The Home Office has quietly introduced what may prove to be one of the most practically significant sponsor licence guidance updates in recent years: a formal definition of the phrase “operating or trading” for sponsor licence applications.

For many years, businesses applying for a Skilled Worker sponsor licence were required to demonstrate that they were “operating or trading lawfully in the UK”. Yet, despite the importance of this requirement, the Home Office had never clearly defined what “operating or trading” actually meant.

As a result, sponsors, immigration practitioners and compliance officers were often left to interpret the requirement based on fragmented guidance, caseworker practice, previous compliance outcomes and experience of sponsor licence refusals.

That has now changed.

On 20 May 2026, the Home Office updated the Workers and Temporary Workers: guidance for sponsors: glossary to introduce a new formal definition of “operating or trading”. The change forms part of the increasingly detailed and centralised sponsor guidance framework introduced in 2026.

1. The Previous Position: A Critical Sponsor Licence Requirement Without a Definition

The requirement for a sponsor to be “operating or trading” has always sat at the heart of the sponsor licence system.

Part 1 of the sponsor guidance requires sponsor licence applicants to show that they are:

• genuine organisations operating lawfully in the UK; and
• capable of carrying out sponsor duties.

The Home Office has historically expected sponsors to submit evidence demonstrating an active trading presence, such as corporate bank statements, employers’ liability insurance, VAT registration documents, audited or unaudited accounts, business premises evidence, contracts with clients, invoices, HMRC registrations and proof of PAYE systems.

However, the guidance never previously explained what level of commercial activity was sufficient, or what evidence would satisfy this requirement in practice. This left questions regarding whether dormant or newly incorporated companies could qualify, and whether pre-revenue businesses met the requirement.

In many sponsor licence applications, particularly for start-ups, scale-ups and newly established UK entities, this lack of clarity created significant uncertainty. Applicants and advisers were frequently forced to infer the Home Office’s expectations from refusal decisions, sponsor compliance visit outcomes, anecdotal practice trends and evolving caseworker approaches. The result was inconsistency and unpredictability.

2. The New Definition of ‘Operating or Trading’ in Sponsor Guidance

The Home Office has now formally inserted a definition of “operating or trading” into the sponsor guidance glossary. The glossary itself was first introduced in March 2026 as part of a broader restructuring of the sponsor guidance framework. The Home Office stated that the glossary was intended to “centralise and consolidate definitions previously set out in Parts 1 to 3 of the sponsor guidance”. The addition of “operating or trading” reflects the Home Office’s continuing effort to codify sponsor compliance terminology.

The glossary states:

“Broadly, ‘trading’ can be taken to refer to operations of a commercial kind by which the trader provides to customers for reward some kind of goods or services.

‘Operating’ includes the activities of both:

• charities and other not-for-profit organisations where they are providing a service to clients, customers or service users
• businesses who are engaged in pre-trade activities with a view to commencing commercial trading activity (as defined above) in the foreseeable future”

The above definition effectively confirms that the Home Office now regards “operating or trading” as a defined compliance concept rather than a broad discretionary assessment. Importantly, the new wording formally expands the scope of organisations capable of satisfying the requirement and provides long-awaited clarity for charities, not-for-profit organisations, start-ups and pre-trading businesses.

The guidance now expressly recognises that an organisation does not necessarily need to be fully revenue-generating in order to qualify for a sponsor licence, provided it can demonstrate genuine operational activity and credible plans to commence commercial trading in the foreseeable future. This marks a significant shift away from the previous uncertainty, where sponsors and advisers were often left to infer the Home Office’s position from caseworker practice and refusal decisions.

3. Why This Change Matters for Skilled Worker Sponsors

1. It Addresses a Longstanding Area of Uncertainty

This is arguably the most important aspect of the change.

For years, sponsors and legal representatives were required to advise on a key sponsor licence eligibility requirement without any formal Home Office definition. The practical reality was that many applications succeeded or failed based on unwritten assumptions about what constituted sufficient trading activity.

The new definition finally gives businesses a clearer benchmark, greater predictability, improved transparency in decision-making and a more concrete basis on which to prepare sponsor licence applications. For immigration practitioners, this represents a significant shift away from “reading between the lines” of sponsor guidance.

2. It May Affect Start-Ups, Pre-Revenue Businesses and Newly Established Businesses

The change is particularly important for:

• start-ups;
• overseas businesses establishing a UK presence;
• pre-revenue businesses;
• early-stage technology companies; and
• newly incorporated entities seeking Skilled Worker licences.

Historically, many genuine businesses struggled to satisfy the Home Office that they were actively “trading”, especially where they were:

• in a preparatory growth phase;
• heavily investment-funded;
• not yet generating substantial revenue; or
• building operations before recruitment commenced.

The insertion of a formal definition may help clarify how such businesses will now be assessed.

Equally, however, it may signal stricter scrutiny of companies perceived to exist primarily for immigration purposes rather than genuine commercial activity.

3. It Strengthens the Home Office’s Compliance Framework

The Home Office has increasingly sought to frame sponsor compliance as an evidence-based regulatory system. The 2026 sponsor guidance updates have demonstrated a clear trend towards:

• increasingly prescriptive compliance requirements;
• centralised definitions;
• enhanced record-keeping duties;
• more structured enforcement mechanisms; and
• lower tolerance for ambiguity.

The addition of a defined “operating or trading” concept fits squarely within that broader direction of travel.

Importantly, the Home Office’s guidance, Sponsor guidance part 1: apply for a licence, has also been updated to provide concrete examples of circumstances in which the Home Office is likely to conclude that a business does not have a genuine operating or trading presence in the UK.

The revised guidance confirms that sponsor licence applicants must provide documentary evidence demonstrating that they are genuine organisations with an operating or trading presence in the UK, and warns that licences may be refused or revoked where such presence cannot be established.

Significantly, the Home Office has now expressly identified two examples of situations in which it is unlikely to accept that a business is genuinely trading.

1. The first concerns organisations with “no significant trade activity”, where there is little evidence of genuine commercial transactions with customers, clients or service users and where the organisation is funded primarily through investors or related entities rather than trading income.
2. The second concerns so-called “circular trading”, where invoices and contracts exist primarily between linked entities under common ownership or control, with little evidence of genuine external commercial activity. The guidance indicates that the Home Office may regard such arrangements as artificial structures designed primarily to facilitate sponsor licence acquisition rather than genuine business operations.

The significance of these changes is reinforced further by the introduction of a new mandatory revocation ground in Annex C1(oo) of the sponsor guidance. This permits the Home Office to revoke a sponsor licence where it has “reasonable grounds to believe or suspect that an organisation has been established, or exists mainly, to facilitate the entry or residence of a worker who would not otherwise have permission to work in the UK.”

Although the Home Office has long scrutinised the genuineness of sponsor organisations, the introduction of this express revocation ground represents a notable strengthening of the compliance framework. It suggests a growing policy focus on identifying businesses perceived to be operating primarily for immigration sponsorship purposes rather than genuine commercial activity. When read alongside the new examples concerning limited trading activity and “circular trading”, it is clear that the Home Office is placing increasing emphasis on commercial substance, operational credibility and demonstrable organisational genuineness.

These additions are particularly significant because they provide the clearest indication to date of the types of organisational structures and financial arrangements likely to trigger heightened scrutiny during sponsor licence assessments and compliance activity. The guidance also suggests a growing Home Office focus on the commercial substance of a business rather than simply the existence of corporate documentation or formal legal structures.

Sponsors should therefore expect the Home Office to apply increased scrutiny to their commercial activity, organisational genuineness and overall capability to comply with sponsor duties. In practice, this is likely to involve more detailed compliance visits, greater emphasis on documentary evidence and more rigorous assessments of whether a business is genuinely operating in a manner consistent with its sponsorship activities.

4. It Could Influence Sponsor Licence Refusals and Revocations

One of the most significant practical consequences of the change is that the new definition is likely to play an increasingly central role in sponsor licence refusal decisions. By formally defining the concept within the sponsor guidance framework, the Home Office is now in a stronger position to apply the requirement more consistently, justify adverse decisions by reference to published guidance and defend enforcement action. At the same time, greater clarity may also assist sponsors seeking to challenge irrational, inconsistent or improperly reasoned Home Office decision-making.

4. What Skilled Worker Sponsors Should Do Now

Businesses applying for a Skilled Worker sponsor licence should now carefully review whether they can clearly evidence genuine operational activity, commercial presence and organisational capability to comply with sponsor duties.

In practice, sponsors will need to demonstrate that they have genuine vacancies, appropriate HR and recruitment systems and, where applicable, lawful trading activity supported by robust documentary evidence. This is likely to be particularly important for newly established companies, businesses with limited trading history, organisations operating from shared or virtual premises, overseas entities establishing UK branches and companies applying shortly after incorporation.

Where a business is operational but not yet fully revenue-generating, a clear explanation and credible supporting evidence may become increasingly important in demonstrating that the organisation is genuinely operating with a view to commencing commercial trading activity.

Not necessarily. An organisation may be able to qualify if it can demonstrate genuine operational activity and credible plans to commence commercial trading in the foreseeable future.

Why is the new definition of “operating or trading” important?

The definition provides a clearer benchmark for sponsor licence applicants and may improve predictability in how the Home Office assesses whether an organisation has a genuine operating or trading presence in the UK.

How might the change affect start-ups and newly established businesses?

The definition may help clarify how start-ups, pre-revenue businesses and newly established UK entities are assessed, particularly where they are operational but not yet generating substantial revenue.

Can a sponsor licence be refused or revoked if a business is not genuinely operating or trading?

Yes. Licences may be refused or revoked where an operating or trading presence cannot be established.

What evidence should sponsor licence applicants prepare?

Applicants should be prepared to provide documentary evidence of genuine operational activity, commercial presence, HR and recruitment systems, genuine vacancies and, where applicable, lawful trading activity.1.
