What is an HMO and what are the licensing rules?

This guidance applies to England unless stated otherwise. A House in Multiple Occupation (HMO) is defined under the Housing Act 2004 as a property occupied by three or more people forming two or more separate households, who share basic amenities such as a kitchen, bathroom, or toilet. Common examples include shared student houses, bedsit properties, and houses converted into bedsits. HMOs are subject to more stringent regulation than standard tenancies because of the increased risk associated with multi-occupancy. Mandatory licensing applies to any HMO occupied by five or more people forming two or more households in England. This requires the landlord to apply to the local council for a licence, which sets out conditions relating to the management and physical standards of the property — including room sizes, fire safety equipment, and waste facilities. Many councils have also introduced additional or selective licensing schemes for smaller HMOs or particular areas, so landlords should check with their local authority. Operating an HMO without a required licence is a serious matter. Local authorities may impose civil penalties of up to £30,000 or may prosecute certain offences in the magistrates' court — the specific consequences depend on the nature of the breach and the local authority's approach. Tenants in an unlicensed HMO may be able to apply for a Rent Repayment Order, requiring the landlord to repay up to 12 months' rent. Tenants can check whether their HMO is licensed by contacting their local council. This information is general guidance only and does not constitute legal advice.
