Energy and climate ratings
Among 75,373 valid DPEs of homes (excluding generated DPEs) in Montpellier, rating C is the most common; 65% reach ratings A to C.
If the homes with a DPE in Montpellier had the same mix of building age and type (house, flat) as mainland France, the F+G share would be 4.1% (+1.4 pt versus the observed figure).
Small homes are the most often poorly rated in Montpellier: 4.0% of assessed homes under 25 m² are rated F or G, against 1.4% for those of 70-99 m².
For 16% of homes with a DPE in Montpellier 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).
14% of homes with a DPE in Montpellier 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 (10,217 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
19% of valid DPEs (17,925) — against 18% 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
434 homes with a DPE (excluding generated DPEs) in Montpellier are rated G, i.e. 0.6% of homes with a DPE (0.6% 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).
1,614 homes with a DPE (excluding generated DPEs) in Montpellier are rated F, i.e. 2.1% of homes with a DPE (2.3% 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).
6,721 homes with a DPE (excluding generated DPEs) in Montpellier are rated E, i.e. 8.9% of homes with a DPE (8.3% 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 1,966 F- or G-rated homes with a DPE (excluding generated DPEs) in Montpellier whose DPE is still valid on that date, whose published class is reproduced and whose scale could be read, 43% 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.

Estimated consumption and cost
The median cost estimated by the DPE in Montpellier is €675 a year for a flat (152 kWh of primary energy per m²) and €1,495 for a house (157 kWh/m²). Per unit of floor area, the median cost of a flat is €17 per m² a year (€16 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.

Of those with a known period, 32% were built before 1949 and 13% 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 2,988 valid building-level DPEs in Montpellier, single-owner buildings included; one building may have several.
