Your rent review letter, with the right index.
The IRL of the quarter the lease names, the calculation in full, when it applies: a PDF letter ready to send, refused for an F or G home.

A letter template, not advice on your situation. For a dispute, see a commissaire de justice (bailiff) or a lawyer.
The letter is written in French: it goes to the tenant of a French lease, and a French judge would read it if the dispute went further.
With Kivlo
Every year, Kivlo takes care of it.
On the date the lease sets, Kivlo works out the review, prepares the letter and sends it to the tenant once you have approved it. An F or G home is blocked, an unknown class flagged.
- The IRL read from INSEE every day
- Alerts before and on the anniversary
- Electronic registered letter as an option, in credits
New rent To fill in
The rent review, in practice.
When to review
Only if the lease provides for it: once a year, on the date it sets, or else at the end of each year of the lease (article 17-1 of the law of 6 July 1989).
The rent follows the rent reference index (IRL) INSEE publishes every quarter: current rent × IRL of the reference quarter ÷ IRL of the same quarter a year earlier.
Which index
The one for the quarter the lease names, in its latest version published on the review date. If the lease names none, the last index published on the day it was signed.
Mistakes to avoid: taking the latest IRL out rather than the lease quarter's, or claiming a past review.
The deadline and when it applies
You have a year from the review date to ask for it. After that, you are deemed to have waived it for the year gone by.
The review takes effect on the date of your request, never retroactively: send the letter in a way that keeps its date, registered post or delivery against signature.
F and G homes
The rent of a home rated F or G cannot be reviewed (article 17-1 of the law of 6 July 1989, from the Climate and Resilience law).
This holds for leases signed, renewed or rolled over since 24 August 2022 in mainland France, since 1 July 2024 in Guadeloupe, Martinique, Guyane, La Réunion and Mayotte.

The rent review letter: your questions.
No: it is possible only if the lease provides for it, and you have to ask for it. With no request within a year of the review date, you are deemed to have waived that year (article 17-1).
Not beyond a year, and never retroactively: the review takes effect on the date of the request. If you let a year go by, the tool writes the current anniversary's letter, with that year's change only.
The formula works both ways. If the index has not risen in a year, the review gives no increase: the tool makes no letter.
Find it before writing: it is on the energy performance certificate attached to the lease. At F or G the review is forbidden: the tool makes no letter.
The law sets no form, but the review takes effect on the date of your request: keep proof of it. Registered post with acknowledgment of receipt, by post or electronic, or delivery against signature gives it.
Nothing is sent: the PDF is made in your browser. Kivlo sees neither the names, nor the addresses, nor the amounts, and nothing is kept when you close the page.
