Nearly Half of Electronic Offender Tags Fitted Late, Watchdog Warns Victims Put at Risk

A new inspection report has found that almost half of the electronic tags used to monitor offenders in England and Wales are not being fitted on schedule, creating significant delays that watchdog officials say are placing victims at risk. The review, carried out by His Majesty's Inspectorate of Probation (HMIP), highlights serious shortcomings in the rollout of a technology that is central to the government's strategy for managing criminals in the community.

According to the findings, only 55% of GPS and radio frequency tags were installed on time. Alcohol monitoring tags performed slightly better, with 60% fitted promptly, but the overall picture remains one of widespread delays across the tagging system. In some instances, offenders waited more than two weeks for equipment to be fitted, while one in ten individuals waited up to five months after the required deadline had passed.

The consequences of these delays are not merely administrative. The report warns that late fitting leads to repeated breaches of court and prison orders, undermining the restrictions that tagging is meant to enforce. Electronic monitoring is used by the Probation Service to track curfews and other conditions imposed by courts or prison authorities, making timely installation essential to its purpose.

Martin Jones CBE, HM Chief Inspector of Probation, said the findings exposed a fundamental risk in how the technology is being deployed. He warned that electronic monitoring can create a false sense of assurance when the technology is not matched by effective professional practice. He also cautioned that expanding tagging programmes without first addressing their weaknesses risks overpromising and underdelivering on public protection.

The report also identified a range of reasons why tags are not fitted on time. In some cases, the individuals subject to tagging orders simply did not make themselves available for the fitting appointment, complicating efforts by probation staff to complete installations within the required window.

Victims' Commissioner Claire Waxman OBE said those affected by crime need to be informed immediately when tagging is delayed. She explained that a lack of timely information could give victims a false sense of security, leaving them unaware that restrictions they believe are in place have not yet taken effect. Waxman also called for a robust response when breaches occur, but acknowledged real concerns about whether overstretched probation services have the capacity to deliver one.

Beyond the delays in fitting, the inspection uncovered problems with how data generated by the tags is used. Information from the devices was frequently underused, with major violations raised and explored in only 46% of relevant cases. Inspectors also found little evidence that electronic monitoring was being applied consistently as a tool to promote behaviour change among offenders.

The report sets out three categories of tags currently in operation: curfew tags, location tags, and alcohol tags. All are intended to impose strict controls as part of an offender's punishment, while also managing risk, supporting safeguarding, and protecting victims. When an individual breaches their order, the consequences can include an immediate return to prison, a court order, or a formal warning.

As of June 2026, a total of 27,847 people in England and Wales were subject to tagging orders involving equipment. That figure is expected to rise substantially, with plans announced earlier this year to significantly expand electronic monitoring under the Sentencing Act 2026. The legislation aims to ease pressure on the prison system by managing more offenders in the community rather than behind bars.

Thousands more prisoners are due to be released early from October under the new law, and most of them will require tagging. The expansion means the volume of installations will increase at precisely the moment inspectors have identified systemic weaknesses in the fitting process, raising questions about whether the infrastructure and staffing exist to cope with the additional demand.

A Ministry of Justice spokesperson responded to the report by insisting that public protection remains the government's priority. They pointed to what they described as the biggest expansion of tagging in British history, backed by £100 million in funding, and noted that tag install rates have risen by nearly 50% since 2024. The spokesperson also cited a record £700 million investment in probation and community services, including the recruitment of 2,300 trainee officers over the last two years and a further 1,300 this year, which they said would ensure dangerous offenders are kept under closer surveillance than ever before.

The findings nonetheless raise difficult questions about the balance between expanding community-based punishments and ensuring they are properly enforced. Tagging is often presented as a cost-effective alternative to custody, capable of reducing reoffending while easing overcrowding in prisons. But the HMIP report suggests that without adequate staffing, timely installation, and consistent use of monitoring data, the scheme may fail to deliver the protection the public expects.

The report adds to a growing body of scrutiny around community sentencing. A separate review published in July found that thousands of offenders were not wearing electronic tags at all, while the probation chief inspector has previously warned that the early release scheme risks enabling more serious crimes. Together, these findings point to a system under strain, attempting to supervise a rapidly growing population of offenders with resources and processes that may not yet be fit for purpose.

For victims, the practical implications are stark. A tag that arrives months late, or data that is never properly reviewed, means restrictions exist on paper but not in practice. As the government presses ahead with its expansion plans, the inspectorate's message is clear: without fixing the weaknesses identified in this report, the promise of improved public protection through tagging may prove difficult to keep.
