The Home Office illegal working register: what the published penalties do and do not prove.

The Home Office describes the report as listing employers that received civil penalties for illegal working. The stated publication criteria concern employers that have not paid or are not making regular payments 28 days after exhausting objection or appeal rights, and employers receiving a second or later penalty after those rights are exhausted regardless of payment.

That selection matters. An employer absent from the public report is not necessarily free of enforcement exposure, and the presence of a business name does not tell a reader everything about the current corporate structure, the affected workers or any subsequent remediation.

The date on the publication must also be distinguished from the quarter covered. An update in July 2026 relating to October to December 2025 should not be presented as a current month count or as a live record of all recent Home Office visits.

The government's employer guidance states that a civil penalty can be up to £60,000 for each illegal worker. The actual amount and available response depend on the circumstances, the applicable code of practice and the decision taken in the particular case.

Commercial consequences may also include contractual disclosure issues, transaction questions, management time, insurance considerations, customer scrutiny and potential implications for a sponsor licence. None of those consequences should be assumed to arise automatically in every case.

A referral notice, a civil penalty notice and a published finalised outcome are different procedural events. Treating them as interchangeable can distort the advice given to the employer, the buyer or any professional adviser reviewing the position.

A right to work review should identify who is the legal employer, how checks are carried out before work begins, when follow up checks are needed and whether evidence has been retained in accordance with the applicable guidance.

Particular care is needed where a business uses several sites, centralised recruitment, outsourced staffing, agency arrangements or acquired teams. The practical allocation of responsibility must be tested against the contractual and employment structure rather than inferred from who arranged a shift.

For a licensed sponsor, right to work controls form part of a wider compliance picture. An enforcement concern may justify a connected review of sponsored roles, payroll, work locations, reporting and key personnel even where the public register itself contains limited detail.
