Understanding the Market Rent Comparison in Your Rent Challenge
Learn how market rent comparisons work when challenging a rent increase, how to find comparable properties, and what the tribunal considers.
Frequently Asked Questions
+Can the tribunal set a rent higher than my landlord proposed?
No. The First-tier Tribunal cannot set a rent higher than the amount on your landlord's Section 13 notice. This means there is no risk of ending up worse off by challenging.
+What if my landlord has better comparable evidence than me?
The tribunal considers all evidence from both sides. Even if your landlord submits strong comparables, the tribunal will also weigh your evidence and make their own assessment. Having some evidence is always better than having none.
+How many comparable properties do I need?
There is no minimum, but 3-5 strong comparables is a good target. Quality matters more than quantity. One excellent comparable in the same building is worth more than ten vague ones from across town.
+Should I include properties that support a higher rent?
Yes. If there are comparable properties at or above your landlord's proposed rent, acknowledging them and explaining why they are not directly comparable (different condition, larger, better location) shows the tribunal you have done thorough research.
+What if I cannot find any comparable properties?
In unusual situations -- very rural areas, unique property types -- the tribunal may consider a wider geographical area or adjust more heavily for differences. Speak to local letting agents for their professional view, and explain the difficulty in your tribunal submission.

Is my landlord raising the rent just to force me out? What the law actually allows
A large rent increase can feel like a quiet eviction, especially now that no-fault eviction is gone. But a Section 13 must reflect genuine market rent, not what would make you leave. Here is where you stand.
The tribunal set my rent between what I pay now and what my landlord asked: did I still win?
Winning a rent challenge rarely means the rent stays frozen. It usually means the tribunal sets a fair figure below what your landlord asked. Here is how to work out what you actually saved.
Your landlord did up the flat and now wants a big rent rise: can you still challenge it?
A new kitchen or bathroom lets a landlord ask for more, but not for any figure they like. Here is how to tell a fair improved-market rent from an overreach, and when you can still challenge.
If I challenge my rent increase, will my landlord just try again next year?
Worried that challenging your rent increase just delays the next one? Here is what stops your landlord raising the rent again, why a successful challenge lowers your baseline for good, and why challenging is still worth it.
Is it worth challenging my rent increase? Your real chances at the tribunal
Before you spend the fee and the hours preparing an evidence bundle, there is a fair question worth answering honestly: is challenging your rent increase actually worth it? What are your real chances of the tribunal reducing the rent, and how do you know before you apply whether you have a genuine case or are about to pay to confirm the very increase you were fighting? The honest answer is that it is not a coin toss and it is not a lottery. Whether a challenge is worth it comes down to two things you can check in advance: whether the notice is procedurally valid, and whether the proposed rent is above the real market rent. Get those two answers and you already know most of what you need. This walkthrough gives you a straight, no-hype view of when a challenge is worth running, when it is not, and how the rules that changed on 1 May 2026 shifted the odds in tenants' favour.

The rent increase is huge but still under market: can I challenge it?
It is the question that catches more tenants out than almost any other. Your rent is jumping by hundreds of pounds, a 20%, 30%, even 40% increase in one go, and it feels obviously unfair. Surely an increase that big is something you can challenge? The hard truth is that the First-tier Tribunal does not judge the size of the increase at all. It judges one thing: what the property would let for on the open market today. If the new rent is at or below that market figure, a big jump on its own is not grounds to win, even though it feels like it should be. This walkthrough explains why the size of the increase is the wrong thing to focus on, what actually decides a tribunal case, and how to work out before you apply whether you have a real chance or are about to pay 47 pounds to lose.
