What is a Section 13 notice?

What it does

Section 13 gives a landlord a route to raise the rent without your agreement and without a term in the tenancy allowing it. They serve a notice on a prescribed form proposing a new rent from a stated date.

The same section gives you the right to refer that proposal to the First-tier Tribunal before it takes effect. Those two things come as a pair: the power to propose exists alongside the right to challenge.

What it does not do

• It does not let a landlord raise the rent by letter, email or text.
• It does not let them raise it more than once in twelve months on this kind of tenancy.
• It does not make the proposed figure the rent. It makes it a proposal.
• It does not apply where the tenancy itself contains a rent review clause, which works differently.

Which form goes with it

A section 13 notice has to be on the prescribed form: Form 4A for most assured tenancies now, Form 4 for notices served before 1 May 2026, and Form 5A or Form 5 for an assured agricultural occupancy.
