Our eyes on the inside, a voice on the outside

Monitoring fair and humane treatment

Independent Monitoring Boards are made up of over a thousand unpaid volunteers operating in every prison in England and Wales, and every immigration detention facility across the UK.

IMB members are the eyes and ears of the public, appointed by ministers to perform a vital task: independent monitoring of prisons and immigration detention. They report on whether the individuals held there are being treated fairly and humanely and whether prisoners are being given the support they need to turn their lives around. This can make a huge difference to the lives of those held within these facilities.

Virtual information event

Hear from current volunteers at our next virtual event – 29 January 2025, 5-6:00pm (prisons).

Our virtual open evenings are a great opportunity to hear directly from IMB members.

You will have the chance to hear members talk about their experiences, ask questions and learn more about what the role consists of from those who are currently volunteering.
