HMO properties with 5 or more occupants require a mandatory licence from the local authority—unlicensed HMOs can face fines of up to £30,000 and rent repayment orders from tenants.

House in Multiple Occupation (HMO) legislation in the UK is stringent to ensure tenant safety in high-density housing. Under national law, any property occupied by five or more people forming two or more separate households who share basic amenities (kitchens, bathrooms) requires a mandatory HMO licence from the local council.

To secure a licence, the property must meet strict minimum room size standards (e.g., 6.51 sqm for a single adult) and robust fire safety regulations, including interlinked fire alarms and fire doors. Crucially, many councils have also introduced 'Additional Licensing' schemes, which can require licences for smaller HMOs (e.g., 3 or 4 occupants). Operating an unlicensed HMO is a criminal offense, carrying unlimited fines and allowing tenants to apply for a Rent Repayment Order (RRO) to claw back up to 12 months of rent.
