Housing DPE

State of the diagnosed housing stock and electrification of the main heating energy, class by class and region by region.

Dwellings that have undergone a DPE (sale, rental, new construction), not the entire French housing stock; likely biased toward dwellings being sold or rented.

Source: ADEME - Energy performance certificates for existing housing (since July 2021)

Real data, dataset rebuilt by a repository script from its source. Data read by aggregation from the ADEME database of energy performance certificates for existing housing: 15,705,770 certificates filed from 2021 to 2026, refreshed by the monthly pipeline run. The dataset counts the certified dwellings, not the French housing stock.

Electrification of residential heating

Year-by-year change in the main heating energy declared in DPEs issued that year.

First and last years are incomplete: the current DPE has existed since July 2021, and the current year is still in progress. Read their shares with caution.

Heating energy of diagnostics filed, month by month

Share of electricity and gas in the heating energy of diagnostics filed each month, 2023-09 to 2026-08. The view above describes the diagnosed stock; this one describes the flow feeding it.

A directional indicator, not a volumetric one. An EPC is filed on sale as well as on renovation: this flow is not a flow of works, and it does not say how many boilers were replaced. It says which way what gets diagnosed is leaning. The last two months are excluded: an EPC is transmitted with a delay, and plotting them would show a final drop that is only a collection lag. That two-month delay is a declared assumption, not a measured value: the repository keeps no trace of monthly totals from one run to the next, which makes late reporting impossible to observe, and the last published month remains the least secure point of the series.

Our reading

Among filed diagnostics, the share of electric heating rises from 33.6% to 47% in three years while gas falls from 43.7% to 34.4%: electric overtakes gas for the first time in February 2025, falls back below it six times, and only settles above it from January 2026. It is the earliest signal available on building electrification. It describes what gets diagnosed, not what gets renovated.

Heat pumps supported by energy savings certificates

Energy savings certificate (CEE) files on residential heat pump measures, by year the works were committed, for France as a whole.

795,700

heat pump CEE files committed from 2015 to 2022

242,127

files committed in 2021, the highest year

A CEE file is not an installation in the stock. A heat pump installed without an energy savings certificate is not counted, and the series measures neither the stock nor total sales.

Cells covered by statistical confidentiality are not counted anywhere: a total that contains any is a minimum. The series stops in 2022, the last year of the file by year of commitment; the file by year of completion runs to 2024 but masks most cells from 2023 onwards.
