See the IRL series on INSEE's websiteIRL for mainland France. Corsica and the overseas departments have their own index, which these pages do not give.
A newer index is out: IRL for Q3 2026.
Which rents does it revise?
A lease whose reference quarter is Q4 is revised with this index on its revision date, if the index was out by then. The new rent is the current rent × 142.06 ÷ 137.26, the same quarter's index a year earlier, rounded to the cent.
Example: a rent of €800.00 excluding charges becomes €827.98: +€27.98 a month.
A home rated F or G cannot have its rent revised if the lease was signed, renewed or tacitly extended since 24 August 2022 in mainland France.
The review is not automatic: it applies from your request, never earlier, and is lost if not requested within a year of the date the lease sets.
