Aid in France for 2025
MaPrimeRénov’ – By Action
This aid covers insulation, heating, or hot water. The amount varies depending on your income and the type of work considered. The scale also adapts to your socio-economic category.
MaPrimeRénov’ – Major Renovation
You can benefit from up to 90% coverage if you carry out at least two thermal upgrades. However, a “Rénov’ Accompanist” is mandatory to validate your project.
Other schemes in France
- Éco-PTZ: zero-interest loan up to €50,000, cumulative with MaPrimeRénov’. Strict conditions apply.
- Advance renovation loan: repayable according to each bank’s specific criteria.
- Tax exemptions: some municipalities offer a temporary property tax reduction for three years, subject to conditions.
Aid in Wallonia (Belgium)
Transitional Grants (2025–2026)
Since February 14, 2025, a transitional system is in place until September 30, 2026. Amounts have been reduced by about –60%, and some income ceilings lowered. Certain grants have also been eliminated.
Mandatory audit and eligibility
A housing audit is required to obtain “Works” grants, except for roof or attic insulation. The final amount depends on your income. Some households may receive up to six times more than others.
Aid in Flanders (upcoming reform)
From July 1, 2025, a new system will apply. Aid will be capped between 35% and 50% depending on income. Very low-income households will benefit from the maximum 50%.
