Electronic Tag Fitting Delays Leave Victims Exposed, Probation Watchdog Warns

Nearly half of all electronic monitoring tags intended to track offenders in England and Wales are not being fitted within required timeframes, according to a damning new report from His Majesty's Inspectorate of Probation (HMIP). The findings suggest that chronic delays in the tagging system are undermining public protection and leaving victims exposed to further harm.

The inspectorate's review found that only 55% of GPS and radio frequency tags were installed on schedule, while the figure for alcohol monitoring tags stood at just 60%. In some instances, offenders waited more than two weeks for equipment to be fitted, and approximately one in ten individuals experienced delays stretching to five months beyond the required deadline.

Martin Jones CBE, HM Chief Inspector of Probation, said the gap between the promise of electronic monitoring and its actual delivery posed a serious risk. He warned that tagging could create "a false sense of assurance" when the technology is not supported by effective professional practice. He further cautioned that expanding tagging programmes without first addressing their existing weaknesses risks "overpromising and underdelivering on public protection."

The report highlights that delays have contributed to repeated breaches of court and prison orders, with some offenders effectively unmonitored during the periods when they should have been subject to strict controls. Among the reasons cited for late fittings was that some individuals simply failed to make themselves available for appointments, though inspectors indicated this was not the sole factor behind the backlog.

As of June 2026, a total of 27,847 people in England and Wales were subject to tagging orders with equipment. Electronic monitoring is used by the Probation Service to enforce curfews and other conditions attached to court or prison orders. The technology is intended to support punishment, risk management, safeguarding and the protection of victims.

The report also raised concerns about how data generated by the tags is being used. Inspectors found that information from the devices was frequently underused, with major violations raised and properly investigated in only 46% of relevant cases. Additionally, there was little evidence that electronic monitoring was being applied consistently to encourage behaviour change among offenders.

Victims' Commissioner Claire Waxman OBE said victims must be informed "immediately" if tagging is delayed, arguing that silence on the issue can foster a "false sense of security" among those relying on the system for protection. She called for a "robust response" when breaches occur but expressed "real concerns" about whether overstretched probation services are equipped to deliver one.

There are three main categories of tags currently in use: curfew tags, which monitor whether an offender remains at a specified address during set hours; location tags, which use GPS technology to track movements; and alcohol tags, which detect consumption by monitoring perspiration. Those who breach their orders may be returned to prison immediately, given a court order, or issued a formal warning.

A Ministry of Justice spokesperson responded to the findings by stating that public protection remains the government's priority. They pointed to what they described as the "biggest expansion of tagging in British history," supported by £100 million in funding, and noted that tag installation rates have risen by nearly 50% since 2024. The spokesperson also highlighted a record £700 million investment in probation and community services, alongside the recruitment of 2,300 trainee officers over the past two years and a further 1,300 planned for this year.

The inspectorate's findings come amid a broader push to expand electronic monitoring across the justice system. Plans announced earlier this year under the Sentencing Act 2026 aim to ease pressure on prisons by managing more offenders in the community rather than behind bars. As part of that law, thousands more prisoners are due to be released early from October, with most expected to require tagging.

The intersection of these two developments—a system already struggling to fit tags on time and a looming influx of newly released offenders requiring monitoring—has raised concerns about whether the infrastructure can cope. The report's authors suggest that without significant operational improvements, the expansion could strain services further and dilute the protective value of tagging.

The HMIP report adds to a growing body of scrutiny over community-based sentencing measures. While electronic monitoring is widely viewed as a cost-effective alternative to custody, its effectiveness depends heavily on timely installation, consistent data monitoring, and swift responses to breaches. The inspectorate's findings suggest that all three elements are currently falling short.

For victims and the wider public, the implications are stark. A tag that arrives months late, or whose data is not acted upon, offers little real protection. The report calls into question whether the current system can deliver the assurances that courts, victims and the public expect when tagging orders are issued.

The Ministry of Justice maintains that its investment and recruitment plans will address the shortcomings identified. However, the inspectorate's warning that expansion without reform risks "overpromising and underdelivering" suggests that unless the operational gaps are closed, the government's ambitious tagging agenda may struggle to meet its stated goals of public protection and reduced prison pressure.
