HMO licensing is one of the most misunderstood areas of landlord compliance. Many landlords with large shared houses do not realise their property falls within the mandatory licensing threshold. Others operating smaller shared houses in areas with additional or selective licensing schemes need a licence but are unaware their local authority operates one.
The key question is whether your property meets the definition of an HMO and whether it crosses the licensing threshold. Getting this wrong is expensive: the civil penalty for operating without a licence is up to £40,000 (raised from £30,000 by the Renters' Rights Act 2025 from 1 May 2026), and an unlicensed HMO landlord is vulnerable to a rent repayment order application from tenants.
| Item | Detail |
|---|---|
| Mandatory licence | 5+ occupants, 2+ households, a shared amenity |
| Additional licensing | Smaller HMOs in designated council areas |
| Selective licensing | All private rentals in a designated area |
| Typical fee | £500–£1,500 (varies by council) |
| Licence length | Up to 5 years |
| No licence | Up to £40,000 civil penalty + rent repayment order |
Additional and selective schemes vary by council — always check your local authority's licensing portal for your postcode.
What is an HMO?
A House in Multiple Occupation (HMO) is a property occupied by 3 or more people who form 2 or more separate households, where at least one basic amenity (toilet, bathroom, or cooking facilities) is shared. Common examples:
- A student house occupied by 4 students who are not all related, 4 people, 4 households
- A house shared by 3 or more working professionals with shared kitchen and bathroom
- A converted flat or bedsit building with shared facilities
- A property with a resident landlord and 2+ tenants sharing facilities does not qualify as an HMO for licensing purposes, the resident landlord exemption applies
Mandatory HMO licensing threshold
Mandatory HMO licensing under the Housing Act 2004 (as amended by the Licensing of Houses in Multiple Occupation (Mandatory Conditions of Licences) (England) Regulations 2018) applies to any HMO that:
- Has 5 or more occupants, AND
- Those occupants form 2 or more separate households, AND
- At least one amenity (kitchen, bathroom, toilet) is shared
- This covers all storeys of the building, the old 3-storey rule was removed in October 2018
- There is no minimum number of storeys, a single-storey bungalow shared by 5 unrelated people needs a mandatory licence
Additional and selective HMO licensing
Even if your property does not meet the mandatory threshold, your local authority may operate an additional licensing scheme that covers smaller HMOs (e.g. 3+ or 4+ occupants). Many councils also operate selective licensing for ALL privately rented properties in designated areas. Check your council's licensing portal:
- Additional HMO licensing: covers HMOs below the mandatory threshold in designated areas
- Selective licensing: covers all private rented properties in a designated area, not just HMOs
- Both additional and selective licences carry civil penalties of up to £40,000 for non-compliance (from 1 May 2026)
- Councils are not required to advertise additional/selective schemes, it is the landlord's responsibility to check
HMO licence conditions
A mandatory HMO licence comes with conditions set by the local authority, but minimum national standards are prescribed. Key conditions include:
- Minimum room sizes: Sleeping rooms for adults must be at least 6.51 m² (single) or 10.22 m² (double). Rooms below 4.64 m² cannot be used for sleeping
- Refuse management: Adequate provision for the storage and disposal of refuse, in practice, sufficient bins for the number of occupants
- Gas safety: Annual gas safety check (CP12), copy must be provided to the local authority on renewal
- Electrical safety: Fixed wiring inspection (EICR) every 5 years
- Smoke and CO alarms: Working smoke alarm on every floor, CO alarm in every room with a solid fuel appliance
- Fit and proper person: The licence holder and manager must be a fit and proper person, convictions for fraud, violence, or drug offences may disqualify
HMO rules and management regulations landlords must follow
Separate from the licence itself, every HMO in England, whether licensed or not, must comply with the Management of Houses in Multiple Occupation (England) Regulations 2006. These set the day-to-day duties of the person managing the HMO, and breaching them is a criminal offence in its own right, independent of whether the property is licensed. They sit alongside the minimum room size requirements covered above. The core manager duties are:
- Display the manager's details: the manager's name, address and a contact telephone number must be displayed in a prominent position inside the HMO
- Keep gas and electrics safe: maintain the gas and electricity supply, provide the latest gas safety record to the council on request, and keep the fixed wiring safe with an EICR at least every 5 years
- Fire safety: keep all means of escape clear and in good order and maintain the fire-fighting and fire-warning equipment
- Water supply and drainage: maintain a constant supply of water and proper drainage, and never unreasonably interrupt them
- Common parts, gardens and outbuildings: keep shared staircases, hallways, gardens and outbuildings clean, safe and in good repair
- Living accommodation: keep each unit and its installations clean at the start of a letting and in good repair throughout
- Waste: provide enough bins and arrange refuse removal in line with the local collection
- Converted blocks of flats that are not wholly self-contained are additionally governed by the Licensing and Management of Houses in Multiple Occupation (Additional Provisions) (England) Regulations 2007
How to apply for an HMO licence
Applications are made to the local housing authority (your council). The process varies by authority but the standard steps are:
- Check whether your property requires a licence using your council's postcode checker or licensing portal
- Complete the application form, usually online via the council's licensing portal
- Pay the application fee, typically £500-£1,500 depending on the authority and number of occupants
- Submit required documents: gas safety certificate, EICR, floor plan with room sizes, management arrangements
- The council may inspect the property before granting the licence
- Licences are typically granted for 5 years and must be renewed before expiry
Penalties for operating without an HMO licence
Operating an unlicensed HMO or breaching licence conditions carries serious consequences:
- Civil penalty: Up to £40,000 per offence from 1 May 2026 (raised from £30,000 by the Renters' Rights Act 2025), local authorities can issue civil penalties without prosecution
- Rent repayment order (RRO): Tenants (and local authorities) can apply to the First-tier Tribunal for an RRO requiring the landlord to repay up to 24 months' rent for offences committed on or after 1 May 2026 (up to 12 months for earlier offences)
- Banning order: Repeat offenders can be banned from letting properties
- Rent freeze: An unlicensed HMO landlord cannot increase rent above the rent at the date of the offence
- Possession position: Licensing non-compliance does not invalidate a Section 8 notice; before its abolition, Section 21 could not be used while an HMO was unlicensed. The financial penalties above are the real exposure
Frequently asked questions
Does a 4-bedroom student house need an HMO licence?+
It depends on occupancy. Mandatory HMO licensing applies to properties with 5 or more occupants from 2 or more households. A 4-bedroom house shared by 4 students does not require a mandatory licence, but if your local authority operates an additional licensing scheme covering 4+ person HMOs, a licence is still required. Check your council's licensing portal using the property postcode.
How long does an HMO licence last?+
HMO licences are granted for up to 5 years. Local authorities may grant shorter licences (e.g. 1 to 2 years) where there are concerns about management standards or property condition. You must apply to renew before the licence expires, operating with an expired licence is treated the same as operating without a licence.
What is the minimum room size for an HMO bedroom?+
Under the mandatory HMO licensing conditions, a room used as sleeping accommodation for a single adult must be at least 6.51 m² (70 sq ft). A room used by two adults must be at least 10.22 m² (110 sq ft). Rooms below 4.64 m² cannot be used for sleeping at all. Rooms between 4.64 m² and 6.51 m² can only be used by children under 10.
Can I manage an HMO through a letting agent?+
Yes. The licence can be held by the landlord or by a manager (including a letting agent). If the property is managed by a letting agent, the agent can be named as the licence holder and manager. Both the landlord and manager must be fit and proper persons. The licence holder remains responsible for ensuring licence conditions are met.
What happens if my HMO licence application is refused?+
If the council proposes to refuse your licence application, they must serve a 'minded to refuse' notice giving you the opportunity to make representations. If the licence is ultimately refused, you can appeal to the First-tier Tribunal (Property Chamber) within 28 days. While the appeal is pending, an interim management order may be made, effectively the council taking over management of the property.
How much does an HMO licence cost in 2026?+
The application fee is set by each local authority and typically falls between £500 and £1,500, varying with the authority and the number of occupants. Some councils split the fee into an application part and a licence-grant part, and many charge more for larger HMOs or for a renewal that needs re-inspection. The fee is only part of the cost: budget also for the gas safety check, the EICR, any works needed to meet the room-size and fire-safety conditions, and a floor plan if the council requires one.
Does every HMO need a licence?+
No. A mandatory licence is only required where the HMO has 5 or more occupants forming 2 or more households with a shared amenity. A smaller HMO still needs a licence if it sits within a council's additional licensing scheme, and any private rental can need one under a selective licensing scheme, but an HMO below the mandatory threshold in an area with no local scheme does not require a licence. Because councils are not obliged to advertise their schemes, the onus is on the landlord to check the licensing portal for the property's postcode.
