What is a Section 13 notice?

It is the prescribed way to propose a rent increase on a periodic tenancy. Under the Renters’ Rights Act 2025 it is limited to once a year, served on Form 4A with at least two months’ notice.

Can the tenant challenge it?

Yes, at the First-tier Tribunal for a small fee. The tribunal cannot set the rent above the figure you proposed, so a strong comparable base is your best protection.

Are the comparables real?

In this demo they are illustrative. A live build would pull genuine local lettings evidence within a set radius.
