Challenging a Rent Increase under the Renters Rights Act 2025

Rent, Deposits & Increases England 5 min read · published September 14, 2026 Flag of England

If your landlord proposes a higher rent, you may be able to question it rather than accept it immediately. This guide explains how tenants and renters in England can check whether a rent increase follows the tenancy agreement and the law, understand the changes introduced by the Renters' Rights Act 2025, and prepare a challenge. It covers notices, timing, evidence, negotiations and applications to the First-tier Tribunal (Property Chamber). The correct route depends on your tenancy type and when the increase takes effect, so keep paying the existing rent while you check your position and obtain advice if needed. Acting promptly can help you avoid arrears and protect your housing.

What the Renters' Rights Act 2025 changes

The Renters' Rights Act 2025 introduces major changes to private renting in England, including the ending of most assured shorthold tenancies and section 21 evictions. The reforms are being brought into force in stages, so check the current commencement date and official guidance before relying on a new rule.[1]

For rent increases, the important practical points are the notice used, the frequency of increases and whether the proposed rent is realistic for similar homes. During the existing section 13 regime, a landlord of an assured periodic tenancy generally uses the prescribed notice and must follow the statutory timing rules. A tenant can ask the tribunal to decide the market rent if the legal conditions for an application are met.

The Act does not automatically make every proposed rent increase unlawful or give every tenant an automatic reduction.

Check the increase before challenging it

Start by identifying your tenancy and reading the rent clause. A fixed-term tenant will usually need to check whether the agreement permits an increase during the term. A periodic tenant should check the notice period, the proposed start date and whether the landlord has used the correct prescribed form. The current GOV.UK guidance explains the general process for rent increases in England.[2]

  • Compare the new rent with your current rent and with similar local properties.
  • Check the notice form, service method and proposed date against your tenancy agreement.
  • Calculate the deadline for any tribunal application before the new amount is due.
  • Keep the tenancy agreement, rent records, messages, photographs and comparable listings.
Keep paying the undisputed rent on time while you obtain advice about the proposed increase.

Official notices and forms

Form 4B: notice of a proposed rent increase

Where the current statutory procedure applies, the landlord may need to serve Form 4B, the prescribed notice proposing a new rent under section 13 of the Housing Act 1988. The tenant should check that the property, current rent, new rent and effective date are correct. For example, if a notice says the increase starts before the required notice period ends, keep the notice and raise that point in writing rather than ignoring it.

First-tier Tribunal application form

A tenant who wants an independent decision normally uses the First-tier Tribunal (Property Chamber) application form for a rent determination under section 14 of the Housing Act 1988. The tribunal's current form and guidance should be used because forms and filing instructions can change. For example, if your landlord proposes £1,500 a month but comparable evidence supports £1,250, you can submit the notice, agreement and evidence with the application.

Form numbers can change as the new tenancy system is introduced. If your tenancy has moved into the Renters' Rights Act 2025 regime, use the prescribed notice and tribunal instructions in force on the date of the increase rather than assuming that an older form remains correct.

A tenant receiving a rent notice should record the date of service before deciding whether to negotiate or apply to the tribunal.

How to challenge the proposed rent

Ask the landlord to review it

Write calmly and explain why the amount appears unreasonable or procedurally defective. Include a short comparison with similar properties, identify any error in the notice and suggest an affordable figure. Negotiation can resolve the issue without a hearing, but do not sign a new agreement or accept a revised rent without understanding its effect.

Prepare evidence

Useful evidence may include several genuinely comparable local listings, details of condition and facilities, the tenancy agreement, rent payment records, the notice and communications with the landlord. Evidence should compare similar properties rather than simply show that your household cannot afford the increase. If serious repairs affect value, report them in writing and keep the repair history; rent and repair disputes can overlap but are not always decided in the same process.

  • Save dated copies of the notice, agreement, receipts, messages and comparable rental evidence.
  • Record unresolved repairs or habitability problems with dates and photographs.
  • Show the current rent, proposed rent and the figure you say is reasonable.

Apply to the tribunal

The First-tier Tribunal (Property Chamber) can determine the market rent in cases within its jurisdiction. Follow the current application guidance, provide the requested documents and pay any stated fee unless an exemption or remission applies. The tribunal may ask for further evidence or list a hearing. Continue meeting your existing rent obligations unless an official decision or agreement changes them.

Do not stop paying rent simply because you have challenged an increase.

Relevant legislation in England

The Housing Act 1988 contains the main statutory framework for assured tenancies, including the section 13 rent increase procedure and the section 14 tribunal power. The Rent Act 1977 remains relevant to certain regulated tenancies, which have different rules. The Renters' Rights Act 2025 changes the private rented sector framework, but particular provisions apply only when commenced, so check the legislation and official implementation guidance.[3]
