Immigration enforcement has become far more visible in the UK over the past year, and recent figures suggest that scrutiny of workplaces is only increasing. A widely shared update reported that immigration raids and arrests are at their highest level in British history. Raids on businesses have risen significantly, arrests linked to illegal working are up, and removals of people without legal status have also increased.
For employers, the most important detail is not just the scale of the numbers. It is the focus of the activity. The update described raids on everyday businesses, including nail bars, car washes, barbers and takeaway shops. These are the types of workplaces where recruitment can be fast paced, staff turnover can be high and hiring processes can be more informal than they should be.
The same report also referenced enforcement action in Greater Manchester. It described raids linked to a suspected people smuggling and money laundering investigation, with warrants executed across locations including Bolton, Sale, Bramhall, Salford, Leigh and Cheadle, plus one address in London. In that case, arrests were made and investigators seized cash, phones and documents.
Cases like this can feel distant if you run a legitimate business and try to do things properly. But the broader message is relevant to any employer. Increased enforcement activity means it is more likely that gaps in hiring processes will be discovered. It also means that employers need to be able to demonstrate compliance clearly, not simply assume that good intentions will be enough.
Why this update should concern ordinary employers
When people hear about immigration raids, they often assume the focus is on businesses that are deliberately employing illegal workers. In reality, enforcement action also exposes businesses that have simply been careless, inconsistent or too reliant on outdated processes.
Most small and medium sized businesses do not have a dedicated HR function. Hiring is often managed by busy owners, managers or supervisors, sometimes under pressure. Shifts need covering, projects need people and recruitment decisions get made quickly. In these conditions, it is easy for checks to become rushed or inconsistent, especially if the business has grown and processes have not kept up.
Increased enforcement does not automatically mean that all workplaces are doing something wrong. It does mean that employers are more likely to be asked to prove that they have done the right checks, at the right time, using the correct method, and that they have kept the right records.
How businesses can unknowingly hire someone illegally
It is entirely possible for an employer to hire someone who does not have the right to work in the UK without realising it. That is not a comfortable thought, but it is a practical risk that comes up again and again.
One of the most common scenarios involves time limited permission to work. A person may have had the right to work when they were hired, but that permission later expires. If the employer does not carry out a follow up check when required, the employment may become illegal even though it began lawfully.
Another common issue is documentation that looks convincing. A quick visual check can miss important details, including expired documents, documents that do not belong to the person presenting them or documents that are genuine but do not grant the permission required for the role. Even where employers are cautious, it is easy to be misled without using the correct checking route.
Changes in immigration status can also create risk. A worker’s conditions may change, affecting hours, employer eligibility or job role restrictions. If this is not communicated, or if it is misunderstood, the employer may inadvertently breach the rules while believing everything is still in order.
Informal hiring practices are another frequent cause of problems. Trial shifts are a classic example. A business might want to see how someone performs before completing paperwork. But if the person starts work before the checks are done, even for a short period, the employer has taken on risk unnecessarily.
Agency and subcontractor labour can also lead to complacency. Many businesses assume that a third party has performed the checks correctly. Sometimes they have, but responsibility does not always sit neatly with one organisation. Even when liability is not straightforward, the business using the labour can still face operational disruption, reputational damage and uncomfortable questions if something goes wrong.
The business impact of non compliance
The immediate consequences of illegal working can be severe. Civil penalties can be significant, and directors may face deeper scrutiny if enforcement teams believe the employer should have known. Even when penalties are reduced, the process is stressful and time consuming, particularly for smaller companies.
There is also the disruption caused by enforcement activity itself. Investigations can involve interviews, document requests, seized devices and temporary closures. A business may lose staff unexpectedly or face wider scrutiny of its employment practices.
Reputation is often the biggest issue. If enforcement action becomes public, it can affect trust with customers, suppliers, landlords and partners. In some industries, reputational damage can take far longer to repair than the financial impact of any penalty.
Practical steps to reduce risk when hiring
The good news is that many of the most common issues are preventable. The key is consistency.
Employers should have a standard process that applies to every hire, regardless of role, seniority or urgency. Checks should not be optional, and they should not vary depending on who is recruiting on a particular day.
Right to work checks must be done using the correct method for that individual. Evidence should be recorded and stored securely, with clear dates. Where permission to work is time limited, follow up checks should be diarised so that compliance does not depend on memory or informal reminders.
Training matters too. Hiring is often delegated to managers who are focused on performance and staffing levels, not compliance detail. Even a short internal guide can reduce mistakes, especially in businesses with multiple sites or a rotating management team.
Finally, businesses should review how they handle urgent hiring. If trial shifts or short notice cover are a normal part of your operations, it is worth tightening that process, so checks are always completed before work begins.
Where background checks can add value
Right to work checks focus on immigration status. They do not necessarily verify whether someone is presenting an accurate picture of their identity, history and credibility.
This is where background checks can become relevant as a wider due diligence tool. There a wide number of reliable partners for this service, such as a private investigator. Background checks can help identify inconsistencies, verify identity details and confirm elements of a person’s personal or professional history. They may also highlight potential red flags that sit outside the scope of standard hiring checks.
They can be particularly valuable for roles involving access to client data, cash, stock, keys, private premises or sensitive systems. They can also help where reputation is a major asset and a single hiring mistake could become a costly problem.
Most importantly, they support better decision making. Hiring is always a balance between speed and certainty. Background checks help employers make that decision with more information and fewer assumptions.
Protect your business from unlawful hiring
The recent rise in immigration raids and arrests sends a clear signal that workplace enforcement is increasing across the UK. For employers, the sensible response is not panic. It is preparation.
Businesses that take hiring compliance seriously, standardise their processes and keep clear records will be better protected. And where roles carry higher risk or greater trust, additional due diligence such as background checks can provide reassurance and reduce exposure.
In a climate of increased enforcement, the safest position for employers is simple. Know who you are hiring, know what checks are required and make sure your processes stand up to scrutiny.
