How to Prepare Evidence for a Rent Tribunal Hearing

You have decided to challenge your rent increase at the First-tier Tribunal. You have submitted your application, and now comes the part that actually determines the outcome: your evidence. If you have already read our rent increase tribunal guide and understand what happens after you apply, this guide picks up where those leave off. It focuses entirely on building the strongest possible evidence for your case.

You do not need a solicitor or a perfect case. What you do need is clear, well-organised evidence that helps the tribunal understand what your property is genuinely worth on the open market.

What the tribunal is trying to determine

Before gathering evidence, it helps to understand what the tribunal is actually deciding. The First-tier Tribunal (Property Chamber) is not judging whether your landlord is being unfair or whether you can afford the increase. It is answering one specific question: what is the open market rent for this property?

Open market rent means the rent the property would reasonably achieve if it were let on the open market today, on the same terms as your current tenancy, in its current condition. The tribunal ignores any improvements you have made as a tenant, but it does take into account the property's actual state -- including any disrepair, defects, or shortcomings.

This is important because it tells you exactly what kind of evidence matters: evidence about what similar properties rent for, and evidence about the condition of your specific property.

Types of evidence the tribunal considers

1. Comparable rental evidence

This is the most important category. The tribunal wants to see what similar properties in your area are actually renting for. "Similar" means:

• Same type of property (flat, terraced house, semi-detached, etc.)
• Similar size (number of bedrooms, approximate square footage if available)
• Same general area (ideally within half a mile, and certainly the same town or neighbourhood)
• Similar condition and standard of finish

Where to find comparable rents:

• Rightmove, Zoopla, and OpenRent -- search for properties to rent in your area and filter by bedroom count and property type. Screenshot listings, noting the asking rent, location, and features.
• ONS and Valuation Office data -- the Office for National Statistics and the Valuation Office Agency publish rental statistics by local authority area, giving a broader market picture.
• Neighbours and friends -- if you know people renting similar properties nearby, their actual rent (with permission) is strong evidence because it reflects a real agreed figure rather than an asking price.

Aim for three to five good comparables. For each one, note the rent, location, property type and size, and any differences from your property. Be honest -- the tribunal will notice if you cherry-pick only the cheapest listings.

2. Property condition evidence

The condition of your property directly affects what it is worth on the open market. If your home has issues that a typical tenant would consider when choosing whether to rent it, those issues are relevant.

What to document:

• Damp and mould -- photograph any visible damp, mould growth, or condensation. Note which rooms are affected.
• State of repair -- cracked windows, broken fixtures, faulty plumbing, leaking roofs, peeling paint.
• Heating and insulation -- an outdated boiler, single glazing, poor insulation, or draughty windows.
• Kitchen and bathroom -- outdated or worn fixtures bring down the market value.
• EPC rating -- your Energy Performance Certificate is an official measure of efficiency. A poor rating compared to your comparables strengthens your case.

Photographs are powerful evidence -- objective, easy for the tribunal to review, and difficult for the landlord to dispute. Take clear, well-lit photos with dates.

3. Tenancy and notice documents

Include copies of:

• Your current tenancy agreement
• The Section 13 notice you received
• Any previous rent increase notices
• Any correspondence with your landlord about the increase

These help the tribunal understand the terms of your tenancy and confirm the procedural details of the increase.

How to present your evidence

The tribunal is informal compared to a court, but clear presentation still matters. A well-organised bundle of evidence is easier for the panel to follow, and it shows you have taken the process seriously.

Organise by category. Group your evidence into sections: tenancy documents, comparable rental evidence, and property condition evidence.

Write a brief summary. Include a one-page front sheet explaining what rent you currently pay, what your landlord has proposed, what rent you believe is fair, and why -- referencing the evidence you have included.

Label everything. Number your documents and refer to them by number in your summary. Label photographs clearly (for example, "Photo 1 -- damp in bedroom, north wall, taken 15 March 2026").

Keep it concise. A focused bundle of 15 to 20 pages is more effective than 50 pages of loosely relevant material.

Common mistakes to avoid

Using comparables that are not genuinely similar. A three-bedroom house is not comparable to a one-bedroom flat. A property in a premium postcode is not comparable to one on a busy main road. Choose comparables carefully and acknowledge differences honestly.

Focusing on personal circumstances. The tribunal sets a market rent, not a rent you can afford. Focus your evidence on market data and property condition, not your financial situation.

Submitting evidence late. The tribunal sets a deadline for evidence, and late submissions may not be accepted. Mark the deadline in your calendar and aim to submit at least a few days early.

Ignoring the landlord's evidence. Your landlord may also submit comparable evidence showing higher rents. If you can, review their comparables and note any reasons they are not genuinely comparable to your property (different area, better condition, larger size, etc.).

Not including photographs. Words describe problems; photographs prove them. If your property has condition issues, photograph them. It takes minutes and can make a significant difference.

Timeline for evidence preparation

Once your application is acknowledged by the tribunal, you will typically receive a timetable that includes:

• Evidence submission deadline -- usually two to four weeks before the determination date. Both you and your landlord are expected to submit evidence by this date.
• Paper determination or hearing date -- the date the tribunal will consider the case. Many rent increase cases are decided on paper, without a hearing.
• Decision -- usually issued within a few weeks of the hearing or paper determination.

Start gathering your evidence as soon as you submit your application. Do not wait for the tribunal to set a deadline -- comparable listings can disappear from property websites, and property condition can change.

What happens at the hearing itself

If the tribunal schedules a hearing rather than a paper determination, it is typically informal and lasts 30 to 60 minutes. You may attend in person, by phone, or by video. The panel will ask both sides to summarise their evidence, ask questions, and may discuss specific comparable properties. You do not need to be an expert speaker -- be honest, be clear, and refer to your evidence. The panel may also arrange a property inspection if condition is a key issue.

Pulling it all together

Building evidence for a tribunal case is not about being a legal expert. It is about showing the tribunal what your property is actually worth, supported by facts. Find comparable properties, document your property's condition, organise everything clearly, and submit it on time.
