Which leases does the IRL for Q1 2024 apply to?
- Leases whose rent review clause names Q1, whatever year they were signed.
- For a review dated from 1 June 2024 and before the IRL for Q1 2025 is published, expected in mid-April 2025. On the review date, you always take the latest index published for the lease's quarter.
- Leases signed while it was the latest published index and that name no quarter: it becomes their reference index.
Example: a €700 rent reviewed with the IRL for Q1 2024
You compare the index for Q1 2024 (143.46) with the one for Q1 2023 (138.61):
700 × 143.46 ÷ 138.61 = €724.49, i.e. €24.49 more per month and €293.88 over a year. Only the rent excluding charges is reviewed.
| Current rent excl. charges | Reviewed rent | Difference per month |
|---|---|---|
| €500.00 | €517.50 | +€17.50 |
| €700.00 | €724.49 | +€24.49 |
| €900.00 | €931.49 | +€31.49 |
| €1,200.00 | €1,241.99 | +€41.99 |

An index capped by the "rent shield"
The law of 16 August 2022, extended by the law of 7 July 2023, capped the yearly change of the IRL at 3.5% in mainland France for the indices from Q3 2022 to Q1 2024. The value of 143.46 already includes this cap. The cap was 2.5% in the overseas territories, and a specific rate applied in Corsica: INSEE published separate series for those areas.

The rules to keep in mind
- The lease must contain a rent review clause; without one, the rent stays the same during the lease.
- The increase has to be requested: it is never backdated and is lost after one year.
- The IRL is a cap: you can apply a smaller increase, or none.
- Rent for a home rated F or G on the energy certificate (DPE) can no longer be increased.
The whole process, including the letter to the tenant, is in the guide to rent increases in France.
On your lease anniversary, the new rent is worked out and the French letter to your tenant is ready. Free for one property.
Frequently asked questions
What is the French IRL for Q1 2024?
The rent reference index (IRL) for Q1 2024 is 143.46, +3.50% over one year. It appeared in the Journal officiel on 1 June 2024 (source: INSEE).
Until when can the IRL for Q1 2024 be used?
It applies to rent reviews dated before the IRL for Q1 2025 is published, expected in mid-April 2025. The landlord then has one year after the review date to ask for the increase; after that, the increase for that year is lost.
My lease doesn't name a quarter: does this index apply?
Only if it was the latest IRL published on the day the lease was signed. In that case, Q1 remains the reference quarter for every later review.
