MaPrimeRénov': what you need to know before you start

MaPrimeRénov' can fund a significant share of an energy renovation. But its rules change regularly, and a mistake in the timing can cost you the grant. Here are the points to check before signing anything.

Who is eligible?

MaPrimeRénov' is open to owners, whether they live in their home or let it, as well as to usufructuaries. The home must have been built at least 15 years ago and be occupied as a main residence for at least eight months a year. For a whole-house renovation, an owner-occupier undertakes to continue living there for three years after the grant is paid. The amount depends on the household's income, divided into four categories: very low, low, intermediate and higher. In the Gironde, as everywhere outside the Île-de-France region, a couple falls into the "intermediate" category, for example, up to a reference taxable income of €45,842, according to the thresholds in force on 1 January 2026.

Two ways to benefit

MaPrimeRénov' funds either a whole-house renovation or individual measures. In 2026, the individual measures route mainly funds a change of heating system: heat pump, connection to a heating network, removal of an oil tank, through a fixed amount. Households with higher incomes are not eligible and turn to energy saving bonuses instead.

The whole-house renovation route is open to all households, for homes rated E, F or G on the energy performance certificate. The programme must include at least two insulation measures (walls, windows and doors, floors or roof) and improve the rating by at least two classes. In a detached house, it must neither install nor keep oil, gas or coal heating. The conditions, ceilings and rates are set by the State and change regularly: the exact rules should be checked at the time of the project on the official website france-renov.gouv.fr.

How much? The rates for a whole-house renovation

The grant covers a percentage of the cost of the work, up to a ceiling on expenditure:

The percentage depends on the household's income:

• Very low income: 80%;
• Low income: 60%;
• Intermediate income: 45%;
• Higher income: 10%.

Energy saving bonuses are automatically included in the application, and the total of all grants cannot exceed a share of the cost of the work including VAT, from 50% to 100% depending on income.

Mon Accompagnateur Rénov'

For a whole-house renovation, support from an approved Accompagnateur Rénov' (renovation adviser) is compulsory. They carry out an audit, help define the programme of work and follow the application. Their service is covered up to €2,000 incl. VAT, from 100% for very low-income households to 20% for higher incomes. Before any application, a first appointment with a France Rénov' adviser, free of charge, is compulsory: the certificate of this appointment must be attached to the application.

The steps, in order

1. Appointment with a France Rénov' adviser, who checks your eligibility.
2. Audit and programme of work with your Accompagnateur Rénov'.
3. Quotes from RGE-certified firms, then submission of the application online.
4. Work, only once the application has been accepted.
5. Submission of the invoices and payment of the grant; an advance is possible, subject to conditions, for very low and low-income households.

The rules never to forget

• Use RGE-certified professionals (recognised as environmental guarantors) for the subsidised work.
• Keep detailed quotes and invoices, which are used for the payment of the grant.
• Beware of cold calling: telephone canvassing for energy renovation is prohibited, and no official body will call you to sell you work.
• Allow for delays: in 2026, applications only reopened on 23 February, after the budget was passed. The processing time must be built into the project schedule.

Other grants to combine

MaPrimeRénov' can be combined with local grants, the zero-interest eco-loan and, depending on the route, energy saving certificates (energy saving bonuses). The rules for combining them depend on the route chosen: a France Rénov' adviser will help you build the financing plan.

How we support you

We work with you to build a coherent programme of work (insulation, windows and doors, heating, ventilation), coordinated with the energy audit and the grant timetable. On a project such as the loft insulation in Bidart, the order of the work matters as much as the quality of each element.
