Conclusion: The DPE is no longer a paper formality — it is the single hinge between a property's value, its rentability, and its renovation roadmap. Class G is already off the rental market; F follows in less than two years; the audit énergétique requirement at sale now reaches class E; and the only DPEs that count today are 3CL-DPE 2021 certificates issued from July 2021 onward. For owners and landlords, the practical playbook is: order a fresh DPE if yours pre-dates 1 July 2021, plan a staged renovation if you sit in F or G, sequence insulation before the heating swap, and budget for a post-works DPE to legally certify the class gain. The administrative side — MaPrimeRénov', Anah, eco-PTZ, RGE quotes — is where most files lose months. Guide: Démarches en France or App Store and the AdminLanding renovation toolkit take that friction out — annotating the official forms, drafting the right letters, and walking your file through to grant approval.
Frequently asked questions
What does the DPE measure exactly?
The DPE measures conventional primary-energy consumption (kWh/m²/year) and greenhouse-gas emissions (kgCO₂eq/m²/year) of a dwelling, computed under the 3CL-DPE 2021 method from physical building characteristics — wall composition, glazing, heating system, ventilation, hot water, climate zone — independent of the current occupant's habits. Five posts are taken into account: heating, domestic hot water, cooling, lighting and auxiliaries. The dwelling is assigned an energy letter (A–G) and a climate letter (A–G); the worse of the two becomes the DPE class.
When are class G/F/E rentals banned in France?
Under article 160 of the loi n°2021-1104 du 22 août 2021 (Climat et Résilience), class G dwellings have been banned from new rental contracts in metropolitan France since 1 January 2025. Class F follows on 1 January 2028, and class E on 1 January 2034. Existing leases are not retroactively voided, but the ban applies at renewal or tacit reconduction. DOM-TOM follow a slightly delayed calendar set by decree.
How long is a DPE valid?
Any DPE issued from 1 July 2021 onward is valid 10 years under the 3CL-DPE 2021 method. Older DPEs were given transitional expiries: those issued between 1 January 2013 and 31 December 2017 expired on 31 December 2022, and those issued between 1 January 2018 and 30 June 2021 expired on 31 December 2024. As of April 2026, every legally usable DPE in France is therefore a post-July-2021 certificate. A new DPE is also needed after major renovation works to legally certify any class gain.
Do I need an audit énergétique to sell my home?
Yes, if you are selling a single-family house or a fully-owned multi-unit building classified F, G or E on the DPE. The audit énergétique réglementaire has been mandatory at sale for class F and G since 1 April 2023 under article 158 of loi 2021-1104, extended to class E since 1 January 2025, and will extend to class D from 1 January 2034. The audit is handed at promesse de vente or signature of the acte authentique. It does not apply to a single lot inside a copropriété or to rentals. Cost typically €500–€1,500.
Can I rent a class G property to a current tenant?
If the lease was signed and active before 1 January 2025, it remains valid for now — the ban does not retroactively void in-force leases. But the ban applies at renewal or tacit reconduction. For a three-year unfurnished lease tacitly reconducted, the next reconduction date is your deadline; for a one-year furnished lease, it comes much faster. The tenant can also request energy works during the lease and, if refused, seize the commission départementale de conciliation or the juge des contentieux de la protection.
How much does a DPE cost?
DPE pricing is not regulated in France — each certified diagnostiqueur sets their fee. Typical observed prices range from €100 to €250 depending on size and complexity. Indicative bands: a studio or small flat €80–€100, a 4-room flat €120–€170, a 100 m² house around €200, larger houses €250 and above. Unlike the audit énergétique, the DPE is not eligible for any direct public subsidy. Always ask for at least two quotes and verify the diagnostiqueur's certification on annuaire-diagnostiqueurs.developpement-durable.gouv.fr.
How can I improve my DPE class?
Work in stages, ranked by impact per euro: insulate the roof first (often a one-class gain on its own), then walls (ITE preferable to ITI when feasible), then swap the fossil boiler for a heat pump (the single biggest move on the climate axis), then upgrade ventilation (double-flow VMC) and hot-water production (thermodynamic). A G→D trajectory typically requires €30,000–€60,000 gross over 18–24 months, often €15,000–€35,000 net after MaPrimeRénov' and CEE. The class gain is only legally citable once a fresh DPE certifies it — plan the post-works DPE into the timeline.

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.
Wrong DPE in 2026: A Landlord's Recourse When the Diagnostic Is Binding
Is the DPE legally binding, and what can you do if yours is wrong? Since 1 July 2021 the DPE is opposable — binding like other property diagnostics — so a tenant can hold you liable for errors. But that street runs both ways: if your home is wrongly classed F or G and blocked from letting, you can commission a new DPE from another certified diagnostician, claim against the original one, or pull a free re-edited DPE.

No. Since 24 August 2022, the rent of a "passoire thermique" (DPE class F or G) in mainland France is frozen: no IRL indexation, no increase at renewal, none between tenants — until renovation lifts it to class E or better, proven by a new DPE.
Energy-Poor Homes 2026: Which Classes Are Banned From Renting, and When
If you own a French rental rated F or G on its DPE, the clock is no longer ticking — for class G it has already struck. The loi Climat et Résilience phases energy-poor dwellings (passoires thermiques) out of the rental market on a fixed calendar, and a home that is no longer 'decent' cannot legally be rented. Here is exactly which classes are banned, on which dates, what it means for your existing tenancies, and the four moves a landlord can make right now.
