After your rent tribunal decision: what happens next for tenants in England

Your First-tier Tribunal hearing is done. The decision letter will land 2 to 4 weeks later. This post walks through exactly what happens next — what the decision says, when the new rent (if any) starts, what you owe, what recourse exists, and what this means for your next rent increase down the line.

This guidance is for England only. It covers both the old rules that apply for decisions on notices served before 1 May 2026 and the new rules under the Renters' Rights Act 2025 that apply to notices served from 1 May 2026 onwards. The two sets of rules differ in ways that matter, so we'll flag both.

When the decision arrives

Most First-tier Tribunal (Property Chamber) decisions on Section 13 rent references come out within 2 to 4 weeks of the hearing. You'll usually receive:

• A decision letter signed by the tribunal panel.
• A short reasons document explaining how the tribunal reached the figure.
• A copy of the determination, which is the legally binding bit.

Your landlord gets the same paperwork. Neither of you should be hearing about the outcome via anyone else.

How to read the decision

Look for four pieces of information in the determination:

1. The rent the tribunal has set. Usually a single monthly or weekly figure. This might be the same as your landlord proposed, lower, or — for notices served before 1 May 2026 — occasionally higher.
2. The effective date — when the new rent applies from.
3. The period of the tenancy it applies to (weekly, monthly, etc.).
4. Any directions — occasionally the tribunal directs the landlord to do something specific (for example, confirm the new rent in writing).

Then read the reasons. They're often the most useful part of the whole process: the tribunal spells out how it weighed the market evidence, disrepair, property condition, and anything else that influenced the figure. If you ever face another rent increase from the same landlord, the reasons are gold dust.

The decision is binding — for both sides

A First-tier Tribunal decision is binding. Your landlord can't simply ignore it and ask for a different figure. You can't ignore it either — once the effective date arrives, the rent the tribunal has set is the lawful rent under your tenancy.

That applies whether the figure went up, down, or stayed the same.

When the new rent takes effect

This is where the old rules and the new rules differ. Read the section that matches your notice date.

If your notice was served before 1 May 2026 (old rules)

The new rent applies from the effective date on the original Section 13 notice (Form 4) — not the date of the tribunal decision.

That means:

• If you won (rent reduced), you pay the lower figure from the notice's effective date.
• If you lost (rent kept or raised), you pay the higher figure from the notice's effective date — backdated. If the tribunal hearing happened months after the effective date, you could owe several months of back-rent.
• If the tribunal kept the figure the same as the landlord's proposed rent, you pay that from the effective date.

The backdating is one of the main reasons tenants under the old rules avoided challenging unless they were confident about their grounds.

If your notice was served from 1 May 2026 onwards (Renters' Rights Act 2025 rules)

The new rent applies from the date the tribunal's decision takes effect — usually the decision date itself or a date specified in the determination.

That means:

• No backdating. If the tribunal takes 10 weeks to decide, you don't owe 10 weeks of higher rent.
• Even better for tenants: the tribunal cannot set the rent higher than the landlord proposed. The worst case is that the landlord's figure is confirmed from the decision date.
• If the tribunal reduces the rent, the reduced figure applies from the decision date.

The new rules are substantially safer for tenants. They're also the reason the number of rent challenges is expected to rise sharply from May 2026 onwards.

What you pay in the short term

Until the decision takes effect, keep paying the old rent. Don't withhold rent, don't pay a "best guess" figure, don't pay the new rent early to avoid an awkward conversation. Non-payment creates rent arrears, which opens the door to separate eviction proceedings under Section 8 — a risk with consequences much worse than the rent increase itself.

Once the decision arrives:

• If the new figure is higher than what you've been paying and the notice was served before 1 May 2026, you'll owe back-rent from the effective date to today. Ask the landlord for a payment plan if the sum is substantial. Most landlords will accept.
• If the new figure is lower than what you've been paying (which only happens if you'd already been paying the notice's proposed rent for some reason), you're owed a refund from the effective date to today.
• If the new figure is higher and the notice was served from 1 May 2026 onwards, you pay the new rent from the decision date — no back-rent to worry about.

Appealing the decision

Either side can ask for permission to appeal to the Upper Tribunal (Lands Chamber). The grounds are narrow and the deadline is tight.

• Who can appeal: either party.
• Grounds: error of law (the tribunal misapplied the legal rules) or serious procedural unfairness. Dissatisfaction with the figure is not a ground.
• Deadline: 28 days from the date on the decision letter.
• Process: apply in writing to the First-tier Tribunal for permission. If refused, you can then apply to the Upper Tribunal directly. If permission is granted, the Upper Tribunal hears the appeal.

Realistically, successful tenant appeals are rare. The First-tier Tribunal is a specialist panel (usually a legally-qualified judge and a surveyor or valuer), and their factual findings are hard to overturn. Appeal only if you have a genuine legal or procedural issue — never on the basis of "I think the figure is too high."

Seek advice from Citizens Advice, Shelter, or a solicitor specialising in housing law before filing. Most appeals are better spent as a stronger challenge at the next rent increase.

Future rent increases from the same landlord

After the dust settles, two things hold true for 52 weeks:

1. Your landlord cannot serve another Section 13 notice for at least 52 weeks from the effective date of the rent set by the tribunal.
2. If they try, the new notice is invalid — the 52-week rule doesn't care about the tribunal history; it's a statutory minimum gap.

Use the 52-week window to:

• Save the decision paperwork carefully — you may need it later.
• Keep a running log of any repair issues, since disrepair is a relevant factor in future rent challenges.
• Check local comparable rents every 6 months so you know what "market rate" looks like in your area.

When the next rent increase lands, you'll be a much better-informed tenant — and from 1 May 2026 onwards, you'll be challenging under a set of rules that favour you.

What if the landlord retaliates?

Legally, retaliatory eviction against a tenant who exercised their right to challenge a rent increase is tightly restricted under the Deregulation Act 2015 (pre-1 May 2026) and further restricted under the Renters' Rights Act 2025 (from 1 May 2026 onwards).

In practice:

• If the landlord serves a Section 21 notice within six months of your challenge, you can ask a court to set it aside as retaliatory (pre-1 May 2026).
• From 1 May 2026, Section 21 no-fault evictions are abolished entirely. The only eviction routes are fault-based (Section 8).
• If you receive any eviction notice after challenging a rent increase, seek advice immediately from Citizens Advice or Shelter.

What RentSOS does after a decision

If you used RentSOS for the original challenge, the £14.99 pack included the tribunal application template. After the decision, we can:

• Help you read the reasons document to understand what mattered to the tribunal.
• Flag if your landlord attempts to serve another Section 13 notice within the 52-week window.
• Generate a fresh check next time a notice arrives, using the rent figure the tribunal set as the new baseline.

You don't pay again for this unless a new notice arrives and grounds are found to challenge it.

If you're unhappy with the process but not the outcome

The tribunal will sometimes reach a decision you disagree with for reasons that aren't legal grounds for appeal. If the process itself was poor — a biased panel member, documents you submitted being lost, a procedurally irregular hearing — you can complain separately to HMCTS (HM Courts and Tribunals Service). That's not the same as an appeal and won't change the outcome, but it's the right route for process issues.

FAQs

Q: How long after the hearing will the decision arrive? A: Usually 2 to 4 weeks. Occasionally up to 8 weeks if the panel needs more time or issues written directions first.

Q: Can the tribunal set my rent higher than the landlord proposed? A: For notices served before 1 May 2026, yes — this is the main risk under the old rules. For notices served from 1 May 2026 onwards, no — the Renters' Rights Act 2025 removes this risk.

Q: I lost. Do I owe back-rent? A: If your notice was served before 1 May 2026, yes — back to the effective date on the notice. Ask the landlord for a payment plan. If the notice was served from 1 May 2026 onwards, no back-rent — the new figure only applies from the decision date.

Q: My landlord says they're appealing. What happens in the meantime? A: The tribunal's decision takes effect unless the Upper Tribunal orders a stay (rare). Carry on paying the rent the tribunal set. If the appeal succeeds, any overpayments or underpayments will be resolved at that stage.

Q: I'm thinking of moving out. Does the decision still matter? A: Yes — the rent you pay until you leave is the rent the tribunal set. If you gave notice to leave before the effective date, you may be able to leave paying the old rent, depending on the dates. Check the notice period your tenancy requires.

Key takeaways

• The tribunal's decision is binding on both you and the landlord and arrives within 2-4 weeks of the hearing.
• For notices served before 1 May 2026, the new rent is backdated to the notice's effective date, which can mean owing back-rent if you lost.
• For notices served from 1 May 2026, the new rent takes effect from the decision date, with no backdating and no risk of a higher figure.
• You have 28 days to request permission to appeal, but successful appeals are rare and require an error of law.
• Your landlord cannot serve another Section 13 notice for at least 52 weeks from the new rent's effective date.
