Landlord licensing in England operates under three distinct regimes created by the Housing Act 2004: mandatory HMO licensing, additional HMO licensing, and selective licensing. Each has different triggers, different coverage areas, and different enforcement powers. Understanding which regime applies to your property is the first step in compliance.
Mandatory HMO licensing
Mandatory HMO licensing under Part 2 of the Housing Act 2004 applies nationally — no local authority designation is required — to any property occupied by five or more persons forming two or more separate households, where at least one storey is shared. The key threshold is:
- Five or more people from two or more households — this covers large shared houses, professional house shares, and student houses
- The property must include at least one shared facility (kitchen, bathroom or WC)
- Purpose-built blocks of flats converted under a pre-1991 building regulations standard (Section 257 HMOs) also require licensing
- There is no upper size limit — properties of any size above the five-person threshold require a mandatory licence
- Exemptions include properties managed by local authorities and some purpose-built student accommodation managed by universities
Additional HMO licensing
Councils can designate areas for additional HMO licensing under Section 56 of the Housing Act 2004, extending licensing below the mandatory threshold. Additional licensing typically captures:
- Properties occupied by three or four unrelated people (below the mandatory five-person threshold)
- Smaller bedsit conversions and flat conversions in the designated area
- Coverage varies — each additional licensing designation specifies its own area and property types
- Designations are renewed every five years and must be confirmed by the Secretary of State if covering more than 20% of the council area
- Always check with your local council whether an additional licensing scheme is in force for your property postcode
Selective licensing
Selective licensing under Section 80 of the Housing Act 2004 can apply to all privately rented properties in a designated area, regardless of size or occupancy. Grounds for designation include:
- Low demand combined with anti-social behaviour
- Significant and persistent problems with anti-social behaviour
- Poor property conditions across the private rented sector in the area
- High levels of migration, deprivation or crime (2015 regulations)
- Current large selective licensing schemes include Newham, Southwark, Nottingham, Liverpool and many others — check the government selective licensing register for the current list
- Schemes covering more than 20% of a council area require Secretary of State confirmation and are subject to judicial review challenges
HMO licence conditions
All HMO licences carry standard conditions which the landlord must comply with throughout the licence term. Key conditions include:
- Minimum sleeping room sizes: 6.51 m² for one person, 10.22 m² for two persons sharing
- Maximum occupancy as specified on the licence
- Fire safety: Grade D LD2 fire detection and alarm system, fire doors on all bedrooms, adequate means of escape
- Annual gas safety certificate (CP12) provided to tenants within 28 days of issue
- Five-yearly EICR (electrical installation condition report)
- Adequate facilities for the number of occupants — bathrooms, WCs and kitchen provision must meet prescribed standards
- Compliance with the HMO Management Regulations 2006: drainage, water supply, refuse disposal, structural repairs
Penalties and enforcement
Non-compliance with licensing requirements carries serious financial and legal consequences:
- Criminal prosecution: unlimited fine on summary conviction in the magistrates' court
- Civil penalty: up to £30,000 per unlicensed property, issued by the local authority as an alternative to prosecution
- Rent Repayment Order (RRO): tenants (or the council) can apply to the First-tier Tribunal to recover up to 12 months' rent paid during the unlicensed period
- Management order: the council can take over management of the property via an Interim Management Order
- Rogue landlord database: criminal convictions for HMO offences are publicly recorded
- Banning order: repeat offenders can be banned from letting properties for up to five years
