The Home Office has issued a further update to its Workers and Temporary Workers sponsor guidance, effective 20 May 2026. This is the latest in a series of changes in 2026, and continues the trend of refining sponsor obligations while maintaining a clear focus on enforcement.
We summarise the key points for sponsor licence holders below.
Right to work checks – Rollback of April changes
The most notable amendment is the reversal of the expanded right to work check requirement introduced in April 2026.
The April guidance extended the obligation to individuals “directly engaged” by a sponsor (even where not employees), which raised significant practical concerns. The May update removes this concept and restores the previous, narrower position.
Sponsors must now carry out right to work checks on:
- workers they sponsor (including those who are not direct employees); and
- workers they employ (whether sponsored or not).
This brings the guidance back into closer alignment with illegal working legislation and removes a layer of operational complexity. However, sponsors should not treat this as a relaxation of standards. The guidance continues to link failures in right to work compliance directly to licence revocation and civil penalty risk, and we expect scrutiny in this area to remain high.
Tightening of the “operating or trading” requirement
The Home Office is also taking a more structured and restrictive approach to what constitutes a business being “operating or trading” in the UK for organisations holding a sponsor licence.
Whilst there is still no statutory definition, the updated guidance clarifies that:
- “trading” refers to the provision of goods or services for reward; and
- “operating” includes both active service delivery (including by not‑for‑profits) and genuine pre‑trading activity where commercial operations are expected to commence in the foreseeable future.
In practice, this change is less about definition and more about threshold. The Home Office is increasingly testing whether sponsors have a genuine and credible UK presence, as opposed to being established primarily to support immigration outcomes.
Where a business cannot demonstrate that it is genuinely operating or trading, the Home Office is likely to refuse a licence application or revoke an existing licence. The guidance now includes examples where this requirement will not be met.
Sponsors should ensure that any sponsored role is clearly anchored in a real business activity, supported by appropriate infrastructure, financial substance and workforce. This aligns with the broader compliance shift towards assessing role credibility and organisational substance, rather than relying on formal structures alone.
New ground targeting “self-sponsorship”
The guidance introduces an express refusal and revocation ground aimed at so‑called “self‑sponsorship” arrangements.
The Home Office may take action where it has reasonable grounds to suspect that an organisation:
“has been established, or exists, mainly to facilitate the entry or residence of a person who would not otherwise have permission to work in the UK or do the work in question”.
This is a significant development. It formalises an approach the Home Office has increasingly taken in practice and reinforces the focus on intent, business substance and role genuineness.
Sponsors—particularly start‑ups, owner‑managed businesses and entities closely linked to a single sponsored individual—should expect closer scrutiny at application stage and during compliance activity.
Clarifications and technical amendments
The update also includes a number of technical amendments and clarifications, including to appendices and record‑keeping expectations. While not headline changes, these reinforce the need for accurate and consistent compliance systems.
Ongoing expectation to remain up to date
A key takeaway is the frequency of change. The sponsor guidance has been updated several times in 2026 alone.
The Home Office position is clear: sponsors are expected to review the guidance in full, keep abreast of changes, and ensure their systems reflect the current requirements at all times. Reliance on outdated processes is unlikely to be a mitigating factor in enforcement action.
What this means for sponsors
The rollback of the April right to work changes simplifies process but does not reduce compliance risk.
The Home Office continues to move towards earlier and more decisive enforcement, including on the basis of perceived risk rather than proven breach.
There is a clear shift towards assessing business substance, role credibility and governance, not just technical compliance.
Recommended actions:
- Review right to work check processes against the updated position.
- Assess whether your organisation can clearly evidence that it is operating or trading in the UK.
- Audit sponsored roles to ensure they are aligned with genuine business activity and need.
- Review governance, record‑keeping and internal audit processes.
- Ensure relevant personnel are trained on the latest version of the guidance.
