For centuries, the security of prisoners was a matter of state. The police, the courts, and the prison service itself managed custody, transport, and detention.
Accountability was direct and failures were political, not contractual. But from the 1980s onwards, a quiet revolution began. Governments in the UK and USA opened the gates to private contractors, promising efficiency and savings. What followed was a wave of outsourcing that turned incarceration into a business—and controversy into a constant companion.
From State Control to Private Contracts
1980s-1990s Policy Change: Under Margaret Thatcher, there was a push to introduce competition into public services. The idea was that private firms could deliver services more cheaply and efficiently.
Before 1992: All UK prisons were state-run. Prisoner transport was handled by police and prison officers. Immigration detention was managed by the Home Office.
1992
The UK's first private prison, HMP Wolds, opened under G4S. This marked the start of private involvement in custody.
1990s - 2000s
Outsourcing expanded rapidly. Serco, G4S, Sodexo, and GEOAmey began running prisons, escort services, and immigration centres.
Today
Around 14 prisons in England and Wales (17% of the prison population) and two in Scotland (16.5% of prisoners) are privately operated.
In the USA, the story was similar. The 1980s saw the rise of CoreCivic and GEO Group, two giants of private prisons. By the 2000s, both were major suppliers to ICE, running immigration detention centres and enforcement contracts.
The Big Players
Serco (UK)
Runs prisons, escort services, and immigration detention. Profitable but tainted by fraud investigations over electronic tagging.
G4S (UK, now U.S.-owned via Allied Universal) Operates prisons and immigration centres. Famously failed during the 2012 Olympics security contract.
GEOAmey (UK)
Formed in 2011 as a joint venture between GEO Group (US) and Amey (UK). Specialises in prisoner escort. Losing its Scottish contract in 2027 after repeated failings.
Sodexo (France/UK)
Runs several prisons under contract.
Mitie (UK)
Recently awarded the Scottish escort contract, replacing GEOAmey.
GEO Group (US
Parent of GEOAmey, but in the U.S. it is a major private prison operator and ICE supplier.
CoreCivic (US): Alongside GEO Group, dominates ICE detention contracts.
Scandals and Fraud
Electronic Tagging Fraud (UK): Serco and G4S were found to have charged the government for monitoring offenders who were dead, back in prison, or had left the country.
Serco paid £19.2m in fines and £12.8m compensation.
G4S paid £38.5m in settlements.
Rewarding Failure
Despite these fraud findings, both firms later won new contracts worth hundreds of millions.
GEOAmey Failings (Scotland): Escapes, missed hospital appointments, and missed funerals led to public outrage and the loss of its contract.
GEO Group & CoreCivic (USA): Criticised for profiting from ICE detention, with allegations of poor conditions and human rights abuses.
Why Outsourcing Was Profitable
Long-Term Contracts: Multi-year deals worth hundreds of millions provided steady revenue.
Recurring Income
Prisoner escort and detention are constant needs, guaranteeing demand.
Global Reach
Companies leveraged contracts across multiple countries, spreading risk and maximising profit.
The Accountability Gap
Transparency Issues: Private firms often hide behind "commercial confidentiality," limiting scrutiny.
Ethical Concerns
Critics argue incarceration should never be a profit centre.
Foreign Ownership
UK taxpayer money now flows to U.S. corporations—G4S is owned by Allied Universal, GEOAmey by GEO Group.
Is It Time to Take Services Back?
The case for renationalisation is strong:
Direct Accountability
Failures would be political, not contractual.
Transparency
Public services are subject to Freedom of Information and parliamentary oversight.
Ethics
Removing the profit motive restores justice as a public good.
But governments resist. Outsourcing promises lower costs and flexibility. Renationalisation would mean higher upfront spending, recruitment drives, and restructuring. The question is whether trust and transparency are worth the price.
What Public Control Would Restore
Clear accountability to ministers and parliament.
Transparency through FOI and public reporting.
Ethical clarity—no profit motive in incarceration.
Consistency of service across regions.
Public trust in justice services.
Profit versus Justice
The history of prisoner security outsourcing is a story of ambition, scandal, and profit. From the first private prison in 1992 to today's billion-pound contracts, outsourcing has reshaped justice in the UK and USA. But the controversies—fraud, escapes, poor conditions, foreign ownership—raise a simple question: should justice ever be for sale?
If governments want to restore trust, it may be time to end the experiment and bring prisoner security back into public hands. After all, justice is not a commodity—it's a cornerstone of democracy.
