Home Office Boosts Civil Penalties for UK Employers of Illegal Workers: The UK government is introducing tougher enforcement measures against employers who hire workers without the legal right to work in the United Kingdom. With significantly higher fines, increased workplace inspections, and stricter compliance expectations, businesses across all sectors must review their right-to-work procedures immediately.
The latest update signals one of the biggest changes to employer compliance since civil penalties were first introduced in 2008.
Immigration Enforcement Steps Up Workplace Raids
In an update issued on 18 July, immigration consultant Five Star International says that Immigration Enforcement teams are ramping up on-site raids and penalty notices as the Home Office is set to quadruple its enforcement budget by 2028/29. Data given to the company shows visits for unlawful working up 34% and arrests up 25% since the Starmer government assumed power in 2024.
The increase in enforcement activity reflects the government’s renewed focus on tackling illegal working across the UK, particularly in industries where labour shortages have created compliance challenges.
Maximum Civil Penalty to Rise to £100,000
From August 2026, the maximum civil penalty for knowingly employing someone without the right to work will increase from £60,000 to £100,000 per illegal worker – the greatest increase since sanctions were introduced in 2008.
This substantial increase highlights the financial risks employers now face if they fail to carry out proper right-to-work checks or maintain ongoing compliance.
Repeat Offenders Face Additional Consequences
Repeat offenders might also be named and shamed on GOV.UK and banned from having a sponsor licence for up to 5 years.
Beyond financial penalties, reputational damage and restrictions on sponsoring overseas workers could significantly affect businesses that rely on international recruitment.
Industries Under Increased Scrutiny
The Home Office said the tighter policy reflected ongoing exploitation in construction, hospitality and adult social care, which are already facing significant workforce shortages.
These sectors are expected to receive greater attention from Immigration Enforcement officers as workplace inspections increase.
Why Right-to-Work Checks Alone Are No Longer Enough
The message for international businesses is blunt: onboarding right-to-work checks alone are no longer sufficient.
Employers are now expected to adopt continuous compliance practices rather than relying solely on checks completed at the time of recruitment.
Best Practices for HR and Mobility Teams
Mobility and HR teams should conduct rolling audits, especially for sponsored workers nearing the end of their visa, and make sure that their document verification technology is current with the latest BRP and eVisa formats.
Regular internal audits and updated verification systems can help organisations identify compliance issues before they result in enforcement action.
Agency Workers Also Require Compliance
Companies using agency employment should include compliance clauses in contracts and obtain verification of status for each worker supplied to them.
Businesses cannot assume recruitment agencies have completed all necessary checks, making contractual compliance safeguards increasingly important.
Global Mobility Policies Should Be Reviewed
Legal practitioners also recommend a reassessment of global mobility policies.
Many international assignees travel to the UK on short-term secondment visas that do not allow for local external postings; the unintended breaking of these regulations now comes with greater financial and reputational cost.
Organisations with internationally mobile employees should ensure visa conditions are fully understood before assigning staff to UK-based projects.
Preparing for Immigration Enforcement Visits
“The increase in raids on sites means that companies should train reception and security staff about what to do when enforcement officers arrive with warrants.
Having clear procedures in place can help businesses respond appropriately during an inspection while maintaining compliance with legal requirements.
Employers Have Limited Time to Prepare
Parliament still has to approve the new punishment levels, but officials say there is bipartisan support. Employers have only weeks to rectify compliance gaps before the harsher fines take effect, making proactive auditing an important board-level responsibility.
With enforcement activity continuing to increase, employers are encouraged to review their compliance systems, update right-to-work procedures, and ensure HR teams remain informed about the latest immigration requirements.
