You've paid rent every month to a landlord who was breaking the law. Maybe they never licensed the HMO. Maybe they ignored an improvement notice from the council. Either way, you may be able to claim back rent you paid while the offence was happening, and the First-tier Tribunal (Property Chamber) in England is the place to do it. The question most tenants get stuck on is what to put in the bundle.
A rent repayment order (RRO) is not won on good intentions. The tribunal applies the criminal standard of proof, meaning beyond reasonable doubt. That sounds daunting, but most landlord offences leave a paper trail. Your job is to collect that trail, organise it clearly, and submit it in a format the tribunal can follow.
If your landlord rents out an unlicensed HMO, or has ignored an improvement notice, or has been illegally evicting tenants, you already have a strong foundation. Rent repayment orders cover a defined list of offences, from unlicensed HMOs to illegal eviction and failure to comply with a prohibition order, set out in the Housing and Planning Act 2016 and GOV.UK's rent repayment order guidance for tenants. The maximum is up to 12 months' rent for offences before 1 May 2026 and up to 2 years for offences from that date. If a licensing or notice offence started before 1 May 2026 and is still going, regulation 11 of SI 2026/421 keeps the old 12-month rules for the pre-May part, and the part from 1 May counts under the new 2-year limit, so it cannot reach a full 2 years until May 2028. Do not add the two caps together. On a £1,200 per month tenancy, 6 eligible months gives a ceiling of £7,200. It is worth getting the evidence right.
What offences qualify for a rent repayment order in England?
Before you build your evidence bundle, you need to confirm the landlord has committed one of the qualifying offences. The tribunal cannot award a rent repayment order for general bad behaviour or even serious disrepair on its own.
The offences that qualify under the Housing and Planning Act 2016, and extended by the Renters' Rights Act 2025, include:
- Letting an HMO that needs a licence without one (section 72(1) of the Housing Act 2004)
- Letting a house that needs a selective licence without one (section 95(1) of the Housing Act 2004)
- Failing to comply with an improvement notice or prohibition order
- Illegal eviction or harassment of tenants under the Protection from Eviction Act 1977
- Failure to comply with a banning order
- Using violence to secure entry under section 6 of the Criminal Law Act 1977
- Knowingly or recklessly misusing a possession ground, re-letting or marketing during the restricted period after a moving-in or selling ground, and continuing a tenancy-reform breach after a civil penalty (section 16J of the Housing Act 1988, for offences from 1 May 2026)
The time limit depends on when the offence was committed, not on which offence it was. For offences committed on or after 1 May 2026, the Renters' Rights Act 2025 extended the application window to two years. For offences before that date it remains 12 months from the date of the offence. Miss it and the tribunal will reject the application, whatever the evidence. This route covers housing in England. Wales has its own separate scheme.

What documents does a rent repayment order application need?
The RRO1 form is where you start, but the form is only the container. What goes inside is what matters.
Every rent repayment order application in England should include the following core documents:
1. Tenancy agreement Include the signed agreement covering the period you are claiming for. If you rented month-to-month for two years but the original fixed term was one year, include both the original agreement and any renewal or correspondence confirming the continuation. The tribunal needs to establish your legal right to occupy during the claim period.
2. Proof of rent payments Bank statements are the cleanest evidence here. Export statements showing every payment leaving your account to the landlord or their agent, clearly labelled with the reference and amount. If you paid cash, you need receipts or a rent book. The tribunal will not award repayment for months you cannot prove you paid. Take off any rent covered by Universal Credit or Housing Benefit, because only rent paid by you, or by someone else on your behalf other than through benefits, counts. Go through every statement and highlight each relevant payment before including it.
3. Evidence of occupancy This is sometimes overlooked. The tribunal needs to know you were living at the property during the period covered. Utility bills, council tax correspondence, GP or dentist registration records, or addressed post all work. The point is to show continuous occupation, month by month if possible.
4. Evidence of the offence This is the section that determines whether you win or lose. How you prove the offence depends on what the offence is.
How to prove your landlord committed the specific offence
The evidence you need for the offence itself varies depending on which category applies.
Unlicensed HMO Contact your local council and ask whether the property holds a valid HMO licence. You can do this by email and the reply becomes your evidence. Many councils also publish public registers online. A screenshot with a timestamp of the council's licence register showing no entry for your address is usable evidence. Ask the council to confirm in writing whether a licence application or temporary exemption notice was received, and on what date, because a valid pending application is a defence. You also need to show the property was an HMO that needed a licence for the whole claim period: who lived there, how many households, and which kitchen or bathroom you shared. If the council has already taken action, any enforcement notices they issued are valuable, so include them in full.
Failure to comply with an improvement notice or prohibition order Request a copy of any notice or order served on the property from your local authority's environmental health team. For an improvement notice, you need the notice with its start and completion dates, proof it became operative (no appeal, or the appeal outcome), and proof the works were not started or finished on time, such as a council re-inspection, dated photos or correspondence. The hazard must be in your home, not the common parts. For a prohibition order, evidence that the landlord kept letting or using the premises in breach of it closes the loop.
Illegal eviction This is harder to document but not impossible. Photographs of locks changed, written communications from the landlord telling you to leave without a valid notice, witness statements from neighbours, and any police reports or council records all count. A clear timeline of events is especially important here. Write it out chronologically, attach the supporting document for each entry, and submit both together.
Selective licensing breach As with HMO licensing, check the council's public register, get a written confirmation from the council that no licence was held, and pair it with your rent payment records for the same period. If you live in Hackney, Westminster, or Islington, all of which have recently updated selective licensing schemes, check the specific local authority rules. Our guides on Hackney selective licensing 2026, Westminster selective licensing 2026, and Islington selective licensing 2026 set out what applies in each area.
What supporting evidence strengthens a rent repayment order claim?
Core documents establish the baseline. Supporting evidence is what takes a claim from plausible to persuasive.
Correspondence with the landlord Print or export every relevant email, text, and WhatsApp message between you and your landlord. This includes anything touching on the licence, the conditions of the property, or any complaints you raised. Even messages where the landlord ignores you or denies there is a problem are useful, because they show awareness.
Photographs and video If the offence involves unsafe conditions or illegal access, dated photographs matter. Most smartphones automatically embed a timestamp in file metadata. Submit photos in their original format, or export them with visible dates.
Witness statements If another tenant in the property or a neighbour witnessed something relevant, a short written statement signed and dated by them is admissible. Keep it factual. Stick to what they saw or heard directly.
A clear timeline This is one of the most useful things you can prepare and one of the least often submitted. Write a two-column document with the date on the left, what happened on the right. Reference each item in your evidence bundle by number or letter. The tribunal judge reads dozens of cases. A readable timeline saves time and signals that you know your case.
Any council or authority communications Housing officer visit reports, email confirmations from environmental health, licensing team decisions, and local authority enforcement records all carry weight because they come from a third party. If the council has already reached a view, include it.
The landlord's enforcement history Ask the council whether the landlord has been convicted or fined by civil penalty for this offence, or has had a conviction, civil penalty or RRO for the same kind of offence before. For offences from 1 May 2026, this can require the tribunal to award the maximum under section 46, unless exceptional circumstances apply.
Put everything in a single PDF bundle with an index at the front and page numbers throughout, following any tribunal directions. GOV.UK's tenant guidance asks for one document. Number each page sequentially so you can refer to specific pages in your statement.
What a rent repayment order statement of case should cover
The RRO1 form asks for a statement of your case. Keep it to a concise explanation of the facts the tribunal needs to know, and leave the frustration out.
Your statement should cover:
- The address and nature of the tenancy
- The dates of your tenancy and the period you are claiming for
- The specific offence you are alleging and the legal basis for it
- A summary of how the evidence proves each element of the offence
- The amount of rent you paid during the relevant period, less any Universal Credit or Housing Benefit, and your calculation of the maximum claim
Keep it under three pages if possible. Use numbered paragraphs. Reference your evidence bundle by document number when making a specific factual point.
You do not need to use legal language. Plain English is fine and often clearer. State what happened, when it happened, and what proves it.
For a step-by-step walkthrough of filling in the form itself, see our RRO1 form step-by-step guide. And if you are wondering how the full tribunal process works from application to decision, how to win a rent repayment order at tribunal goes through each stage in detail.
Common mistakes that weaken rent repayment order applications
A lot of applications fail because the evidence does not prove the offence clearly enough, even when it did happen.
Missing months in rent payment records If you have three months of bank statements and a six-month claim period, the tribunal will only award for the months you can prove. Pull statements for the full period before you apply.
No direct link between the offence and the tenancy period You need to show the offence was happening while you were paying rent. An enforcement notice dated six months after you moved out proves nothing about your tenancy. Check the dates on every document and make sure they overlap with your occupation period.
Confusing the offence category Claiming for an "unlicensed property" when the correct category is "unlicensed HMO" gives the wrong legal basis (section 72(1) of the Housing Act 2004 for HMOs, section 95(1) for selective licensing) and a weaker statement of case. These are legally distinct. Confirm which applies before filing.
Submitting disorganised bundles The tribunal is not going to sort your documents for you. A 40-page bundle with no index, no page numbers, and no clear structure will irritate the judge and obscure your strongest evidence. Number every page. Include an index at the front.
Applying out of time The application window from the date of the offence is strict. It is two years for offences on or after 1 May 2026, or 12 months for earlier offences. If you are approaching the limit, apply now and supplement the evidence later rather than waiting until your bundle is perfect. A late application cannot be saved by strong evidence.
Start collecting your evidence now, even if you are not sure yet whether to apply. Bank statements, tenancy agreements, council correspondence, and photographs are easier to gather before memories fade and accounts are closed. The application window moves faster than most tenants expect.
If you're unsure whether your documents prove the offence, Remedy can check which offence category fits and help you annotate each document into an indexed bundle.
