Do You Need a UK Company to Bid for UK Public Contracts?

An overseas business finds a promising UK public-sector opportunity. Its experience matches the specification, the contract supports its growth plans and the team believes it can compete.

There is just one concern: the supplier does not have a UK company, office or bank account.

In most cases, forming a UK company is not a universal requirement for submitting a public-sector tender. Overseas organisations can often register and bid through their existing legal entity.

However, being able to submit a bid is not the same as being ready to deliver the contract. Local employees, premises, professional licences, insurance or tax arrangements may still be needed before contract award or mobilisation.

The key is to separate two questions:

1. Can our existing organisation participate in this procurement?
2. Can it sign and deliver the contract under the proposed operating model?

Can an Overseas Company Bid Directly?

The UK generally operates an open public procurement regime. Subject to the rules concerning excluded suppliers and any restrictions in the particular procurement, contracting authorities should generally accept requests and tenders from UK and overseas suppliers.

An overseas supplier can register its organisation on Find a Tender using a non-UK address and an overseas registration identifier. Where no suitable registration number applies, the platform can generate a unique identifier during the registration process.

The organisation registered should normally be the legal entity that will:

• Submit the tender
• Provide the financial information
• Rely on the stated experience
• Sign the resulting contract
• Invoice the buyer
• Accept contractual liability

Overseas suppliers can search UK public sector opportunities before deciding whether a subsidiary, branch or local delivery partner is commercially necessary.

Find a Tender registration does not confirm that the organisation is eligible for every procurement. Each opportunity may contain different participation conditions, regulatory requirements and service-delivery obligations.

What Is a Treaty-State Supplier?

The Procurement Act 2023 defines a treaty-state supplier as a supplier entitled to the benefits of an international agreement listed within Schedule 9 of the Act.

For a procurement covered by the relevant agreement, the contracting authority must not treat that supplier less favourably because of its association with the treaty state or its lack of association with the UK. Treaty-state suppliers also have access to the remedies provided by the Act for covered procurements.

Treaty coverage can depend on:

• The supplier’s country
• The public body conducting the procurement
• The estimated contract value
• The type of goods, services or works
• The sector
• Exclusions within the relevant agreement

Treaty-state status is therefore not a blanket approval applying to every UK public contract.

The same supplier may be protected in one procurement but outside the scope of the relevant agreement in another. Suppliers should check the specific coverage rather than relying only on their country’s general trading relationship with the UK.

The Act permits buyers to disregard tenders from suppliers that are not treaty-state suppliers in certain circumstances. Current government guidance nevertheless states that the UK generally supports open competition and advises buyers to think carefully before excluding an overseas supplier for that reason.

Which UK Procurement Rules Apply?

The Procurement Act 2023 is the main procurement regime for covered contracts in England, Wales and Northern Ireland.

Its application in Scotland is more limited. Most procurement by devolved Scottish public bodies continues under separate Scottish procurement legislation and is commonly advertised through Public Contracts Scotland.

International suppliers should establish:

• Where the contracting authority is based
• Which legislation is stated in the notice
• Which procurement portal is being used
• Whether sector-specific rules apply
• Whether the buyer is using a UK-wide framework

Do not assume that one successful registration or bid process will work identically across every UK jurisdiction.

Participation Conditions Must Relate to the Contract

A contracting authority can set conditions that suppliers must meet to receive the contract.

Under the Procurement Act, conditions of participation may assess only the supplier’s:

• Legal and financial capacity
• Technical ability to perform the contract

Those conditions must be proportionate to the nature, complexity and cost of the requirement. They should be identified in the tender notice, with further detail provided in the tender documents where necessary.

A buyer might assess whether an overseas supplier has:

• Suitable financial standing
• Required insurance
• Relevant contract experience
• Qualified employees
• Professional registrations
• Information-security controls
• Necessary equipment
• Appropriate licences
• Capacity to meet local response times

A requirement for UK resources or establishment should therefore relate to a genuine legal or delivery need, rather than simply reflecting a general preference for domestic suppliers where non-discrimination obligations apply.

Check when each requirement must be satisfied. Some apply when the tender is submitted, while others may need to be in place before award or service commencement.

Do not assume that you can create a UK operation after winning unless the procurement documents expressly allow that approach.

Bidding From Overseas Versus Operating in the UK

The distinction becomes clearer when bidding and delivery activities are considered separately.

This is a general guide rather than legal, tax or regulatory advice. The correct arrangement depends on the supplier, service and contract.

When Must an Overseas Company Register in the UK?

Conducting business with UK customers does not automatically mean an overseas company must register with Companies House.

Companies House guidance states that registration is generally required when an overseas company establishes a physical presence in the UK, such as a place of business or branch from which it carries on business. The UK establishment must normally be registered within one month of opening.

An overseas supplier might choose from several operating structures.

Contract Directly From Overseas

The buyer contracts with the supplier’s existing foreign legal entity.

This may suit services that can be delivered remotely or through short-term visits, subject to tax, immigration, regulatory and contractual considerations.

Establish a UK Subsidiary

A subsidiary is a separate UK-incorporated company.

Reasons for using one may include:

• Employing a permanent local team
• Separating UK contractual liabilities
• Establishing a local commercial presence
• Managing several UK customers
• Developing a UK credit and trading history

The subsidiary would need its own evidence and financial position assessed unless the tender permits reliance on the wider group.

Register a UK Establishment

The overseas company operates through a physical UK branch or place of business while remaining the contracting legal entity.

This creates Companies House filing and disclosure obligations, but it does not create a legally separate subsidiary.

Work With a UK Delivery Partner

The overseas supplier may use a subcontractor, consortium member or joint-venture partner to provide local capacity.

The bid should explain the responsibilities, contractual relationships and controls clearly. A buyer will want to know which organisation remains accountable for performance.

When Might a Local Presence Be Necessary?

A UK company may not be required to submit the bid, but a local operating presence may be needed where delivery involves:

• Regular on-site services
• Short emergency response times
• UK-based customer support
• Local warehousing or inventory
• Maintenance engineers
• Security-cleared employees
• Regulated clinical or professional activity
• Large-scale local recruitment
• Continuous access to public buildings
• Face-to-face contract management

A cloud software provider might be able to contract and deliver from overseas, provided its security, data and support arrangements satisfy the buyer.

A facilities-management supplier responsible for multiple public buildings is more likely to need UK employees, approved subcontractors, equipment and local supervision.

The proposed operating model should be decided before the tender is written. A promise of nationwide or round-the-clock coverage is only credible when the supplier can explain who will provide it and from where.

Check Regulation, Tax and Insurance Early

Local incorporation is only one part of the readiness assessment.

Sector Regulation

Some services require UK registration, authorisation or recognised qualifications.

This can affect sectors including:

• Healthcare
• Financial services
• Construction
• Security
• Transport
• Education
• Regulated professional services

The procurement documents may require evidence at tender stage or allow it to be completed before mobilisation.

Tax and VAT

The tax treatment of an overseas supplier depends on factors including its operating structure, the service provided and where the supply is treated as taking place.

A supplier should understand:

• VAT registration requirements
• Permanent-establishment risk
• Corporation or income-tax implications
• Payroll obligations
• Import duties where goods are involved
• Invoicing arrangements

Professional advice should be obtained before establishing a UK company or committing to a long-term delivery model.

Employment and Immigration

Overseas employees travelling to or working in the UK may require appropriate immigration permission. Local employment also creates payroll, pension, employment-law and workplace obligations.

Insurance

Existing insurance should be checked to confirm:

• UK activities are covered
• The bidding legal entity is insured
• Required limits can be provided
• Professional and public liability cover is suitable
• Any sector-specific requirements are included

Do not wait until contract award to discover that the insurer will not cover UK delivery or the required liability limits.

Can You Rely on Another Organisation?

A supplier may be permitted to rely on a parent company, subsidiary, consortium member or subcontractor when meeting participation conditions.

The tender may request:

• A formal commitment from the supporting organisation
• Details of the legal relationship
• Financial information
• Experience or case studies
• Exclusion declarations
• A parent-company guarantee
• Named delivery responsibilities

Current conditions-of-participation guidance recognises that suppliers may rely on other parties when demonstrating the capacity or ability required for a contract, subject to the buyer’s evidence and assessment requirements.

The bid should make clear which organisation will:

• Contract with the buyer
• Employ the delivery team
• Provide the relevant experience
• Supply equipment or technology
• Invoice for the work
• Accept liability
• Manage subcontractors

Vague references to “our international group” may not be sufficient.

Frameworks Require Their Own Assessment

Registration on Find a Tender does not appoint an overseas supplier to a framework or dynamic market.

Businesses pursuing framework agreements must still satisfy the arrangement’s participation conditions and complete its application process.

Framework documents may set requirements covering:

• Geographic service coverage
• Eligible supplier countries
• Local support
• Insurance
• Licensing
• Security
• Contracting entities
• Subcontracting
• Call-off delivery

A framework is itself a public contract, so conditions of participation may be used when suppliers apply for appointment.

Securing a framework position also does not usually guarantee revenue. Suppliers may need to compete for individual call-off contracts after appointment.

Review the Contract Before Restructuring the Business

The proposed contract can reveal whether direct overseas delivery is commercially realistic.

Review terms covering:

• Governing law and jurisdiction
• Currency
• Tax
• Payment
• Liability
• Insurance
• Data protection
• Intellectual property
• Audit rights
• Security
• Termination
• Subcontracting
• Dispute resolution

Where the procedure permits dialogue or changes to proposed terms, understand how bid negotiations must be managed.

Many public-sector tenders offer limited scope for negotiation after final submissions. Material concerns should be raised through formal clarifications at the stage allowed by the buyer.

Do not create a UK subsidiary purely to pursue an opportunity before understanding whether the contract’s liabilities, payment terms and likely return justify that investment.

Do You Need a UK Bank Account?

There is no universal requirement that every overseas public-sector supplier must have a UK bank account simply to submit a tender.

The contract and payment instructions should nevertheless be checked for:

• Accepted invoice currency
• Payment method
• Bank-verification requirements
• International transfer charges
• Foreign-exchange risk
• Electronic invoicing arrangements
• Tax deduction or withholding issues

A UK account may make some transactions easier, but it does not resolve wider questions about legal establishment, tax, insurance or regulated delivery.

Questions to Ask Before Forming a UK Company

Before incurring incorporation and operating costs, answer:

1. Can our existing legal entity enter the contract?
2. Does treaty-state protection apply to this procurement?
3. Does the tender expressly require UK establishment?
4. Can we meet every participation condition directly?
5. Will delivery require permanent UK employees or premises?
6. Are UK licences or professional registrations needed?
7. Does our insurance cover the proposed work?
8. Are the VAT and tax arrangements understood?
9. Could a delivery partner provide the local capability?
10. Does the contract value justify a permanent UK structure?

The answer may be different for each opportunity.

A small remote consultancy contract might be delivered directly by the overseas entity. A long-term national service contract may justify a subsidiary, branch or extensive partner network.

Monitor Opportunities That Fit Your Model

Effective monitoring of public sector opportunities should account for more than keywords.

Use filters and search strategies based on:

• Contract location
• Estimated value
• Required delivery model
• Buyer type
• Framework or direct-contract structure
• Mobilisation timetable
• Local response requirements
• Regulatory conditions

A remote-services supplier should not spend weeks assessing contracts that require permanent nationwide site coverage without a credible expansion or partnership plan.

A business actively entering the UK market may instead prioritise longer-term opportunities with enough value to support local investment.

Common Mistakes by Overseas Suppliers

International bidders should avoid:

• Forming a UK company before confirming it is necessary
• Assuming an overseas entity cannot participate
• Treating treaty-state status as universal approval
• Registering the wrong legal entity
• Relying on parent-company evidence without explaining the relationship
• Ignoring licences and professional regulation
• Leaving tax and insurance checks until award
• Promising local coverage without secured resources
• Assuming a framework guarantees revenue
• Overlooking governing law and liability
• Using a UK subcontractor without defining accountability
• Confusing eligibility to bid with readiness to mobilise

Make the Structure Fit the Contract

Overseas suppliers do not normally need to create a UK company simply to search for and submit public-sector tenders.

The more important question is whether the existing organisation can meet the participation conditions, sign the contract and deliver the requirement effectively.
