Can a digital justice system ease prison overcrowding?

With the Sentencing Act nearing full implementation, the government is increasingly turning to electronic monitoring and community sentencing as part of its response to Britain’s prison overcrowding crisis. Aarav Tanguturi examines whether the technology is capable of delivering public safety and what this shift could mean for the private sector.

Amid tight fiscal constraints and severe overcrowding, the UK’s prison system is approaching breaking point. The long-term outlook is equally bleak, with projections showing that by early 2028 we will face a deficit of 9,500 prison places. Westminster faces an uncomfortable reality: new prisons cannot be built quickly enough to keep pace with demand. 

Political backlash

Pressure is mounting on Andy Burnham as he attempts to navigate the political consequences of the Sentencing Act 2026, following intense public backlash at the proposed early release of certain offenders. The controversy intensified when it emerged that the two killers of PC Andrew Harper were set to be released early under the existing regulations. 

The government therefore faces a difficult policy trade-off. Restoring public trust in the justice system appears to require scrapping the Sentencing Act. Yet abandoning the legislation would risk a failure to alleviate the overcrowding issue in our prisons.  

The reoffending trap

Even if early release schemes initially appear to relieve immediate pressure, reoffending continues to place significant pressure  on the system. Ministry of Justice statistics reveal that the reoffending rate in the UK stands at 28.9% and for sentences under a year this figure surges to 66%. By comparison, Norway is frequently cited for having one of the lowest reoffending rates globally, sitting at only 20%. The contrast highlights two fundamentally different attitudes to punishment embraced by each country. Chief Inspector of Probation Martin Jones warned that unless reoffending is tackled, a persistently high reoffending rate could undermine any effectiveness created by the scheme. 

Yet, beneath the controversy over which offenders should leave prison, it raises the question, where exactly will their sentence continue?

The rise of community sentencing

Should the Sentencing Act be fully implemented this October, we would expect to see Britain begin an operational shift with a greater proportion of sentencing moving away from physical prison cells and towards electronic monitoring.

Reports estimate that as many as 22,000 would be electronically tagged each year from 2027 onwards. The government has backed this transition, allocating up to £175 million between 2026 and 2029 to expand electronic monitoring and develop new approaches to technology.

In other words, technology under this model will no longer be an accessory to the justice system and instead is becoming integral to the prison infrastructure. The future might hold a virtual prison estate. 

But is the technology working?

Despite substantial government investment, performance since 2021 has  revealed operational flaws and inefficiencies in the system. The initial wave of monitoring technology created by one of the government’s external contractors was frequently subject to malfunctions.

The National Audit Office has stated that the monitoring technology developed by the Ministry of Justice is not working as intended. Its July 2026 report found that 8,900 reviewed cases, 24% of individuals tagged, were left unmonitored. The report also identified that there was severe understaffing of probation officers, with the new legislation only worsening the situation. The first wave of offenders under the current early release scheme are set to be released in October, increasing the already huge pressure on probation staff and placing further strain on an already under-resourced system. HMPPS found that there was an estimated 2,220 shortfall of probation officers in March 2026. Consequently, the National Association of Probation Officers is threatening strike action.

Ultimately this raises the question of whether electronic monitoring without integrated support can truly deliver public safety.

Where does the private sector fit in?

The justice system’s evolution is creating a significant and expanding commercial market between the private sector and the state.

In previous efforts to tackle reoffending, the government has contracted firms such as Novus to deliver digital literacy training in prisons aiming to rehabilitate offenders and help them reintegrate them into society. The relevance of this lies in a government study, which as of 2019 found that 82% of jobs require a certain level of digital skills. 

Meanwhile, the commercial reality of the ‘virtual prison’ is opening up a growing technology-driven market for software developers. NEC Software Solutions even acquired specialist firm Meganexus at the beginning of 2026, together providing offender management platforms that directly link prison records with live probation tracking. Specifically, these platforms can create a bridge between prison and probation, ensuring that when an offender is released, the rehabilitation progress that began in custody is not lost. It provides probation officers with the tools to log community service hours, rehabilitation milestones and monitor compliance. 

The expansion of community sentencing requires the government to contract not only hardware providers for electronic tagging but also software firms supplying the digital infrastructure around the justice system.

Going forward

It is clear the government will increasingly rely on technology to ease the prison overcrowding crisis, and that the existing monitoring systems are not working as intended.

If technology is to become a central pillar of Britain’s justice system, the government must demonstrate to the public, more importantly victims, that it has a robust and reliable system in place for monitoring offenders and one that does not risk public protection.
