An evaluation of MaPrimeRenov effectiveness using newly released panel data from the 2023 heating season across French residential stock.
France’s flagship renovation subsidy scheme, MaPrimeRenov, reached 710,000 households in 2023 — a 23% increase on the 2022 baseline. Yet aggregate renovation rates remain below the 2.5% annual threshold required to meet the 2030 decarbonisation trajectory outlined in the NECP (National Energy and Climate Plan). The gap between subsidy uptake and structural renovation depth is widening.
This analysis draws on ANAH (National Housing Agency) administrative data, Banque de France household energy expenditure surveys, and the Observatoire de la Renovation building stock model to assess the depth, geographic distribution and energy efficiency outcomes of current policy incentives. A parallel review of the mandatory performance thresholds introduced by the EPBD 2024 recast frames the national-level findings within the evolving EU compliance landscape.
Key Findings
Deep renovations — defined as works achieving at least two EPC class jumps — accounted for only 14% of all subsidised projects in 2023, against a target of 35% by 2025. Single-measure interventions, primarily insulation of attics and floors, dominate the subsidy pipeline and deliver limited long-term carbon performance.
Regional disparities are pronounced: Ile-de-France and PACA account for 38% of disbursements but only 21% of the national housing stock, reflecting higher per-m² costs in dense urban markets rather than disproportionate renovation activity. Inland regions with the worst EPC profiles — Hauts-de-France and Grand Est — receive proportionally fewer subsidies despite higher renovation need.
Contractor capacity emerges as the binding constraint in rural departments. In 23 of 96 metropolitan departments, average waiting times for RGE-certified (Reconnu Garant de l’Environnement) contractors exceed seven months, discouraging householders who cannot bridge financing gaps over extended timelines.
Financing Structure Analysis
The MaPrimeRenov grant interacts with three other instruments: the Eco-PTZ interest-free loan, Anah’s Habiter Mieux Sérénité income-linked programme, and local authority top-ups. Stacking these instruments can theoretically cover 70-90% of deep renovation costs for lower-income households, but administrative complexity creates a strong self-selection effect towards single-measure applications.
Average subsidy per project in 2023 was €3,840, against estimated deep renovation costs of €28,000-€55,000 per dwelling. The financial gap between available public support and comprehensive renovation investment is not bridged by current instruments for the median household.
Policy Implications
The evidence suggests MaPrimeRenov’s flat-rate structure insufficiently rewards deep renovation pathways. A tiered co-financing model, analogous to the German BAFA Bundesförderung scheme, would better align financial incentives with thermal performance outcomes. The Building Performance Institute Europe has consistently argued that output-based subsidies tied to measured energy savings, rather than input-based subsidies tied to technology installation, achieve higher renovation depth at comparable public cost. See the BPIE Renovation Wave analysis for a cross-EU comparison.
The 2025 MaPrimeRenov revision introducing mandatory multi-measure requirements for the worst-performing homes (classes F and G) represents a structural correction, but implementation will require significant capacity-building in rural contractor networks before the policy shift translates into measurable renovation depth improvements.
Outlook
The trajectory to 2030 depends less on headline subsidy volumes than on the structural depth of the works financed. The evidence reviewed here points to three priorities for the next phase of MaPrimeRenov: shifting the incentive structure towards multi-measure deep renovations, expanding the pool of RGE-certified contractors in underserved rural departments, and simplifying the stacking of complementary instruments so that lower-income households are not deterred by administrative complexity. Without coordinated progress on all three, the gap between subsidy uptake and measured energy savings is likely to persist. Aligning grant levels with verified post-works performance, rather than with the technology installed, would give the scheme a clearer line of sight to the national decarbonisation targets it is intended to serve.
