I Can't Afford My Rent Increase. What Are My Options?

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

Use the notice validity checker to work through these 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

Filter for “Let Agreed” properties where possible. These reflect actual market transactions, not asking prices.

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, file a Rents 1 application to the First-tier Tribunal (Property Chamber) before the effective date. This means:

• Free to submit so you can preserve the deadline, with a £47 government processing payment if you continue
• Safe: Section 21 is abolished; your landlord cannot evict you for challenging
• Protected on payment: you continue paying your current (old) rent while the case is heard, with no backdated arrears risk

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

You continue paying your current rent. The proposed new rent does not take effect while the application is pending. Once the tribunal decides, the new rent applies going forward. Cases can take months, which gives you time to negotiate, gather evidence, or plan around the outcome.

Step 4: Request a hardship deferral

If the tribunal determines a new rent and you need more time before it takes effect, you can ask for a hardship deferral. The tribunal can delay the new rent’s effective date by up to 2 months after determination if immediate application would cause undue hardship.

Request this on the Rents 1 application itself, with supporting financial details. This is not granted automatically. You need to make the case. But it exists precisely for situations where a sudden step up in rent would cause serious difficulty.

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 negotiate a lower figure, both parties sign a withdrawal and the agreed rent takes effect. The tribunal application lapses with no penalty.

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.

Quick reference

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, check whether the notice is valid or generate a Rents 1 application before the deadline passes.
