Do I need an HMO licence to rent out my property as a house share?

Full answer

HMO (House in Multiple Occupation) licensing is a landlord obligation that is easy to overlook, but operating an unlicensed HMO where one is required can lead to serious financial and legal consequences. **The national mandatory HMO licensing threshold** Under national rules, a mandatory HMO licence is required if a property is occupied by 5 or more tenants forming more than one household (i.e., not all one family or one group who chose to live together as a single unit), where those tenants share amenities such as a kitchen, bathroom, or toilet. This applies regardless of how many storeys the building has (the previous 3-storey minimum requirement for mandatory licensing was removed in 2018), so even a large single-storey property meeting the 5-tenant/shared-facilities test needs a licence. **Additional and selective licensing schemes** Beyond the national mandatory threshold, individual local councils can introduce their own "additional licensing" schemes (extending HMO licensing requirements to smaller HMOs in their area, sometimes as low as 3 tenants forming 2+ households) or "selective licensing" schemes (requiring a licence for ANY rented property in a designated area, regardless of whether it is an HMO at all, often used to tackle problem areas with poor housing conditions or high levels of deprivation). This means the true licensing requirement for a specific property depends heavily on the local council's own published licensing schemes, not just the national mandatory rules. **What licensing involves** To obtain an HMO licence, a landlord must demonstrate the property meets specific size, amenity, and safety standards (adequate room sizes, sufficient kitchen and bathroom facilities relative to the number of occupants, proper fire safety measures such as fire doors, smoke alarms, and means of escape), pass a "fit and proper person" test (relating to the landlord or managing agent's own suitability, including any relevant criminal record or history of housing law breaches), and pay a licence fee to the council (which varies significantly between councils and is typically valid for up to 5 years). **Penalties for operating without a required licence** Operating an HMO without a required licence is a criminal offence, and councils can impose substantial financial penalties (civil penalties of up to £30,000 per offence in England, in addition to or instead of prosecution) as well as potential Rent Repayment Orders, requiring the landlord to repay up to 12 months of rent received to the tenants (or, in some cases, to the local authority if rent was paid via housing benefit/Universal Credit housing element), regardless of whether the property was otherwise in a reasonable condition. **Worked example** A landlord lets a large converted house to 6 unrelated young professionals sharing a kitchen and two bathrooms, without realising this meets the mandatory HMO threshold. The council's Housing Standards team investigates following a tenant complaint, confirms the mandatory licensing threshold is met, and because no licence was ever obtained, issues a civil penalty and the tenants successfully apply for a Rent Repayment Order, requiring the landlord to repay a substantial portion of the rent received during the unlicensed period, on top of now needing to urgently apply for a licence (and potentially carry out works to meet licensing standards) to continue letting the property at all. **Practical tip** Always check your specific local council's website for both mandatory HMO rules and any additional/selective licensing schemes before letting to multiple unrelated tenants, since relying only on the national 5-tenant threshold can leave you unknowingly non-compliant with a stricter local scheme.
