Careful: the IRAV is not always what you can be charged

For rent updates between 8 October 2026 and 31 December 2027, Royal Decree-Law 29/2026 (in force, awaiting ratification by Congress) provides that, absent a new agreement between the parties, the increase cannot exceed 2%. So the IRAV above is the index, not the amount a landlord can charge in that period when it exceeds 2%. In addition, if your rent already exceeds the maximum under the reference-price index system, no increase is allowed at all. Updated on 21 October 2026.

Residential leases only. The result is a maximum: if your contract sets a lower index, that one applies.

Which IRAV applies to your contract?

The LAU (art. 18.1) takes as its reference "the latest index published on the contract's update date". The law writes that rule for the CPI and the IGC, and Law 12/2023 made the IRAV the limit for the purposes of that same article.

The reading used by the major guides is that the latest IRAV published on your contract's anniversary applies. No statute repeats this word for word for the IRAV, so it is an interpretation, not a quotation of the law.

Royal Decree-Law 8/2026 was in force between 22 March and 29 April 2026 and capped that period's increase at 2%; Congress did not ratify it, and it stopped applying from 30 April 2026.

Since 8 October 2026 Royal Decree-Law 29/2026 has been in force, awaiting ratification: for updates falling due up to 31 December 2027, the increase is whatever the parties newly agree and, absent an agreement, cannot exceed 2%. If the IRAV is higher than 2%, the IRAV is the index, but not the figure that can be applied to you.
