Key facts
- Natural gas heats 53% of homes with a DPE in Reims, against 36% in mainland France.
- 55% of valid DPEs in Reims were generated from the building's DPE, without a rating measured for the flat itself (29% in mainland France).
- 8.6% of homes with a DPE in Reims are on district heating (4.1% in mainland France).
- 25% of homes with a DPE in Reims have shared (collective) heating (15% in mainland France).
Energy and climate ratings
Among 50,312 valid DPEs of homes (excluding generated DPEs) in Reims, rating D is the most common; 37% reach ratings A to C.
If the homes with a DPE in Reims had the same mix of building age and type (house, flat) as mainland France, the F+G share would be 9.7% (-0.5 pt versus the observed figure).
By floor area, the F+G share among homes with a DPE in Reims ranges from 6.5% (70-99 m²) to 16% (25-39 m²).
For 22% of homes with a DPE in Reims 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).
11% of homes with a DPE in Reims 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 (5,661 homes; 12% in mainland France). For them, a small measurement gap or a minor work can move the letter.

DPEs generated from the building’s DPE
55% of valid DPEs (60,740) — against 45% in the département and 29% in mainland France — were produced from the building's DPE: their rating was not measured for the flat itself. They are shown separately: their ratings are not mixed into the figures above.

G, F and E ratings: the decent-housing timetable
1,693 homes with a DPE (excluding generated DPEs) in Reims are rated G, i.e. 3.4% of homes with a DPE (4.4% 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).
3,446 homes with a DPE (excluding generated DPEs) in Reims are rated F, i.e. 6.8% of homes with a DPE (7.5% 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).
10,103 homes with a DPE (excluding generated DPEs) in Reims are rated E, i.e. 20% of homes with a DPE (21% 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 5,098 F- or G-rated homes with a DPE (excluding generated DPEs) in Reims whose DPE is still valid on that date, whose published class is reproduced and whose scale could be read, 20% 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
Natural gas comes first: 53% of homes with a DPE in Reims rely on it for heating, and 25% have shared heating.
By heating energy, the share of F- or G-rated homes in Reims ranges from 2.1% for homes heated by district heating to 72% for those heated with heating oil; it is 10% with electricity.
In the 2022 census, INSEE counts 28% of main residences mainly heated by electricity in Reims; among homes with a DPE, the share is 37%.
Of the 4,307 homes with a DPE in Reims heated by a district network, 80% declare their network's identifier. The main ones: “CROIX ROUGE” (5106C), 63% of connected homes (0.052 kg CO₂/kWh direct, 0.069 life-cycle); “VY'ENERGIE” (5103C), 9.7% of connected homes (0.012 kg CO₂/kWh direct, 0.032 life-cycle); “ST RÉMI” (5108C), 4.4% of connected homes (0.098 kg CO₂/kWh direct, 0.112 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, Reims averages 1.9 days a year above 35 °C and 1.5 nights above 20 °C; projections for 2050 point to 5.7 and 8.2.
The DPE includes a "summer comfort" section. In Reims, 92% of homes with a DPE fill it in; of these, 26% 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 Reims is €895 a year for a flat (201 kWh of primary energy per m²) and €1,665 for a house (208 kWh/m²). Per unit of floor area, the median cost of a flat is €20 per m² a year (€19 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.

Works proposed by DPEs
21% of DPEs of F- or G-rated homes in Reims include a first costed package of works. Its median cost ranges from €4,250 (low estimate) to €8,250 (high estimate). These are the ranges entered by assessors, not quotes.
Prices and green value
Median price in Reims over 2021-2025 sales: €2,731 per m² for a flat (11,557 sales), €2,676 for a house (2,814 sales) — DVF statistics (Etalab).
In our "DPE discount city by city" study (house sales matched to their DPE), F- or G-rated houses in Reims sold for 9.1% less per m² than D-rated houses.
Estimated advertised rent in Reims, charges included, all DPE ratings combined: €13.10 per m² per month for a flat (prediction interval €10.37 to €16.55), €11.77 per m² per month for a house (2025 rent map).
Co-ownerships and collective DPE
The national register of co-ownerships lists 2,956 co-ownerships in Reims (Q3 2025 file, all construction periods), with 49,620 residential units in total: 9 have more than 200 units used as homes, offices or shops, 213 between 51 and 200, and 2,734 with 50 units or fewer. Of those with a known period, 47% were built before 1949 and 9.1% 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 3,667 valid building-level DPEs in Reims, single-owner buildings included; one building may have several.
72 co-ownerships in Reims are flagged in the register as having received an Anah grant for owners' associations, and 65 are in a priority urban-policy neighbourhood (QPV).

DPEs quarter by quarter
130,219 DPEs of homes have been issued in Reims since July 2021. The F+G share among each quarter's DPEs went from 33% (2021, Q3) to 9.1% (2026, Q2) — a shift that also reflects which homes get assessed, and changes to the calculation rules.
