MaPrimeRénov’ has become the flagship program to fund your energy renovations. Since its launch, it has helped many households cut their energy bills while improving the comfort of their homes. But like any evolving program, there are changes to watch.
Starting January 1, 2026, two types of work will no longer be funded through the “geste” track, i.e., when you finance only a single type of work. Wall insulation and biomass boilers are affected. This development may surprise those who had planned these specific projects.
Thus, understanding these changes is crucial to plan your renovations and avoid surprises. If you were considering redoing your walls or installing a wood-burning boiler… It’s best to anticipate the aid and take advantage of it before their withdrawal from the “geste” track.
Wall insulation: an exclusion not to be overlooked
As of January 2026, the government will stop funding wall insulation works individually, whether they’re done from the inside or the outside. These works are nonetheless essential for reducing heat losses and improving energy efficiency.
This exclusion does not mean that insulation becomes impossible or that support disappears entirely. If you undertake a large-scale renovation, combining several works (roofing, windows, heating…), you will still be able to benefit from MaPrimeRénov’. But for those who planned to finance only their walls, you’ll need to revisit plans or anticipate the steps before the deadline.
Biomass boilers: the second exclusion of MaPrimeRénov’
Another major change: biomass boilers, running on wood or pellets, will no longer be eligible for individual funding. The goal is to focus aid on renovations that deliver the most effective overall energy performance.
For households wishing to install this type of boiler, there remains a solution: integrate the installation into a broad renovation project. This allows you to continue to benefit from the aid while optimizing the overall energy efficiency of the home. Don’t start planning the work right away to avoid being blocked by these new rules.
These updates to MaPrimeRénov’ prove that the program keeps adapting and keeps homeowners on their toes. As of January 2026, the government is removing the individual funding for wall insulation and biomass boilers. A decision that could disrupt several renovation projects.
The good news is that there are still options. Plan your work ahead, fold these items into a single, comprehensive project, and explore local alternatives or zero-interest loan programs. The energy transition remains accessible to everyone… provided you plan smartly and don’t get caught off guard by the new rules.
