⚠️ Article updated on 12 June 2026: the electricity conversion factor dropped from 2.3 to 1.9 on 1 January 2026 (order of 26 August 2025) — if your class-E property is electrically heated, check your new rating via ADEME's free certificate. The "Relance logement" housing bill presented on 23 April 2026 does not change the 2034 deadline for class E.
"My flat is rated E — I have until 2034." Tens of thousands of landlords in France repeat this sentence every week. It is true in its literal form. It is false in what it implies: that you can wait.
The regulatory timetable under the Climate and Resilience Act of 22 August 2021 sets the rental ban for class-E properties at 1 January 2034. But three distinct situations may force you to act well before that date on a legal basis — and three economic realities make waiting costly even if your legal position is comfortable. In total, six concrete reasons why "I have until 2034" is a risky strategy.
This article cuts through exactly what you need to do and when, depending on your situation. It covers: the complete regulatory timetable and its precise conditions; the three cases where you are legally compelled to act before 2034; the three economic reasons why waiting is irrational even if the law permits it; and the quantified cost of inaction.
The Rental Ban Timetable: What the Law Actually Says
The Four Stages of the Regulatory Calendar
The Climate and Resilience Act (Law no. 2021-1104 of 22 August 2021) introduced a progressive ban on letting energy-inefficient properties, codified in article L.173-1-1 of the French Construction and Housing Code (CCH):
- 25 August 2022: rent freeze for all class-F and G properties — no rent increase permitted between tenants or at renewal (decree of 24 August 2022, renewed since);
- 1 January 2025: ban on new lettings and renewals for class-G+ properties (final energy consumption > 450 kWh/m²/year);
- 1 January 2028: ban on all lettings of class-F properties;
- 1 January 2034: ban on all lettings of class-E properties.
Under the 3CL-DPE 2021 method, class E corresponds to a primary energy consumption of 251–330 kWh EP/m²/year and/or CO₂ emissions of 56–80 kg CO₂ eq/m²/year. The less favourable of the two indicators determines the rating.
What the Law Does Not Say: Conditions of Application
Article L.173-1-1 CCH specifies that the ban applies to "residential tenancy agreements" concluded or renewed from the relevant dates. Two important implications: a lease already in force at the ban date is not immediately terminated — the property may continue to be occupied until the lease naturally expires, but cannot be relet afterwards. Additionally, holiday lettings and commercial leases are not covered by this timetable, although legislative changes are under discussion at parliamentary level.
Are You Affected Before 2034?
Before reading the six points below, identify your situation:
| Your Situation | Constraint | Nature |
|---|---|---|
| Your tenant could leave before 2032 | Risk of not being able to relet without works | Legal |
| Your property is in a block without a multi-year works plan (PPT) | Risk of inadequate collective works | Legal |
| Final energy consumption close to 450 kWh/m²/year | Risk of tenant invoking energy decency rules | Legal (specific cases) |
| You plan to sell within the next 5 to 10 years | Growing market discount on sale price | Economic |
| Your property is heated by direct electric heaters | Possible re-rating without major works via heat pump | Economic |
| You have not yet applied for grants | MaPrimeRénov' rates change every year | Economic |
The Three Situations That Create an Obligation Before 2034
Situation 1 — Your Tenant May Leave Before 2032
The rental ban applies to new leases and renewals from 1 January 2034. As long as your current tenant remains in place, you are within the deadline. But if the property becomes vacant before end-2031, you enter a genuine risk zone.
Energy renovation lead times are incompressible. Between the mandatory preliminary energy audit (2 to 4 weeks), selecting contractors and filing MaPrimeRénov' applications (2 to 3 months), and the works themselves (2 to 6 months depending on scope), expect an average of 12 to 18 months end-to-end under current conditions — and likely 18 to 24 months after 2028, when tradespeople will be saturated by urgent class-F compliance works.
⚠️ Warning: A landlord who decides to start renovation works in the summer of 2033 to be compliant by 1 January 2034 is taking a serious risk: empty property unable to be let during the works, zero rental income, service charges and property tax still accruing. The last responsible date to launch a full renovation is, at the latest, early 2032 — and considerably earlier if your property requires substantial works.
Situation 2 — Your Building Has No Multi-Year Works Plan (PPT)
Since 1 January 2023, all buildings of more than 15 lots constructed more than 15 years ago are required to establish a multi-year works plan (plan pluriannuel de travaux, PPT), independently of any individual DPE rating (article 14-2 of the Co-Ownership Act of 10 July 1965, as amended by the ÉLAN Act).
For a landlord whose unit is rated E, this PPT is a poorly-anticipated additional constraint. Collective works voted at the AGM — façade insulation, replacement of communal heating, external redecoration — modify individual DPE ratings, for better or worse depending on their nature and scale. A landlord who has never consulted their building's PPT may discover in 2030 that the planned collective works are insufficient to move their unit from E to D, and that they will need to fund additional private works — without the collective grants negotiated by the building manager.
What to do now: request the PPT from your building manager (communicable to any co-owner on simple request). Check whether insulation or heating works are scheduled before 2034 and their estimated impact on individual DPE ratings. If no PPT exists or the planned works are insufficient, raise the issue at the next AGM.
Situation 3 — Your Tenant May Invoke the Energy Decency Standard (Specific Cases)
The minimum energy decency standard was introduced into French law by decree no. 2023-796 of 18 August 2023. Since 1 January 2025, a property whose final energy consumption exceeds 450 kWh/m²/year may be deemed indecent by the tenant, who is then entitled to demand works or refer the matter to the departmental conciliation committee.
For the vast majority of class-E properties, the 450 kWh/m²/year threshold in final energy is not reached — class E corresponds to 251–330 kWh EP/m²/year in primary energy, two different measures. However, one specific case exists: properties heated by direct electric heaters, for which the electricity conversion factor (1.9 since 1 January 2026, down from 2.3) inflates primary energy consumption without affecting final energy consumption. Certain electrically-heated class-E properties may, depending on their actual consumption, approach or exceed the decency threshold in final energy terms.
What to check on your DPE: look for the final energy consumption figure (in kWh/m²/year), not just the rating. If it exceeds 350 kWh/m²/year, you are in a risk zone worth monitoring, even if you are formally rated E.
The Three Economic Reasons Why Waiting Is Irrational
Reason 1 — The Sale Discount Is Already Underway, and It Is Accelerating
The DPE rating has become a full-blown property valuation parameter. According to notarial analyses published in 2024 and DVF data cross-referenced with the ADEME database, the average discount on a class-E property compared to an equivalent class-C or D property in the same neighbourhood ranges between 3% and 8%, with gaps exceeding 15% in markets where demand is strong and investor-buyers are well informed.
This discount will mechanically widen as 2034 approaches. A class-E property sold in 2025 carries a moderate discount, as the ban is still distant. The same property sold in 2031, three years from the deadline, will be perceived by buyers as a mandatory renovation project — and they will factor that into their offer price.
Reason 2 — The Electricity Coefficient Penalises Properties That a Heat Pump Alone Could Re-Rate
Until 2025, the 3CL-DPE method applied a primary energy conversion factor of 2.3 to electricity (compared to 1.0 for gas and oil). Since 1 January 2026, this factor has been lowered to 1.9 (order of 26 August 2025): 100 kWh of electricity consumed is now recorded as 190 kWh EP instead of 230. Around 850,000 properties left classes F and G through this reform alone, and many electrically-heated class-E properties moved to class D without any works. If this is your case, the free certificate from ADEME's DPE-Audit Observatory makes the new rating official without commissioning a new diagnosis. For properties still rated E, direct electric heating, even with decent insulation, may keep the rating unfavourable even though the actual energy bill remains reasonable.
For these properties — often flats built in the 1980s–2000s under the RT 1974 building regulations with direct electric heating — moving from class E to D or C may require only a single measure: installing an air-to-air or air-to-water heat pump, whose coefficient of performance (COP > 3) mechanically reduces the calculated primary energy consumption by 50–60%. For these specific properties, this is the most cost-effective action in terms of €/class gained, and it can be completed quickly.
Key takeaway: If your property is heated by direct electric heaters and rated E, simulate the impact of replacing the heating system with a heat pump before considering heavy insulation works. The rating improvement may be sufficient with a net investment of €4,000 to €8,000 after grants.
Reason 3 — Grants Are in Place Today; Their Future Level Is Uncertain
MaPrimeRénov' and Energy Saving Certificates (Certificats d'Économie d'Énergie, CEE) are the two main financial levers for funding energy renovation. Several signals suggest that their current conditions are not guaranteed long-term: the MaPrimeRénov' budget was reduced in the 2025 Finance Act compared to the projections made in 2021; eligibility conditions were tightened in 2024 with the introduction of a mandatory prior energy audit for comprehensive renovation projects; and ANAH introduced stricter income thresholds for middle-income households.
Acting in 2025–2026 means benefiting from current rates — which remain substantial. Waiting until 2031–2033 means hoping that public budgets will still be available when all landlords of class-F properties (deadline 2028) and class-E properties (deadline 2034) simultaneously rush towards the same tradespeople and the same grant windows.
The Financial Calculation: What Does Waiting Cost?
Property profile: 65 m² 3-bedroom flat, built in 1982, direct electric heating, rated E (consumption 285 kWh EP/m²/year). Located in Lyon 7th. Estimated value: €320,000 (DVF reference T3 2024 for the area). Current rent: €950/month all-in. Landlord under the actual-income rental tax regime, marginal tax rate 30%.
Scenario A — Action in 2025–2026
| Item | Amount |
|---|---|
| Loft insulation (65 m²) | €4,200 excl. VAT |
| Replace electric heaters with multi-split air-to-air heat pump | €7,800 excl. VAT |
| Total works cost | €12,000 excl. VAT |
| MaPrimeRénov' — 2025 rates, middle-income, zone B1 | − €4,500 |
| CEE (energy savings certificates) estimated | − €900 |
| Net cost to owner | €6,600 |
| Estimated DPE result after works | E → C or D |
| Estimated sale premium (+5% on €320,000) | + €16,000 |
| Net patrimonial benefit | + €9,400 |
Scenario B — Waiting Until 2032
| Item | Amount |
|---|---|
| Same works in 2032 (inflation + overheated trades market) | €16,000 excl. VAT est. |
| Grants — assumed 20% reduction in rates | − €4,300 |
| Net cost to owner | €11,700 |
| Accumulated sale discount (−8% vs. renovated equivalent) | − €25,600 |
| Rental loss during works (2 months vacant) | − €1,900 |
| Net patrimonial cost | − €39,200 |
Total gap between the two scenarios: approximately €48,600 in favour of early action (+€9,400 net benefit in Scenario A vs. −€39,200 net cost in Scenario B). This calculation is indicative and sensitive to inflation and grant rate assumptions, but the order of magnitude is consistent with analyses published by notaries and ADEME on the "green value" of renovated properties.
Financial Levers Available Today
MaPrimeRénov': Two Routes Depending on Scope
MaPrimeRénov' has funded renovation works in two ways since 2024. The single-measure grant funds isolated works (loft insulation, heating replacement, windows) without any rating improvement requirement — fast to access, with no mandatory prior audit for small measures. The comprehensive renovation bonus funds full renovations targeting a gain of at least two energy ratings, with a mandatory prior energy audit — significantly higher amounts, but a longer process.
For a class-E property whose target is to reach class C, the comprehensive renovation bonus is financially the most advantageous route, provided you allow for the additional 3 to 4 months needed to prepare the application.
The Eco-PTZ: Funding Without Upfront Cash
The zero-rate renovation loan (éco-prêt à taux zéro, eco-PTZ) finances up to €50,000 of energy renovation works at zero interest, over a repayment period of up to 20 years, with no income requirements. It can be combined with MaPrimeRénov'. For a landlord who does not wish to use their savings, the eco-PTZ allows the project to start with no immediate cash impact — the monthly repayments being partly covered by rental income after renovation.
The Rental Property Deficit: What Remains in 2026
The temporary doubling of the rental property deficit cap to €21,400 for energy renovation works (Finance Act 2023, article 168) expired on 31 December 2025. The standard cap — €10,700 of rental property deficit deductible against general income per year — remains available to landlords taxed under the actual-income rental regime (article 156 I 3° CGI). For a landlord with a 30% marginal tax rate, a tranche of €10,700 in fully deductible works generates a tax saving of €3,210 — still a meaningful lever, even without the doubled limit.
Common Mistakes Made by Class-E Property Owners
Mistake 1 — Confusing the Ban Date With the Last Date to Start Works
2034 is the date from which you will no longer be legally able to relet your class-E property. It is not the date from which you need to start acting. The realistic lead time for a full renovation breaks down as follows: mandatory prior energy audit (2 to 4 weeks), contractor selection and grant applications (2 to 3 months), works (2 to 6 months depending on scope). Realistic total: 6 to 12 months under normal conditions, 12 to 18 months when the trades market is under pressure. The last responsible date to launch a renovation is, at the latest, early 2032.
Mistake 2 — Assuming Your Class-E Rating Is Stable Over Time
Your current DPE is valid for 10 years. But your property's energy rating can change without you commissioning a new DPE: if the regulations modify the rating thresholds (as happened in 2021 with the move to the 3CL method), or if the electricity conversion coefficient is reduced — which is exactly what happened on 1 January 2026, when it dropped from 2.3 to 1.9 (order of 26 August 2025): many electrically-heated class-E properties moved to class D without any works, the new rating being available through the free certificate from ADEME's DPE-Audit Observatory. A further adjustment remains possible by 2027 under the European EPBD directive. Monitoring regulatory developments is as important as planning works.
Mistake 3 — Focusing on the Letting Constraint and Ignoring the Patrimonial Impact
The 2034 ban is the most visible constraint. But the progressive market discount on class-E properties in real estate transactions is often more costly over time than the legal risk. A landlord who has no intention of selling before 2034 can technically decide to wait. But if they plan to pass the property to their children — see our guide on inheriting an energy-inefficient property — or sell it within the next ten years, they are already experiencing a discount on the value of their asset today — and that discount will grow year by year.
Plan Your Renovation With OneDpe
Do you own a class-E property in France and want to assess your situation concretely?
The OneDpe DPE renovation simulator calculates, for your specific property: the estimated rating improvement for each works package using the 3CL method, the MaPrimeRénov' and CEE grants available based on your profile and location, the impact on rental value after renovation, and the net return on investment over 10 years.

To assess the overall impact of renovation on your rental yield: recalculate profitability after renovation.
Conclusion
2034 is eight years away. Between the incompressible renovation lead times (6 to 18 months depending on scope), the patrimonial discount already underway on class-E properties, the MaPrimeRénov' grants whose future level is uncertain, and the risk of trades market saturation as the major regulatory deadlines approach, every year of inaction has a real and measurable cost.
The right question is not "do I need to act before 2034?" — it is "where do I start to act intelligently?" For most owners of class-E properties with direct electric heating, the first step is simulating the impact of a heating system replacement: it is usually the fastest, least expensive, and most effective action in terms of rating improvement. For properties in co-ownership buildings, it is reading the PPT. For owners who plan to sell within five years, it is calculating the current discount versus the cost of works.
