Do I need an HMO licence for 3 tenants?

Three different tests are often confused

An HMO is generally a property occupied by at least 3 people who form more than one household and share facilities such as a kitchen or bathroom. That is the classification question.

Mandatory licensing is a separate question. GOV.UK describes a large HMO as one occupied by 5 or more people from more than one household, with shared facilities and rent being paid. The national threshold is not the end of the analysis: a council may operate an additional licensing scheme that covers smaller HMOs.

The practical three-tenant check

Are the occupiers from one household or separate households?
Do they share a kitchen, bathroom or toilet?
Is at least one person paying rent or is rent paid for them?
Does the council have an additional licensing designation covering this property type?
Does a selective licensing designation apply even if the property is not an HMO?
Are there planning, fire-safety, management or occupancy conditions in the local area?

Do not use ‘three tenants’ as a way around safety duties

Whether or not a licence is required, landlords and managers still need to comply with applicable housing, fire, gas, electrical and management requirements. A property that falls below mandatory licensing can still be an HMO and can still be subject to enforcement.

What to keep before letting

Save the council's current licensing page or designation, the floor plan, the occupancy calculation, the tenancy structure and safety certificates. If the council gives a written answer, keep the question as well as the reply so the assumptions remain clear.

Questions people ask

Can 3 people live in a non-HMO?

Three unrelated people sharing facilities may meet the HMO definition even if the property is not a large HMO requiring mandatory licensing. The local council's additional licensing scheme may still require a licence.

How many tenants before an HMO licence is mandatory?

The national mandatory licensing description generally uses 5 or more people from more than one household sharing facilities, but smaller HMOs may be covered by additional licensing. Check the council rather than relying on the national threshold alone.

Can I avoid an HMO licence by calling the occupiers lodgers?

A label in an agreement does not decide the legal classification. The facts of occupation, households, facilities and rent matter. Obtain council guidance where the arrangement is not straightforward.
