Your landlord is required by law to hold a licence for your HMO. If they don't have one, you may be entitled to claim back up to 2 years of the rent you've already paid. For periods before 1 May 2026 the figure is 12 months. This is a specific right under the Housing Act 2004, and the tribunal system exists to enforce it.
A rent repayment order, or RRO, is the mechanism tenants use to recover that money. The First-tier Tribunal (Property Chamber) hears these claims and can order your landlord to repay rent covering the period when the licensing offence was being committed. In cases with serious landlord misconduct, awards have reached into the tens of thousands of pounds.
This guide covers who qualifies for a landlord unlicensed HMO rent repayment order UK claim, what evidence you'll need, how the tribunal process works, and what you can realistically expect to recover.
What makes a property an HMO requiring a licence?
An HMO is a House in Multiple Occupation: a property shared by three or more people from two or more separate households who share facilities like a kitchen or bathroom. The licensing rules split into two tiers.
Mandatory HMO licensing applies to any property with five or more occupants from two or more households. Your landlord must hold a licence from the local council to operate it legally. Additional and selective licensing schemes go further: individual councils like Hackney, Islington, and Westminster have introduced requirements covering smaller HMOs and even standard shared houses in their areas. You can read about Hackney's selective and HMO licensing rules for 2026 and Islington's selective licensing scheme for local detail.
If your landlord hasn't obtained the required licence, they are committing a criminal offence under Section 72 of the Housing Act 2004. That offence is the trigger for an RRO claim. The licence doesn't need to have lapsed by years. Even a short gap in compliance counts. From 1 May 2026 the rules expanded further. A superior landlord who committed the offence, such as one holding the property through a rent-to-rent or corporate structure, can now also face RRO liability, reversing the position in Rakusen v Jepsen where the immediate landlord could shield the superior landlord above it.
Check whether your property requires a licence by contacting your local council's housing enforcement team or by using Remedy's Landlord & Property Assessment, which checks HMO licence validity as part of its free instant case review.
How much rent can you claim back for an unlicensed HMO?
For offences committed on or after 1 May 2026 the maximum award is 2 years' rent. For offences before that date it is 12 months. Because an unlicensed HMO is a continuing offence, a licence gap running across 1 May 2026 falls under the old rules for the part before that date and the new rules for the part on or after it. Exactly how the two caps combine for a single continuing offence is still being worked out by the tribunals. Either way, the tribunal calculates the award from the rent you paid during the period of the offence, not your total tenancy.
So if you paid £1,200 per month and your landlord operated without a licence for eight months, the ceiling on your claim is £9,600. The tribunal won't automatically award the maximum. It weighs up factors including the seriousness of the offence, the landlord's conduct, whether they took steps to remedy the breach, and the condition of the property.
Landlords who ignore correspondence, fail to engage with council enforcement, or have a history of non-compliance tend to receive awards closer to the ceiling. Landlords who can show they were genuinely unaware of a licensing requirement, and acted quickly once they found out, often receive lower awards.
The financial exposure is real for landlords. Since 1 May 2026 the maximum civil penalty for a housing offence such as operating an unlicensed HMO has risen to £40,000, and a council can pursue that alongside an RRO, so a landlord can face heavy combined losses across penalties and repayments. From your side, if you've paid 12 months of rent at £1,000 per month, £12,000 may be sitting on the table.
Are you eligible to apply for a rent repayment order?
You qualify to apply if three conditions are met.
First, the property must require a licence that the landlord didn't hold. Mandatory HMO licensing is the most common route, but an additional or selective licensing requirement in your area counts too.
Second, you must have paid rent during the period when the offence was being committed. Housing benefit or Universal Credit housing payments count. You don't have to have paid from your own bank account. If housing benefit was paid directly to the landlord, the relevant local authority can also apply for an RRO, though the tenant can apply independently in parallel.
Third, you must apply in time: within 2 years of the offence ending for offences on or after 1 May 2026, or 12 months for earlier offences. This is the one that catches people out. If your landlord obtained a licence recently, count forward from that date to work out your deadline. Miss the window and the tribunal cannot hear your claim, regardless of how strong the case is.
You do not need to still be living in the property. Former tenants can apply. You also don't need to have reported the landlord to the council before applying, though doing so strengthens your evidence considerably, because council enforcement notices and correspondence are some of the clearest proof that an offence occurred. The rent repayment order route described here applies in England. Wales has its own separate scheme.
What evidence does the First-tier Tribunal need?
The standard of proof for an RRO claim is the criminal standard: beyond reasonable doubt. The tribunal needs to be satisfied that a licensing offence was committed. That sounds daunting, but in practice, licensing breaches are often easy to prove because the council keeps records.
Build your evidence bundle around these documents:
- Tenancy agreement, to confirm you were a tenant at the property and the address
- Rent payment records, bank statements, payment receipts, rent book entries
- Evidence that the property required a licence, council correspondence, the property's listing on a selective or mandatory licensing register, or a letter confirming no licence was held
- Evidence the landlord didn't hold a licence, a council enforcement notice, a written confirmation from the housing team, or a search of the public licensing register for your area
- Any relevant communications, emails or texts where the landlord acknowledged issues, or where they were warned about licensing
Photos of the property showing the number of occupants' bedrooms can also support establishing it as an HMO. If the council has already taken enforcement action, request copies of those notices under a Subject Access Request or by contacting the enforcement team directly.
Reporting the property to your local council before filing your tribunal application is worth doing. It creates a formal record of the offence, triggers enforcement activity that generates documents, and shows the tribunal you followed the correct procedure. Our guide on how to report a landlord to the council walks through that process step by step.
How to apply for a rent repayment order at the tribunal
The application goes to the First-tier Tribunal (Property Chamber) in England. You'll complete and submit form RRO1, available on GOV.UK, along with your evidence bundle and the application fee.
The form asks for: your contact details, the landlord's details, the property address, the offence you're claiming for, the period of the offence, and the rent paid during that period. Attach your evidence. The tribunal will send the application to your landlord, who can respond.
Most cases proceed to a hearing, though some straightforward cases are decided on the papers alone. Hearings are often conducted virtually. You'll present your evidence, the landlord may challenge it, and the tribunal decides both whether the offence occurred and what amount to award.
The whole process from application to decision typically takes three to five months, though this varies by tribunal workload. You don't need a solicitor. Plenty of tenants represent themselves successfully, particularly where the evidence of the licensing breach is clear.
For a full walkthrough of the application form, see our step-by-step guide to completing the RRO1 form. The same preparation principles apply to RRO applications. For broader context on what RRO grounds cover beyond licensing, the guide to rent repayment order grounds in the UK is worth reading before you file.
Common mistakes that get RRO claims dismissed
Missing the application deadline is the most common and most avoidable error. Write down when the offence ended, or when you believe it ended, and count forward from there. That deadline is 2 years for offences on or after 1 May 2026, or 12 months for earlier ones. If you're unsure when your landlord obtained a licence, ask the council. They'll tell you.
The second most common mistake is thin evidence. Saying 'I believe my landlord didn't have a licence' is not enough. The tribunal needs documentary proof. A council letter confirming no licence was registered to the property during a specific period is worth more than a stack of emails.
A third issue: applying for the wrong period. Only rent paid during the offence period is recoverable. If the landlord got a licence in month three of your tenancy, the maximum recoverable covers months one and two, not the full tenancy. Getting the dates wrong in the form can undermine the credibility of your whole application.
Finally, some tenants make the mistake of threatening an RRO application to their landlord before they've gathered evidence. Landlords who know an application is coming can move quickly to obtain backdated documentation or take steps to muddy the timeline. Gather your evidence first, file the application, then let the tribunal process inform the landlord.
