What is the impact of energy ratings on French house prices?
The French diagnostic de performance énergétique indicates how energy-efficient a property is from A to G, with better ratings sometimes fetching higher sale prices
When a house is put up for sale or rent in France, its owner must hire a professional to carry out a diagnostic de performance énergétique (energy performance certificate or DPE).
This uses a graded rating scheme – from A to G – to indicate how energy-efficient the property is, and to encourage efforts to reduce its consumption.
A recent study published by Notaires de France has examined the effect of this certificate on house and apartment prices.
Overall, it concluded that in some areas of France, properties with a more efficient rating will sell for more than those with a lower rating.
It found that in 2020, 7% of sales concerned properties placed in the most efficient brackets (A and B), while 11% were placed in the least efficient (F and G).
In comparison to 2019, the proportion of A and B-rated properties had increased by 1%, but that of F and G-rated properties had stayed the same.
Houses and apartments are often more energy-efficient on the Atlantic and Mediterranean coasts where the climate is milder, while in the north of France there is a higher proportion of properties with less favourable ratings.

In general, properties with A-B energy ratings are sold for higher prices than those classed in the D bracket, while F-G rated houses and flats are sold for less.
In Nouvelle-Aquitaine, for example, a class A or B house will sell for 12% more than a class D house. However, in other regions the difference is smaller, with Auvergne-Rhône-Alpes recording a variance of just 7%.
In Centre-Val-de-Loire, an energy-efficient apartment will fetch 17% more than a D-rated flat, while in Provence-Alpes-Côte d’Azur there will be no difference whatsoever.

For houses with poor energy ratings, the drop in value ranged between 6% (in Auvergne-Rhône-Alpes) and 20% (in Nouvelle Aquitaine). For apartments, the variation was less extreme, with regions including Centre-Val-de-Loire and Bourgogne-Franche-Comté recording no difference to the value of a D-rated flat.
In general, the price of F or G rated properties dipped slightly lower in comparison to a D-grade property in 2020 than it did in 2019.
For example, the price of a Nouvelle-Aquitaine apartment with a poor rating was 9% lower than average in 2019, but 14% lower in 2020.
It was recently discovered that around 185,000 French properties had been given incorrectly low scores, making them more difficult to sell.
A new calculation supposed to resolve these errors was set to come into force on November 1.
