While the concept of co-production is becoming embedded in mental health and social care, the criminal justice system (CJS) has been slower in embracing this approach. In this article, we draw on the findings of a process evaluation of the Include UK Hub – a co-produced service for people with offending histories in Swansea, UK and, in doing so, introduce the DEVICES principles of co-production. The DEVICES is derived from the empirical evaluation data and includes the following principles – Development, Empathy, Voices, Individual, Change, Empowerment, and Spaces. These principles will appeal globally to practitioners and policymakers looking to meaningfully utilise co-production to develop services and support for people in the criminal justice system.
