In 2025, rents in Portugal may be updated by 2.16%.

According to Notice no. 23099/2024/2 from the National Institute of Statistics published on 18 October 2024, the annual rent update coefficient for various types of leases in 2025 will be 1.0216.

This coefficient reflects the variation in the Consumer Price Index, excluding housing, for the past 12 months and represents a decrease compared to 2024, which saw an increase of 6.94%.

Under Portuguese law, landlords and tenants can specify the terms of rent adjustment in the lease agreement. In the absence of such stipulation or by mutual agreement, the adjustment is made annually according to the applicable update coefficient.

The landlord should notify the tenant in writing, with a minimum of 30 days' notice, of the updated coefficient and the new resulting rent.
