Cumul CEE and MaPrimeRénov: optimize your heating works in 2025

In a context where energy transition is more than ever a priority, aid programs for renovation, such as the combination of Energy Saving Certificates (CEE) and MaPrimeRénov, present major opportunities for homeowners wishing to undertake heating work in France. In 2025, these aids have been adapted and refocused to ensure better support for households, providing them with financially accessible solutions while considering the growing environmental requirements. Therefore, if you are considering renovating your heating system, it is essential to fully understand these schemes, their eligibility criteria, and especially how to maximize them to significantly reduce the cost of your work.

Understanding MaPrimeRénov and Energy Saving Certificates

In 2025, MaPrimeRénov remains one of the most sought-after aids for energy renovation work. This scheme, administered by Anah (National Agency for Housing), is part of a logic of support for homeowners wanting to carry out major renovations in their homes. The work must always aim for a significant energy gain, as measured by the Energy Performance Diagnosis (DPE).

The Energy Saving Certificates (CEE), on the other hand, are another major lever to encourage homeowners to undertake renovations. Funded by energy suppliers such as Engie and EDF, this scheme allows homeowners to benefit from bonuses in exchange for work that reduces the energy consumption of their homes.

The Evolutions of MaPrimeRénov in 2025

MaPrimeRénov has been redefined to meet the expectations of an audience keen to optimize its energy consumption while undertaking significant work. Since its inception, this aid has been structured to directly target the most impactful renovations. To benefit from MaPrimeRénov, homeowners must now ensure that their projects allow for an improvement of at least two performance classes on their DPE. Thus, for example, moving from an F class to a D class. This criterion ensures a judicious use of public funds by the state.

In 2025, the maximum coverage amount has been modified according to income levels, ensuring greater equity. The poorest households will thus benefit from the most generous aid, with financing reaching 80% of the work undertaken. This aid is also accessible for work carried out as part of a comprehensive renovation, encouraging substantial improvements.

Combining Aids: A Winning Strategy

To optimize the financing of your renovation work, combining MaPrimeRénov with CEE is a relevant means. Although it is not possible to combine these aids for the same type of work, households can turn to single-action interventions to access CEE bonuses. This means that a homeowner wishing to replace an old boiler can also benefit from MaPrimeRénov for other work in their home.

Here are some examples of work eligible for CEE:

• Attic insulation

• Replacement of windows with double glazing

• Changing the heating system (e.g., installation of a heat pump)

At the same time, CEE bonuses are also indexed to the type of work carried out. For instance, replacing an oil boiler with renewable energy equipment such as a pellet boiler is strongly encouraged and may give rise to a financial bonus.

The Different Types of Eligible Work and Their Impacts

It is important to familiarize yourself with the range of work eligible for financial support. In 2025, you can choose between large-scale works or more targeted interventions. What are the works that can benefit from these subsidies?

Insulation Work

Insulation is the priority for renovation projects as it minimizes heat loss. Whether it is attic insulation, wall insulation, or floor insulation, these interventions allow for significant savings on your heating bills. The CEE amounts for attic insulation vary, for example, depending on the type of materials used and the area to be insulated.

• Attic insulation: up to €15/m²

• Wall insulation: up to €20/m²

Replacement of Heating Systems

Changing an old heating system for an energy-efficient model is essential. Modern boilers from brands such as Frisquet, Atlantic, or Saunier Duval offer improved efficiencies and reduced consumption. Households can benefit from bonuses of up to €5,000 for the installation of high-performance energy boilers, such as biomass boilers.

Improvements in Hot Water Production

Work aimed at optimizing the production of domestic hot water can also benefit from aid. Whether through the installation of thermodynamic boilers or solar equipment, these products significantly reduce energy costs. In 2025, a high-performance heating installation coupled with solar systems can lead to interesting savings.

Anticipating Remaining Costs: A Crucial Step

Although there are many forms of aid, it is imperative to remember that combining these schemes does not completely eliminate the remaining costs. Thus, each household will have to anticipate this amount, which will depend on the extent of the works carried out and the energy improvement achieved.

The Capping Mechanism

The capping mechanism regulates the maximum amount of aid that a household can receive based on its income and the ceiling of eligible expenses. For example, a very modest household can expect total reimbursement of eligible expenses, while a wealthier household will have to pay a significant portion of the costs, often exceeding 10% of the expenses.

• Very Modest Households: 100% of the ceiling

• Modest Households: 80% of the ceiling

• Wealthy Households: 50% of the ceiling

Preparing for the Unexpected

In addition to the issue of remaining costs, it is wise to plan for potential overruns related to additional work. This can be caused by unforeseen circumstances during the execution of the project, such as structural issues or other unplanned work. By integrating these factors into your financial planning, you will minimize the risks of unpleasant surprises.
