Energy performance certificate in France (DPE): what foreign buyers need to know in 2026

If you are buying property in France, you will encounter a document called the diagnostic de performance énergétique — better known as the DPE — before you even make an offer. It sits inside the mandatory property dossier handed to every buyer, alongside checks for asbestos, lead, termites, and electrical safety.

For most British, American, or Australian buyers, the DPE looks familiar: it resembles the Energy Performance Certificate (EPC) used in the UK and across the EU. But the French version has its own rules, its own rating scale, and — since a major overhaul in July 2021 — its own set of legal consequences that directly affect what you can do with a property after you buy it.

Understanding energy performance in France is no longer optional. Since 2025, the DPE has become a decisive factor in property sales, rental eligibility, and long-term value. This guide explains everything a foreign buyer needs to know, in plain English.

What is the DPE? Understanding energy performance in France

The diagnostic de performance énergétique (DPE) is France’s official energy performance certification for residential and commercial buildings. It has been mandatory for all property sales and rentals since 2006, which means virtually every dwelling listed for sale in France today carries one.

The DPE assigns a property two ratings on an A-to-G scale:

• Energy consumption — measured in kWh of primary energy consumption per square metre per year
• Greenhouse gas emissions — measured in kg of CO₂ equivalent per square metre per year

These two ratings appear as colour-coded letters, identical in format to the energy label system used across the EU. The overall EPC rating displayed on the listing is determined by whichever of the two ratings is worse — so a property with a C for energy consumption but an E for greenhouse gas emissions will be displayed as E overall.

The DPE report covers the key technical elements of the dwelling: insulation (walls, roof, floors), the heating system, domestic hot water production, ventilation, and the type of glazing. Since the July 2021 reform, it also includes estimated annual energy bills and a recommended list of renovation works.

A DPE is valid for ten years from the date of issue — though properties assessed before July 2021 under the old methodology had their validity curtailed and are now expired, meaning sellers of older properties must commission a new assessment.

The July 2021 reform: why the French DPE changed completely

Before July 2021, the French DPE had a significant credibility problem. Assessments were partly based on occupant-declared energy use rather than on the physical characteristics of the building itself. This resulted in inaccuracies that made the ratings unreliable: two identical dwellings could receive different ratings depending on how their occupants used heating. The lack of data on actual energy consumption meant that buyers and tenants could not make meaningful comparisons.

Since 2021, the methodology was completely rebuilt. The new DPE is calculated solely from the physical characteristics of the building in France — its construction, insulation, glazing, heating system, and so on — regardless of who lives in it or how they behave. This change, combined with a recalibration of the rating thresholds, made the new DPE far more stringent than its predecessor.

The practical effect was stark: millions of dwellings that had previously received acceptable ratings were reclassified as F or G under the new scale. French property owners woke up to find that properties they had considered rentable were suddenly classified as energy-intensive or among the least energy efficient in the housing stock.

The A-to-G rating scale explained

The DPE assigns ratings from A (most efficient) to G (least efficient). Here is what each band means in practice for primary energy consumption:

The majority of older French rural properties — stone farmhouses, village houses, period apartments — fall in the D to F range. A G rating is now a serious red flag, not merely cosmetically.

New regulations since 2021: what the DPE means legally

This is where understanding energy performance becomes financially critical for buyers. The French government has tied a phased schedule of restrictions to the DPE rating, with direct consequences for landlords and property owners.

The rental ban timeline

France’s climate and energy legislation introduced a progressive ban on renting out the least energy efficient properties:

• Since 2021: New rental contracts for G-rated dwellings must include a roadmap for energy renovation
• January 2023: Landlords of properties rated G (consuming more than 450 kWh/m²/year) are banned from raising rents on existing tenants
• January 2025: All new rental contracts for G-rated properties are prohibited. Existing contracts can continue but cannot be renewed
• January 2026: F-rated dwellings will be banned from new rental contracts
• January 2028: E-rated dwellings will follow

This means that if you are buying a property in France today with a G rating — whether a holiday home you plan to let or a buy-to-let investment — you are buying a dwelling that is already banned from rental under new regulations. An E-rated property gives you until January 2033 to complete renovation works before the ban applies.

Impact on property sales

The DPE has also become a direct factor in property sales negotiations. Since April 2023, sellers of properties rated F or G are required to provide buyers with a audit énergétique (regulatory energy audit) — a more detailed document than the standard DPE, produced by a qualified assessor, which sets out the full renovation roadmap and estimated costs to bring the property up to at least an E rating.

This audit is separate from and additional to the standard DPE. For buyers, it is an invaluable negotiating tool: it quantifies exactly what improving the energy performance of the property will cost, and it can justify a significant reduction in the asking price.

The energy audit (audit énergétique): what it is and when it applies

The regulatory energy audit is mandatory for any property rated F or G being sold since April 2023. It applies only to single-family houses (maisons individuelles) and multi-unit buildings owned by a single owner — not to apartments in co-ownership (copropriété), which have their own collective energy obligations.

The audit goes considerably further than the standard DPE report. It must include:

• A full assessment of the current state of the dwelling
• At least two renovation scenarios, one of which must bring the property to at least a B rating in a single programme of works
• Estimated costs for each scenario
• Available government grants and subsidies (MaPrimeRénov’, CEE, etc.)

The audit is carried out by an independent, accredited assessor — not the same professional who produces the standard DPE. As a buyer, you receive a copy of the audit before signing the compromis de vente, giving you time to factor renovation costs into your offer.

For foreign buyers in particular, this document is often unfamiliar — many are not aware they are entitled to it, or that it exists at all. If you are buying a house or single-owner building rated F or G, always ask for the audit before making an offer.

What the DPE covers: a technical overview

The DPE report assesses the energy consumption and greenhouse gas emissions of the building by modelling the following elements:

Thermal envelope

• Wall insulation (type, thickness, age)
• Roof and floor insulation
• Type of glazing (single, double, triple)
• Airtightness

Technical systems

• Heating system (boiler type, fuel, age, efficiency rating)
• Domestic hot water production (separate or combined with heating)
• Ventilation system (natural, mechanical, heat-recovery)
• Any renewable energy systems (solar thermal, heat pump, etc.)

Calculated outputs

• Primary energy consumption (kWh/m²/year)
• Greenhouse gas emissions (kgCO₂eq/m²/year)
• Estimated annual energy bills
• Official rating (A to G)

Since 2021, the assessor enters all physical data into a standardised software tool approved by the French government. The output is a standardised DPE report that any buyer or tenant can read and compare across properties.

DPE and EPCs: how France compares to other countries

For buyers coming from the UK, Ireland, or other EU countries, the French DPE will feel familiar — it is part of the same EU energy policy framework, implemented via the Energy Performance of Buildings Directive (EPBD). Energy performance certificates in France serve the same purpose as EPCs elsewhere: informing buyers or tenants about the energy use of a property before they commit.

That said, there are meaningful differences:

Stricter legal consequences. The UK EPC has become a subject of debate precisely because it carries few binding obligations. The French DPE, by contrast, now carries direct rental prohibition for low-rated properties — a legal mandate with real financial consequences.

Two ratings instead of one. The French DPE shows both energy consumption data and greenhouse gas emissions separately, then displays the worse of the two as the headline rating. UK EPCs show a single energy efficiency rating.

Mandatory energy audit for F/G properties. There is no equivalent of the French audit énergétique in most other European systems. It makes France’s system more transparent — and more onerous for sellers of poor-quality stock.

Validity. The French DPE is valid for ten years, the same as most European EPCs.

What to check as a buyer: a practical checklist

When you receive the property dossier (dossier de diagnostic technique, or DDT) from the seller, here is what to look for regarding energy performance:

1. Check the rating letter and date. If the DPE was issued before July 2021, it has expired and the seller must commission a new one. Do not rely on old ratings.

2. Check both sub-ratings. The headline letter reflects the worse of the two scores. A property rated D overall might have a C for energy consumption but a D for greenhouse gas emissions — useful to know if you are considering switching to a lower-emission heating system.

3. For F or G-rated properties: request the audit. If you are buying a house or single-owner building rated F or G, the seller is legally required to provide the audit énergétique. If it is missing from the dossier, ask your notaire to request it before you sign the compromis.

4. Read the renovation recommendations. Even for C, D, or E-rated properties, the DPE includes a list of recommended works to carry out energy renovation. These are not legally binding, but they give you a realistic picture of what improving the energy performance of the dwelling would entail.

5. Factor renovation costs into your offer. For any property rated E, F, or G, treat the estimated renovation costs in the DPE or audit as a negotiating baseline. Energy savings over time are real, but the upfront investment is substantial — typically €15,000 to €60,000+ for a full renovation to reach a C or B rating.

6. Check rental eligibility if you plan to let. If you are buying with the intention of renting — even occasionally — verify that the rating does not fall under the current or upcoming ban. A G-rated property cannot be rented today. An F-rated property cannot be rented from January 2026.

The other diagnostics in the DDT: a quick overview

The DPE is the most consequential document in the dossier de diagnostic technique, but it is not the only one. The full DDT contains a range of mandatory checks, the exact combination depending on the age, location, and type of property:

• Amiante (asbestos) — mandatory for properties with a building permit issued before July 1997. Asbestos in France is found in a wide range of construction materials used up to the late 1990s. The report identifies the presence and condition of asbestos-containing materials.
• Plomb (lead) — mandatory for properties built before January 1, 1949. Relevant primarily to older urban properties with painted surfaces.
• Termites — mandatory in designated risk zones (much of southern and south-western France). Covers the presence of wood-boring insects.
• État des risques et pollutions (ERP) — covers natural risks (flooding, seismic activity, landslides), technological risks, and soil pollution. Mandatory for all properties.
• Électricité and gaz — safety checks on electrical and gas installations older than 15 years.
• Assainissement non collectif — for properties not connected to the public sewerage network.
• Mérule (dry rot) — mandatory in certain northern and western regions.

As a foreign buyer, you are entitled to receive all of these documents before signing the compromis de vente. If any element of the DDT is missing or outdated, your notaire should flag this before you sign.

Key takeaways

• The DPE (diagnostic de performance énergétique) is France’s energy performance certificate, mandatory for all property sales since 2006.
• Since the July 2021 reform, the DPE is calculated from the physical characteristics of the building — not occupant behaviour — making it significantly more rigorous and accurate than before.
• The DPE assigns two ratings (energy consumption and greenhouse gas emissions) on an A-to-G scale. The worse of the two determines the headline letter.
• G-rated properties have been banned from new rental contracts since January 2025. F-rated properties follow in January 2026, and E-rated properties in January 2028.
• Since April 2023, sellers of F or G-rated houses must provide a full audit énergétique detailing renovation costs — a valuable tool for buyer negotiations.
• The DPE is one part of the broader dossier de diagnostic technique (DDT), which also covers asbestos, lead, termites, electrical safety, and natural risks.
• Always check the DPE rating and date before making an offer — and always request the audit if the property is rated F or G.
