"UKVI assesses the reality of work, not just the labels in contracts or business structures."
Disguised employment, where an arrangement labelled as self-employment or business activity effectively mirrors employment, is a critical compliance concern in UK immigration. An arrangement that amounts to disguised employment can lead not only to refusals but also to retrospective scrutiny at the stage of Indefinite Leave to Remain (ILR). Maintaining clear and consistent documentation and robust evidence is essential to safeguard long-term immigration status.
ECAA Routes: Closed but Still Relevant
The ECAA Ankara Agreement routes, covering both Businessperson and Turkish Worker categories, are closed to new applicants following the UK's exit from the EU. Nevertheless, these routes remain highly relevant for those who were granted ECAA leave prior to closure.
UK Visas and Immigration (UKVI) continues to examine compliance with Appendix ECAA, the genuineness of business or employment, and potential disguised employment issues. This scrutiny applies to extension applications and ILR, where the authority may review an applicant's entire immigration history, including historic working arrangements.
For existing ECAA leave holders, the rules discussed in this article remain fully applicable and provide useful comparative insights for other immigration routes, including the Skilled Worker visa.
Understanding Disguised Employment
Disguised employment arises when the work performed is, in effect, employment, even if labelled otherwise. UKVI evaluates the actual working arrangements, including the degree of control exercised over the worker, financial risk and independence, integration into the client's organisation, and the right to delegate or substitute work. The number and independence of clients is also considered. These principles are applied consistently across immigration categories and are not limited to ECAA or self-employment cases.
If the arrangements are not genuine, this can affect credibility under Part 9 – Suitability, potentially resulting in refusal and a ban of entry.
ECAA Businesspersons and Turkish Workers
For ECAA Businesspersons, applicants must demonstrate the genuine operation of a business in the UK. Evidence should reflect a viable enterprise, autonomy over operations, financial investment, and decision-making authority. If UKVI determines that the applicant's activities amount to employment in disguise, the application may be refused.
ECAA Turkish Workers are required to show that their employment is genuine and consistent with visa conditions. Any material divergence from declared working arrangements may result in refusal on extension or future applications.
"Even though ECAA routes are closed to new entrants, compliance and documentation remain essential for existing holders."
Skilled Worker Visas and Supplementary Employment
Skilled Worker visa holders are subject to scrutiny for disguised employment, particularly when undertaking supplementary or third-party work. UKVI assesses the reality of the working arrangement, not merely the contractual label or business structure. Where supplementary work begins to resemble employment with another organisation, or undermines the sponsored role, this may raise compliance concerns.
Supplementary employment is permitted only where the individual continues to work for their sponsor in the sponsored role, and the additional work:
- is undertaken outside the contracted hours of the sponsored employment;
- does not exceed 20 hours per week; and
- falls within the permitted scope of supplementary employment under the Immigration Rules.
The supplementary role must either be:
- in the same profession and at the same professional level as the sponsored role; or
- in an occupation listed in the Immigration Rules, Appendix Immigration Salary List.
In addition, supplementary employment must be in an eligible SOC 2020 occupation code listed in Tables 1, 2 or 3 of Appendix Skilled Occupations. For individuals who were granted Skilled Worker permission before 22 July 2025 and who have maintained continuous permission, supplementary employment may also include occupations listed in Tables 1a, 2aa or 3a, reflecting transitional protections under the Rules.
From 4 April 2024, supplementary employment was expanded to include all roles eligible for new Skilled Worker applications, not solely those on the former Shortage Occupation List. However, from 22 July 2025, the minimum skill level for supplementary employment increased. As a result, individuals granted Skilled Worker permission on or after that date are generally restricted to supplementary work at RQF6 level or in the same occupation code as their sponsored role. Lower-skilled supplementary roles are typically available only to those benefiting from transitional arrangements.
Self-employment or running a business can constitute supplementary employment only where it meets all of the above conditions. Where supplementary work exceeds 20 hours per week, falls outside eligible occupation codes, or interferes with the sponsored role, the individual must obtain a new Certificate of Sponsorship and vary their leave accordingly.
Even where supplementary employment is technically permitted, UKVI may examine whether it has become the dominant or substantive employment. If the sponsored role appears secondary, or the individual is effectively controlled by another organisation, this may indicate disguised employment. Such findings can adversely affect credibility and may lead to refusal under Part 9 – Suitability, with potential long-term consequences including a re-entry ban. Any contractual restrictions, including competition clauses, must also be carefully considered.
Employers engaging Skilled Worker visa holders for supplementary employment must carry out appropriate right-to-work checks and retain evidence confirming that the worker remains employed by their sponsor. This includes obtaining confirmation of the sponsored role, occupation code and contractual working hours. Failure to act where a breach is suspected may result in loss of the statutory excuse.
IR35 Considerations
Although IR35 is a tax regime, UKVI increasingly considers its determinations as indicative of the true nature of a working arrangement. If an engagement is deemed "inside IR35," it suggests that the worker functions as an employee, reinforcing concerns about disguised employment. Applicants should ensure alignment between contracts, working practices, and tax treatment.
Documentation and Evidence
Supporting evidence is critical. Contracts should reflect actual working practices, while business records, invoices, and tax returns must be consistent with claimed independence or self-employment. Evidence of multiple clients and financial risk further substantiates the genuineness of a business operation. Inconsistencies across HMRC filings, Companies House records, or immigration submissions may undermine credibility and increase the risk of refusal.
"Consistency across documentation is crucial to avoid raising doubts about the nature of work and to maintain credibility under Part 9 – Suitability."
ILR and Retrospective Scrutiny
At ILR stage, UKVI may review the applicant's entire immigration history, including previous grants of leave and historic working arrangements. If disguised employment is identified retrospectively, ILR may be refused, highlighting the importance of maintaining compliance throughout the qualifying period.
Disguised employment remains a significant compliance risk across multiple UK immigration routes. Applicants and advisers must focus on the substance of working arrangements, maintain clear and consistent documentation, and ensure alignment with tax and employment principles, including IR35. Awareness of supplementary employment rules for Skilled Workers is equally critical. Failing to provide genuine evidence or attempting to disguise employment can undermine credibility under Part 9 – Suitability, potentially resulting in refusal. Following these principles safeguards both current and future immigration status, including eligibility for earned settlement and eventual citizenship.
