Overview

Additional licensing schemes let a council require a licence for HMOs that fall outside mandatory licensing, such as smaller two-storey shared houses.

Who it affects

Typically HMOs with three or four unrelated occupiers sharing facilities, below the five-occupier mandatory threshold.

Standards applied

Councils usually apply similar amenity and fire safety standards to additional licensing as they do to mandatory HMO licences.

Checking designations

Additional licensing areas vary block by block in many cities, so always confirm using the council's official designation map.

Overlap with selective licensing

A property can occasionally fall within both selective and additional licensing designations, but only one licence is normally required.

Frequently asked questions

What is additional licensing?

A scheme a council can introduce requiring licences for HMOs that fall outside the mandatory scheme, typically smaller shared houses.

How do I know if my area has a scheme?

Check the council's licensing pages, or use the RentDocs council licensing database, and re-check before each new tenancy as schemes run for fixed periods.
