But here's the pain point most Indian businesses run into: they treat "branch office" as a settled decision rather than one option among several. That confusion leads to wrong documents, missed deadlines and compliance gaps that surface months later.
This guide walks through the UK branch registration process step-by-step, covering documents, costs, tax obligations and where a firm like VJM Global fits into the picture for Indian companies managing this from Noida, Mumbai, Bengaluru or anywhere else.
Key Takeaways
- A UK branch registers with Companies House via Form OS IN01 as an "Overseas Company," not a separate legal entity
- The Indian parent company stays fully liable for the branch's debts and obligations
- Registration must happen within one month of the UK establishment opening
- Total costs depend on translation, banking setup and compliance support
- Choose a UK subsidiary instead when you need liability protection
What Is a UK Branch Office and Who Can Open One
A UK branch is an extension of your Indian parent company. It has no separate legal identity, unlike a subsidiary, and it is not a representative office.
Here's the distinction that trips people up:
- Representative office – can't trade or sign contracts; limited to marketing and liaison work
- Branch office – can trade, sign contracts and hire staff, but liability flows back to the parent
- Subsidiary – a fully separate UK legal entity with its own liability shield
Companies House guidance confirms registration is only required where the overseas company has a genuine physical presence in the UK, such as an office or branch actively carrying on business. An occasional hotel room booking or an independent agent doesn't count on its own.
Any incorporated Indian company can register a UK branch (sole proprietorships and unincorporated bodies cannot). Non-residents can fully own and run it, with no UK residency requirement for owners or directors. For companies wanting to test UK demand before committing to a full subsidiary, a branch is generally the lower-commitment starting point.
Step-by-Step Process to Register a UK Branch
Six moving parts make up this process, and skipping the order usually causes delays.
Step 1-3: Documents, Representation and Filing
- Gather parent company documents – certificate of incorporation, Memorandum and Articles of Association, and latest financial statements. Non-English originals need certified translations, authenticated and signed by a notary or other authorised person.
- Appoint a UK-based authorised representative to accept service of documents and handle Companies House correspondence on your behalf.
- File Form OS IN01 within one month of the UK establishment opening. The filing fee is currently £124. All overseas-company directors also need identity verification via Form OS VS01.
Step 4-6: Tax, Banking and Ongoing Compliance
- Register with HMRC for Corporation Tax. A non-UK company with a UK branch pays Corporation Tax on profits from its UK activity. Add VAT if you exceed the threshold, and PAYE if you hire staff.
- Open a UK business bank account. Indian-owned entities often face enhanced KYC/AML checks. Banks may take 3-6 months to onboard and typically want beneficial-owner ID plus source-of-funds evidence (Oury Clark).
- Maintain ongoing compliance. Notify Companies House of changes within 21 days using Form OS CH01 (establishment changes) or OS CH02 (parent company changes). File parent company accounts using OS AA01 where required.
Miss step 3's deadline and you're looking at penalties before you've even started trading.
Documents and Costs Involved in UK Branch Registration
Before you file form OS IN01 with Companies House, gather:
- Certificate of incorporation for the parent company
- Articles of Association (or equivalent constitutional documents)
- Board resolution approving the UK branch
- Proof of UK establishment address
- Shareholder and ultimate beneficial owner (UBO) details
What It Actually Costs
| Item | Approximate Cost |
|---|---|
| OS IN01 registration | £124 |
| Overseas-company accounts processing | £110 |
| Certified translations | Varies by language and length |
| Registered office/agent service | Provider-dependent |
| Legal and compliance advisory | Varies by scope |
Note: Companies House fees are fixed and published. Translation, agent and advisory costs depend on your documentation and how much support you need. Budget separately for bank onboarding and annual compliance; those costs recur every year, not only at setup.
Branch vs Subsidiary vs Representative Office: Choosing the Right Structure
This is the decision most Indian companies should make before filing anything, not after.
Commercial scope:
- Branch — can trade and contract in the UK as an extension of the Indian parent
- Subsidiary — can trade as its own UK legal entity
- Representative office — liaison, marketing, or research only; cannot trade or earn UK revenue
Liability exposure:
- Branch and representative office → liability sits with the Indian parent
- Subsidiary → liability limited to the UK entity itself
Financial disclosure:
- A branch must file the parent company's accounts publicly (format follows the parent’s home-country disclosure rules), which some Indian boards prefer to avoid
- A subsidiary only files its own UK accounts, typically within nine months of its accounting reference date
If your board wants a lower public profile for the Indian parent, or you're planning long-term UK operations rather than a market test, a subsidiary usually makes more sense despite the extra setup work.
Tax, Employment and Compliance Considerations
Corporation Tax and Permanent Establishment
A UK branch triggers Corporation Tax on UK-sourced profits. HMRC's permanent establishment (PE) test looks at whether you have a fixed UK place of business or an agent with authority to conclude contracts on your behalf. Current non-ring-fence rates run 19% for profits under £50,000, rising to 25% above £250,000, with marginal relief in between, according to HMRC's Corporation Tax rates and allowances.
VAT and Payroll
Register for VAT once taxable turnover exceeds £90,000. If you're hiring UK staff, you'll need PAYE registration before the first payday and must handle employer National Insurance contributions. Hiring often includes moving people, not only running payroll. For transferring employees from India, the UK Expansion Worker visa covers setting up a branch that hasn't yet started trading in the UK, provided the worker is already a senior manager or specialist. Once trading begins, GOV.UK directs applicants to the Senior or Specialist Worker route instead.

Common Mistakes Indian Companies Make When Opening a UK Branch
These three mistakes show up repeatedly when Indian companies register a UK branch:
- Skipping the subsidiary comparison and treating “branch” as settled—liability implications often surface only after registration.
- Underestimating the parent-account link—UK branch filings tie directly to the Indian parent’s accounts and governance, so weak books in India appear in UK filings.
- Missing the one-month OS IN01 window and director identity checks, which triggers avoidable delays and penalties.
Frequently Asked Questions

Can an Indian company open a branch office abroad?
Yes, Indian companies can open branches abroad, including in the UK, subject to Companies House registration. Outward remittances and reporting must also comply with RBI/FEMA rules under the Overseas Investment Directions, 2022.
Can a foreigner open a business in the UK?
Yes. Non-residents, including Indian nationals and companies, can fully own and operate a UK business or branch. There's no UK residency requirement for directors, owners or shareholders.

Yes. Both UK companies and registered branches must maintain a UK registered or establishment address for receiving official correspondence from Companies House and HMRC.
How long does it take to register a UK branch?
Document preparation and translation can take a few weeks. Companies House processing is typically quick once filed correctly, but bank account approval often takes 3-6 months for foreign-owned applicants.
Is a UK branch or subsidiary better for an Indian company?
It depends on your liability tolerance, disclosure preferences and long-term plans. Branches suit short-term market testing; subsidiaries suit companies wanting liability protection and easier banking access for sustained UK operations.
