Receiving a rent increase notice when you’re already stretched is frightening. Before calling your landlord, agreeing to anything, or starting to think about moving, understand your options.

Under the Renters’ Rights Act 2025 — in force across England since 1 May 2026 — you have more time and more protection than most tenants realise.

In immediate financial difficulty? Skip to financial support options for Universal Credit, Local Housing Allowance, and emergency council funds you can apply for in parallel with the legal route below.

First: you don’t have to accept it immediately

A rent increase notice (Form 4A) gives you at least 2 months before the new rent would take effect. That is 2 months to assess your options, gather information, and, if you choose, challenge the increase. The increase does not take effect automatically until the proposed date, and only if you do nothing before it.

One rule above everything else: Do not miss the deadline. Your right to challenge lapses when the proposed effective date passes. Act before that date.

Step 1: Check whether the notice is valid

Before worrying about the amount, check whether the Form 4A was served correctly. If it has a procedural defect, it has no legal effect. You can apply to the First-tier Tribunal to have it declared invalid, your rent stays the same, and the landlord has to restart the process with a fresh notice.

A notice is invalid if it:

  • Uses the wrong form (the old Form 4, not Form 4A)
  • Gives less than 2 months’ notice
  • Sets an effective date that isn’t the start of a rental period
  • Proposes an effective date within the first 52 weeks of your tenancy
  • Proposes an effective date within 52 weeks of the last increase

Send us the notice on WhatsApp and we can help you work through these points quickly.

If the notice is valid, move to the next step.

Step 2: Check whether the proposed rent is above market

There is no percentage cap on how much rent can increase. But the legal ceiling is open-market rent: what the property could realistically let for to a new tenant today, based on comparable properties nearby.

If the proposed rent exceeds market rent, the First-tier Tribunal will reduce it.

Check comparable properties on Rightmove and Zoopla. Look at:

  • Same area (within 1–2 miles)
  • Same number of bedrooms
  • Similar type, condition, and furnishing
  • Let within the last 12 months

“Let Agreed” listings can help show which homes attracted a tenant, but the displayed figure may still be the asking rent rather than the final agreed amount. Actual comparable tenancy agreements or confirmation from an agent are stronger evidence.

If comparable properties are letting for less than your proposed new rent, you have grounds to challenge. Full guide to what evidence the tribunal uses →

Step 3: Challenge at tribunal

If you want to challenge the proposed rent, apply for an open market rent determination before the effective date. You can apply online or use paper form MR1. This means:

  • Cost: the application normally costs £47, with exemptions for some cases and possible help with fees
  • Protection: Section 21 is abolished, although a landlord can still seek possession on statutory grounds
  • Start date: if the tribunal decides after the proposed date, any new rent will usually begin on the next payment date after its decision

The tribunal assesses open-market rent and cannot set rent above the landlord’s proposed figure. The worst outcome is that you end up paying what was proposed. If the market supports a lower figure, the tribunal reduces it.

What you pay while the case runs

If the tribunal decides after the proposed start date, any new rent will usually begin on the next payment date after the decision. The written decision will state the rent and its start date.

Step 4: Request a hardship deferral

If paying a new rent from the proposed date would cause hardship, ask the tribunal to postpone the payment date.

Give full details of your financial circumstances in the application and explain why paying from the proposed date would cause hardship. It is not automatic.

Step 5: Negotiate directly

You do not have to go to tribunal, and filing an application does not prevent negotiation. You can approach your landlord directly with comparable evidence and propose a figure you can sustain. Filing the tribunal application first strengthens your position. It gives the landlord delay, uncertainty, and your evidence to weigh up.

If you agree a figure, record the agreement clearly. The tenant can ask to withdraw using form Withdrawal 1, but the application ends only when the tribunal consents to the withdrawal.

Step 6: Seek financial support {#step-6-seek-financial-support}

If you are struggling regardless of the outcome on the increase:

  • Universal Credit (housing element) or Housing Benefit: if your income is low enough to qualify, these may cover part of your rent
  • Local Housing Allowance (LHA): the maximum housing support for private renters, set by area; check the LHA rate for your Broad Rental Market Area at gov.uk
  • Discretionary Housing Payment (DHP): if LHA falls short of your rent, your local council may top up via DHP for a limited period
  • Local welfare assistance: many councils have emergency support funds; worth calling your council directly
  • Shelter and Citizens Advice: can advise on eligibility and help with applications

These options usually buy time rather than solve the problem permanently, but that time can matter while you work through the other steps.

If none of these options resolve the problem

If the tribunal sets a market rent you still cannot afford, and financial support does not bridge the gap, the tribunal cannot help further. It sets rent at what the market would bear, not at what you can afford. That is the limit of what the law provides.

At that point, the decision becomes whether to continue in the property or look for somewhere cheaper. That is a significant decision, and worth reaching only after working through the options above, particularly the tribunal route, which many tenants do not pursue because they do not know they can submit first and decide whether to continue.

The most important thing: if you are going to challenge, do it before the proposed effective date on the Form 4A. That deadline cannot be extended once it passes.

For the next practical step, ask us to check the notice with you before the deadline passes.

Frequently asked questions

You can challenge before the proposed start date. If the tribunal decides after that date, any new rent will usually begin on the next payment date after its decision. Simply refusing to pay without applying can create arrears.
A landlord cannot lawfully evict you simply because you challenged a rent increase. Section 21 has ended, but a landlord can still seek possession on statutory grounds.
You can ask the tribunal to postpone the payment date on hardship grounds. Give full details of your finances and explain why paying from the proposed date would cause hardship.
The tribunal sets market rent. It cannot set rent at what you can afford. If the tribunal sets a figure you still cannot afford, your options include negotiating directly with your landlord, seeking housing benefit or Local Housing Allowance (if eligible), or ultimately looking for cheaper accommodation. Working through all the steps before reaching that conclusion matters.
No. You do not need a representative. The application normally costs £47, although some applications are exempt and help with fees may be available.
