Comparing financing solutions and anticipating recent regulatory constraints is key to the success of a real estate or renovation project. Since September 1, 2026, the rules of MaPrimeRénov’ have been significantly revised, altering the economic calculations for many homeowners. This article assesses the concrete impact of these changes on the choice of work, the timeline for submitting applications, and the available credit options.
MaPrimeRénov’ after the September 2026 decree: what remains eligible
Decree No. 2026-822 and the order of August 25, 2026, have refocused the “by gesture” aspect of MaPrimeRénov’. Several items that were previously subsidized, including external insulation as a standalone gesture, are no longer eligible for assistance since September 1, 2026.
The works still covered can be counted on one hand. Here are the gestures that remain eligible according to the Banque des Territoires:
- The installation of certain heat pumps, which now accounts for the majority of funding requests by gesture.
- Connection to a district heating network, a relevant option in densely populated urban areas where the network already exists.
- The removal of an oil tank, often coupled with the replacement of the heating system.
- The energy audit, subject to resource conditions, for homeowners considering a subsequent comprehensive renovation.

Submission date for MaPrimeRénov’ application: the calendar trap
The most underestimated point of this reform concerns the submission date of the application, not the date of the quote. According to an analysis by Selectra published on September 7, 2026, the new rules apply to any application submitted from September 1, 2026, even if the quote was signed several months earlier.
This mechanism creates a concrete gap. A homeowner who signed an insulation quote in July 2026 but submitted their application in September will be subject to the new regime. Since the gesture is no longer eligible, the funding is lost.
Anticipate submission to secure funding
The lesson is clear: any renovation project must incorporate the administrative submission as a step as critical as choosing the contractor. Waiting until the end of the project or the receipt of invoices to compile the application risks outright rejection.
This constraint weighs particularly heavily on landlord homeowners renting energy-inefficient properties. For them, the funding window has narrowed while the obligation for energy performance remains in effect.
Work credit and home loan: comparison of financing options
When public aid no longer covers a work item, resorting to credit becomes the adjustment variable. Several formulas coexist, with very different logics depending on the amount and duration of the project.
| Type of financing | Mandatory allocation | Typical duration | Particularity |
|---|---|---|---|
| Home loan (including work) | Yes | Long (aligned with the main loan) | Generally lower rates, but commits for the total duration of the loan |
| Allocated work credit | Yes | Medium | Funds are disbursed upon presentation of invoices |
| Unallocated personal loan | No | Short to medium | Freedom of use, higher rates |
| Zero-interest eco-loan | Yes (energy renovation) | Up to 20 years | No interest, subject to energy performance conditions |
| Home savings loan (PEL/CEL) | Yes | Variable | Depends on the age of the savings and the contractual rate |
The zero-interest eco-loan remains the most advantageous lever for energy renovation work, as it eliminates the cost of credit. However, it requires eligible works to be carried out and validated by a certified professional, which effectively excludes purely aesthetic or functional modifications.
Combining multiple sources for the same project
There is nothing preventing the combination of a zero-interest eco-loan for insulation or heating with a personal loan for bathroom renovation. This segmented approach allows for reserving the zero rate for eligible items and limiting the overall cost of financing.

EPC and electric homes: a reclassification to verify
The energy performance diagnosis has been recalibrated for homes heated by electricity. Old EPCs that are still valid can now be subject to a free new label certificate via the Ademe Observatory.
This reclassification can shift a home from an F or G label to a higher class, without any work. For a landlord homeowner, this radically changes the situation: a property that seemed to require heavy renovation may now meet rental thresholds.
Check before renovating
Before committing a renovation budget on a home heated by electricity, the first step is to request this certificate. If the new label is sufficient to make the property rentable, priority works can be redirected towards comfort or enhancement rather than energy compliance.
The landscape of financing and regulation is now evolving at a semi-annual pace. The combination of EPC verification, early submission of aid applications, and tailored financial arrangements constitutes the triptych to master for any real estate project launched at the end of 2026.
