Welcome to HMI Prisons.

We help to make sure that detention in the UK is humane, decent and prepares people for returning to society.


Desperate times for prisons

Against the backdrop of the growing prison population crisis, the 2023-24 annual report of HM Chief Inspector of Prisons paints a devastating picture of what is happening inside our jails.



The inability of national leaders to reform the youth justice system as the population has fallen has resulted in a youth custodial estate which has been arrived at by adaptation of an existing unsatisfactory estate rather than by design. Having a small number of youth custodial establishments also means that most children are now accommodated further from home, increasing journey times to and from court, making it harder for them to see friends and family and undermining efforts at resettlement.
Angus Jones, HMI Prisons Team Leader for Children and Young People
The key to [Drake Hall’s] success was an excellent range of support, care and interventions. The impact of this was twofold; it not only helped women to cope with life inside, but improved their chances of a successful release. Most women we meet in prison have experienced significant trauma and Drake Hall was providing excellent support to help them deal with this. Bereaved women could get talking therapy to manage their grief, while others who had suffered violence perpetrated by men (all too common unfortunately) could access counselling.
Jonathan Tickner, Inspector

Improving behaviour in prisons

These are challenging times for prisons, but some have created cultures that encourage prisoners to take part in employment and education that should help them to secure employment on their release.
