Find out which notice you need
  • It is occupied by 3 or more people forming 2 or more households
  • They share one or more basic amenity (bathroom, toilet, or cooking facilities)
  • It is their only or main residence
  • Rent is paid (or there is another form of consideration)

What Counts as a Household?

A household is generally:

  • A single person
  • A couple (married, civil partners, or cohabiting)
  • A family with children
  • Related people living together

Three unrelated friends sharing a house would be three separate households, making the property an HMO.

Mandatory HMO Licensing

Mandatory HMO licensing applies across all of Wales. You must have a licence if your property:

  • Is occupied by 5 or more people
  • Forming 2 or more households
  • Has shared facilities

No Storey Requirement

Unlike the previous rules, there is no longer a requirement that the property be three or more storeys. All HMOs with 5+ occupants need a licence regardless of building height.

Additional Licensing Schemes

Local authorities in Wales can introduce additional licensing schemes that require smaller HMOs to be licensed. These schemes vary by area.

Additional licensing might require a licence for:

  • All HMOs with 3+ occupants in certain areas
  • Specific property types (e.g., converted buildings)
  • Properties in designated areas with housing problems

Check with your local authority to see if additional licensing applies to your property. Areas with high student populations often have additional licensing schemes.

HMO Standards and Requirements

HMOs must meet specific standards beyond normal rental properties:

Fire Safety

  • Fire doors on all rooms opening onto escape routes
  • Fire detection systems (often Grade A or higher)
  • Emergency lighting on escape routes
  • Fire blankets in kitchens
  • Fire extinguishers in communal areas
  • Clearly marked escape routes

Kitchen Facilities

  2. Provide floor plans showing room sizes and facilities
  3. Submit evidence of fire safety measures
  4. Provide gas and electrical safety certificates
  5. Pay the application fee

Licence Duration

HMO licences in Wales are typically granted for 5 years. You'll need to renew before expiry to continue letting the property as an HMO.

Fees

HMO licence fees vary by local authority. Typical fees range from £500 to £1,500 for a 5-year licence. Check with your local council for exact fees.

Wales HMO FAQ

Do I need planning permission for an HMO?

Possibly. In some areas, a change of use from C3 (dwelling) to C4 (small HMO) or Sui Generis (large HMO) requires planning permission. Check with your local planning department, especially in Article 4 direction areas.

What happens if I let an unlicensed HMO?

You can be prosecuted and fined up to £30,000 per offence. Additionally, tenants can apply for a Rent Repayment Order to recover up to 12 months' rent. You cannot evict tenants using Section 173 until the HMO is licensed.

Do I need separate occupation contracts for each room?

Yes. Under the Renting Homes (Wales) Act, each contract-holder needs their own written statement of occupation contract. You should issue individual contracts even if tenants share common areas.

Can the council impose conditions on my licence?

Yes. Licences often come with conditions such as maximum occupancy numbers, requirements for specific safety measures, or management standards. Breaching conditions is an offence.

What about Rent Smart Wales?

HMO landlords must still register with Rent Smart Wales AND obtain a licence if they manage the property themselves. The HMO licence and RSW licence are separate requirements.
