Mandatory licensing, room sizes, fire safety, and management regulations for houses in multiple occupation in England.
England only. This guide applies to private rented property in England. Wales and Scotland have separate legal frameworks — dedicated guides will be published separately.
A house in multiple occupation (HMO) is a property rented to multiple households who share basic amenities. In England, the definition covers any property with three or more tenants from two or more households sharing a kitchen, bathroom, or toilet.
HMOs are subject to additional licensing, management, and safety regulations beyond standard single-let requirements. Letting agents managing HMO portfolios need robust compliance tracking across every room and shared area.
| Licence type | When required | Who issues |
|---|---|---|
| Mandatory licence | 5+ occupants from 2+ households | Local housing authority |
| Additional licensing | Council designates area (e.g. all HMOs) | Local housing authority |
| Selective licensing | Council designates area (any private let) | Local housing authority |
Licence applications require floor plans, fire safety measures, amenity standards, and fit-and-proper person checks. Licences typically last five years and are not transferable on sale.
| Occupancy | Minimum floor area |
|---|---|
| 1 person | 6.51 m² |
| 2 people | 10.22 m² |
| Cannot be used for sleeping | Under 4.64 m² |
Ceiling height must be at least 1.5 m over at least half the room floor area. Local authorities may impose higher standards through additional licensing conditions.
The Management of Houses in Multiple Occupation (England) Regulations 2007 impose ongoing duties on managers (landlords or agents) including maintaining common areas, providing waste disposal, displaying manager contact details, and ensuring gas and electrical safety.
| Offence | Penalty |
|---|---|
| Operating unlicensed HMO | Unlimited fine (criminal) |
| Breach of licence conditions | Civil penalty up to £30,000 |
| Rent repayment order | Up to 12 months' rent repayable to tenants |
| Management order | Council takes over property management |
A house in multiple occupation (HMO) is a property rented by three or more people from two or more households who share a kitchen, bathroom, or toilet. A property with five or more occupants from two or more households requires mandatory HMO licensing.
Since 1 October 2018, single occupancy rooms must be at least 6.51 m² and rooms for two people at least 10.22 m². Rooms under 4.64 m² cannot be used for sleeping. Local authorities can set higher standards.
HMOs must have mains-wired interlinked smoke alarms on every floor, heat detectors in kitchens, fire doors with self-closing devices on escape routes, and a fire risk assessment. Additional licensing schemes may impose stricter requirements.
No. Operating an unlicensed HMO where licensing is required invalidates any Section 21 notice and may prevent Section 8 claims. Licence the property before taking any possession action.
Criminal prosecution with unlimited fines, civil penalties up to £30,000 per offence, rent repayment orders (up to 12 months' rent), and management orders where the council takes over management of the property.
Yes. HMO landlords must comply with both HMO-specific regulations and the wider reforms in the Renters' Rights Act 2025, including periodic tenancies and Section 8-only possession from May 2026.
