HMP Millsike - Case Admin

Mitie Care & Custody (C&C) is driven by a bold vision: to establish HMP Millsike as a place of restoration and rehabilitation, where prisoners can unlock their full potential and make meaningful, positive changes in their lives. Our mission is clear: to create an environment that empowers, inspires, and supports individuals to re-enter society with hope, purpose, and a life plan. To achieve this, we will set a culture of rehabilitation and restoration underpinned by integrity and high expectations.

This role is based within the Offender Management Unit (OMU) at HMP Millsike. The OMU is responsible for all aspects of a prisoner's ‘case', dealing with issues such as risk management, parole applications and sentence planning. As a case administrator, you will be contributing directly to the primary function of HMP Millsike – that of the rehabilitation of its prisoners. You will be responsible for providing administrative support within the OMU, working alongside both probation and prison colleagues.

The OMU is a fast-paced department that responds to and liaises with both internal and external agencies such as local courts, police and probation. There are many different aspects of the role which will lead to continued learning and training. The role will largely be administrative and based within the OMU Hub but there may be a need for occasional contact with prisoners and officers regarding the issuing of paperwork. Any mandatory training required will be given to successful applicants so a willingness to complete training is necessary.

The role is primarily administrative, but the unique environment of the prison offers numerous opportunities for engaging work and a variety of tasks. You will be responsible for undertaking any transactional or administrative activities related to the Offender Management Unit and the broader goal of reducing reoffending. This includes processes such as the Offender Assessment System (OASys), arranging Release on Temporary Licence (RoTL), handling bail and BASS applications, and managing Multi‑Agency Public Protection Arrangements (MAPPA). Additionally, you will be involved in the re‑categorization of prisoners, sentence calculations, recall paperwork, public protection matters, and documentation related to the transfer and release of prisoners, including organising resettlement boards and processing parole applications. Maintaining accurate records and data in accordance with established standards and policies is essential.

All administrative functions must align with the Offender Management in Custody Model, relevant policy frameworks, and Prison Service instructions. You will receive support to understand how your role connects to these policies, including any time‑related expectations, through ongoing learning, training, and supervision from line management.

The ideal candidate will possess intermediate IT skills, including proficiency in Microsoft Excel, Word, and Outlook, along with some experience in updating central data systems. Clear written communication is essential, ensuring that all correspondence meets customer expectations. Key skills and attributes include strong verbal and written communication abilities, a positive problem‑solving approach, and excellent organisational skills. The candidate should be able to work efficiently at a fast pace and demonstrate a willingness to engage in continuous learning and complete necessary training. Adaptability is important, as the role requires the ability to manage change and adjust working practices in response to legislative and procedural updates. Additionally, the candidate should be capable of working effectively as part of a team.

As a business, Mitie Care & Custody is committed to diversity and inclusion and we would welcome applications from a wide range of backgrounds including veterans, those looking for a career change, and people who have experience in social care or a learning environment. Full training will be given where applicable, and we would encourage anyone who might be thinking about a role in a secure establishment to get in touch.
