Class C2A

Class C2ASecure Residential Institutions

Class C2A covers secure residential institutions where individuals are detained — primarily prisons, young offender institutions, immigration removal centres, and secure psychiatric hospitals. It was created as a distinct use class to reflect the very different planning, security, and community considerations that apply compared to ordinary residential institutions (C2). New C2A facilities are typically major applications requiring detailed assessment.
