MaPrimeRénov' fraud: 13 defendants in Nanterre for €4.84 million diverted
Thirteen men have been tried since 9 June in Nanterre for filing MaPrimeRénov' applications in the name of individuals without their consent. The damage is estimated at €4.84 million.
Trial in Nanterre: organised network diverts €4.84 million via MaPrimeRénov'
The Nanterre criminal court opened on Monday 9 November 2026 the trial of thirteen men accused of orchestrating massive fraud involving energy renovation subsidies, according to jechange.fr. The proceedings are set to continue until Friday 13 November. The total damage is estimated at €4.84 million, for offences committed between 2021 and 2024.
The central mechanism is described unambiguously by the prosecution: MaPrimeRénov' applications were filed in the name of individuals who had never sought any assistance. The subsidies were not paid to the application holders, but to accounts controlled by the network. The victims were unaware of these procedures, sometimes only learning of them upon receiving an unexpected letter or when a check took place.
A multi-layered network spanning France and Israel
The prosecution describes a structured organisation. Masterminds drew up fraudulent applications. Recruiters found nominees. "Money mules", often men in precarious situations, lent their identity to create fictitious companies and open accounts, including abroad. According to the prosecution, one team operated from France and another from Israel.
Subsidies were obtained by means of false quotations, false invoices and false mandates, then passed through shell companies with no real activity. The case comprises a second component, unrelated to renovation: financial investment fraud, carried out in the name of an investment company whose identity had been usurped.
The National Housing Agency (Anah), which manages MaPrimeRénov', has joined the proceedings as a civil party. All thirteen defendants, free under judicial supervision, are appearing on charges of aggravated money laundering; some are also prosecuted for organised fraud and criminal association.
Weaknesses identified by a parliamentarian
This trial is not an isolated case. The mechanism was precisely described in a written question published in the Journal officiel on 22 July 2025, filed by Loiret deputy Constance de Pélichy. An individual discovered, during an on-site inspection, that an application for assistance for a heat pump had been filed in his name, without him having carried out any work or submitted any application. The deputy pointed out three structural weaknesses that allow this type of fraud to go undetected, and noted the absence of a clear pathway for victims. No government response had been published to date.
Fraudsters obtain personal data through several means: a canvasser who requests a tax assessment document under the pretence of verifying eligibility, a fake assistance website, or a copy left during a home visit. The tax assessment document has thus become, according to jechange.fr, a document to be protected in the same way as an identity document, like the tax number targeted by fake emails and SMS bearing tax authority branding.
What victims should do
Victims do not have a single procedure, but official channels exist. The recommended steps consist of contacting Anah to report the identity theft, filing a complaint, and keeping a record of each communication. Anah itself acknowledges that resolving cases of identity theft "requires additional analysis". The complaint receipt and copies of communications make it possible to prove good faith in the event of a subsequent inspection.
This reflex applies beyond MaPrimeRénov': health insurance now offers a feature allowing users to report care never received from their ameli account. Certain home insurance policies also cover costs incurred as a result of identity theft.
Warning signs for individuals
Most victims discover the fraud by chance. However, several situations should lead to checking one's file without delay: receipt of a letter from Anah relating to work not carried out, a visit from an inspector, or the presence of an unknown application in one's personal online space.
For individuals considering filing a MaPrimeRénov' application, jechange.fr recalls that the most effective protection remains to create one's own account and file one's own application before any contact with a canvasser. A genuine professional never needs the tax assessment document to draw up a quotation.
The rules governing the scheme have furthermore evolved in 2026: insulation, windows and pellet stoves are no longer eligible as individual measures since September, and for a heat pump, combining MaPrimeRénov' results in the loss of an alternative subsidy of €9,800 offered from 17 November. Any tradesperson who promises assistance without mentioning these changes deserves thorough verification.
