Climate, Fabien Roussel
Energy renovations per year: Up to 900,000 whole-building energy renovations a year in 2032
Direction of change: increase, compared with current law.
The lever. Number of homes renovated each year to reduce their energy consumption, according to the programme's target. Direction rule: ↑ more subsidised renovations.
« L’engagement d’un plan massif de rénovation thermique globale des bâtiments, visant jusqu’à 900 000 rénovations par an en 2032 avec un reste à charge nul pour les ménages les plus modestes. »1Translation by the editorsThe launch of a massive plan for the whole-building energy renovation of buildings, aiming for up to 900,000 renovations a year in 2032 with zero out-of-pocket cost for the lowest-income households.

Our calculation
−€21bn* (outside the range measured by the source: linear extrapolation)
per year for the public accounts, new spending, range −€29bn to −€9.7bn.
* Outside the range measured by the source: linear extrapolation (measured range: 91,374 homes only).
The calculation
- Major renovations assisted per year: (900,000 − 91,374) ÷ 100,000 = 8.09 times “+100,000 major renovations assisted per year”, each a cost of €2.6bn (1.2 to 3.6). Proposed value outside the range measured by the source: linear extrapolation (measured range: 91,374 homes only). A single year measured by Anah (2024: 91,374 major renovations, average aid per dwelling); any other value is a linear extrapolation, flagged as such.
Assumption by the editors. Partial costing. The « rénovation thermique globale » [“comprehensive thermal renovation”] is read as a major renovation, at the pace targeted for 2032 (« jusqu'à 900 000 » [“up to 900,000”]): the amount is that of this pace, at the current average grant for major renovations. Not costed: the zero out-of-pocket cost promised to the lowest-income households, beyond the average grant. Buildings other than housing are not distinguished.
Coefficient calculated by the editors from Chiffres clés de l'Anah 2024 (DREAL Corse): the position is marked as an assumption by the editors.
Current law, sources and limits of the cost schedule
Current law. The main instrument is MaPrimeRénov' (Anah). It comprises an assisted pathway for major renovations, per-measure aid and aid for co-owned buildings. It is supplemented by energy savings certificates (CEE). In 2024: 91,374 major renovations (€2,386m in aid) and 340,801 dwellings assisted in total (€3.29bn). The scheme was suspended from June to September 2025, then reopened on 23 February 2026 after the LFI 2026. The final amount of 2026 appropriations differs between sources (€3.5bn or €4.3bn in Anah commitments) and has not been checked in the act.
Horizon. Direct public aid in a full year. Anah 2024 scale in current euros. Includes neither the CEE (energy saving certificates), funded by energy suppliers, nor the cost of support services.
Limits. Central value: average aid across all major renovations (€2,386m / 91,374 ≈ €26,100). Lower bound: average aid in jointly owned buildings (€11,818). Upper bound: individual supported pathway (€36,271). In 2024, 59% of households aided for a major renovation were very low-income: a higher target would reach better-off households, with lower unit aid but an uncertain take-up rate. Fraud justified the 2025 suspension. A target announced in “renovated” homes is converted into major renovations before applying this cost schedule. Only the 2024 financial year is published by Anah in the sources read (key figures); 2025 volumes are known only from the press: the parameter's domain is limited to 2024.

How to read these amounts. These are static costs and revenues, with no feedback effect, over a full year: nothing on growth, employment or the revenue that economic activity would gain or lose. A higher net cost does not on its own make a worse policy, nor net savings a better one: each programme rests on an economic model (demand-led stimulus, lower compulsory levies, consolidation of the public accounts…) that the cost schedule does not settle. GDP itself measures a volume of activity, not well-being or the usefulness of what is produced. Economic models and feedback effects.
