HMO Licensing in England: Mandatory and Local Scheme Checks

An HMO and a licensable HMO are not identical. In England, a property is commonly an HMO where at least three people from two or more households share a toilet, bathroom or kitchen. A large HMO occupied by five or more people from two or more households normally requires a mandatory licence. A council can also require smaller HMOs to hold an additional licence.

Always check the exact address with the local council before letting. Scheme boundaries, start dates, fees, standards and evidence differ, and selective licensing can cover non-HMO rentals too.

The three licensing questions

Question	National starting point in England	Required action
Is it an HMO?	Usually 3+ people, 2+ households and shared basic facilities	Check the legal property category and any exemptions
Is mandatory licensing triggered?	Usually 5+ people from 2+ households sharing facilities	Apply to the council before operating unless a valid exception applies
Is there a local scheme?	Additional schemes can license smaller HMOs; selective schemes can cover other rentals	Search the council's current designations using the property address

Count households, not only tenants

A household can be one person or members of the same family living together. A couple counts as one household; that couple plus an unrelated friend normally represents two. Five unrelated sharers are normally five households. Do not assume everyone on one joint tenancy becomes one household.

Record the intended occupants, relationships, tenancy/licence structure and facilities they share. Buildings converted into flats, flats in small purpose-built blocks, hostels, resident-landlord arrangements and section 257 HMOs need closer classification.

Mandatory licensing has no three-storey requirement

The old “three or more storeys” shortcut is obsolete in England. Since October 2018, mandatory licensing generally covers HMOs with five or more occupants from two or more households regardless of storey count, subject to the detailed legal description and exclusions.

Additional and selective licensing

An additional licensing designation can require a licence for three- or four-person HMOs below the mandatory threshold. A selective licensing designation can require licensing for other private rented properties in a defined area. Councils can renew, vary or replace schemes, so an old postcode blog or agent checklist is not sufficient evidence.

1. Identify the local housing authority for the property postcode.
2. Open its current property-licensing page and scheme maps.
3. Check whether the address falls inside a live designation on the intended tenancy start date.
4. Ask the council in writing if the property type or boundary is unclear.
5. Keep the response, map and application receipt with the compliance record.

What the council considers

The council must be satisfied that the property is suitable for the proposed number of occupants and that the licence holder and manager are fit and proper. The application can require ownership, management, occupancy, room, amenity, safety and financial information. A managing agent may apply, but using an agent does not remove the need to identify who legally has control and management responsibility.

A licence is valid for a maximum of five years and must be renewed before expiry. A separate licence is generally required for each HMO. Fees are set locally and can be staged or varied according to the property and application.

National minimum sleeping-room sizes

For licensed HMOs in England, the prescribed minimum sleeping-room floors are 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 ceiling height is below 1.5 m is excluded from the calculation.

These are absolute national minima, not automatic approvals. A council can impose larger standards or a lower occupancy based on layout, amenities and local policy. Measure accurately and obtain the council's current standards before buying or converting.

Common licence conditions

• annual gas-safety certification where gas is present;
• installed and maintained smoke alarms and other fire precautions;
• electrical-appliance safety evidence where requested;
• adequate kitchens, bathrooms, refuse storage and communal management;
• maximum occupants and households for the property and rooms; and
• compliance with local amenity, waste and management conditions.

Licensing is not a substitute for the Housing Health and Safety Rating System, repair duties, gas/electrical rules, smoke and carbon-monoxide alarms or HMO management regulations.

Planning permission is a separate gate

An HMO licence does not grant planning permission. Moving from a family home to a small HMO may fall within permitted development in some areas, but an Article 4 direction can remove that route. Larger HMOs and material changes of use can require an application. Check planning use, building regulations and licensing separately before committing to a layout or tenancy.

If a licence is missing

Operating a licensable HMO without the required licence can lead to prosecution or a civil financial penalty. Tenants or a council can also seek a rent repayment order where the legal conditions are met; current post-reform guidance covers repayment of up to 24 months for relevant offences. Licensing failures can also affect possession proceedings and whether a person remains fit and proper.

Do not wait for an inspection after tenants move in. If a licence should already exist, obtain specialist advice, contact the council and correct the position rather than hiding occupancy or backdating records.

Application preparation checklist

• property title, mortgage/lease permissions and planning-use check;
• scaled floor plans with room dimensions and ceiling-height exclusions;
• proposed occupants, households and letting arrangements;
• fire-risk evidence, alarm layout and escape-route information;
• gas, electrical and appliance safety records;
• kitchen, bathroom, refuse and amenity schedule;
• manager, licence-holder and ownership details;
• existing licences, enforcement notices and planning decisions;
• council scheme, fee, document and fit-and-proper requirements; and
• application confirmation and renewal date.
