Latest inspection
At its last full inspection (February 2026; report published May 2026), inspectors found outcomes for prisoners were not sufficiently good for purposeful activity and preparation for release; reasonably good for safety and respect. It held 370 people at the time, against an operational capacity of 402.
Healthy prison tests: inspectors grade four areas from 1 (poor) to 4 (good).

The Phoenix Unit will house 49 men, 15 of them serving IPP sentences, and offer yoga, acupuncture and a Stoicism course to help disengaged prisoners move towards parole.
Inspectors upgraded safety and respect at the category C training prison to reasonably good. They found high drug use, rising self-harm and weak education and sentence planning.
A report published in March 2023 found that purposeful activity at the prison had fallen to poor, with many men locked up for 23 hours a day after a sudden switch to category C.
A report published in February 2020 found safety at HMYOI Aylesbury had improved from poor, after the population was halved, but warned that risk assessment for its high-risk young men was failing.
