The complete guide to HMO licensing in England, Wales, and Scotland. Find your council, check when you need a licence, and understand conditions, fees, and penalties.
HMO licensing in the UK is governed by Part 2 of the Housing Act 2004. Mandatory licensing applies across all of England and Wales — you do not need your council to designate an area for it to apply.
Under section 55 of the Act, you must have an HMO licence if your property meets all of these criteria:
The property is occupied by 5 or more people forming 2 or more separate households
Tenants share one or more basic amenities — a kitchen, bathroom, or toilet
The property is used as the occupants' only or main residence and rent is payable
The property is not exempt — for example, it is not managed by a local authority, housing association, or educational institution
These thresholds were extended in October 2018 to include all qualifying HMOs regardless of how many storeys they have. Before this change, mandatory licensing only applied to properties of 3 or more storeys.
Not sure if your property qualifies? Use our free HMO licence checker to find out whether you need a mandatory or additional licence, or check our guide to HMO licensing exemptions.
Many landlords are caught out by local licensing schemes that go beyond the mandatory rules. Even if your property has fewer than 5 occupants, you may still need a licence.
Under section 56 of the Housing Act 2004, councils can require HMOs that fall outside mandatory licensing to be licensed. This commonly applies to properties with 3 or 4 tenants from 2 or more households. Each council sets its own additional licensing scheme and area designation.
Under section 80 of the Act, councils can require all privately rented properties in a designated area to be licensed — not just HMOs. These schemes target areas with low demand, antisocial behaviour, or poor housing conditions. A property already under HMO licensing is exempt from selective licensing.
For a detailed comparison, see our guide to additional vs mandatory licensing. You can also use our interactive HMO licensing map to check which schemes operate in your council area, including Article 4 planning directions.
Since 1 October 2018, all HMO licences include mandatory conditions on minimum sleeping room sizes. These are set by The Licensing of Houses in Multiple Occupation (Mandatory Conditions of Licences) (England) Regulations 2018.
| Room Occupancy | Minimum Floor Area |
|---|---|
| 1 person aged 10 or over | 6.51 m² |
| 2 persons aged 10 or over | 10.22 m² |
| 1 child under 10 | 4.64 m² |
| Below 4.64 m² | Cannot be used as sleeping accommodation |
Any part of the floor where the ceiling height is below 1.5 metres is excluded from the calculation. Licence holders must notify their local authority of any room below 4.64 m². Use our room size compliance checker to verify your property meets these standards.
Every HMO licence includes a set of mandatory conditions under section 67 of the Housing Act 2004 and the 2018 Regulations. Your council may add further conditions specific to your property.
The property must be suitable for the maximum number of occupants stated on the licence
The licence holder (or their agent) must be a "fit and proper person" with no relevant criminal convictions or housing law breaches
A current gas safety certificate must be provided to the council annually
Smoke alarms must be installed on every storey and kept in proper working order
Carbon monoxide alarms must be fitted in any room with a fixed combustion appliance (since October 2022 this includes gas boilers, not just solid fuel)
Electrical appliances and furniture supplied by the landlord must be kept in a safe condition
An Electrical Installation Condition Report (EICR) must be provided when requested
Each unit of living accommodation must have sufficient waste disposal facilities
For the full list of conditions and what they mean in practice, see our detailed guide to HMO licence conditions. You can also use our fire safety checklist and EICR requirements checker to ensure compliance.
Under section 66 of the Housing Act 2004, your local council must assess whether the proposed licence holder and property manager are “fit and proper” before granting a licence. The council will consider whether you have:
Offences involving fraud, dishonesty, violence, drugs, or any offence listed in Schedule 3 of the Sexual Offences Act 2003
Practised unlawful discrimination in connection with a business on grounds of sex, race, disability, or other protected characteristics
Contravened any provision of housing law or landlord and tenant law, including previous licensing breaches
A person subject to a banning order under the Housing and Planning Act 2016 automatically fails this test
The council also considers the conduct of people associated with you, and whether the proposed management structures and funding arrangements are satisfactory. If you use a managing agent, they must also pass the fit and proper test.
Applications are made to your local council under section 63 of the Housing Act 2004. Each council sets its own process and fees, but the steps are broadly similar.
Check whether your property needs a licence and request the application form. Your council will confirm which scheme applies and what documents are needed.
Prepare your gas safety certificate, EICR, floor plans showing room measurements, fire risk assessment, and proof of identity. Some councils require planning permission evidence.
Complete the application and pay the Part A fee. If approved, you pay the Part B fee on grant. Licences last up to 5 years.
HMO licence fees typically range from £500 to £1,500 for a mandatory licence, though some London boroughs charge per habitable room and can exceed £2,000. Processing times vary from 4 to 12 weeks depending on your council.
Operating an unlicensed HMO when one is required is a criminal offence under section 72 of the Housing Act 2004. The consequences are severe and can come from multiple directions.
| Penalty | Details |
|---|---|
| Criminal prosecution | Unlimited fine on conviction in the magistrates' court |
| Civil penalty | Up to £30,000 per offence (rising to £40,000 from May 2026 under the Renters' Rights Act 2025) |
| Rent repayment order | Tenants or the council can apply to the First-tier Tribunal for repayment of up to 12 months' rent |
| Banning order | The council can apply for a banning order preventing you from letting property or acting as an agent |
| Breach of licence conditions | Also an offence under section 72(3) — unlimited fine on conviction |
A council cannot both prosecute and impose a civil penalty for the same offence — it must choose one. Rent repayment orders under the Housing and Planning Act 2016 (sections 40–52) can be pursued separately by tenants, regardless of council action. For the full picture, see our guide to HMO licensing penalties.
HMO licensing and planning permission are separate requirements. Even if you have a licence, you may still need planning permission to use a property as an HMO.
Normally, converting a dwelling (use class C3) to a small HMO of up to 6 people (use class C4) is permitted development and does not require planning permission. However, many councils have removed this right using Article 4 directions, meaning you need to apply for planning permission before converting a property to HMO use.
Larger HMOs with 7 or more occupants fall into sui generis use and always require planning permission, regardless of Article 4.

The Renters' Rights Act received Royal Assent on 27 October 2025 and its main provisions come into force on 1 May 2026. While the core HMO licensing framework under the Housing Act 2004 remains unchanged, several changes directly affect HMO landlords:
The maximum civil penalty for housing offences rises from £30,000 to £40,000
No-fault evictions are banned entirely — all existing assured shorthold tenancies convert to periodic
No new fixed-term tenancies can be created. Rent can only be increased once per year via the section 13 procedure
Liability for unlicensed HMOs can extend to freeholders of converted blocks, not just the managing landlord
RROs apply to additional offences under the new Act
The fundamental licensing criteria — 5+ occupants, 2+ households, shared facilities — remain the same under the 2026 changes.
HMO licensing rules differ across the UK. If your property is in Scotland or Wales, different thresholds and legislation apply.
Scotland has a lower licensing threshold: any property rented to 3 or more people from 2 or more households requires a licence. This is governed by the Housing (Scotland) Act 2006, not the Housing Act 2004. Licences are issued by the local authority and last up to 3 years.
Scotland HMO licensing guide →Wales follows the same Housing Act 2004 framework as England for HMO licensing. However, the Renting Homes (Wales) Act 2016 replaced assured shorthold tenancies with occupation contracts, which affects tenancy management in licensed HMOs. Landlords must also register with Rent Smart Wales.
Wales HMO licensing guide →Housing Act 2004, Part 2 (sections 55–78)
Maximum 5 years, must be renewed before expiry
One licence required per HMO property
Typically £500–£1,500, set by each local council
6.51 m² (1 adult), 10.22 m² (2 adults), 4.64 m² (1 child under 10)
Unlimited fine for operating without a licence
Up to £30,000 per offence (£40,000 from May 2026)
3+ people from 2+ households (lower than England)
The UK has four home nations—England, Wales, Scotland, and Northern Ireland—each with its own local authorities responsible for HMO licensing and planning. England has the most councils and the widest variety of additional and selective licensing schemes.
