Short Answer
Not always.
A business group can lawfully use different companies for property ownership, staffing, licences, contracting and payment collection.
The problem arises when those roles do not match the way the business actually operates.
For each activity, the group should identify which company is the operator, licence holder, employer, customer contracting party, revenue recipient, tax-invoice issuer and owner or user of the premises and assets.
The goal is not to force every role into one company. It is to ensure the differences are deliberate, legally supportable and documented consistently.
Why This Matters
A group can look like one business to customers while the legal pieces sit in several companies.
One entity may own the premises, another hold the operating licence, another employ the staff, and another receive online payments.
That may be intentional. But it can also create hidden problems.
For example, revenue may be received by a company that is not the contracting party, employees may be instructed by a company that is not their employer, or an old group entity may continue holding a permit after operations have moved.
Typical Scenario
A group has expanded quickly and used different entities over time for property, staffing, licences, commercial contracts and payment channels.
Management thinks of the operation as one business.
A legal or regulatory review asks:
“Which company is actually operating this activity?”
There may be several answers depending on the legal issue.
Practical Analysis
01Start with functions, not company names.
Map who owns the premises, who contracts with customers, who delivers the service, who employs the staff, who holds the licence, who receives the money and who issues the tax invoice.
02Treat the licence holder as a separate legal role.
Sector laws often place duties on the licensed person or company. An internal agreement saying that another group entity “operates” the business does not automatically move the statutory licence.
03Keep employer identity separate.
The company directing day-to-day work may not always be the legal employer. That can matter for payroll, social security, employee transfer, termination and foreign-worker authorisations.
04Check the revenue and invoicing flow.
For value added tax, the entity making the taxable supply and issuing the tax invoice should be analysed together with the entity actually receiving the customer money.
A central payment solution should not accidentally create a revenue flow inconsistent with the contractual or regulatory structure.
05Use intercompany agreements to support the structure—not to rewrite reality.
Management agreements, staff secondments, leases and service agreements can be important, but they cannot simply override a statutory licence or employment relationship.
06Do not treat every mismatch as an offence.
Different entities performing different functions is not automatically unlawful. The task is to determine whether the distinction is intentional, documented and permitted under the relevant legal regime.
This mapping is particularly useful before a restructuring or sale. A group may discover that the entity being sold does not hold the licence, staff, bank settlement account or key contract needed to operate the business. Identifying those differences early allows the transaction team to decide whether rights should be transferred, left under an intercompany arrangement or treated as a closing condition.
What We Usually Look At
We review the asset owner, leaseholder, operating entity, licence holder, customer contracting party, employer and payroll entity, work-permit employer where relevant, payment account, tax-invoice issuer, insurance and key intercompany agreements.
Common Traps
Typical mistakes are assuming a common brand makes group companies interchangeable, fixing a licence without checking the revenue flow, moving operations but leaving employees or payments in the old entity, and using an intercompany agreement as if it cures every regulatory mismatch.
Practical Next Step
Create one entity-to-operation map:
activity → operator → licence holder → employer → contracting party → revenue recipient → tax-invoice issuer → asset owner
For each difference, ask:
“Is this intentional, documented and legally permitted?”
