Corporate transactions are rarely assessed through an immigration compliance lens. However, for UK businesses that hold a sponsor licence, changes in ownership, control, or corporate structure can have immediate and significant consequences for their ability to employ sponsored workers.
For businesses reliant on international talent, disruption to a sponsor licence can affect recruitment capability, workforce continuity, operational stability, and ultimately transaction value.
We increasingly see transactions where sponsor licence implications are identified too late in the process or overlooked entirely. In serious cases, this can lead to regulatory breaches, sponsor licence suspension or revocation, and the loss of key sponsored personnel.
Sponsor licences are granted to a specific legal entity based on the structure, ownership, and operating arrangements in place at the time of application. A sponsor licence is not a transferable asset. Where ownership or control changes, the Home Office may need to be notified, and in some cases a fresh sponsor licence application may be required.
As a result, a transaction which appears straightforward from a corporate perspective can create significant immigration compliance risks if sponsor licence issues are not considered at an early stage.
The distinction between transaction types is also important. In a share sale, the employing entity usually remains the same, although ownership and control may change. In an asset sale, the employing entity itself changes, giving rise to different legal and practical consequences for both the business and its sponsored workers.
Corporate transactions which may trigger changes to a sponsor licence
From a corporate perspective, several transactions can inadvertently trigger changes to a sponsor licence. This can cover situations where there is a private equity investment resulting in a change of control, group restructures, management buyouts or transactions affecting voting rights/control.
1. Change in direct ownership of your organisation or business
If a business is sold as a going concern, or a share sale results in a controlling interest being transferred to a new owner, the organisation may no longer be able to rely on its existing sponsor licence following the transaction. The organisation may be required to apply for a new sponsor licence. In some cases, the existing licence may be revoked or made dormant.
Practical example: shareholding changes and sponsor compliance
This example illustrates how sponsor compliance issues can arise unexpectedly from internal business decisions. A company transferred 50% of its shares in equal parts to two key sponsored employees as part of a retention strategy during a difficult recruitment period. Following the transaction, the employees were registered as Persons with Significant Control (PSC) at Companies House. When the company later requested an additional Certificate of Sponsorship allocation, the Home Office identified the change during routine due diligence checks.
Although the shares were transferred back, the Home Office considered the change in ownership and control sufficient to require a fresh sponsor licence application within 20 working days. The company had also failed to report the shareholding and PSC changes within the required timeframe, which resulted in the new licence application attracting a digital compliance audit to assess its HR systems and compliance procedures.
While the new sponsor licence was ultimately granted, the process took several months and had significant commercial consequences. During this period, the company could not assign new Certificates of Sponsorship and ultimately lost a valuable sponsored employee whose visa could not be extended in time.
The key lesson is that even seemingly minor changes to ownership, shareholding, or control structures can trigger serious sponsor licence implications and should always be assessed and reported promptly where required.
Whether a new sponsor licence is required will depend on the nature and extent of the change in ownership or control.
2. Complete takeovers or mergers (TUPE or similar protection)
Alternatively, when a business changes owner, or another business takes over part of it or a service it provides, its employees may be protected under the Transfer of Undertakings (Protection of Employment) Regulations 2006 (‘TUPE’).
Where a sponsored worker transfers under TUPE or similar statutory protection provisions, their employment is treated as continuing the same terms and conditions. In these circumstances, the worker does not usually need to submit a new visa application solely because of the TUPE transfer, and the new employer does not need to assign a new Certificate of Sponsorship. That is, provided the new employer holds a valid sponsor licence, accepts responsibility for the worker, and the role itself remains unchanged.
The new sponsor must report the transfer to the Home Office within 20 working days. Where the receiving employer does not already hold an appropriate sponsor licence, it will generally need to apply for one within 20 working days of the transfer taking place. Failure to obtain a licence or a refusal of the application can result in the sponsored workers having their permission curtailed.
3. Partial takeovers, restructuring or demergers
Different considerations apply in cases involving partial takeovers, business restructures, or demergers. In those circumstances, the required sponsor compliance steps will depend on whether the organisation is the transferring sponsor, the receiving sponsor, and whether sponsored workers remain employed by the original entity following the restructure.
Corporate transactions often operate on compressed timelines, whereas sponsor compliance obligations impose strict reporting deadlines. Failure to comply with these obligations can result in sponsor licence compliance action, including suspension or revocation, and in serious cases may ultimately affect sponsored workers’ immigration permission.
Legal due diligence
Immigration compliance should form part of standard transactional due diligence, particularly where the target business employs sponsored workers.
Key questions when looking to buy or invest in a company include:
- Is the sponsor licence valid and active?
- Are right-to-work checks properly documented?
- Does this transaction trigger the requirement to apply for a new sponsor licence?
- If the transaction involves the acquisition of a controlling interest in a sponsor licence holder, are the parties aware of the relevant sponsor compliance obligations?
- What reporting requirements are relevant to the transaction?
- What are the reporting deadlines in relation to the completion of this transaction?
- Whose responsibility is it to report: the buyer, seller, or both?
Structuring solutions and protections
From a corporate drafting perspective, risks for buyers and investors can be mitigated by including sponsor licence-related warranties, indemnities, and conditions precedent within the transaction documents
Key takeaways
Sponsor licence compliance should form part of standard transactional due diligence and deal structuring. Changes in ownership, control, or employing entity can trigger mandatory reporting obligations, fresh sponsor licence applications, and potential disruption to sponsored workers if not managed correctly.
