The 1 September 2026 MaPrimeRénov' reform: what really changes
The short version
From 1 September 2026, several works can no longer be funded as an isolated "single gesture": to keep a grant, they must be part of a whole-home renovation (accompanied pathway).
What is removed from the single-gesture route
The following works will no longer be fundable on their own after the deadline:
- Wall insulation (external ITE and internal ITI)
- Loft and low-floor insulation
- Window and French-door replacement
- Double-flow ventilation (VMC)
- Replacing a boiler with a pellet model (outside a package)
Crucial point: an application filed before 1 September 2026 is processed under the current rules. It's the filing date that matters, not the works date.
What stays fundable per item
The most efficient low-carbon heating systems remain eligible on their own, notably:
- Air/water heat pump
- Ground-source (geothermal) heat pump
- Solar and thermodynamic water heaters
What to do now
- Estimate your grants today to know what you're entitled to.
- If your works are on the removed list, file before the deadline or switch to the accompanied pathway.
- For a whole-home renovation, the first step is to choose your Mon Accompagnateur Rénov' (MAR): they organise the energy audit, build the file and secure your grants.
Whole-home renovation targets at least a 2-class DPE gain, with a spending cap of €30,000 excl. VAT (2 classes) or €40,000 excl. VAT (3+ classes), and coverage of 10% to 80% depending on income.
