Arrests for illegal working have soared to record levels across the United Kingdom after the Home Office launched the most extensive enforcement operation in its history.
Under Operation Sterling, immigration teams carried out more than 11,000 raids between October 2024 and September 2025, resulting in 8,000 arrests—a 63 percent year-on-year increase.
Government’s Largest Crackdown on Illegal Workers
The unprecedented operation marks a decisive push by Immigration Enforcement to tackle illegal employment across industries long linked to labour exploitation and tax evasion. With a £5 million investment, officers targeted takeaways, beauty salons, car washes, and food-delivery drivers, focusing on locations with high levels of irregular employment.
Home Secretary Shabana Mahmood said the surge in arrests shows the government’s determination to “secure Britain’s borders” and remove the incentive for illegal migration. She added that those found working without legal status “will be arrested, detained, and removed.”
Expanding the Right to Work Checks
While it has always been a criminal offence for migrants to work illegally, only traditional employers were previously obliged to verify immigration status. Under new laws, right-to-work checks will now extend to gig-economy, subcontracted, and casual roles—closing a major loophole in the employment system.
Employers who fail to conduct these checks could face fines of £60,000 per illegal worker, jail terms of up to five years, and potential business closure. Officials say the stricter penalties will deter rogue bosses and protect compliant firms from unfair competition.

Digital ID to Verify Work Status
To strengthen compliance, the government plans to introduce digital ID by the end of the current Parliament. This system will make it mandatory for everyone in the UK labour market to prove their right to work through a secure, digital identity.
Officials believe digitalisation will make it harder to use forged documents and easier to track non-compliant employers. It is also expected to create a simpler, more consistent process for businesses, especially within online recruitment and gig-delivery platforms.
Collaboration with Major Platforms
The Home Office has begun working with major delivery companies, including Deliveroo, Just Eat, and Uber Eats, which have introduced stronger ID verification checks across their networks. A new data-sharing agreement enables the government to cross-reference delivery driver activity and identify individuals staying in asylum accommodation who may be working illegally.
This cooperative approach extends enforcement capacity beyond physical raids, allowing authorities to detect illegal work through digital footprints and platform-level monitoring.
Broader Effect on the Economy and Labour Market
The crackdown aims to protect lawful employment and ensure fair wages. By tackling illegal work, the government seeks to reduce the “black economy”, recover lost tax revenue, and create a level playing field for honest employers.
For small businesses that follow hiring rules, the measures are expected to reduce unfair competition from rivals exploiting unregistered workers. Legal migrants and UK citizens alike benefit from higher compliance standards and safer working environments.
Likely Benefits:
-
Greater fairness in lower-wage sectors
-
Reduced exploitation of vulnerable workers
-
Stronger tax and compliance enforcement
-
More visible deterrence for illegal migration
Political and Social Context
This operation represents a major policy milestone for Home Secretary Mahmood, who is under pressure to demonstrate control over Britain’s borders. It aligns with the wider immigration strategy linking labour enforcement to the reduction of small-boat crossings.
Since taking office, the government has returned 35,000 people with no legal right to stay in the UK—a 13 percent rise in removals—and continues to strengthen partnerships such as the UK-France deal for detaining and returning illegal arrivals.
Consultation and Next Steps
A six-week public consultation on the new right-to-work framework will collect views from employers and industry bodies on implementation details, supply-chain practices, and timing. The Home Office says guidance will ensure businesses understand when and how to perform checks and how to integrate digital ID verification into their recruitment systems.
In Conclusion
The UK’s record-breaking crackdown on illegal working reflects a fundamental shift in how the country enforces immigration law—through technology, collaboration, and tougher penalties.
It also signals the government’s determination to restore confidence in fair employment, reduce illegal migration incentives, and protect legitimate livelihoods across the nation.
