HMO Licensing — An Honest Primer for New Landlords

A House in Multiple Occupation is a property rented out to three or more people from more than one household who share facilities. In England two layers of licensing can apply.

Mandatory licensing

A mandatory HMO licence is required whenever the property is occupied by five or more people forming more than one household, regardless of the number of storeys. Operating without one is one of the most heavily penalised housing offences on the books.

Additional and selective licensing

Many councils operate additional licensing schemes that reach down to smaller HMOs (three or four sharers). Some apply selective licensing across whole wards. These rules change from one authority to the next, so the first move is always to check the position where the property sits.

Planning: the quiet trap

Licensing and planning are separate regimes. A small HMO usually falls within use class C4, and moving between a standard dwelling and C4 is often permitted development — but not in Article 4 areas, where planning permission is needed on top of any licence. Many of the UK's best HMO neighbourhoods now sit under Article 4 directions. Don't assume.
