The tribunal set my rent between what I pay now and what my landlord asked: did I still win?

You challenged your rent increase, the decision has arrived, and the number is a bit confusing. It is lower than the figure your landlord wanted, but higher than the rent you were paying. So did you win, or did you just talk the tribunal into a slightly smaller rise?

You won. Or at least, you saved money, which is what winning a rent challenge actually looks like most of the time. The idea that a successful challenge freezes your rent is one of the biggest misunderstandings about the process. Here is what a "partial win" really means, how to work out what you saved, and why it is almost always worth it.

What the tribunal is deciding

When you refer a Section 13 increase to the First-tier Tribunal, it does not decide whether the increase is fair to you personally, or whether you can afford it. It decides one thing: the open market rent for your property, under section 14 of the Housing Act 1988. In other words, what your home would let for today on the open market.

That figure lands somewhere on a line. At one end is the rent you pay now. At the other is the rent your landlord proposed. The determination can sit anywhere along it.

So there are really three possible outcomes.

• Below your current rent. Uncommon, but it happens where there is serious disrepair, or the landlord's figure was wildly out of step with the market. Your rent goes down.
• Between current and proposed. The most common outcome when a challenge succeeds. The tribunal agrees the landlord asked for too much, but finds the true market rent is somewhere above what you were paying. This is the partial win.
• The proposed figure confirmed. The tribunal decides the landlord's number was fair after all. No change from the notice.

A partial win is the middle outcome, and it is a good one.

The maths of a partial win

The easiest way to see the value is to run the numbers.

Say you were paying 1,000 pounds a month. Your landlord proposed 1,250. You challenged, and the tribunal set the market rent at 1,100.

Your rent still went up, from 1,000 to 1,100. But against what your landlord wanted, you are 150 pounds a month better off. Over a year that is 1,800 pounds you are not paying. That is the real figure to look at, because 1,250 was the alternative if you had done nothing.

And it does not stop after one year, because of how the baseline works.

Why the saving compounds

The rent the tribunal sets becomes your new baseline. Two things follow from that.

First, your landlord cannot increase the rent again for at least 52 weeks. You get a full year of stability at the determined figure.

Second, when the next increase does come, it builds on the lower number the tribunal set, not the higher one your landlord originally wanted. In the example above, next year's increase starts from 1,100, not 1,250. So the gap you won this year keeps paying off in every year that follows. A partial win is not a one-year delay. It is a permanent reset of the figure your rent grows from.

The rule that removes the risk

There used to be a real reason to hesitate before challenging. The tribunal could set the rent higher than the landlord had asked for, so a challenge could, in theory, backfire.

That rule is gone. Since 1 May 2026, the tribunal cannot set your rent above the figure your landlord proposed. The proposed rent is now the ceiling, which means it is your worst case. You cannot come out of a challenge paying more than the notice already said.

That changes the whole decision. If the worst that can happen is the figure you were already being asked to pay, then any reduction the tribunal makes is pure upside. A likely partial win is money saved with no downside on the decision itself.

When a partial win is the realistic outcome

It helps to go in with honest expectations. A partial win is most likely when the landlord has overshot the market but the market has genuinely moved. If your rent has been frozen for a few years while local rents climbed, some increase may well be fair, and the tribunal will reflect that. What it will not do is rubber-stamp a figure that sits above what comparable homes actually rent for.

So the goal of a challenge is usually not to freeze the rent. It is to get the tribunal to set the true market figure and strip out the overreach. When that figure sits between your current and proposed rent, the system has done exactly what it is meant to do.

We never promise a particular outcome, because every property and local market is different. But understanding that a partial reduction is both common and valuable takes a lot of the fear out of the decision.

What to do next

If you are deciding whether to challenge in the first place, the question is not whether you will get a total freeze. It is whether the proposed rent looks above the market. If it does, a challenge is likely to claw some of that back, and the proposed figure is the most you can end up paying.

Keep paying the correct rent while any case runs, so no arrears build up. And before you pay the tribunal fee, which is 47 pounds from 1 May 2026, run a free grounds check. It compares the proposed rent against the local market and tells you whether there is a case worth making, so you go in with the numbers in front of you rather than a hunch.

A smaller increase than your landlord wanted is not a consolation prize. It is the win, and it keeps paying you back every year after.
