Can I Refuse a Rent Increase? Your Rights as a UK Renter

If you've just opened a letter telling you your rent is going up, it's completely understandable to feel a knot in your stomach. That letter is known as a Section 13 notice, and receiving one can feel overwhelming — especially if the increase is more than you can easily absorb.

Here's what you need to know straight away: you have rights. You don't have to simply accept the new figure. There are proper, legal steps you can take — and this guide will walk you through all of them.

The short answer

You can't simply "refuse" a valid Section 13 notice in the way you might refuse an invitation. Ignoring it won't make it go away, and it won't stop the increase from taking effect.

But — and this matters — you absolutely can challenge it. Formally. Through the First-Tier Tribunal. That's not fighting your landlord; it's using a legal process that exists precisely for situations like yours.

There's an important distinction here:

• Ignoring the notice = the increase takes effect automatically on the proposed date. You're now legally obliged to pay the higher rent.
• Challenging the notice = you refer it to an independent tribunal before the effective date. A neutral panel reviews whether the proposed rent is fair for your area.

One of those options keeps you in control. The other doesn't.

What "refusing" actually means in practice

If you receive a Section 13 notice and take no action before the date stated on it, the new rent amount becomes legally binding — whether or not you think it's fair. Your landlord doesn't need to do anything else. The increase simply takes effect.

This catches a lot of renters off guard. They assume that if they don't sign anything or don't respond, nothing changes. Unfortunately, that's not how it works.

So "refusing" in the everyday sense — deciding you won't pay — isn't a safe option. It could put you in rent arrears, which has serious consequences for your tenancy.

What you can do is use the formal process. That's what we're here to help with.

Your three options

Once you receive a Section 13 notice, you have three choices:

a) Accept the increase If you've checked the local market and the new rent seems reasonable, accepting may be the simplest path. You don't need to do anything — the increase takes effect on the date in the notice.

b) Negotiate directly with your landlord Before going to tribunal, it's worth having a conversation. Many landlords — particularly those who made procedural errors on the notice — are open to agreeing a different figure rather than going through a formal process. A polite, factual approach often works better than people expect. Keep any agreement in writing.

c) Challenge at the First-Tier Tribunal If you believe the proposed rent is above market rate, or if the notice contains errors, you can refer it to the tribunal before the effective date. The process is free, you don't need a solicitor, and a panel of independent experts will set a fair market rent for your property. Read our full guide to how to challenge a Section 13 rent increase.

When you have the strongest grounds

Not every challenge will succeed, but some situations give you particularly solid grounds:

• Procedural errors in the notice — the wrong form was used, required information is missing, or the notice period wasn't given correctly. Many of these errors are genuine mistakes, but they still make the notice invalid.
• The 52-week rule wasn't respected — your landlord can only raise your rent once every 52 weeks. If it's been less than that since your last increase, the notice may not be valid.
• The proposed rent is above market rate — if similar properties nearby rent for noticeably less, that's meaningful evidence for the tribunal. Comparable listings, local rental data, and letting agent reports can all support your position.
• Wrong form used — Section 13 increases must use the prescribed Form 4. Using a different form or a landlord-created letter doesn't meet the legal requirement.

We built RentSOS to check all of these automatically. Run your free check now to see whether your notice has any of these issues.

When challenging may not help

It's important to be honest here. If your notice was served correctly, the form is right, the timing is valid, and the proposed rent is broadly in line with what similar properties charge locally — the tribunal is likely to confirm a rent close to what your landlord proposed.

Challenging in that situation won't necessarily reduce the increase, and it will delay it by a few months while the process runs. That may still be worth doing for breathing room, but go in with realistic expectations.

This is why checking your notice first makes sense. It takes two minutes and tells you whether you have genuine grounds before you decide.

The Renters' Rights Act change — what it means for you

From 1 May 2026, an important change comes into effect under the Renters' Rights Act.

Currently, there's a risk that if you challenge a rent increase at tribunal, the panel could set the rent higher than your landlord originally proposed. That risk has put some renters off challenging, even when they had good grounds.

From 1 May 2026, that risk is removed. The tribunal will only be able to set rent at or below what the landlord proposed. In other words, challenging becomes a safer option — the worst outcome is that you end up paying what was originally asked.

If you've been hesitating because of this risk, that hesitation may no longer apply once the change takes effect.

Frequently asked questions

Can I simply refuse to pay a rent increase?

Not safely, no. If you receive a valid Section 13 notice and don't challenge it before the effective date, the new rent becomes legally binding. Refusing to pay it could put you in arrears, which puts your tenancy at risk. The right move is to challenge through the tribunal — not to stop paying.

What happens if I ignore a Section 13 notice?

The increase takes effect automatically on the date stated in the notice. You'll be legally obliged to pay the higher amount from that point. Ignoring the notice doesn't give you any protection — it just removes your chance to challenge.

Can I negotiate with my landlord instead of going to tribunal?

Yes, and it's often worth trying first. If you can reach a mutually agreed figure, that avoids the tribunal process entirely. Put any agreement in writing and make sure both parties are clear on the new amount and the date it applies from. Some landlords prefer this, particularly if there are procedural issues with the notice they'd rather not have scrutinised.

How do I know if my rent increase is too high?

The benchmark is the open market rent for similar properties in your area. Look at comparable listings on Rightmove, Zoopla, or local letting agents — properties with a similar number of bedrooms, in a similar location, with similar features. If the proposed rent is noticeably above what those properties are asking, that's a reasonable basis for a challenge. RentSOS can help you assess this as part of your free notice check.

Is challenging a rent increase worth it?

It depends on your specific situation. If your notice has procedural errors, or the proposed rent is above market rate, then yes — challenging at tribunal is free, takes no specialist knowledge, and could result in a lower rent being set. From 1 May 2026, the tribunal also cannot set rent higher than what your landlord proposed, which removes one of the main risks of challenging. If the notice is valid and the rent is fair, the outcome is less certain — but it may still buy you time.

Will my landlord evict me if I challenge the rent increase?

This is one of the most common fears renters have, and it's worth addressing directly. Using the tribunal process is a legal right. A landlord cannot lawfully evict you simply because you referred a Section 13 notice to tribunal. Under the Renters' Rights Act, retaliatory eviction protections have also been strengthened. Exercising your legal rights is not grounds for eviction.
