Electronic alcohol monitoring has experienced dramatic growth across England and Wales, with 4,261 individuals fitted with alcohol monitoring devices as of 2nd June 2025. This represents a four-fold increase from three years ago when fewer than 1,000 people were subject to this form of electronic monitoring.

Two-Tier Monitoring System

The alcohol monitoring framework operates through two distinct mechanisms, each targeting different stages of the criminal justice process and varying levels of alcohol-related offending.

Alcohol Abstinence and Monitoring Requirement (AAMR)

AAMR represents the court-imposed element of alcohol monitoring, introduced in October 2020. This system imposes total alcohol abstinence for up to 120 days following sentencing for alcohol-related criminal behaviour. The device monitors alcohol consumption through sweat analysis, providing continuous surveillance of compliance.

Strict eligibility criteria limit AAMR use to adults (18 years or over) who are not alcohol dependent. Individuals already subject to an Alcohol Treatment Requirement (ATR) cannot receive AAMR, ensuring the two interventions don’t conflict. This targeting approach aims to address alcohol-related offending without interfering with clinical treatment for alcohol dependency.

Alcohol Monitoring on Licence (AML)

AML operates as an additional licence condition for offenders released from custody whose offending and risk profiles are alcohol-related. This system offers greater flexibility than AAMR, providing two licence condition options: total abstinence from alcohol, or compliance with requirements specified by probation practitioners to address alcohol needs while restricting alcohol use.

This graduated approach allows probation services to tailor monitoring to individual risk profiles and treatment needs, potentially supporting longer-term behaviour change rather than simple prohibition.

Technology and Compliance

The monitoring technology demonstrates high reliability rates. From AAMR’s introduction in October 2020 through to 6th June 2025, devices recorded no tamper or alcohol alerts for 97.3% of days worn. This compliance rate suggests either effective deterrent effects or successful targeting of appropriate individuals.

The technology monitors alcohol consumption through transdermal alcohol detection, measuring alcohol metabolites in sweat. This method provides continuous monitoring without requiring active participation from the individual, distinguishing it from breathalyser-based systems that rely on scheduled testing.

Broader Electronic Monitoring Context

Alcohol monitoring operates within a larger electronic monitoring framework encompassing 23,977 individuals as of 2nd June 2025. Within this total population:

• Location Monitoring (GPS) devices account for 51% (12,318 individuals)
• Curfew (RF) devices account for 34% (8,125 individuals)
• Alcohol Monitoring (AM) devices account for 18% (4,261 individuals)

The alcohol monitoring component has grown disproportionately compared to other forms of electronic monitoring, reflecting both expanded court usage and increased licence conditions for alcohol-related offenders.

Order Type Distribution

The 23,977 people subject to electronic monitoring are distributed across different order types:

• Post-release orders: 8,327 individuals (35%)
• Court bail orders: 8,134 individuals (34%)
• Immigration orders: 3,994 individuals (17%)
• Court sentences: 3,427 individuals (14%)

While specific breakdowns for alcohol monitoring by order type aren’t provided in the latest data, the overall distribution suggests significant use across different stages of the criminal justice process.

Policy and Implementation Challenges

The rapid expansion of alcohol monitoring raises questions about capacity, targeting, and effectiveness. The four-fold increase over three years indicates either growing recognition of alcohol’s role in offending or expanding policy preference for technological supervision over traditional approaches.

Data quality issues have affected monitoring statistics following the transition from Capita to Serco service delivery in May 2024. Some individuals appeared in both systems during the transition, complicating trend analysis and highlighting implementation challenges in large-scale monitoring programmes.

Criminal Justice Integration

Alcohol monitoring integrates with broader criminal justice interventions, potentially complementing rather than replacing traditional approaches. The distinction between AAMR for non-dependent offenders and ATR for those requiring clinical intervention suggests recognition of alcohol problems’ complexity.

The high compliance rates may reflect effective screening processes that identify suitable candidates, though they could also indicate that some alcohol-related offending occurs among people who can successfully abstain when monitored, rather than those with severe alcohol use disorders.

Resource Implications

The expansion from fewer than 1,000 to 4,261 monitored individuals represents significant resource investment in monitoring infrastructure, staff training, and system maintenance. The transition between service providers demonstrates the operational complexity of managing large-scale electronic monitoring programmes.

Probation services must develop expertise in using alcohol monitoring data for case management decisions, particularly regarding licence compliance and risk assessment. This integration requires training and system development beyond the technology itself.

Future Trajectory

Current government commitments to substantially expand electronic monitoring suggest continued growth in alcohol monitoring usage. The four-fold increase over three years may represent early adoption rather than mature programme implementation.

Trend analysis remains challenging due to system transition issues, but the overall direction appears firmly upward. The 97.3% compliance rate may encourage further expansion, though this assumes current targeting approaches continue to identify suitable candidates.

Evaluation and Evidence

The expansion occurs without comprehensive public evaluation of alcohol monitoring effectiveness in reducing reoffending or supporting behaviour change. The high compliance rates indicate successful monitoring but don’t demonstrate crime reduction or long-term abstinence following monitoring periods.

Research comparing alcohol monitoring with alternative interventions could inform optimal targeting and integration with treatment services. The distinction between surveillance and support becomes particularly relevant for alcohol-related offending, where underlying addiction issues may require clinical intervention.

Conclusion

The dramatic expansion of alcohol monitoring from fewer than 1,000 to 4,261 individuals represents a significant shift in criminal justice responses to alcohol-related offending. High compliance rates suggest effective implementation, though questions remain about long-term effectiveness and optimal integration with treatment services.

The growth trajectory appears likely to continue given policy commitments to electronic monitoring expansion. However, the lack of comprehensive evaluation data limits understanding of whether technological surveillance translates into meaningful reductions in alcohol-related crime or improved outcomes for monitored individuals.
