How long does a rent increase tribunal take in England?

There is no guaranteed timetable. It depends on the tribunal's workload, whether more evidence is needed and whether the case can be decided on the papers or needs an inspection or hearing.

What evidence does the tribunal use to determine rent?

The tribunal considers the property's condition and comparable local lettings. Listings can help, but they usually show asking prices; evidence of actual agreed rents is stronger. The tribunal's membership varies by case.

Can the tribunal set rent higher than my landlord proposed?

No. Under the Renters' Rights Act 2025, the First-tier Tribunal cannot set rent above the figure the landlord proposed in the Form 4A notice. The worst outcome is that the tribunal confirms the proposed figure.

Can I appeal a First-tier Tribunal rent decision?

A decision may be appealable to the Upper Tribunal, normally on a point of law and with permission. Follow the appeal and reasons deadlines stated in the decision and tribunal rules rather than relying on a general deadline.

Challenging a Rent Increase at Tribunal: How It Works

If your landlord has served a Form 4A rent increase notice and you want to challenge the proposed rent, this is the tribunal process from application to decision.

How to apply

Apply for an open market rent determination through the online service or on paper using form MR1. The application normally costs £47, although some applications are exempt and help with fees may be available. Ask us for free help if you want to challenge. You must apply before the effective date stated in your rent increase notice. After that date passes without a challenge, the new rent normally takes effect.

Note on form names: Older content may call the paper form “Rents 1”. Current HMCTS guidance calls the process an open market rent determination and provides paper form MR1.

If you want only a ruling on whether the notice is valid, use the paper MR1 route and make that clear. If the tribunal finds the notice valid, you must make a separate application if you also want the amount assessed. See our guide on invalid rent increase notices.

You can’t be evicted for applying

Section 21 no-fault evictions are abolished under the Renters’ Rights Act 2025. Engaging with the tribunal — whether you’re a tenant applying or a landlord responding — does not put the tenancy at risk.

What “open market rent” means

The tribunal doesn’t rule on whether your landlord’s proposed figure is fair in any abstract sense. It determines what the property would reasonably let for on the open market: what a new tenant would pay, under equivalent terms, if the property were advertised today. That is the legal standard under Section 14 of the Housing Act 1988.

What the tribunal ignores

When setting market rent, the tribunal must disregard:

Any discount for being a sitting tenant
Improvements you funded yourself (new kitchen, flooring, boiler, etc.)
Any reduction in value caused by your own breach of the tenancy

If you improved the property at your own expense, the tribunal sets rent as if those improvements were not there.

Evidence

You do not need to hire an expert. Submit comparable lettings: similar properties nearby that have recently let, ideally within the last 12 months. Listings can help, but actual agreed rents are stronger evidence. Follow the tribunal’s directions for evidence deadlines; late material may receive less weight or be excluded.

For step-by-step guidance on finding, selecting, and presenting comparables, see our evidence guide.

Paper vs oral hearing

Many rent cases are decided on the papers without a hearing. If the property’s condition or what’s provided is genuinely disputed between the parties, request an oral hearing. The Upper Tribunal has overturned multiple paper decisions where contested facts were not properly tested.

What a hearing looks like

The hearing is less formal than a court. A tribunal is usually made up of 2 or 3 members; the chair is usually a lawyer or surveyor and the other members’ backgrounds can vary. The panel asks questions of both sides. Legal representation is not required. The notice will tell you whether the hearing is in person, by video or by telephone.

Timeline

There is no guaranteed timetable. How long the case takes depends on:

whether the application and attachments are complete;
whether the landlord responds;
whether the tribunal needs more evidence; and
whether the case can be decided from the documents or needs an inspection or hearing.

The tribunal will tell the parties what happens next. If you believe an inspection or hearing is needed for a fair decision, explain why in the application.

What to pay while you wait: Continue paying your old rent. Under the Renters’ Rights Act 2025, the proposed new rent does not take effect while your application is pending. Once the tribunal decides, the new rent applies going forward.

For the payment-date rules and possible hardship protection, see what to pay while waiting for the tribunal.

The outcome

The tribunal determines the open-market rent and states when it starts. If its decision comes after the proposed start date, any new rent will usually begin on the next payment date after the decision rather than being charged for the intervening months.

After the decision

The decision or accompanying tribunal guidance will explain how to ask for reasons, seek permission to appeal or request a correction. Follow the specific deadlines given there; do not wait for a general guide.

Before applying, make sure you have checked the notice itself and gathered comparable-rent evidence. Those two points usually decide whether a challenge is worth pursuing.
