The most recent HM Inspectorate of Prisons report says a new governor has brought focus to safety, supported by major investment in staff and training.
The Trinity unit now serves enhanced prisoners with violence, self-harm, and drug issues improving.
Inspectors say there’s still a long way to go, but progress is clear.
They noted there had been some improvement in staff experience and capability, with support and mentoring from experienced detached duty staff and the His Majesty’s Prison and Probation Service (HMPPS) standards coaching team.
After the last inspection, the latter team had delivered a high number of individual and group coaching sessions over a period of three months. These sessions covered issues such as the basic tasks of an officer and professional conduct.
Since January 2025, further HMPPS assistance had been provided by the Prison Performance Support Programme, which had a continued focus on upskilling staff and building capability.
