Energy renovations per year: 500,000 high-performance renovations a year
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.
« Sortir un million de personnes chaque année de la précarité énergétique en atteignant 500 000 rénovations performantes par an via MaPrimeRénov’. »1Translation by the editorsLift one million people out of fuel poverty every year by reaching 500,000 high-performance renovations a year via MaPrimeRénov’.

per year, cost to the public accounts. Budget 2027 dossier (26 August 2026, p. 8): « La rénovation des logements en augmentant MaPrimeRénov de +1,4 Md€ pour rétablir les 5 milliards prévus initialement en 2024 » [“Housing renovation by increasing MaPrimeRénov by +€1.4bn to restore the 5 billion initially planned in 2024”]

No external costing of this position recorded to date.
Our calculation
−€11bn* (outside the range measured by the source: linear extrapolation)
per year for the public accounts, new spending, range −€15bn to −€4.9bn.
* Outside the range measured by the source: linear extrapolation (measured range: 91,374 homes only).
The calculation
- Major renovations assisted per year: (500,000 − 91,374) ÷ 100,000 = 4.09 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. The « rénovations performantes » [“high-performance renovations”] are read as large-scale renovations. The amount is the cost of the target of 500,000 renovations per year once reached, at the current average public aid for a large-scale renovation (€26,100; lower bound: €11,800, average aid in co-owned buildings). This is not the budget announced by Les Écologistes: +€1.4bn for MaPrimeRénov' in 2027 (Budget 2027 dossier), removed on that account from their €10bn envelope under the “Additional public investment, per year” lever.
Coefficient calculated by the editors from Chiffres clés de l'Anah 2024 (DREAL Corse): the position is marked as an assumption by the editors.
Figure announced by the candidate: no gap calculated: the announcement covers a different scope or a different year.
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.
