France creates a temporary cash grant for small construction and public works businesses that used non-road diesel in May 2026. Eligible firms can receive 20 euro cents per litre invoiced between 1 and 31 May 2026, capped at 4,000 euros per business. The aid is limited to French tax-resident private businesses in listed construction activities, with no more than 20 employees and within SME financial thresholds. Applications must be filed online through impots.gouv.fr between 8 June and 3 July 2026, with May fuel invoices, a required spreadsheet, bank details, and de minimis aid declarations. Businesses may have to repay the aid if their profit position later shows they were not economically weakened enough.
