NAO Exposes 8,900 Untagged Offenders as Early Releases Loom

NAO Report Lays Bare Systemic Failures in Electronic Monitoring

The National Audit Office has delivered a withering assessment of the electronic tagging system in England and Wales, revealing that 8,900 offenders who should be wearing tags are not being monitored at all. As of March 2026, 28,700 people were tagged, yet 24% of those required to be under surveillance remain unaccounted for in any meaningful way. This damning verdict arrives precisely as the Ministry of Justice prepares to unleash thousands of early releases under the Sentencing Act 2026, a measure designed to create 7,000+ prison places from September.

The timing could scarcely be more alarming. Probation officers across London, the North East and Greater Manchester already warn that dangerous individuals are slipping through the cracks. The report does not mince words: the system is simply not working effectively, creating risks to public protection, according to NAO chief Gareth Davies.

Disputed Figures Fuel Growing Distrust Between NAO and Ministry of Justice

The Ministry of Justice disputes the NAO’s headline figure of 8,900 cases, insisting the true number stands at 5,450. Yet even this lower estimate represents a substantial failure of oversight. The Public Accounts Committee, chaired by Sir Geoffrey Clifton-Brown, has already signalled that it intends to summon senior officials to explain how such a discrepancy could arise in the first place.

Regional variations compound the problem. In Wales and the South West, rural tag-fitting teams struggle with long travel times, while London probation caseloads have ballooned beyond sustainable levels. North East victims groups have voiced particular fury that monitoring gaps persist even for those convicted of the most serious offences.

Serco’s Mixed Performance Highlights Operational Weaknesses

Private contractor Serco runs the tagging system under HMPPS oversight. While it met 95% of timeliness targets, it succeeded in fitting tags on only 62% of people visited. The backlog of outstanding visits peaked at 7,000 in October 2024 and has proved stubbornly resistant to clearance. These are not abstract statistics; they represent real individuals who courts ordered to be monitored yet who remain free of any electronic restraint.

Three distinct tag types exist: curfew, location monitoring and alcohol abstinence. Each requires precise fitting and ongoing supervision. When fitting rates fall to 62%, the entire architecture of community punishment begins to crumble.

Probation Staffing Crisis Leaves Officers Overwhelmed

A probation staff shortfall of 2,200 as of March 2026 has left frontline officers struggling to manage even basic caseloads. In Greater Manchester and the West Midlands, experienced staff report that they can no longer guarantee the level of scrutiny required when offenders are released early. The government has promised £700m for probation reform, yet recruitment and retention remain chronically poor.

One senior officer in London told Channel 4 News that the combination of early releases and tagging failures creates a perfect storm. “We are being asked to do the impossible with fewer people every month,” she said.

Government Expansion Plans Carry Clear Public Safety Risks

Ministers have allocated £100m for electronic monitoring improvements and a further £175m for expansion between 2026 and 2029. From 2027, an estimated 22,000 more people per year will require tagging. Sir Geoffrey Clifton-Brown has warned bluntly that this rapid scaling “risks wasting public money and puts public safety at risk”.

Pia Sinha, chief executive of the Prison Reform Trust, cautions against viewing electronic monitoring as a panacea. “Technology can support supervision,” she notes, “but it cannot replace skilled probation officers who understand risk and can intervene before harm occurs.”

Victims’ Voices Reveal the Human Cost of Monitoring Failures

Jackie Long of Channel 4 News spoke to Carol, whose father received a 20-year sentence for raping her as a child. Carol’s experience underscores why robust monitoring matters. When tags fail or are never fitted, victims lose the fragile sense of security that the justice system promises. Similar stories echo across the North East, where victims groups have organised public meetings to demand accountability from HMPPS.

The Sentencing Act 2026 will see serious violent and sexual offenders among those released early. Without a functioning tagging system, the already stretched probation service faces an impossible task. The NAO report makes clear that current arrangements offer no reliable safeguard.

Urgent Questions for Ministers as Public Protection Hangs in the Balance

The convergence of early releases, chronic staffing shortages and a demonstrably unreliable tagging regime demands immediate ministerial attention. Gareth Davies’s conclusion that the system is “not working effectively” is not political rhetoric; it is the measured finding of the National Audit Office. With 8,900 cases already under review by HMPPS and a further surge in demand expected from 2027, the window for corrective action is narrowing rapidly.

Regional probation services in London, Wales and the North East are already signalling that they cannot absorb additional risk without substantial extra resources. The government’s £100m investment and £175m expansion fund may prove insufficient if the underlying operational failures identified by the NAO remain unaddressed. Public safety cannot be assured by technology that fits only 62% of those visited or by a system that leaves 24% of required cases unmonitored.
