We are an independent inspectorate reporting on the treatment and conditions for those in prison and other types of custody in England and Wales.
All inspections are conducted against our published inspection criteria. Most are unannounced.

Coordinated by HMI Prisons, the UK’s NPM is made up of 21 organisations which monitor places of detention to help prevent torture and ill-treatment.
