Is my home a house in multiple occupation, and does it need a licence?

This matters to tenants for two reasons. Unlicensed operation is an offence, and in England and Wales it also opens routes for tenants to reclaim rent. And licensing brings enforceable standards — amenities, fire safety, room sizes and management duties — which is often the fastest way to get a badly run shared house improved.

Step by step

1. Apply the basic test.Three or more people forming more than one household, sharing a kitchen, bathroom or toilet, with the property as their only or main residence. A household is a single person, a couple, or a family group — so three friends are three households.
2. England: check both national and local licensing.Mandatory licensing applies to larger HMOs under the Housing Act 2004. Councils can also designate additional HMO licensing and selective licensing schemes covering ordinary lettings in defined areas, and since December 2024 they no longer need central approval to do so. Check your council's website by postcode.
3. Wales: check both Rent Smart Wales and the council.Every Welsh landlord must register with Rent Smart Wales, and a licence is additionally required if they carry out letting or management work themselves. On top of that, councils operate HMO licensing schemes under the Housing Act 2004.
4. Scotland: the threshold is lower and national.Any property occupied by three or more unrelated people sharing facilities requires an HMO licence from the council, granted for up to three years, in addition to the landlord being on the council's landlord register.
5. Northern Ireland: one unit licenses for all councils.The Houses in Multiple Occupation Act (NI) 2016 applies where three or more people from more than two households live together. Licensing is administered by the NIHMO unit hosted by Belfast City Council on behalf of all eleven councils.
6. Look the property up.Councils publish HMO licence registers. Search by address. If it should be licensed and is not, that is worth knowing before you sign and worth reporting after you have.
7. Know what a licence brings with it.Conditions on amenities, fire detection and escape, gas and electrical safety, room sizes, waste, and the manager being a fit and proper person. Those conditions are enforceable by the council on your behalf.
8. Understand the consequences for an unlicensed landlord.Operating without a required licence is an offence with substantial penalties everywhere. In England and Wales it can also support a rent repayment order, and it affects the validity of a landlord's possession routes.
9. Report a problem to the right team.The council's private sector housing or environmental health team, not the police. They inspect, serve notices and prosecute, and they deal with unlicensed HMOs routinely.
10. Check before you take a lodger yourself.If you rent and take in a lodger, or if a household grows, a property can become a licensable HMO without anyone intending it. Ask the council before rather than after.

Tips

• Search the council's public HMO register before you sign. It is free and it tells you a great deal about how the property is run.
• Photograph the fire doors, alarms and escape route on the day you move in. It is the evidence a council officer will ask for.
• If the property should be licensed and is not, take advice before you complain, so you know what you can recover and what protection you have.

Common mistakes

• Counting people rather than households — The test is households sharing facilities, so a couple counts once. Getting this wrong in either direction leads to the wrong answer about licensing.
• Assuming a national rule — England has mandatory, additional and selective licensing that varies street by street; Scotland's threshold is lower and uniform; Northern Ireland runs a single scheme for all councils. Check your own council.
