Illegal working arrests double in two years, Home Office says

Home Secretary Shabana Mahmood, commenting on the unprecedented figures, stated, "This surge in enforcement activity takes us to the highest level in British history. We are sending a clear message: illegal workers and rogue employers have nowhere to hide." The declaration signals a robust, zero-tolerance approach, suggesting that the government is deploying increased resources and refining intelligence-led operations to dismantle networks facilitating illegal employment. This historical peak in enforcement is attributed to a multi-pronged strategy encompassing enhanced data analytics, improved cross-agency intelligence sharing, and a greater number of frontline immigration enforcement officers dedicated to these operations.

However, the opposition Reform UK party quickly dismissed these figures as disingenuous, accusing the Labour government of "insulting the intelligence of the British public." Reform UK’s home affairs spokesman, Zia Yusuf, argued that despite the reported increase in arrests, the visible presence of illegal working continues to grow across the country, suggesting that the government’s efforts are either insufficient or merely playing catch-up to an escalating problem. He reiterated Reform UK’s long-standing position that lax immigration controls have fostered an environment where illegal employment can thrive, thereby acting as a powerful "pull factor" for migrants, including those crossing the Channel in small boats.

Indeed, the trend of increasing arrests during immigration raids on businesses had already begun to accelerate prior to Labour assuming office in July 2024. The latest statistics, however, indicate a significant intensification post-transition. Since July 2024, there has been a notable 50% rise in individuals being returned to their home countries, totalling 2,357. These returns are a critical component of immigration enforcement, aiming to deter future illegal entry and residence, though the process itself is often complex, costly, and subject to legal challenges.

The first six months of the current year have witnessed a substantial increase in enforcement operations, with immigration raids escalating to 7,270 – a 31% rise compared to the same period last year. These operations led to 4,756 arrests, marking a 20% increase. Raids are typically intelligence-led, targeting businesses suspected of employing undocumented workers, often identified through public tip-offs, data analysis, or previous enforcement actions. The targeted sectors frequently include those with high cash turnover and demand for low-skill labour, making them susceptible to exploitation.

Geographically, the highest rates of arrest were concentrated in major economic hubs and regions with specific industrial characteristics. London led the nation with 1,256 arrests, representing a 32% increase on the same period in the previous year. The capital’s diverse economy, large population, and established networks for both legitimate and illicit employment make it a perpetual hotspot for such activity. The West Midlands followed, recording 701 arrests, a 22% increase, likely reflecting its significant manufacturing, logistics, and hospitality sectors. South West England experienced the most dramatic percentage rise, with 693 arrests marking a substantial 44% increase. This regional surge may be linked to seasonal agricultural work, tourism, and expanding construction projects, which often attract vulnerable labour.

The financial repercussions for employers found to be flouting immigration laws have also intensified dramatically. So far this year, businesses have been hit with a staggering £74 million worth of civil penalties. These penalties are designed to deter employers from hiring illegal workers and typically vary based on the number of illegal employees, the employer’s cooperation with enforcement, and whether it’s a first-time or repeat offence. Fines can range from £15,000 per illegal worker for a first offence, escalating to £60,000 for repeat offenders, alongside potential criminal prosecution in severe cases.

The sectors most frequently targeted and penalised include beauty salons, retail outlets, and hospitality venues, which often operate with high staff turnover and may be perceived as offering easier avenues for undocumented workers to find employment. Companies have a clear legal responsibility to verify that all individuals they employ directly have the right to work in the UK. For agency workers, this responsibility typically rests with the recruitment agency to conduct the necessary checks, including scrutinising passports, visas, and other documentation. Failure to perform these checks diligently is not merely a technical oversight but a serious legal breach.

Opposition parties have consistently warned that the availability of opportunities for illegal work in the UK acts as a significant "pull factor" for migrants. This argument posits that the prospect of earning money, even if under exploitative conditions, incentivises individuals to undertake dangerous journeys, such as crossing the Channel in small boats. They contend that by making it harder for illegal migrants to find work, the government could reduce the incentive for illegal immigration.

Reform UK, taking a more radical stance, announced on Thursday its intention to introduce a system that would pay members of the public for tip-offs that lead to successful prosecutions of High Street shops employing illegal workers. This proposal aims to leverage public vigilance as a primary source of intelligence, though it raises questions about potential misuse, false accusations, and the creation of a ‘bounty hunter’ culture. Furthermore, the party pledged to fine large firms up to 10% of their global revenues for employing illegal workers, a measure intended to hit corporate profits hard and force greater compliance. Perhaps most significantly, Reform UK also proposed making chief executives and directors criminally liable for illegal working within their organisations, a move designed to elevate accountability to the highest levels of corporate governance and impose personal consequences for corporate failings.

Zia Yusuf, elaborating on Reform UK’s position, asserted: "The British public can see the scourge of illegal working growing all around them. Labour is only insulting their intelligence by claiming it is not." This statement reflects a deep scepticism within Reform UK regarding the government’s narrative and efficacy, suggesting that the problem is endemic and requires far more drastic solutions than current policies offer.

In response, the Home Office maintains that it is already actively increasing penalties for companies caught hiring illegal workers, as evidenced by the significant fines levied this year. They argue that these measures, combined with the heightened enforcement activity, are part of a comprehensive strategy to deter both illegal workers and rogue employers. Shadow home secretary Chris Philp, earlier this year, echoed the sentiments of some critics, stating that "illegal working is booming because Labour have turned Britain into a soft touch." This highlights the political battleground that immigration enforcement has become, with both sides trading accusations over effectiveness and policy approaches.

Looking ahead, the government is set to introduce even tougher measures. From 1 October, employers caught hiring illegal workers in the gig economy – such as delivery riders, couriers, or other platform-based roles – could face fines of up to £60,000 per illegal worker. In addition to these substantial financial penalties, individuals responsible could also face up to five years in prison. This specific targeting of the gig economy reflects growing concerns that the sector, with its often informal employment structures and reliance on self-employment models, has become a fertile ground for illegal working, making it a priority for enhanced scrutiny and enforcement. The Home Office asserts that these escalating penalties and intensified operations are crucial to maintaining the integrity of the UK’s labour market and immigration system, aiming to create an environment where illegal employment is simply not viable.
