Rent increase checker

Can my rent go up by this much?

Since 1 March 2026 a rent may be reviewed once in 12 months and raised by no more than 2% or the annual change in the Consumer Price Index, whichever is lower. Enter your rent, when it was last set and what is proposed. The checker shows the most it can be, whether the review is too soon or the notice too short, and what to do.

The RTB's own calculator is the official figure for a review. This checker does not know the market rent for your area, which is the other ceiling, and it does not decide whether a notice is valid.
