Challenge Rent Increase Letter: Free Template and What to Include

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.

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 an assured tenancy, reference the right to refer a Section 13 rent increase to the First-tier Tribunal (Property Chamber), and that the application must be made before the date the new rent is due to start
• 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 — a Section 13 notice (form 4A) giving at least 2 months' notice, no more than once a year, even if you have agreed to the increase. 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?
No — private tenancies in England no longer have fixed terms, and a landlord can only increase the rent once a year using a Section 13 notice, not through a rent review clause.

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.

Dear [Landlord or Letting Agent Name],

Subject: Proposed rent increase for [Your Address]

I am writing about your notice dated [date] proposing to increase my rent from £[current rent] to £[proposed rent] a month from [date].

I believe this increase is too high. Similar homes nearby are letting for £[lower figure] to £[higher figure] a month. The property also has problems that affect its value:
• [e.g. The living room window does not close fully]
• [e.g. The hallway carpet is badly worn]

[England, assured tenancy: A rent increase must be proposed with a Section 13 notice (form 4A) giving at least 2 months' notice, no more than once a year. [If it applies: Your notice does not follow this process because [reason].] If we cannot agree, I can refer the increase to the First-tier Tribunal (Property Chamber) before the new rent is due to start.]

I am a reliable tenant who pays on time and looks after the property. Please reconsider the increase. I would accept a rent of £[your figure] a month.

Please reply by [date].

Yours sincerely,
