The hunt for thermal colanders. The enactment of the Climate and resilience law, on August 24, 2021, marks the end, in the medium and long term, of housing qualified as thermal sieves. Those with the lowest scores in the energy performance diagnosis (DPE) will no longer be able to be rented as they are from 2025. A governmental pressure on owners who are reluctant to carry out energy renovation work. In Lille, this could concern 25% of the accommodation listed by Ademe.
“From 2025, it will be prohibited to rent the least well insulated thermal colanders (classified G), and from 2028 for the rest of the colanders (classified F)”, provides for the new law. At a later date, 2034, it is E-rated housing that will in turn be affected.
The initial bill also provided for implementation from next January 1, but this will not be the case. On the other hand, on this date, it will no longer be possible for owners of G-class properties to increase rents without having carried out insulation work. “It’s always better than doing nothing, even if such a measure should have been taken a long time ago”, recognizes Jean-François Liem, specialist in carrying out DPE in Lille.
A quarter of DPEs in Lille are E, F or G
In Île-de-France, 750,000 homes bear the labels E, F or G, i.e. one in two properties will be prohibited for rental within 11 years. according to Daily, the daily life of diagnosticians. In Lille, we seem less badly off, with a quarter of the dwellings concerned, if we refer to the Ademe data. Of the 49,661 dwellings having passed an ECD between 2012 and 2021, 1,114 are G, 3,793 are F and 7,735 are E. The specialist agrees, bad students are a minority in Lille. “Of the 11 studios in Old Lille that I have just diagnosed, only one is in G and 5 in F. But it is a building that has not been renovated,” he says. If he looks more globally, diagnoses F and G represent only 15% of his total benefits.
This leaves two years for the owners of the worst thermal colanders to carry out work so that their goods are not considered “indecent under the law”. It’s long and short at the same time for Jean-François Liem who deplores the often very high renovation costs. “Between aid, bonuses, subsidies and zero-rate loans, the cost of work can be reduced by 40% for condominiums,” says the city. For individuals, subject to a means test, public subsidies for the rehabilitation of substandard housing can even go well beyond that.
