New 2026 Energy Performance Rules: What International Buyers Need to Know Before Buying in Paris

If you are considering buying an apartment in Paris, a new change to the Energy Performance Certificate (DPE) is worth understanding, as it can directly impact both rental possibilities and long-term value.

From January 1, 2026 the French government is adjusting the way the DPE is calculated by lowering the electricity conversion coefficient. This corrects a long-standing imbalance that penalized electrically heated homes compared with those using gas or fuel oil, many of which rely on imported energy.

This matters in Paris. A large number of Parisian apartments, particularly in historic buildings, are heated with electricity and were previously disadvantaged by the DPE system. The DPE ranks properties from A to G, and those rated F or G - often referred to as “energy sieves” - are subject to strict rules: rental bans, frozen rents, and a noticeable impact on resale value.

According to SeLoger, these apartments sell on average 15% below the price of comparable properties rated D.

With the new calculation method, around 14% of properties previously classified as energy sieves will see their rating improve. The government explains that this reform aligns France with European standards and better reflects the carbon footprint of French electricity, which is largely produced through nuclear power. The measure was confirmed by a decree published in the Journal officiel on August 26, 2025.

🇫🇷 What This Means For You As a Buyer

🥐 More Paris apartments become viable investments

Some properties that were previously excluded from the rental market may now remain rentable, improving flexibility for buyers planning to let their apartment.

🥐 Less pressure on certain electric-heated homes

Apartments with electric heating - very common in Paris - may benefit from a more balanced and realistic DPE rating.

🥐 Still not a free pass on energy performance

A good DPE remains important. Poor insulation, old windows or inefficient systems can still affect comfort, costs and future regulations.

🥐 Renovation strategy matters more than ever

Thoughtful upgrades (insulation, heat pumps, modern water heaters) can significantly improve both livability and value.

🇫🇷 Expert Guidance is Key

Headlines don’t tell the whole story. Each Paris building, apartment layout and co-ownership situation is different, and DPE impact should always be assessed case by case.

For my international clients, buying in Paris is never just about regulations. It’s about finding the right balance between charm, location, lifestyle and long-term value. This DPE reform is a positive development for many Paris apartments, but it should be approached with nuance and professional insight.
