Your landlord wants more. Challenge it.

Since 1 May 2026, your landlord can only raise the rent once per year using a Section 13 notice on Form 4A, with at least 2 months’ warning. If you think the proposed rent is above the market rate — or the notice is invalid — you have the right to take it to the First-tier Tribunal.

Check your Section 13 notice

Answer four questions to see if the notice is valid.

Did your landlord use Form 4A?

Did you receive at least 2 months' notice?

Is this within the first 12 months of your tenancy?

Was your rent increased in the past 12 months?

We check your notice, build your Form 4 application, and prepare your comparables evidence. The tribunal sets the fair market rent — it cannot be higher than the landlord proposed.

From notice received to tribunal application.

You must apply before the date the increase is due to take effect. Act quickly — we can prepare your application in under an hour.

We verify whether the Section 13 notice complies with the rules: Form 4A used, 2 months' notice given, not within the first year of tenancy, and not too soon after the last increase.

Build your Form 4 application

We generate your Form 4 referral to the Property Chamber, draft your supporting statement, and provide a comparables checklist so you can show the proposed rent exceeds the market rate.

File your application with the First-tier Tribunal before the effective date. We give you a guide to what happens at the determination hearing and how to present your comparables.
