What Is an HMO?

An HMO is a property rented to 3 or more tenants from 2 or more separate households who share facilities such as a kitchen or bathroom. HMOs generate significantly higher yields than single-let properties — typically 10-18% gross — because you rent by the room rather than the whole property.

Licensing

Mandatory Licensing: Required for HMOs with 5 or more people from 2 or more households, regardless of the number of storeys. Costs typically £500-1,500 per licence, valid for up to 5 years.

Additional Licensing: Many councils operate schemes covering smaller HMOs (3-4 people). Check your local authority's website.

Selective Licensing: Some areas require all rented properties to be licensed, not just HMOs.

Minimum Room Sizes

Room UseMinimum Size
Single bedroom (1 person aged 10+)6.51 m²
Double bedroom (2 persons aged 10+)10.22 m²

HMO Fire Safety

  • Fire doors to all bedrooms, kitchens, and living rooms (FD30S rated, self-closing)
  • Interlinked fire detection system (Grade A in larger HMOs)
  • Emergency lighting on escape routes
  • Fire blanket in the kitchen
  • Fire extinguishers on each floor
  • Clear, unobstructed escape routes
  • Fire risk assessment reviewed annually

Renters' Rights Act 2025 — HMO Impact

The Renters' Rights Act 2025 has significant consequences for HMO landlords specifically:

  • All new tenancies are periodic — fixed-term ASTs can no longer be issued for HMO rooms. Tenants can give 2 months' notice to leave at any point, including mid-academic-year for student HMOs.
  • Section 21 abolished — you can no longer serve a no-fault notice on an HMO tenant. Possession requires a specific Section 8 ground (e.g. rent arrears, antisocial behaviour, or selling the property).
  • PRS Ombudsman registration is mandatory — HMO landlords must register individually with the PRS Ombudsman. Failure is a criminal offence carrying a fine of up to £5,000 per property.
  • Pet requests — tenants in HMO rooms have the right to request a pet. You must respond within 28 days and cannot unreasonably refuse.
  • Rent increases — you can only increase room rents once per year via the Section 13 statutory process, with at least 2 months' written notice.

EPC and the 2030 Deadline

The government has confirmed that all rental properties in England must achieve an EPC C rating by 2030. For HMOs this is particularly challenging — communal areas, multiple rooms, and older building stock mean upgrade costs are typically higher than single-let properties.

  • Check the current EPC rating before purchasing any HMO — a D or E rating requires a retrofit plan.
  • Common upgrades: loft/wall insulation, double glazing, heat pumps, LED lighting throughout communal areas.
  • Average cost to upgrade from D to C: £6,500–£15,000+ for a 4–5 bed HMO.
  • A property that cannot achieve C may not be legally lettable after 2030 — price this risk into your acquisition model.
