Additional licensing: yes, not stated on fetched page (council search snippet describes it as a city wide scheme).
Selective licensing: could not be verified from the council page.
What an Article 4 direction means
HMO Article 4 directions remove the permitted-development right to convert a family home (C3) to a small HMO (C4, 3 to 6 people). Inside one, that conversion needs full planning permission. Councils may also run additional licensing (smaller HMOs) or selective licensing (all private rentals) in designated areas. Planning permission and licensing are separate: a licence does not grant planning permission, and permission does not remove the need for a licence.
