If I purchase an existing unlicensed HMO that should be licensed, what are the legal risks to me as a new landlord, and can I transfer or retrospectively apply for the license?

Quick Answer

Buying an unlicensed HMO can lead to unlimited fines, rent repayment orders, and possession difficulties. Licenses are non-transferable; new owners must apply for their own license immediately upon purchase.

## Legal Risks of Purchasing an Unlicensed HMO Operating an HMO that should be licensed without one exposes a landlord to substantial legal and financial penalties. From April 2025, mandatory HMO licensing applies to properties with 5 or more occupants from 2 or more households. If you acquire such a property without a license, you are immediately in breach of regulations. ### What are the immediate risks for a new landlord? The immediate risks for a new landlord purchasing an unlicensed HMO include criminal prosecution, unlimited fines, and rent repayment orders. Local authorities can prosecute landlords for operating an unlicensed HMO, with severe penalties. Additionally, tenants can apply for a Rent Repayment Order (RRO), demanding up to 12 months' rent back, which can amount to tens of thousands of pounds. For example, a property generating £3,000 per month in rent could face a £36,000 RRO. Mortgage lenders may also withdraw or refuse financing if the property is found to be operating illegally, impacting your financial stability. ### Can an existing HMO license be transferred to a new owner? No, an existing HMO license cannot be transferred to a new owner; they are personal to the license holder and the property. Upon purchasing an HMO, the new owner must submit a new license application to the local council. The previous owner's license becomes invalid on the date of sale, meaning the property immediately becomes unlicensed under your ownership if a new application is not in place. According to government guidance, new landlords must apply for a license before or immediately after taking ownership to avoid a period of non-compliance, which could lead to significant financial penalties up to £30,000. ### Is retrospective application possible for an HMO license? Yes, it is possible to apply for an HMO license retrospectively, although this does not negate the period of non-compliance. A new landlord must apply for a license as soon as possible after acquiring an HMO that requires one. While applying will demonstrate intent to comply, any period the property was operated without a license under your ownership remains an offence. Local councils have discretion in enforcement, but the obligation to be licensed falls to the current owner. If conditions are not met, the application could be rejected, further prolonging the unlicensed period and increasing risk. For instance, if minimum room sizes (e.g., single bedroom 6.51m², double 10.22m²) are not met, significant remedial work may be required before a license is granted. ### What are the consequences for possession proceedings? Operating an unlicensed HMO carries consequences for possession proceedings against tenants. If you operate an HMO that requires a license but does not have one, you cannot serve a valid Section 21 Housing Act notice to gain possession of the property. This means you could be unable to legally evict tenants, even if they breach tenancy terms. This severely impacts your ability to manage your investment and can lead to extended periods of unrecoverable possession. The upcoming abolition of Section 21 by the Renters' Rights Bill in 2025 will further complicate possession, reducing the options available to landlords.

Steven's Take

Acquiring an unlicensed HMO is a major red flag that needs immediate attention. I’ve seen new investors inherit massive problems simply by not verifying the license status pre-purchase. The legal and financial exposure from unlimited fines and rent repayment orders can wipe out any perceived bargain. Never assume an existing HMO is compliant; always check with the local authority and factor in the time and cost for a new license application. This isn’t a grey area; it’s a strict legal requirement that must be handled properly from day one.

What You Can Do Next

  1. Verify HMO license status: Before purchase, contact the local council's housing or HMO licensing department to confirm if the property is licensed, its license conditions, and if it requires one via their website or phone.
  2. Factor in license costs and remedial work: Estimate costs for a new HMO license application (typically £500-£1,200) and any necessary works, e.g., fire safety upgrades or room size adjustments, to meet mandatory standards (e.g., 6.51m² for single rooms).
  3. Engage a specialist solicitor: Seek legal advice from a property solicitor specialising in HMO law to understand your specific obligations and risks associated with the purchase.
  4. Submit new license application immediately: Upon purchase, or even before completion, formally apply for a new HMO license with the relevant local authority to minimise the period of non-compliance.
