DPE: The New Regulations In 2025

Reforms, bans, new technical requirements: the Energy Performance Diagnosis (DPE) is undergoing major changes in 2025. If you are an owner, landlord, or investor, these changes will directly impact your real estate projects.

What are the DPE regulations in 2025? Which properties are affected? How can you ensure compliance? BARNES Bordeaux explains what you need to know to anticipate, enhance, and secure your property.

Key Takeaways

• Properties rated G are banned from rental, including as tourist rentals.
• DPE reports carried out between January 2018 and June 2021 have been invalid since January 1, 2025.
• The DPE is now mandatory for tourist rentals in high-demand areas.
• New technical requirements apply from July, September, and October 2025.
• The collective DPE is mandatory for co-ownerships with 50 to 200 units starting in 2025.
• BARNES Bordeaux supports you in anticipating these changes and enhancing your property with tailored guidance.

The DPE: A Quick Reminder

The DPE is a mandatory document for selling or renting a property. It gives a rating from A to G, reflecting both energy consumption and greenhouse gas emissions. The closer the rating is to A, the more efficient, economical, and environmentally friendly the property is.

Since the July 2021 reform, this diagnosis has become legally binding. This means that in case of error, the buyer or tenant can hold the owner liable.

The DPE must be presented as soon as the property listing goes online, and handed over at the signing of the lease or the sale. It has a triple purpose: to inform, to allow comparisons between properties, and to encourage energy renovations.

Energy Performance Diagnosis: What Changes In 2025

The year 2025 marks a turning point for the DPE.

Several measures take effect to strengthen its reliability and accelerate the energy transition:

• Old DPEs Become Obsolete: All reports carried out between January 2018 and June 2021 are no longer valid since January 1, 2025. A new DPE is required if you want to sell or rent.
• Properties Rated G Are Banned From Rental: From 2025, the worst “energy sieves” can no longer be rented. This applies to new leases, as well as tacit renewals if the tenant requests it.
• Tourist Rentals Are Also Affected: From January 2025, a DPE is mandatory for any new tourist rental in high-demand areas. Properties rated G are banned from tourist rental altogether.

These new DPE rules in 2025 aim to remove the most energy-inefficient homes from the market and to encourage owners to renovate. Penalties are provided in cases of non-compliance.

New Technical Obligations

In addition, 2025 introduces several technical measures to strengthen the reliability of the DPE and prevent fraud:

• From July 1, 2025, inspectors must present a QR code proving their certification, to guarantee their legitimacy.
• From September 1, every DPE report must include a unique QR code linking to the property’s official record on the Ademe website, for greater transparency.
• From October 1, the software used must transmit DPE data to Ademe before displaying the results, in order to prevent any influence from the owner.
• The Collective DPE becomes mandatory for co-ownerships with 50 to 200 units, starting in 2025.

These developments aim to make the DPE more controlled, more transparent, and fully aligned with energy transition objectives.

Implications For Owners And Investors

With the new DPE regulations in 2025, owners can no longer afford to remain passive. Renting out a poorly rated property is now risky, or even forbidden.

If your property is rated G, you have two options: renovate to reach at least class F, or withdraw the property from the rental market. Landlords must also anticipate the next steps: F-rated homes will be banned in 2028, followed by E-rated homes in 2034.

That said, these DPE constraints also create new investment opportunities, particularly in properties to be renovated. With the right support, it is possible to enhance these assets through available subsidies (MaPrimeRénov’, CEE…).

At BARNES Bordeaux, our consultants guide you through every step: targeted acquisitions, value enhancement through renovation, or strategic sales. In 2025, the energy rating is no longer a detail: it is a key driver of asset value that we fully integrate into our services.

How To Bring Your Property In Line With DPE Rules In 2025

To comply with the DPE regulations in 2025, it is essential to use a certified inspector. This professional evaluates the property’s energy performance based on precise criteria: insulation, heating system, ventilation, materials, surface area, etc.

As for cost, expect between 140 and 240 euros for the DPE of an apartment, and up to 250 euros or more for a house depending on its size. Note: it is possible to combine several inspections (asbestos, lead, electricity…) to optimize overall costs.

If your property is poorly rated, targeted renovations (insulation, heat pump, double glazing…) can improve the rating. This helps you stay compliant with regulations and increase the property’s value.
