HMO licensing in Scotland, Wales and Northern Ireland

Last updated 27 Oct 2026

In Scotland, Wales and Northern Ireland a landlord needs a council licence to let a house in multiple occupation (HMO), but each nation sets its own test: three or more people from more than two families in Scotland, five or more people over three storeys in Wales, and three or more people from more than two households in Northern Ireland. This page covers those three nations only; for England see HMO and selective licensing in England.

The three regimes side by side

Nation	Who needs a licence	Licence length	Law
Scotland	Every HMO: 3 or more people who are not all one family or two families, sharing a basic amenity	3 years, or a shorter period of at least 6 months	Housing (Scotland) Act 2006, Part 5
Wales	HMOs of 3 or more storeys with 5 or more people in 2 or more households; smaller HMOs only where the council designates additional licensing	Up to 5 years	Housing Act 2004, Part 2
Northern Ireland	Every HMO: 3 or more people forming more than two households, with rent payable by at least one	5 years, or a shorter period of at least 6 months	Houses in Multiple Occupation Act (Northern Ireland) 2016, Part 2

Scotland

Section 124 of the Housing (Scotland) Act 2006 says: "Every house in multiple occupation ("HMO") must be licensed under this Part". Section 125 defines an HMO as living accommodation occupied by 3 or more persons who are not all members of the same family or of one or other of two families. The accommodation must be a house, or part of premises under common ownership where occupants share a toilet, washing or cooking facilities.

mygov.scot puts it as renting to three or more tenants where none of the tenants are related or part of the same family. The Act's test, with its two-family exception, is the one to apply.

Who applies: only the owner of the accommodation may apply, to the local council, which can grant the licence with or without conditions or refuse it (section 129).
Suitability: mygov.scot says the council checks that you pass a "fit and proper person" test and that the property is managed properly and meets the required standards.
Length: a licence expires after 3 years, or a shorter period of not less than 6 months if the licence says so (section 134).
Penalty: it is an offence for an owner to operate an unlicensed HMO without a reasonable excuse (section 154). mygov.scot says you can be fined up to £50,000.
Exemptions: section 126 lists some exempt accommodation, such as owner-occupied accommodation and some care and religious settings.

Apply through your council; mygov.scot's HMO licence page lists each council's page. It does not give fees, which councils set.

Wales

In Wales HMO licensing sits in Part 2 of the Housing Act 2004, which applies in England and Wales. Section 55 says a council must license HMOs that fall within a prescribed description, and any HMO in an area it has designated for additional licensing.

Mandatory licensing. Article 3 of the Licensing of Houses in Multiple Occupation (Prescribed Descriptions) (Wales) Order 2006 prescribes an HMO that meets all three conditions:

it, or part of it, comprises three storeys or more;
it is occupied by five or more persons;
it is occupied by persons living in two or more single households.

Basements, attics and certain other floors count towards the storeys under article 3(3). That storey test is a difference from England, where the prescribed description is not tied to storeys.

Additional licensing. Under section 55(2)(b), a council can designate an area for additional licensing of the HMO descriptions it specifies, so a smaller shared house may need a licence in one county and not in the next. Check your council's HMO pages for any current designation.

Length and penalty. A licence must not last more than 5 years after it is granted (section 68(4)). An unlicensed HMO is an offence under section 72, punishable on summary conviction by a fine.

Rent Smart Wales is separate. Rent Smart Wales covers registration and licensing under the Housing (Wales) Act 2014. The Welsh Government's Rent Smart Wales page says all landlords must register, and landlords who let or manage their own property, and those who do so for others, need a licence. An HMO licence is issued by the council under the Housing Act 2004, so a Welsh HMO landlord can need both. See landlord registration by nation.

The management duties for HMOs in Wales are in the Management of Houses in Multiple Occupation (Wales) Regulations 2006. Gov.wales also publishes guidance on licensing HMOs for landlords.

Northern Ireland

The Houses in Multiple Occupation Act (Northern Ireland) 2016 moved HMO licensing to councils. Sections 7 to 29 came into operation on 1 April 2019 (S.R. 2019/39).

Definition (section 1): a building or part of a building is an HMO if it is living accommodation, occupied by 3 or more persons as their only or main residence, those persons form more than two households, and rent or other consideration is payable by at least one of them. Schedule 1 lists exceptions.
Licence needed (section 7): every HMO must be licensed unless a temporary exemption notice under section 15 is in effect. The council for the district issues it.
Who applies (section 8): the owner, to the council. The council may grant a licence only if satisfied on planning, suitability of the owner and any managing agent, management arrangements, the number of HMOs in the area, and safety and suitability for the number of occupants.
Length (section 19): 5 years, or a shorter period of at least 6 months.
Offences: an owner with an unlicensed HMO and no reasonable excuse commits an offence under section 30, with a fine of up to £20,000 and a further £50 for every day after conviction. Claiming an HMO is licensed when it is not carries up to £10,000 (section 32), as does using a managing agent not named in the licence (section 33).

nidirect says a landlord who owns an HMO must have a licence before renting it, and that you can check whether a property is licensed with your council. Its shared accommodation page is the starting point.

How to check if your property needs a licence

Count people and households. Scotland counts families, Wales counts storeys and people, and Northern Ireland counts households.
Check the residence test. Northern Ireland counts only people for whom the house is their only or main residence, with set cases for students and seasonal workers in section 3.
Ask the council. Councils issue the licence in all three nations. Contact them before the first let, and again if you add a sharer.
Diarise the renewal. A Scottish licence runs up to 3 years, and Welsh and Northern Irish licences up to 5.

Tracking the licence with Letbook

Letbook is a compliance tracker for landlords in all four UK nations. If you mark a property as an HMO, it adds an HMO licence item to the Scottish (3-year), Welsh (5-year) or Northern Irish (5-year) checklist, with the fire risk assessment where the nation requires one, and emails you before renewal. It does not tell you whether a council has additional licensing or apply for the licence for you. Sign up free.
