HMO compliance and licensing guide for England
A practical guide for landlords and agents covering HMO definitions, licensing, management duties, room-size rules, safety evidence and local-authority checks.
Start with the property, occupiers and local authority
HMO compliance is not a single certificate. The correct route depends on how the property is occupied, how many households are involved, whether facilities are shared, whether the property falls within mandatory or additional licensing, and the standards imposed by the local council.
For the common shared-house case in England, a property is generally an HMO where at least three tenants live there, form more than one household and share toilet, bathroom or kitchen facilities. A large HMO normally involves at least five tenants forming more than one household and sharing facilities. Large HMOs require a licence, while councils can also introduce additional licensing for smaller HMOs.
1. Confirm HMO status
Record who occupies the property, how households are formed and which facilities are shared. Do not assume that calling a property a “house share” settles its legal status.
2. Check the council scheme
Use the property postcode to check the relevant council. Mandatory licensing is national, but additional licensing areas, fees, local standards and application evidence vary by authority.
3. Build the evidence file
Keep licensing documents, safety records, inspection reports, occupancy information, maintenance actions and council correspondence against the property.
When is an HMO licence required?
GOV.UK states that a large HMO requires a licence where it is rented to five or more people who form more than one household, some or all occupants share toilet, bathroom or kitchen facilities, and at least one occupant pays rent or their employer pays it. A council can also require smaller HMOs to be licensed through an additional licensing scheme.
A licence is granted for a maximum of five years, must be renewed before expiry and is property-specific. The council sets the fee and can impose additional conditions within its legal powers.
London point: do not assume one borough’s licensing scheme applies across London. Check the council for the actual property address before marketing, letting, renewing or changing occupancy.
Mandatory licence conditions and suitability
Licensed HMOs must be suitable for the number of occupiers, and the licence holder or manager must satisfy the council’s fit-and-proper-person requirements. Mandatory conditions also cover matters such as smoke alarms, gas safety evidence and the safety of electrical appliances supplied by the landlord. Councils can add property-specific conditions where permitted.
The licence should therefore be treated as an operating document, not something filed away after approval. Track its conditions, expiry date, occupancy limits and any works or evidence the council requires.
National minimum sleeping-room sizes
For licensed HMOs in England, the 2018 mandatory-conditions regulations introduced national minimum sleeping-room sizes. The statutory minimum is 6.51 m² for one person aged 10 or over, 10.22 m² for two people aged 10 or over, and 4.64 m² for one child under 10. Floor area where the ceiling height is below 1.5 metres is excluded from the calculation.
These figures are minimum national thresholds, not a guarantee that a room will be accepted for a particular occupancy. Local authorities can apply higher standards and licence conditions, so the council’s current requirements still need to be checked.
HMO management duties continue beyond licensing
The Management of Houses in Multiple Occupation (England) Regulations 2006 impose day-to-day management duties on many HMOs, including HMOs that do not require a licence. The duties cover providing manager information to occupiers, safety measures, water supply and drainage, gas and electricity, common parts, fixtures and fittings, living accommodation and waste disposal.
Converted blocks falling within section 257 of the Housing Act 2004 are subject to separate management provisions, so property type matters. Where the building configuration is unusual, establish which regime applies before relying on a generic HMO checklist.
Fire, gas and electrical evidence
HMO compliance normally brings several safety workstreams together. Fire precautions and escape routes must be maintained appropriately for the property; gas installations and landlord-supplied appliances must be managed in line with gas-safety duties; and electrical installations in the private rented sector require periodic inspection and testing at intervals not exceeding five years unless a shorter interval is specified.
For a licensed HMO, the council may ask for specific evidence as part of the application or licence conditions. Keep current reports and certificates accessible rather than rebuilding the evidence file only when renewal approaches.
A practical HMO compliance file
- licence application, licence, conditions and expiry date
- occupancy and household information
- room measurements and permitted occupancy
- gas safety records and follow-up actions
- EICR and electrical remedial evidence
- fire-safety inspection, alarm and maintenance records where applicable
- evidence for landlord-supplied appliances and furnishings where required
- maintenance and repair records for common parts and shared facilities
- waste-storage arrangements and relevant council requirements
- correspondence with the local authority and evidence of completed licence conditions
2026 tenancy-law note
England’s private-rented tenancy framework changed on 1 May 2026 under the Renters’ Rights Act 2025. Those tenancy reforms sit alongside, rather than replace, HMO licensing and property-safety duties. Landlords and agents should therefore keep tenancy-management processes current while separately checking HMO licensing, licence conditions and safety obligations.
A better portfolio workflow
For each HMO, record the licensing authority, scheme type, application date, licence number, expiry date, occupancy limit, room limits, key safety renewal dates and outstanding conditions. For portfolios spanning several boroughs, keep the local-authority rules against each property instead of relying on one London-wide template.
This makes it easier to identify what is due, what evidence is missing and which properties need technical inspection, remedial work or licence action before a deadline is reached.
This guide is a practical overview for England and is not a substitute for property-specific legal, licensing or technical advice. HMO status, planning, licensing schemes, amenity standards and licence conditions can depend on the building, occupation and local authority.
