Challenge Rent Increase Letter Template & Generator

If you need to challenge an excessive or improperly served rent increase notice, a written letter is the recommended first step — it creates a clear record and shows you're pursuing the matter formally. Below is what a strong challenge rent increase should include, plus a free tool to generate yours.

What this letter needs to cover

• Identify the proposed increase and current rent
• Set out reasons it is excessive based on comparable local rents and the condition of the property
• For assured shorthold tenancies reference the right to refer a section 13 increase to the First-tier Tribunal (Property Chamber)
• Request the landlord reconsider or withdraw the proposed increase

When a rent increase can be legally challenged

Rent increases must follow the correct legal process — the right form (commonly a Section 13 notice for periodic tenancies), the correct notice period, and can't simply be imposed mid-fixed-term without your agreement unless your tenancy agreement specifically allows it. An increase that skips these requirements, or is significantly above local market rates, can be challenged.

What to include before you send it

• Confirmation of the notice received and why you believe it's invalid or excessive
• Reference to the correct legal process that should have been followed
• If disputing the amount rather than the process, evidence of comparable local rents
• A clear statement of your position, and whether you're referring the matter to a tribunal

Referring an excessive increase to the tribunal

If you receive a valid Section 13 notice but believe the proposed rent is above the going market rate, you can refer the matter to the First-tier Tribunal (Property Chamber) before the increase takes effect — the tribunal can set the rent at a fair market level, which can be lower, but generally can't set it higher than what was proposed.

Frequently Asked Questions

Can my landlord increase rent as much as they like during a fixed-term tenancy?
Generally no — unless your tenancy agreement has a specific rent review clause, a landlord typically cannot increase rent during a fixed term without your agreement.

Is there a limit on how often rent can be increased?
For periodic tenancies using a Section 13 notice, increases are generally limited to once every 12 months, though check your specific tenancy type and agreement.
