Question to the Ministry of Justice:

To ask the Secretary of State for Justice, what was the rate of compliance for people fitted with an alcohol monitoring device after their release from prison, in each year since 2021.

We are unable to provide compliance rates by year for those released from custody and subject to alcohol monitoring. However, our published research for this cohort has shown around four out of five prison leavers with an alcohol monitoring condition added to their licence during 2023 did not violate their order. Of those who did violate their order, most only received a single violation. The Department’s published research can be found here - AML: Process and Interim Impact Evaluation.

The compliance rate of alcohol monitoring imposed by the court as part of a Community Order or Suspended Sentence Order, which imposes a total ban on drinking alcohol for up to 120 days, showed from the introduction of the technology in October 2020 through to 6 June 2025, the devices did not register a tamper or alcohol alert for 97.3% of the days worn. Anyone who does break the rules, risks being returned to custody.
