Background
Blue Inn Limited is a construction staffing company licensed to sponsor skilled migrant workers under the UK immigration system. Between September and October 2024, the Home Department’s Compliance Team conducted an unannounced visit, interviewing the company’s director and two sponsored civil engineers. The visit identified concerns that the company was supplying workers to third parties as labour rather than retaining responsibility for them as a direct employer. The Home Department also questioned whether certain roles constituted genuine vacancies and alleged underpayment relative to contracted hours.
On 27 February 2025, the Home Department suspended Blue Inn’s licence, citing alleged breaches of three sponsor duties: (1) supplying sponsored workers as labour to third parties in contravention of paragraphs S1.29, C1.44, and C1.46 of the sponsor guidance; (2) assigning a certificate of sponsorship (CoS) for a role that was not a genuine vacancy; and (3) paying a sponsored worker less than stated on his CoS whilst failing to report the change in hours as required by paragraph SK11.25 of the guidance. The company was given 20 working days to respond. On 25 March 2025, the company submitted representations accompanied by letters from the third-party contractors (CIDON Construction and Modebest Builders) confirming they had engaged Blue Inn as a subcontractor with full responsibility for the engineers, and evidence supporting its other defences.
On 15 April 2025, the Home Department revoked the licence, citing mandatory grounds of revocation under Annex C1(x), (z), and (aa) of the sponsor guidance.
The Court’s Holding
The court (Tom Little KC, sitting as Deputy High Court Judge) examined whether the Home Department’s revocation decision was lawful, focusing on the three disputed sponsor duties as agreed dispositive by the parties. [Note: The opinion as provided is incomplete and cuts off mid-paragraph; the following reflects the structure and issues identified but cannot fully state the court’s final conclusion.]
On General Duty 1 (labour supply), the court considered the competing evidence. The company produced contemporaneous letters from both third-party contractors explicitly confirming that Blue Inn had been engaged as a subcontractor with full responsibility for direction, control, and supervision of the engineers—not as a labour-hiring agency. The earlier email from Modebest Builders’ managing director stating the company “were a labour agency” was contradicted by Modebest’s later detailed letter distinguishing between two roles: subcontractor work (for the engineers) and separate labour supply services (for general labourers), only the latter falling under the labour-supply arrangement. This contemporaneous documentary evidence from the principals themselves appeared directly relevant to whether the workers in question had in fact been supplied as labour or retained under direct responsibility.
On General Duty 2 (genuine vacancy), the company established that the job interview notes were dated 2 May 2023, prior to the CoS assignment on 7 May 2023, contrary to the Home Department’s initial concern. The interview content also aligned substantively with the CoS job description across multiple specific duties (word processing, spreadsheets, database management, site visits). The company further supplied a letter from the worker himself confirming his day-to-day duties matched the CoS description.
On General Duty 3 (payment and hours), the company demonstrated that the timesheets cited by the Home Department included a 1-hour break, bringing the net working hours into line with the 45-hour weekly contract. The company also produced its standard code of conduct showing that all sponsored workers, including the one in question, had agreed to opt out of the Working Time Regulations 1998, explicitly permitting overtime. The company asserted that the worker had been paid for all overtime through a December 2024 salary adjustment.
Key Takeaways
- When a sponsor licence is suspended pending investigation, the Home Department must fairly assess credible, contemporaneous documentary evidence from third parties—here, the explicit letters from both contractors directly contradicting the earlier informal email and confirming subcontract status.
- The sequence of interview and CoS assignment is material: dated interview notes proving the job interview preceded the CoS can rebut the inference that a vacancy was created merely to facilitate migration.
- Sponsor duties must be interpreted in light of the company’s documented employment arrangements: a worker may lawfully work overtime beyond the contracted hours if the employee has agreed to opt out of the Working Time Regulations, and proper payment through salary adjustments satisfies the “payment” duty.
- The Home Department’s obligation to provide clear notice of required documents and evidence means that gaps in information produced during the initial investigation may be remediable through substantive representations—the company was not fairly held to an impossibly narrow defence.
Why It Matters
The sponsor licence system is the cornerstone of UK labour migration. Sponsors must satisfy stringent duties to prevent abuse, but the court’s approach here emphasizes that revocation—a draconian remedy that can destroy a company’s operations—requires careful evidentiary analysis of the actual contractual and operational reality, not inferences drawn from selective pieces of correspondence. The decision clarifies that third-party confirmations of the sponsor’s actual role (subcontractor versus labour agency) are directly relevant to whether the sponsorship duties have truly been breached, and that a company’s written policies on opt-outs and overtime payment arrangements are relevant to determining compliance.
This case will be important for construction and staffing firms that work through subcontracting arrangements whilst sponsoring skilled migrant workers. It signals that the courts will scrutinize the Home Department’s factual findings—particularly those resting on an initial email that was later contradicted by the same source—before confirming a revocation that carries severe commercial consequences.
