What Is HMP Aylesbury Like?

Last reviewed: July 2026

Quick answer: HMP Aylesbury is a Category C men’s training prison in Buckinghamshire, holding around 370–400 adult men. It changed role in 2022: for many years it was a young offender institution for 18–21-year-olds serving long sentences, but it now operates as an adult training prison focused on work, education and rehabilitation. Recent inspections have flagged real challenges around safety and stability as the prison beds into its new role.

Aylesbury has a long and well-known history, so families are sometimes confused about what it is today. This guide explains its current role, what daily life involves, and how to visit and keep in touch.

Who Aylesbury holds now

Since October 2022, Aylesbury has operated as an adult male Category C training prison. Previously it was a high-profile young offender institution holding young men aged 18 to 21, often serving long or life sentences for serious offences. That change matters: if your relative is going there now, they will be among adult men in a training-prison regime, not among the under-21s the prison was historically known for.

What daily life is like

As a Category C training prison, Aylesbury is meant to focus on constructive activity: work, education, vocational training and offending-behaviour programmes, with association time for phones, showers and the gym. In practice, a prison changing role can go through an unsettled period, and inspectors have described Aylesbury facing significant challenges around safety, drugs and time out of cell during this transition. Regimes can therefore vary, and new arrivals may find the first weeks restrictive.

Safety and support

If you are worried about a relative’s wellbeing at Aylesbury, contact the prison and ask for the Safer Custody team, who can arrange support. Prisoners can speak to a trained Listener at any time, and can call the Samaritans free and in confidence from prison phones. Engagement with education and programmes is worth encouraging, as it supports both wellbeing and future progression.

Common misunderstandings

  • “Aylesbury is still a young offenders’ prison.” Not since 2022 — it is now an adult Category C training prison.
  • “Training prison means minimum security.” It is still a closed Category C prison with full security.
  • “I can post in clothes and treats.” Generally not — send money for the canteen. See what you can send.

Visiting and staying in touch

Visits must be booked in advance and you must be on the prisoner’s approved visitor list. You can also keep in touch by phone, letters and Email a Prisoner, and send credit through the official Send money to someone in prison service.

A note from experience

Our founder Daniel Hockey came through the prison system himself, from HMP Wandsworth to open conditions at HMP Ford. His steadying message to families of men arriving at a prison in transition like Aylesbury is that unsettled early weeks usually improve, and that regular contact and encouragement to engage with the regime make a real difference.
