Frequently asked questions
When can I challenge a rent increase?
You can challenge a rent increase if it was not served using the official Section 13 notice, if the notice period is less than 2 months, or if you believe the increase is above the market rent. You can apply to the First-tier Tribunal to challenge the amount within 3 months of the notice being served.
How much notice must my landlord give?
Under the Renters' Rights Act 2025, landlords must give a minimum of 2 calendar months' notice for a rent increase. They can only raise rent once per year.
What form must be used?
Rent increase notices must be served using the official Section 13 notice (Form 4). Any other method — including letters, emails, or verbal notification — is invalid.
Can I challenge the amount of the increase?
Yes. If you believe the proposed rent is above the market rent for your property, you can apply to the First-tier Tribunal (Property Chamber) within 3 months of the notice being served. The tribunal can reduce, confirm, or dismiss the increase.
