In 2027, landlords in France who own properties with a G-rated Energy Performance Certificate (Diagnostic de Performance Énergétique or DPE) remain subject to rental restrictions introduced on January 1, 2025, in mainland France. G-rated accommodation no longer meets the energy efficiency requirements for decent housing under the residential tenancy agreements concerned, including new leases and existing agreements when they are renewed or automatically extended. A reform of the French Energy Performance Certificate calculation method, effective January 1, 2027, reduces the primary energy conversion factor for electricity from 1.9 to 1.7, following an earlier adjustment in 2026. This may allow certain electrically heated properties to achieve an improved energy rating without renovation work. Eligible property owners will be able to check their situation and, where applicable, download an official updated energy rating certificate from ADEME, the French Agency for Ecological Transition. The regulatory timetable provides for F-rated properties to become ineligible for the relevant residential rentals from January 1, 2028, followed by E-rated properties from January 1, 2034. F- and G-rated properties are also subject to restrictions on rent increases and annual rent revisions. To improve a G-rated DPE, landlords may consider insulating walls, roofs and floors, upgrading heating systems, improving ventilation or replacing windows. An energy audit can help identify the most appropriate improvements, estimate costs and compare renovation options. Financial assistance may be available subject to eligibility, including MaPrimeRénov', Energy Savings Certificates (CEE), zero-interest eco-loans (éco-PTZ) and certain local grants. For properties in condominium buildings, some improvements require coordination with the property management association and approval from the co-owners' general meeting. To prepare a G-rated property for rental, owners should check their current DPE, assess the impact of the 2027 reform, plan any necessary improvements, explore financial assistance and obtain an energy rating that complies with the applicable regulations. Lodgis supports landlords with rental price estimates, tenant searches and rental property management once their accommodation meets the energy efficiency requirements for decent housing.
Do you own a property with a G-rated Energy Performance Certificate (Diagnostic de Performance Énergétique or DPE) and want to rent it out? Since January 1, 2025, G-rated properties have no longer met the energy efficiency requirements for decent rental accommodation under the relevant French residential tenancy regulations.
In 2027, further changes to the DPE calculation method will provide new opportunities for landlords. In particular, the adjustment to the electricity conversion factor may allow certain properties to improve their energy rating without carrying out renovation work.
However, another important deadline is approaching: January 1, 2028. From this date, F-rated properties will also be affected by rental restrictions.
So, what should you do if your property is rated DPE G in 2027? Which renovations should you prioritize, what financial assistance is available and how can you prepare to rent out your accommodation again? Lodgis explains the key regulations and available solutions.
The French Energy Performance Certificate (Diagnostic de Performance Énergétique or DPE) assesses a property's energy consumption and greenhouse gas emissions.
It assigns an energy rating ranging from A, for the most energy-efficient properties, to G, for the least efficient.
A G-rated property is considered highly energy inefficient, commonly described in France as a passoire thermique (energy-inefficient home).
This rating may result from:
These characteristics can lead to high energy consumption, expensive utility bills for occupants and insufficient thermal comfort.
For landlords, a poor DPE rating also presents regulatory and financial challenges, as it may prevent the property from being rented out.
The calculation method used for French Energy Performance Certificates continues to evolve.
Following an initial adjustment in 2026, the primary energy conversion factor for electricity decreases from 1.9 to 1.7 on January 1, 2027.
This change is expected to benefit certain electrically heated properties, as their energy consumption will be assessed more favorably.
Consequently, some properties may achieve a better energy rating without additional renovation work.
Owners with a DPE issued before the reform will be able to check whether their property is affected and, where applicable, download a free official certificate confirming the updated rating from the ADEME website.
Before undertaking renovation work, it is therefore essential to check whether your property could benefit from the revised calculation method.
In 2027, G-rated properties remain ineligible for new residential leases subject to energy efficiency requirements for decent housing in mainland France.
This restriction, introduced on January 1, 2025, applies in particular to furnished and unfurnished accommodation rented as the tenant's primary residence.
Landlords therefore cannot offer G-rated accommodation under a new residential tenancy agreement covered by these regulations.
The introduction of new energy efficiency requirements does not automatically terminate rental agreements signed before the relevant date.
However, the energy efficiency standards for decent housing apply when a tenancy agreement is renewed or automatically extended.
Tenants may then request that the accommodation be brought into compliance. If a disagreement arises, legal remedies are available under French regulations.
Properties rated F or G remain subject to rent freezes under the applicable rental regulations.
In particular, landlords cannot apply annual rent revisions or certain rent increases when reletting the property or renewing the rental agreement.
These restrictions can directly affect the profitability of a rental property investment.
French regulations establish a progressive tightening of the energy efficiency standards applicable to rental housing.
| Effective date | Energy ratings excluded |
|---|---|
| Since January 1, 2025 | G |
| From January 1, 2028 | F and G |
| From January 1, 2034 | E, F and G |
These deadlines apply to residential leases subject to energy efficiency requirements for decent housing in mainland France, when the agreements are signed, renewed or automatically extended.
2027 represents a crucial stage for owners of energy-inefficient properties.
G-rated accommodation is already subject to rental restrictions, while F-rated properties will have to comply with stricter requirements from January 1, 2028.
Landlords therefore have only a few months left to prepare for the next deadline.
Property owners are advised to review their DPE, assess any necessary renovation work and plan improvements sufficiently far in advance.
Renovating early can help minimize rental vacancy periods and preserve the property's appeal to prospective tenants.
A G-rated property can have several consequences for the management and profitability of a real estate investment.
Accommodation that does not meet the energy efficiency requirements for decent housing cannot be offered under a new residential lease subject to these obligations.
This can result in a period of rental vacancy and a loss of income for the landlord.
Energy performance has become an important consideration for property buyers.
A G-rated property may be less attractive on the real estate market, particularly because of renovation costs and regulatory restrictions.
However, the impact on the selling price depends on the property's location, characteristics and local market conditions.
When a property fails to meet the energy efficiency requirements applicable to the rental agreement, tenants may request that the accommodation be brought into compliance.
In the event of a dispute, a court may order renovation work or decide that the rent should be reduced.
It is therefore essential for landlords to understand their obligations and anticipate the necessary procedures.
Several types of energy renovation work can help improve a property's rating and move it out of class G.
The most appropriate improvements depend on the property's condition, heating system, floor area and main sources of energy loss.
Poor insulation is one of the main causes of excessive energy consumption.
Depending on the property's characteristics, improvements may include:
These measures help reduce heat loss and improve occupants' thermal comfort.
Replacing an outdated heating system can help reduce a property's energy requirements.
Depending on the circumstances, installing a heat pump or another more efficient heating system may be appropriate.
However, the choice of equipment should take into account the property's characteristics and insulation performance.
Appropriate ventilation helps renew indoor air and reduce moisture-related problems.
Installing or improving a mechanical ventilation system (VMC) can therefore form part of a comprehensive energy renovation project.
Replacing old windows with more energy-efficient models can improve insulation and thermal comfort.
However, this is not always the first priority and should be assessed in relation to the property's other sources of heat loss.
Important: not all renovation work will necessarily improve a property's energy rating by a full class. A preliminary assessment is recommended to identify the most effective improvements.
Before undertaking major renovation work, it may be advisable to commission an energy audit.
More detailed than a standard DPE, this assessment identifies the property's main weaknesses and proposes different renovation scenarios.
In particular, it can help:
However, an energy audit is not automatically mandatory when renovating a G-rated property.
It is required in certain property sales, particularly for detached houses and buildings held under single ownership with an E, F or G energy rating.
Different requirements may apply to individual apartments located in condominium buildings.
Energy renovation work can represent a substantial investment. However, several schemes may help finance part of the costs, subject to eligibility requirements.
MaPrimeRénov' provides financial support for certain energy efficiency improvement projects.
Depending on the scheme and the rules in force, it may cover specific improvements or more extensive renovation projects.
Eligibility depends on factors including the property owner's income, the accommodation and the planned work.
Energy Savings Certificate grants (Certificats d'Économies d'Énergie or CEE) can help finance improvements designed to reduce a property's energy consumption.
Certain insulation projects and equipment upgrades may qualify for this assistance.
The zero-interest eco-loan (éco-prêt à taux zéro or éco-PTZ) allows eligible property owners to finance energy renovation work without paying interest.
This financing may be available for certain individual improvements or comprehensive renovation projects.
Some local authorities offer additional grants to encourage improvements in residential energy efficiency.
The amounts available and eligibility requirements vary by location.
Before starting your project, consult France Rénov' to explore the available financial assistance schemes. Eligibility requirements and funding conditions may change from one year to another.
If your property is still rated G, several steps can help improve its energy performance and prepare it for the rental market.
The objective is to bring the accommodation into compliance while controlling renovation costs and preserving its rental value.
Start by reviewing your DPE and checking its validity.
The 2027 calculation reform may change the energy classification of certain electrically heated properties.
Before planning renovation work, check whether your accommodation may qualify for an updated energy rating under the new regulations.
If your property remains G-rated, have the necessary energy efficiency improvements assessed.
Depending on the property's characteristics, targeted improvements may be sufficient. In other cases, more extensive renovation work may be required.
Compare several quotations and research the available funding schemes.
Careful preparation will help you anticipate renovation costs and completion times.
Once the renovations are completed, obtain a new DPE to confirm the property's energy performance.
In 2027, accommodation must achieve at least an F rating to qualify for the residential leases concerned.
However, an F rating will no longer be sufficient from January 1, 2028.
Whenever technically and financially feasible, landlords should therefore aim for at least an E rating, or preferably a higher rating, to anticipate future deadlines.
This strategy can help secure the rental project over a longer period.
For apartment owners in condominium buildings, some energy renovation work may require approval from the co-owners.
This is particularly relevant for work involving the building's facade, roof or certain shared facilities.
It is therefore important to contact the condominium property manager (syndic) to find out about planned building-wide improvements and any decisions already taken.
Some improvements may also be carried out inside individual apartments, subject to any necessary authorizations.
Energy renovation work in a condominium building can provide an opportunity to improve the long-term efficiency of individual apartments and enhance the value of the overall property.
Energy renovation is not simply a matter of regulatory compliance.
It can also represent a strategic investment for landlords.
A property with good energy performance may have an advantage on the real estate market, particularly compared with accommodation requiring substantial renovation work.
Tenants are paying increasing attention to thermal comfort and energy expenses.
A renovated property may therefore be more attractive to applicants looking to manage their housing costs.
Anticipating future regulatory deadlines helps minimize the risk of rental vacancies caused by restrictions on letting energy-inefficient accommodation.
By sustainably improving a property's energy rating, landlords can help preserve their future rental income prospects.

No. Since January 1, 2025, G-rated properties have no longer met the energy efficiency requirements for decent housing applicable to the new residential leases concerned in mainland France. These restrictions remain in force in 2027.
The electricity conversion factor used in the DPE calculation decreases from 1.9 to 1.7 on January 1, 2027. This change may improve the energy rating of certain electrically heated properties without requiring renovation work.
Yes, in certain circumstances. The changes to the DPE calculation method in 2027 may allow some properties to obtain a better energy rating. However, not all properties will automatically benefit from an improvement.
Yes. From January 1, 2028, F-rated accommodation will no longer meet the energy efficiency requirements for decent housing applicable to the residential leases concerned in mainland France. Landlords should therefore prepare for this deadline.
The most suitable improvements depend on the property's layout and characteristics. Better insulation, replacing the heating system and improving ventilation can all contribute to greater energy efficiency.
Yes. Selling a G-rated property remains legally permitted. However, certain sales require a mandatory energy audit, particularly those involving eligible detached houses and buildings held under single ownership.
Several schemes may be available subject to eligibility requirements, including MaPrimeRénov', CEE grants, zero-interest eco-loans and certain local grants. It is advisable to consult France Rénov' to identify the funding options applicable to your project.
In 2027, owners of G-rated properties must continue to comply with the rental restrictions introduced in 2025.
However, the latest change to the DPE calculation method may offer an opportunity for certain owners, particularly those whose properties are heated using electricity.
For other landlords, energy renovation remains essential to restore their property's eligibility for rental under French regulations.
With the restrictions affecting F-rated properties taking effect in 2028, anticipating renovation work and aiming for a lasting improvement in energy performance is becoming a priority for protecting rental profitability and property value.
