Statistician’s comment
Between 31 December 2022 and 31 December 2023 the number of individuals fitted with an electronic monitoring device increased. This has been driven by the increased use of GPS tags, particularly for the immigration cohort, and AM tags, particularly for the post release cohort, despite the continued decrease in the use of RF tags.
Court bail orders remain the largest cohort of individuals fitted with an electronic monitoring device, accounting for 35% (6,901) of the 31 December 2023 caseload. The use of electronic monitoring for those on court bail increased sharply in early 2020 in response to the covid pandemic’s impact on the courts, reaching a peak in March 2021. Although numbers declined a little before stabilising, from June 2022 the numbers again increased and are now at record levels.
In the year ending 31 December 2023 there were 57,463 new order notifications, a 5% increase compared to the year ending 31 December 2022. In the same period there were 54,013 completed orders, a 5% increase on the previous period.

Background
Electronic monitoring supports the police, courts, probation, prisons and the wider justice system in England and Wales. It is a way of remotely monitoring and recording information on an individual’s whereabouts or movements and alcohol consumption, using an electronic tag which is normally fitted to a subject’s ankle. Information about the compliance with an individual’s order is monitored. Electronic monitoring may be used:
-
as a condition of court bail;
-
as a requirement of a court sentence, primarily community orders and suspended sentence orders;
-
for Home Detention Curfew;
-
as a licence condition following release from custody;
-
as a condition of immigration bail, managed by the Home Office; or
-
to intensively monitor a small number of individuals including: some of the highest risk offenders managed under Multi-Agency Public Protection Arrangements (MAPPA); those granted bail by the Special Immigration Appeals Commission (SIAC); and those made subject to Terrorism Prevention and Investigation Measures (TPIMs).
Electronic monitoring was first introduced in 1999 to monitor compliance with curfews using radio frequency tags, where curfew is the only requirement these continue to be used. The service was expanded from November 2018 to introduce satellite enabled location monitoring tags. The tags use GPS technology which can record an individual’s movements 24 hours a day. Roll out was fully completed in March 2021 when the provision of GPS monitoring was extended to under 18s.
GPS tags provide additional functionality, allowing the monitoring of:
-
compliance with exclusion zones;
-
attendance at a required activity or appointment;
-
an offender’s whereabouts (trail monitoring);
-
multiple conditions or requirements if necessary, such as a combination of exclusion zones, curfew, monitored attendance and trail monitoring.
Since 2021 HMPPS has expanded the use of GPS tags for the following offender cohorts:
-
acquisitive crime: From April 2021 they have been used as a licence condition for some adult offenders convicted of a specified acquisitive crime as their principal offence and who have received a custodial sentence of 12 months or more and been released on licence. In late October 2022 this was expanded to those who had received a custodial sentence of 90 days or more. This is currently being piloted in 19 police force areas.
-
several small pilots for specific offender cohorts, such as Licence Variation, GPS Youth Rehabilitation, and Domestic Abuse Perpetrators on Licence.
-
immigration expansion: The Immigration Act 2016 introduced a duty on the Home Office Secretary of State to impose an electronic monitoring condition on Foreign National Offenders and other non-UK citizens subject to deportation proceedings. Following this, in August 2021, HMPPS began using GPS monitoring for those individuals who had been released from Prisons or Immigration Detention under ‘Immigration Bail’ on behalf of the Home Office. From 31 August 2022 this was extended to Scotland and Northern Ireland in December 2022. The Home Office also commenced a pilot in June 2022 to impose an electronic monitoring condition of immigration bail to non-foreign national offenders (FNO) asylum claimants who arrive in the UK via unnecessary and dangerous routes. This pilot concluded in December 2023.
Electronic monitoring using a non-fitted device was introduced in November 2022 for the immigration cohort. These devices utilise periodic biometric verification as an alternative to using fitted devices. Those with a non-fitted device have been included within the GPS cohort for the purposes of this analysis.
Alcohol monitoring was introduced to courts in Wales in October 2020 and expanded to courts in England on 31 March 2021 to support the new community sentencing option, the Alcohol Abstinence and Monitoring Requirement (AAMR). An AAMR may only be used when sentencing for alcohol-related criminal behaviour and it imposes a total ban on drinking alcohol for up to 120 days. Compliance with the ban is monitored electronically using an alcohol tag which continuously monitors for the consumption of alcohol via an offenders’ sweat.
An AAMR order may be imposed by the court as part of a community order or suspended sentence order where:
-
the offence, or associated offence, for which the requirement is being imposed, is alcohol-related;
-
the subject is not alcohol dependent or has an Alcohol Treatment Requirement (ATR) recommended or in place; and
-
the subject is an adult (18 years or over)
For offenders being released from custody whose offending and risk is alcohol related, an Alcohol Monitoring on Licence (AML) additional licence condition was introduced in Wales in November 2021 and rolled out in England in June 2022. There are two licence conditions available for AML:
-
requires total abstinence from alcohol, or
-
requires the offender to comply with requirements specified by their Probation Practitioner to address their alcohol needs, this will include restricting alcohol use.
1. Overall Summary
An individual may be given several orders at the same time and/or over the course of a year, therefore there will be more active orders at any one time than there are people being monitored. If an individual has multiple orders, when looking at order notifications each will be counted separately. However, when counting individuals, the subject will be included in a order cohort once according to a defined formula. Please see the technical note for more details.
Between 31 December 2022 and 31 December 2023 the total number of individuals fitted with an electronic monitoring device (a radio frequency, location monitoring device or alcohol monitoring device) increased from 16,602 people to 19,878, an increase of 20%.

However, the trend in the overall number of individuals fitted with an electronic device differs considerably by type of order:
-
court bail orders make up the largest proportion (35%) of electronically monitored individuals. At 31 December 2023, 6,901 individuals had court bail as their primary order type, up by 12% on the previous year. The use of electronic monitoring for those on court bail increased sharply in early 2020. Although numbers declined during 2021, from mid-2022 the numbers have again been increasing.
-
post-release orders were the second largest group with 5,242 individuals (26% of the caseload), up by 33% when compared with the previous year. This increase is mainly due to the increased use of alcohol monitoring for this group.
-
immigration orders were the third largest group with 4,360 individuals (22% of the caseload), up by 40% when compared with the previous year. The number of individuals in this cohort has steadily increased from August 2021 owing to the expansion projects.
-
court sentences (community orders and suspended sentence orders) were the fourth largest group with 3,307 individuals (17% of the caseload), down by 1% on the same point in the previous year. The numbers recovered following a sharp decline in early 2020 as a result of pressure on courts from the covid pandemic, the numbers again declined in mid-2022. This decrease began from April 2022 and is likely to be associated with mandating domestic abuse and safeguarding checks in all cases where electronic monitored curfews are proposed, which was introduced from April 2022 as can be seen by the decrease in those with a primary order type of community sentence with an RF tag.

2. Radio Frequency Monitoring
Between 31 December 2022 and 31 December 2023 the total number of individuals fitted with an electronic monitoring device and whose primary order was a RF order decreased from 8,290 individuals to 7,721, a decrease of 7%. Over the same period the proportion of individuals whose primary order was a RF order decreased from 50% to 39%.
-
court bail RF orders make up the largest proportion (53%) of RF monitored individuals. At 31 December 2023, 4,115 individuals had RF court bail as their primary order type, a decrease of 8% on the previous year. The use of electronic monitoring for those on RF court bail increased sharply in early 2020 in response to the covid pandemic’s impact on the courts.
-
post-release RF orders were the second largest group with 2,071 individuals (27% of the RF caseload), up by 11% when compared with the previous year.
-
court sentence RF orders (community orders and suspended sentence orders) were the third largest group with 1,535 individuals (20% of the caseload), down by 22% when compared with the previous year. The decline from April 2022 is likely to be associated with mandating domestic abuse and safeguarding checks in all cases where electronic monitored curfews are proposed is continuing.
-
as at 31 December 2023, there are no individuals that had immigration RF orders as their primary order type. HOIE have primarily used GPS tags since 2021 which has significantly reduced the numbers of RF devices used.

3. Location (GPS) Monitoring
Between 31 December 2022 and 31 December 2023 the number of individuals fitted with an electronic monitoring device and whose primary order was a GPS order increased from 6,533 individuals to 9,562, an increase of 46%. Over the same period the proportion of individuals whose primary order was a GPS order increased from 39% to 48%. As at 31 December 2023 GPS immigration bail accounted for 46% of all individuals whose primary order was a GPS order.
There were 2,161 new acquisitive crime orders imposed across England and Wales in the year ending 31 December 2023. Overall, 4,726 new acquisitive crime orders have been imposed since they were introduced.

4. Alcohol Monitoring
Between 31 December 2022 and 31 December 2023 the total number of individuals fitted with an alcohol monitoring device increased from 1,863 individuals to 2,832, an increase of 52%.
There were 11,413 new alcohol monitoring orders imposed across England and Wales in the year ending 31 December 2023. Overall 20,546 new alcohol monitoring orders have been imposed since their introduction.
Of the alcohol tags in use to monitor alcohol abstinence and monitoring requirements (AAMR) over the last quarter, between September 2023 and December 2023, the tags did not register a tamper or alcohol alert for 97.6% of the days worn. Since their introduction in October 2020, the tags did not register a tamper or alcohol alert for 97.3% of the days worn.
