If you own a French property and you let it out — or plan to — there is one piece of paper that quietly decides more about your rental income than any tax return: the diagnostic de performance énergétique, or DPE. It’s the energy-efficiency label you’ve probably seen plastered on Seloger listings, colour-coded from A to G, and since 1 January 2025 it has had the power to remove your property from the lettings market entirely.
For British owners — many of whom bought an old stone farmhouse in the Dordogne, a slate-roofed longère in Brittany, or a one-bedroom holiday flat in the Alps (see our step-by-step French property purchase guide for the pre-purchase basics) — the DPE story has moved from a mild administrative nuisance to an income-defining rule. And the ground shifts again on 1 January 2026, with a calculation change that will silently re-score some properties, plus a new obligation for smaller copropriétés, per the Ministère de l’Économie’s December 2025 guidance.
This article walks you through what the DPE actually measures, what changes in 2026, how the rental-ban timeline works for non-residents, what to do if your property is rated F or G, and how to organise a DPE visit when you live 500 miles away.
What the DPE Actually Is
The diagnostic de performance énergétique is a standardised assessment of how much energy your home consumes and how many greenhouse gases it emits. It’s produced by a certified diagnostiqueur after an on-site visit and delivers a single headline letter — from A (extremely efficient) to G (extremely inefficient, colloquially called a passoire thermique, literally “thermal sieve”).
The document is legally required whenever you sell or let a property in metropolitan France, with a handful of exceptions listed in article R126-15 du code de la construction et de l’habitation. The owner pays for it, and it’s added to the dossier de diagnostic technique (DDT) that accompanies any sale or tenancy agreement.
Two points that British owners often miss:
- The DPE is opposable — legally binding. Since 1 July 2021, a tenant, buyer, seller or landlord can sue the diagnostiqueur (and, in some cases, the landlord) if the diagnostic is wrong or negligent. The pre-2021 “informational” DPE is gone.
- It carries a 13-character identification number issued by the Observatoire DPE-Audit run by Ademe (France’s environment agency). Without that number, the DPE is not valid — if a diagnostiqueur hands you a document without one, you don’t have a DPE.
What Changes on 1 January 2026
Two meaningful updates take effect at the turn of the year.
1. A new electricity coefficient — and some labels will improve automatically
The arrêté du 13 août 2025 adjusts the conversion coefficient used to translate electricity consumption into the DPE’s “primary energy” figure — specifically, lowering the factor from 2.3 to 1.9. In plain English: properties heated with electricity have historically been penalised by the calculation, and the new coefficient corrects part of that distortion, bringing France into line with the European default.
Key consequences:
- Any DPE or energy audit produced from 1 January 2026 onwards automatically uses the new coefficient.
- DPEs produced in 2025 or earlier remain valid but can be updated free of charge, with no new site visit, via the Ademe Observatoire website.
- No property will see its label drop because of this change. Some will move up — typically from F to E, E to D, or D to C — depending on how heavily they rely on electric heating.
- As the Ministère de l’Économie estimates, roughly 850,000 homes will exit the F/G “passoire thermique” bracket purely because of the new coefficient — a one-line fiscal rescue for a meaningful slice of the rental stock.
For British owners of rural holiday homes kitted out with electric convecteurs (the cheap wall-mounted radiators you find in a lot of older French houses), this is genuinely good news. A property that was a G or an F on the old coefficient may now sit a rung higher — which, as we’ll see in a moment, can be the difference between legally lettable and not.
2. Small copropriétés (
The loi Climat et Résilience of 22 August 2021 phased in a collective building-level DPE for apartment blocks. The rollout schedule is:
- Since 1 January 2024: monopropriété buildings and copropriétés of more than 200 lots.
- Since 1 January 2025: copropriétés between 50 and 200 lots.
- From 1 January 2026: copropriétés of fewer than 50 lots.
If you own a lot in a small French apartment building, your syndic now has a legal duty to commission a building-level DPE. The cost is split across co-owners according to your tantièmes, so expect a line item on your next appel de fonds.
The Rental-Ban Timeline (and Why It Affects Non-Residents)
This is the part most British landlords underweight.
The loi Climat et Résilience staggered a rental ban on the worst-performing homes. Once a property falls below the threshold for a given date, it cannot legally be offered for a new long-term residential let — furnished or unfurnished — as the property is deemed non décent. The landlord cannot sign a new bail, and existing leases cannot be renewed on the same terms without renovation.
| Date | Label banned from letting | Share of French housing stock (roughly) |
|---|---|---|
| 1 January 2025 | G | ~7% |
| 1 January 2028 | F | ~10% |
| 1 January 2034 | E | ~25% |
As Service-Public.fr sets out, by 2034 roughly one in four French dwellings will be unlettable under the current rules unless upgraded.
Crucially, the ban applies regardless of whether the landlord lives in France. Your legal exposure is the same as a resident landlord’s — and for British owners, that exposure also includes the classic deposit-and-indemnity arguments that still rumble through the Cour de cassation (see our note on the security deposit vs. occupation indemnity ruling). Tenants can go to the commission départementale de conciliation, demand a rent reduction, or sue for forced renovation works — and none of it is paused because you happen to live in Surrey.
A few expat-specific wrinkles to keep in mind:
- Furnished long-term lets (meublés) follow the same timeline. If you’re letting through the loueur en meublé non professionnel regime, our LMNP guide for British investors covers how DPE-driven renovation costs interact with the tax deductions available.
- Short-term tourist rentals (meublés de tourisme) are now subject to their own DPE thresholds under the loi Le Meur of November 2024: A-E required from 21 November 2024 in zones tendues for any newly-offered property, and A-D across mainland France from 2034. Primary residences are exempt. See our separate article on the loi Le Meur and the Airbnb copropriété ban, and — if short-term lets are the whole point of your purchase — the full Airbnb-in-France guide.
- Holiday homes not offered for let are not subject to the ban. Keeping the property purely for personal use side-steps the issue — but of course wipes out any rental income, and in Paris specifically, a vacant flat now faces its own fiscal surcharge (see our piece on the Paris vacant-property tax doubling to 2027).
Reading Your Label: A to G (and What Your Listing Must Show)
The DPE’s front page displays two colour-coded scales:
- The energy-consumption scale — kWh of primary energy per square metre per year.
- The greenhouse-gas scale — kilos of CO₂-equivalent per square metre per year.
The headline letter is the worse of the two. A property that uses modest amounts of energy but runs on oil (fioul) can still come out as F or G because of its carbon footprint, not its consumption. This catches a lot of older rural French homes by surprise.
Small surfaces are a category of their own. Since 1 July 2024 — under the arrêté du 25 mars 2024 — properties under 40 m² have a revised set of thresholds to correct an earlier bias that had put a disproportionate share of studios and one-bed flats in the F/G bracket, an adjustment that affected roughly 140,000 homes. If you own a small flat whose DPE was issued before that date, you can generate a replacement attestation — free, no new visit — via the Ademe Observatoire website.
The label has to appear in every listing
French law requires every sale or rental advertisement — whether posted by an estate agent or by a private owner — to display both the energy letter and the climate letter (A to G). If the property is rated F or G, the ad must carry the mention “logement à consommation énergétique excessive”. The listing also has to show an estimated range for annual energy costs under a standard-use scenario. If you’re listing on Seloger, Leboncoin or Le Figaro from the UK, the portals usually handle this automatically — but check, because an incomplete ad is technically non-compliant. Our remote-management guide for non-residents covers how to run those listings without flying back and forth.
A note on new builds
Buying off-plan (VEFA)? The obligation to produce a DPE doesn’t disappear — it just shifts. In a new build, the maître d’ouvrage (developer) commissions and pays for the DPE, and the promoter hands it to you no later than the day of livraison. It’s valid for 10 years from that date.
What to Do If Your Property Is F or G
If you’ve received — or expect to receive — an F or G label, you have broadly three options.
Option 1: Renovate
The standard interventions that move a French property up the scale are, in order of impact-per-euro for most properties:
- Roof insulation (isolation des combles) — typically the single biggest win for old houses.
- Swap the heat source — out with fioul, in with a heat pump (pompe à chaleur air-eau) or, in a flat, a modern collective system.
- Wall insulation, either external (ITE, more effective but visible) or internal (cheaper, reduces interior surface).
- Double or triple glazing.
- Controlled mechanical ventilation (VMC double flux).
Non-residents can claim MaPrimeRénov’ under the propriétaire bailleur route, but — according to the current Service-Public.fr guidance — the conditions tightened in 2026 and are now worth reading carefully:
- The property must be let as the tenant’s primary residence (résidence principale) for at least 6 years. Break the commitment early and you repay 1/6 of the grant for each remaining year.
- A landlord can fund up to three properties under the scheme.
- Grants are banded by revenu fiscal de référence (blue / yellow / purple / pink). For applications made in 2026, the RFR of 2025 is the reference.
- From 1 January 2026, an in-person, video or phone meeting with a France Rénov’ advisor is mandatory before you can submit a file for any significant renovation — no meeting, no file.
- Also from 2026, wall-insulation-alone and biomass boilers are no longer funded under the “par-geste” route.
If the property is purely a holiday home with no tenant, MaPrimeRénov’ does not apply at all — the scheme is explicitly gated on the property being someone’s primary home.
Option 2: Sell
Selling an F or G property remains legal — there is no sale ban — but the buyer will expect a discount, and you will be required to commission an audit énergétique in addition to the DPE. The audit is a more detailed document produced by a different category of professional, setting out renovation pathways and their costs. It complements the DPE rather than replacing it. Before you commit to selling, read our capital-gains-tax guide for non-residents — the French CGT bill on a long-held property can meaningfully reshape the “renovate vs. sell” arithmetic.
Option 3: Stop letting it
You can keep the property and use it yourself. The ban applies to new lettings — so if you have an existing lease, it continues — but you can’t sign a new one with a banned label. For British owners whose flats were essentially personal bases used occasionally by relatives, this is often the path of least resistance — though if you’re tempted to convert the unit to short-term lets instead, check our coverage of the loi Le Meur (linked above) and the way Parisian copropriétés can now vote to ban Airbnbs altogether. A protected long-term tenant is also less legally fraught than the squatter-and-adverse-possession scenarios walked through in our squatters’-rights explainer, which is worth a skim before you leave a property empty for months.
Arranging a DPE When You Live Abroad
The logistics aren’t as painful as they sound, but the coordination matters.
- Check whether you actually need a new one. A DPE is valid for 10 years. Exceptions: DPEs issued between 1 January 2013 and 31 December 2017 were valid only until 31 December 2022; those issued 1 January 2018–30 June 2021 until 31 December 2024. Anything from 1 July 2021 onwards is valid for the full 10 years.
- Use the Ademe directory to find a certified professional. The official annuaire lists every diagnostiqueur with current certification and mandatory professional insurance. Search by département.
- Get at least two quotes. DPE prices are not regulated and vary from roughly €100 for a small flat to €400+ for a large house. Rural areas can be more expensive simply because the diagnostiqueur has to travel.
- Arrange access. Options, in descending order of convenience: (i) your syndic if a flat; (ii) your letting agent; (iii) a neighbour or family member with a key; (iv) a trip yourself. The diagnostiqueur will need to see every heated room, the boiler, the electrical panel, the windows and the loft.
- Check the 13-character Ademe number on the document you receive. If it’s missing, you don’t have a legally valid DPE.
A practical note on Parisian flats: if your building already has a collective DPE (most copropriétés of 50+ lots do since January 2025), you may be able to rely on an automatically-generated individual DPE derived from the collective one, rather than commissioning a new site visit. Ask your syndic first — it can save you a couple of hundred euros. And if you’re weighing up whether Paris still makes sense against the Riviera or a provincial market, our regional property guide breaks down the trade-offs.
Documents to Prepare Before the Visit
A better-prepared diagnostiqueur produces a better DPE. The French Ministère de la Transition Écologique publishes a helpful checklist (“Préparer mon DPE”) of what to gather. Translated and adapted for British owners:
Administrative
- Acte de propriété (deed of purchase) — gives the year of construction.
- Most recent diagnostic de surface habitable (Carrez or Boutin measurement).
- Your property’s numéro fiscal, accessible via the Gérer mon bien immobilier service in your impots.gouv.fr account.
- Règlement de copropriété if applicable (for tantièmes).
Heating
- Boiler installation and maintenance invoices, including the annual contrat d’entretien.
- The boiler’s original notice (manual).
- Any MaPrimeRénov’ or CEE grant paperwork — the diagnostiqueur cross-references these.
Hot water, ventilation, cooling
- Water-heater installation invoice (confirms install date).
- Ventilation (VMC) installation date and maintenance record.
- Air-conditioning installation invoice and étude thermique if you have one.
Insulation and windows
- Roof-, wall- and floor-insulation invoices, photos during works if you have them, and any professional rapport de sondage.
- Window-replacement invoices and any thermal study.
Renewables
- Solar panel, heat-pump or solar water-heater installation invoices.
Without these, the diagnostiqueur has to fall back on conservative default values — which usually means a worse score than your property deserves.
Cost and Validity
Cost. Prices are unregulated. A reasonable range in 2026 is €100–€250 for a small flat, €200–€400 for a house, and more for larger or remote properties. Get at least two quotes. If you’re paying in sterling and converting, our GBP-to-EUR transfer guide explains how to avoid leaving 2–3% on the table every time you move money to a French contractor.
Validity. Ten years from the date of the diagnostic, with the two historical exceptions for pre-July 2021 DPEs noted above.
Updates. A DPE issued in 2025 or earlier can be updated free via the Ademe Observatoire to reflect the new 2026 electricity coefficient, with no new site visit. Existing older DPEs remain usable as-is until the end of their 10-year validity — the update is optional but often advantageous.
The 2025–2026 Fraud Crackdown
French authorities spent 2025 clamping down on a wave of DPE fraud (diagnostiqueurs issuing labels without visiting, issuing fake labels for renovation-grant claims, or simply operating without certification). Three measures have landed, summarised by Service-Public.fr:
- Volume cap: under the arrêté du 28 juillet 2025, since 1 October 2025 any diagnostiqueur producing more than 1,000 individual-dwelling DPEs over a rolling 12-month period is automatically suspended, barring “justification recevable”. Collective DPEs don’t count towards the cap.
- Tighter certification: the first of two arrêtés du 16 juin 2025 strengthens oversight of the certification bodies themselves by the Comité français d’accréditation (Cofrac) — audits every 10 months rather than 15 — and gives Ademe a dedicated statistical tool for flagging suspicious diagnostiqueurs.
- QR codes — already live: the second arrêté du 16 juin 2025 introduces two QR codes on every DPE. The rollout was staged across autumn 2025: 1 July 2025 — QR code proving the diagnostiqueur’s certification (must be shown on site); 1 September 2025 — QR code linking each DPE to its dedicated Ademe page; 1 October 2025 — the energy and climate labels are only valid once the report has been transmitted to the Ademe Observatoire.
What this means practically: if someone offers to DPE your property for €50 without visiting, or turns up without a professional QR code, walk away. The downside risk — opposable DPE, invalid certification, and a potential lawsuit from your next tenant — is not worth it.
Your 2026 Action Plan
A four-step checklist for British owners of French property, ordered by urgency:
- Find your most recent DPE. Check the date: if it was issued before July 2021, it’s expired or about to expire. If it was issued 2021–2025 on a property with electric heating, request a free update via the Ademe Observatoire to pick up the new coefficient.
- Check your label against the ban timeline. G = cannot sign new lease from January 2025. F = cannot sign new lease from January 2028. E = cannot sign new lease from January 2034.
- If you’re F or G, decide between renovate / sell / stop letting. Don’t wait until 2027 to discover that every diagnostiqueur in your département is booked up and every artisan is quoting 18 months out.
- If your flat is in a small copropriété (<50 lots), ask your syndic when the collective DPE will be commissioned. Your lot’s individual DPE may be generated automatically from it — potentially saving you a new site visit.
- Pencil the administrative knock-ons into your calendar. Any renovation bill you pay in 2026 will feed into your 2027 tax return — our French tax deadlines guide for British owners has the full calendar, and if you’re letting under a strict tenant-guarantee framework, the 2026 Visale updates are worth a read before you re-let a freshly-renovated property.
FAQs
Does a DPE apply to me if I’m a non-resident?
Yes. The DPE is a legal obligation tied to the property, not the landlord’s tax residence. It applies to any sale or letting of a dwelling in metropolitan France.
How long is a DPE valid for?
Ten years, with two historical exceptions: DPEs from 2013–2017 expired on 31 December 2022, and DPEs from 1 January 2018 to 30 June 2021 expired on 31 December 2024. DPEs from 1 July 2021 onward are valid for a full 10 years.
Can I rent out my F-rated property in 2026?
Yes, for now. The ban on F-rated properties only takes effect on 1 January 2028. Existing F-rated leases can continue, and new F-rated leases can be signed during 2026 and 2027 — but renovation lead times are long, so plan accordingly.
How much does a DPE cost?
Prices are unregulated; a reasonable 2026 range is €100–€400 depending on property size, location, and heating type. Get at least two quotes.
Can I update my pre-2026 DPE without paying for a new visit?
If your property is electrically heated, yes — the new conversion coefficient can be applied to your existing DPE free of charge via the Ademe Observatoire website. The updated DPE is equally valid until the original 10-year expiry.
What if my DPE is wrong?
Since 2021, the DPE is opposable. A tenant or buyer who suffers loss because of an incorrect diagnostic can sue the diagnostiqueur, and in some circumstances the landlord as well. Check the 13-character Ademe number and, from 2026, the QR code.
Do holiday homes without tenants need a DPE?
Not automatically. A DPE is triggered by a sale or a letting. If you own a résidence secondaire that you never sell and never let out, no DPE is required — but the moment you decide to sell or offer it on Airbnb, the rules kick in.
What’s the difference between a DPE and an audit énergétique?
The DPE is a standardised label. The audit énergétique is a fuller document setting out renovation pathways, costs and expected gains. An audit is required — in addition to the DPE — whenever you sell a mono-owned F- or G-rated dwelling.
