Question to the Ministry of Justice:

To ask the Secretary of State for Justice, with reference to his Department's research entitled Alcohol monitoring on licence: process and interim impact evaluation, published 30 October 2025, what assessment his Department have made of the adequacy of alcohol monitoring readings from people on Alcohol Monitoring Licence orders whose tags were later removed due to potentially incorrect fittings.

Alcohol monitoring on licence was introduced in Wales in 2021 and England in 2022 and enables probation to include an additional licence condition banning or restricting the consumption of alcohol, where a criminogenic need related to alcohol misuse is identified as an increase to risk. The alcohol monitoring on licence: process and interim impact evaluation was published on 30 October 2025: https://www.gov.uk/government/publications/alcohol-monitoring-on-licence-process-and-interim-impact-evaluation. A further impact evaluation exploring reoffending will be published in due course which will measure longer-term outcomes than the existing published evaluation. The sample size is not confirmed but we expect it to be broadly similar.

The process and interim impact evaluation of Alcohol Monitoring on Licence scheme was based on a sample of the overall tagged population. The process evaluation reported some instances where tag wearers experienced pain or discomfort and had the tag changed or removed. These issues did not indicate widespread concerns about the reliability of alcohol tag readings.
