Key facts

  • Electricity heats 58% of homes with a DPE in Poitiers, against 50% in mainland France.
  • 37% of valid DPEs in Poitiers were generated from the building's DPE, without a rating measured for the flat itself (29% in mainland France).
  • 6.9% of homes with a DPE in Poitiers are rated F or G, against 12% in mainland France — and the gap persists at comparable building age and type (7.1%).
  • 37% of homes with a DPE in Poitiers were built before 1948, against 32% in mainland France.

Energy and climate ratings

Among 23,966 valid DPEs of homes (excluding generated DPEs) in Poitiers, rating C is the most common; 42% reach ratings A to C.

If the homes with a DPE in Poitiers had the same mix of building age and type (house, flat) as mainland France, the F+G share would be 7.1% (+0.1 pt versus the observed figure).

Small homes are the most often poorly rated in Poitiers: 8.6% of assessed homes under 25 m² are rated F or G, against 5.2% for those of 40-69 m².

For 14% of homes with a DPE in Poitiers whose published class is reproduced, the climate rating (greenhouse-gas emissions) sets the DPE class: the final rating is the worse of the two (18% in mainland France).

12% of homes with a DPE in Poitiers whose published class is reproduced would change rating with 5 kWh/m²/year of consumption, or 1 kg CO₂/m²/year of emissions, more or less: they sit on a class boundary (2,983 homes; 12% in mainland France). For them, a small measurement gap or a minor work can move the letter.

G, F and E ratings: the decent-housing timetable

430 homes with a DPE (excluding generated DPEs) in Poitiers are rated G, i.e. 1.8% of homes with a DPE (3.3% in the département, 4.4% in mainland France). Since 1 January 2025, a G-rated home no longer meets the energy performance level of decent housing (Law 89-462, s. 6).

1,233 homes with a DPE (excluding generated DPEs) in Poitiers are rated F, i.e. 5.1% of homes with a DPE (7.2% in the département, 7.2% in mainland France). From 1 January 2028, rating F will no longer meet the energy performance level of decent housing (Law 89-462, s. 6).

3,519 homes with a DPE (excluding generated DPEs) in Poitiers are rated E, i.e. 15% of homes with a DPE (16% in the département, 17% in mainland France). From 1 January 2034, rating E will no longer meet the energy performance level of decent housing (Law 89-462, s. 6).

On 1 January 2027, the electricity primary-energy conversion factor drops from 1.9 to 1.7 (order of 19 August 2026). Among the 1,649 F- or G-rated homes with a DPE (excluding generated DPEs) in Poitiers whose DPE is still valid on that date, whose published class is reproduced and whose scale could be read, 22% could obtain a certificate of a new rating, at least one class better, downloadable from ADEME's DPE-Audit Observatory. The original DPE remains valid until it expires.

Heating and hot water

Electricity comes first: 58% of homes with a DPE in Poitiers rely on it for heating, and 14% have shared heating.

By heating energy, the share of F- or G-rated homes in Poitiers ranges from 2.5% for homes heated by district heating to 56% for those heated with heating oil; it is 4.4% with electricity.

In the 2022 census, INSEE counts 41% of main residences mainly heated by electricity in Poitiers; among homes with a DPE, the share is 58%.

Of the 1,129 homes with a DPE in Poitiers heated by a district network, 95% declare their network's identifier. The main ones: “GRAND POITIERS CHAUFFAGE URBAIN - POITIERS SAINT B” (8601C), 87% of connected homes (0.070 kg CO₂/kWh direct, 0.092 life-cycle). CO₂ contents set by the French order of 30 March 2026, applicable since 25 May 2026: an older DPE may have used other values.

Summer comfort and heat

Over the 1991-2020 normal, Poitiers averages 2 days a year above 35 °C and 1.3 nights above 20 °C; projections for 2050 point to 8.1 and 8.3.

The DPE includes a "summer comfort" section. In Poitiers, 93% of homes with a DPE fill it in; of these, 29% are rated insufficient. This rate depends on who fills in the section, so it is not compared with other cities.

Estimated consumption and cost

The median cost estimated by the DPE in Poitiers is €775 a year for a flat (201 kWh of primary energy per m²) and €1,635 for a house (195 kWh/m²). Per unit of floor area, the median cost of a flat is €21 per m² a year (€21 in the département, €19 in mainland France). This cost is conventional: it assumes standard use and the energy prices in force when each DPE was issued, not a household's actual bill.

Prices and green value

Median price in Poitiers over 2021-2025 sales: €2,193 per m² for a flat (4,539 sales), €2,073 for a house (2,436 sales) — DVF statistics (Etalab).

Estimated advertised rent in Poitiers, charges included, all DPE ratings combined: €12.18 per m² per month for a flat (prediction interval €9.83 to €15.08), €9.91 per m² per month for a house (2025 rent map).

Co-ownerships and collective DPE

The national register of co-ownerships lists 1,251 co-ownerships in Poitiers (Q3 2025 file, all construction periods), with 34,521 residential units in total: 9 have more than 200 units used as homes, offices or shops, 119 between 51 and 200, and 1,123 with 50 units or fewer. Of those with a known period, 38% were built before 1949 and 7.3% after 2010.

The collective DPE covers multi-dwelling residential buildings whose building permit application was filed before 1 January 2013, on a timetable set by the number of units (rule and references in the method). ADEME's database holds 1,443 valid building-level DPEs in Poitiers, single-owner buildings included; one building may have several.

19 co-ownerships in Poitiers are flagged in the register as having received an Anah grant for owners' associations, and 29 are in a priority urban-policy neighbourhood (QPV).

Frequently asked questions — Poitiers

How many energy-inefficient homes are there in Poitiers?

Of the 23,966 homes with a DPE (excluding generated DPEs) since 1 July 2021 whose DPE is valid on 25 August 2026, 1,663 are rated F or G (6.9%), including 430 rated G. At building age and type comparable to mainland France, the share would be 7.1%. These are homes with a DPE, not every home in the city.

Why are some DPEs in Poitiers generated from the building?

37% of valid DPEs in Poitiers were generated from the building's DPE, without a rating measured for the flat itself. The rules allow this for flats in an already-assessed building. These DPEs are counted separately on this page: they report F and G less often in older buildings, and almost never summer comfort.

How are homes in Poitiers heated?

According to their DPEs, homes in Poitiers are mainly heated by electricity (58%), natural gas (35%), district heating (4.7%). In mainland France, electricity heats 50% of homes with a DPE and natural gas 36%.

What do DPEs in Poitiers say about summer comfort?

93% of homes with a DPE in Poitiers fill in the DPE's summer comfort section. Of these, 29% are rated insufficient, 55% average and 16% good. The fill-in rate varies widely: these figures describe DPEs that complete the section, not the whole city.
