UK Firms Hit with Over £28m in Fines for Illegal Workers in Just Three Months

UK businesses are facing a severe financial reckoning as the Home Office releases its latest enforcement data, revealing that employers were slapped with over £28 million in civil penalties for illegal working breaches between April and June 2025 alone.

The report, released late yesterday (28 November), underscores the government’s continued aggressive stance on immigration enforcement and the severe financial risks facing employers who fail to conduct proper Right to Work checks.

A Steep Price for Non-Compliance

According to the Home Office data covering the period from 1 April to 30 June 2025, the total gross value of penalties issued reached £28,295,000.

What is particularly striking about this quarter’s figures is the high average cost per breach.

Total Penalties Issued: 548

Illegal Workers Found: 712

When analysed, these figures suggest an average fine of roughly £51,600 per employer caught, and approximately £39,700 per illegal worker found.

This sharp spike in penalty value reflects the policy changes implemented in 2024, which saw the maximum civil penalty for employing illegal workers triple, rising from £15,000 to £45,000 per worker for a first breach, and up to £60,000 per worker for repeat offenders. The Q2 2025 data confirms that these higher tariffs are now being applied with full force.

The Home Office noted that the £28.3 million figure represents the “gross value” of penalties issued. The final amount recovered by the Treasury may ultimately be lower.

“The recoverable value will be reduced due to adjustments made following objections and/or appeals,” the report stated.

A Warning to Employers

This latest data release serves as a stark warning to UK employers across all sectors particularly hospitality, construction, and care that the Home Office is maintaining a high operational tempo regarding enforcement raids and audits.

With 712 illegal workers identified in just a 90-day window, the message is clear: the onus is entirely on the employer to verify immigration status before a staff member begins work.
