Registering a foreign company in the UK is one of the most commercially powerful moves an international business can make, but the rules have changed significantly since 2025. This guide covers every route, requirement, and compliance obligation you need to know before filing with Companies House.
2026 Update: Mandatory identity verification for all UK company directors and Persons with Significant Control (PSCs) came into force on 18 November 2025 under the Economic Crime & Corporate Transparency Act 2023 (ECCTA). Non-compliance blocks registrations and can result in civil penalties of up to £5,000 per breach. This guide incorporates all current rules.

Can a Foreign Company Register in the UK?
Yes, and the process is more straightforward than most international founders expect. The United Kingdom imposes no residency requirements on company directors or shareholders. Under the Companies Act 2006, foreign nationals from any country in the world can incorporate a UK limited company or register a UK branch of their existing overseas business.
This openness is by design. The UK actively competes for foreign direct investment, and its corporate registration framework reflects that. As of 2026, the UK has trade agreements with more than 70 countries, a corporate tax rate of 19–25% depending on profit levels, and London remains one of the world’s most connected financial hubs.
However, “can” and “should” are different questions. Foreign company registration in the UK carries genuine obligations — from ongoing Companies House filings to HMRC tax registration, identity verification, and (in some cases) UK banking requirements. Getting the structure right from the outset matters far more than getting registered quickly.
Why Foreign Founders Choose the UK
- Internationally recognised legal system (English common law)
- No residency requirement for directors or shareholders
- Fast online incorporation — often same-day
- Competitive Corporation Tax: 19% (profits under £50,000) to 25% (profits over £250,000)
- Over 130 double taxation treaties — among the most extensive in the world
- Access to UK banking, payment processors, and global investors
- Credibility with UK and international clients
Two Routes: UK Subsidiary vs. UK Branch (Overseas Company)
Before registering anything, you must decide which legal structure suits your situation. The two primary routes for a foreign business entering the UK are a UK subsidiary (private limited company) or a UK branch (registered overseas company establishment). They are legally and commercially distinct, and the choice has material consequences for liability, tax, and ongoing compliance.
Option 1: UK Subsidiary (Private Limited Company)
A subsidiary is a brand-new UK company, incorporated under English, Scottish, or Northern Irish law, and owned by your overseas parent company. It is a separate legal entity from the parent. This is the most common and recommended route for most international founders.
- Liability protection: The parent company is not automatically liable for the subsidiary’s debts. The corporate veil protects the overseas parent from UK liabilities — provided the companies are genuinely separate in governance and finance.
- Tax: The subsidiary is subject to UK Corporation Tax on its UK profits, as a standalone UK entity. This is often more tax-efficient than operating as a branch.
- Perception: A UK Ltd is perceived as a proper, committed UK business. It signals long-term intent to UK clients, banks, and investors.
- Cost to register: As little as £50 directly through Companies House, or £149–£549 via a formation agent with bundled services.
Option 2: UK Branch (Overseas Company Registration)
If your overseas company already exists and you want to open a UK place of business without creating a separate legal entity, you can register the overseas company as a UK establishment with Companies House. This is governed by the Overseas Companies Regulations 2009.
- No separate legal entity: The UK branch is legally part of your overseas company. All liabilities from UK operations attach directly to the overseas parent.
- Filing requirement: You must register with Companies House within one month of opening your UK establishment, using Form OS IN01 (registration fee: £124).
- Tax exposure: Branches can create permanent establishment (PE) risk, potentially exposing overseas profits to UK Corporation Tax. This requires careful tax structuring.
- Ongoing disclosure: Annual accounts of the overseas parent (in translated form if not in English) must be filed with Companies House — a significant disclosure obligation.
| Factor | UK Subsidiary (Ltd) | UK Branch (Overseas) |
| Separate legal entity? | ✅ Yes | ❌ No |
| Parent liability for UK debts | Limited (veil protects parent) | Unlimited (parent is responsible) |
| Registration fee | From £50 | £124 (Form OS IN01) |
| Registration deadline | No deadline (new entity) | Within 1 month of opening |
| Annual filing (UK accounts) | UK accounts only | Parent’s accounts (translated) |
| Tax treatment | UK Corporation Tax on UK profits | UK tax on UK branch profits; PE risk on wider group |
| Best suited for | Most international founders; e-commerce; startups; subsidiaries of MNCs | Large multinationals testing the market; temporary projects; professional services |
Verdict for most foreign founders: A UK private limited company (subsidiary) is the right structure. It offers cleaner liability protection, simpler ongoing compliance, and a more credible market presence. The branch route is typically used by large multinationals with specific reasons not to create a UK entity.
Step-by-Step: How to Register a Foreign Company in the UK
The following steps apply to forming a UK private limited company (the most common route for foreign founders). Branch registration via Form OS IN01 follows a similar but distinct process noted separately below.
1
Choose and Check Your Company Name
Your company name must be unique and not identical (or confusingly similar) to an existing registered name. If registering as a limited company, the name must end in “Limited” or “Ltd” (or the Welsh equivalents “Cyfyngedig” / “Cyf” for Welsh registrations). Sensitive or restricted words (e.g. “Royal”, “Bank”, “Insurance”) require additional approval.
Use the Companies House name availability checker at find-and-update.company-information.service.gov.uk before proceeding. Consider also checking the UK Intellectual Property Office (IPO) trade mark register if you intend to trade under the name.
2
Secure a UK Registered Office Address
Every UK company must have a physical registered office address in the same country where it is registered (England & Wales, Scotland, or Northern Ireland). A PO box alone is not accepted, HMRC requires a real street address. This is where official correspondence from Companies House and HMRC will be sent, and it appears on the public register.
Non-resident founders typically use a virtual office or registered address service in London or another UK city. These are legitimate, widely used, and cost between £50–£150 per year. Providers like 1Office, Hoxton Mix, or London Registered Office Address services are popular options.
3
Complete Identity Verification (2025–2026 ECCTA Rule — Critical)
Since 18 November 2025, all new UK company directors and Persons with Significant Control (PSCs) must verify their identity before their appointment can be registered at Companies House. This is the most significant change affecting foreign founders in recent years.
Identity verification can be completed in two ways:
- Direct via GOV.UK One Login — free, online, typically takes minutes. Requires a biometric passport or UK driving licence.
- Via an Authorised Corporate Service Provider (ACSP) — a regulated formation agent or company secretary who verifies your identity on your behalf. Preferred for overseas directors who do not hold UK-compatible ID documents.
Existing directors (appointed before 18 November 2025) have until 18 November 2026 to complete verification — but in practice, you must verify before your next confirmation statement is due.
4
Appoint Directors and Shareholders
A UK Ltd requires a minimum of one director (individual, aged 16+) and one shareholder (can be the same person, and can be a foreign national). There is no maximum on the number of directors or shareholders, and none need to be UK residents.
You must also identify Persons with Significant Control (PSCs) — anyone who owns more than 25% of shares, controls more than 25% of voting rights, or has other significant control over the company. PSC details are filed at Companies House and are on the public register.
Practical share structure tip: Start with 100 ordinary shares at £1 each (total paid-up capital: £100). This is far more flexible than the common “1 share at £1” approach, making it easier to issue shares to co-founders or investors later without share splits.
5
Prepare Constitutional Documents
Two documents are required on incorporation:
- Memorandum of Association: A legal statement confirming the formation of the company and the agreement of initial shareholders to create it. This document cannot be changed after registration.
- Articles of Association: The rules governing how the company operates — decision-making, director responsibilities, dividend rights, and share transfer procedures. You can use the standard Model Articles (simpler and fastest) or custom articles tailored to your specific needs.
6
File with Companies House
Registration is done online via the Companies House Web Incorporation Service at www.gov.uk/limited-company-formation/register-your-company. The government fee is £50 for standard same-day electronic registration. Paper registration costs £71 and takes significantly longer.
Alternatively, a formation agent typically bundles registration, a registered office address, a service address for directors, and often the first confirmation statement for £149–£549, depending on the package. For non-residents unfamiliar with UK company law, using an agent reduces errors and delays.
Upon approval, you receive a Certificate of Incorporation — a PDF document confirming your company number, company name, and formation date. This is your proof of legal existence in the UK.
7
Register for Corporation Tax with HMRC
You must register your new company for Corporation Tax with HMRC within 3 months of starting to trade. Failure to register on time results in automatic penalties starting at £100. Register online at gov.uk/register-for-corporation-tax. You will need your company’s Unique Taxpayer Reference (UTR), which HMRC sends by post to your registered office a few weeks after incorporation.
For Overseas Branch Registration (Form OS IN01)
- File Form OS IN01 with Companies House within 1 month of opening your UK establishment
- Registration fee: £124
- Provide: registered office abroad, legal form, governing law, director details, constitutional documents (translated into English if not already)
- Annual filing obligation: submit Form OS VS01 and parent company’s accounts annually
Tax Obligations After Registration
Registration with Companies House is only the beginning. Once your UK company or branch is active, you face a set of ongoing tax obligations that must be managed carefully to avoid penalties.
Corporation Tax
UK companies pay Corporation Tax on their taxable profits. The current rates (2025/26) are:
| Profit Level | Corporation Tax Rate |
| Up to £50,000 | 19% (Small Profits Rate) |
| £50,001 – £250,000 | Marginal relief applies (effective rate between 19%–25%) |
| Over £250,000 | 25% (Main Rate) |
Your Corporation Tax return (Form CT600) is due 12 months after your company’s accounting year-end. The tax payment itself is due 9 months and 1 day after the year-end. From 2026, Corporation Tax returns must be filed using HMRC-approved Making Tax Digital (MTD) compatible software — paper and standard web filings are being phased out.
VAT (Value Added Tax)
VAT is one of the most commonly misunderstood obligations for foreign-founded UK companies. Here is what you need to know:
- UK-established companies: Must register for VAT if taxable turnover exceeds £90,000 in any rolling 12-month period. You have 30 days to register once the threshold is crossed.
- Non-established (overseas) companies: There is no minimum threshold. VAT registration is required immediately from the first taxable supply made in the UK. Even a single sale to a UK customer can create the obligation.
- Digital services: If your company provides digital services (SaaS, apps, e-books, online courses) to UK consumers, VAT registration is required from the first sale, regardless of turnover.
- Standard VAT rate: 20% on most goods and services. Reduced rate: 5%. Zero rate applies to certain categories.
⚠️ Critical for e-commerce and marketplace sellers: If you hold inventory in a UK warehouse or fulfilment centre (including Amazon FBA), you have a taxable presence from the day the stock arrives, even before your first sale. HMRC has significantly increased enforcement of overseas VAT non-compliance since 2024, and back-assessed VAT bills (plus penalties and interest) can rapidly erode margins. Register early.
Making Tax Digital (MTD)
From 2026, all UK companies with taxable turnover above £90,000 must maintain fully digital records and submit Corporation Tax and VAT returns through HMRC-approved MTD-compatible software. Records cannot be manually re-keyed at any point — there must be a continuous digital link from your transaction data to your submitted return. Paper filings for tax are effectively phased out. Ensure your accounting software (Xero, QuickBooks, FreeAgent, Sage) is MTD-compatible from day one.
UK Banking for Foreign-Founded Companies
One of the most practical challenges facing overseas founders is opening a UK business bank account. Traditional high-street banks (Barclays, HSBC, Lloyds, NatWest) often require an in-person appointment and extensive documentation — a genuine barrier for non-resident directors.
In 2026, however, this problem has been largely solved by financial technology. The following options are widely used by overseas founders:
| Provider | Type | Notes for Non-Residents |
| Wise Business | Fintech / EMI | Excellent for multi-currency; widely accepted for UK Ltd operations; fast online setup |
| Revolut Business | Fintech / EMI | Popular with startups; supports 30+ currencies; physical debit card |
| Tide | Business Bank | UK-focused; integrates with accounting software; no minimum balance |
| Monzo Business | Business Bank | UK-regulated; requires director to have UK phone number |
| Barclays / HSBC | Traditional Bank | Available but may require in-person KYC; slower setup; greater credibility with certain clients |
Note: An e-money institution (EMI) account like Wise or Revolut is a real, functional business account for most operational purposes — receiving payments, paying suppliers, payroll — but is not a fully regulated bank account and does not offer FSCS protection. For companies where bank credibility matters (e.g. raising investment, government contracts), a traditional bank relationship is advisable.
Ongoing Compliance Obligations
Registration is a one-time event. Compliance is ongoing. Non-compliance with UK statutory filing requirements can result in automatic fines, director liability, and ultimately the striking-off of your company from the register — erasing the entity and any assets held in its name.
Annual Confirmation Statement
Every UK company must file an annual Confirmation Statement (formerly the Annual Return) with Companies House, confirming that the company’s registered information is accurate and up to date. Fee: £34 (electronic). Due within 14 days of the anniversary of incorporation (or the previous confirmation statement). Late filing is a criminal offence for directors.
Annual Accounts
Companies must prepare and file annual accounts with Companies House. The deadline is typically 9 months after the company’s financial year-end for private companies. Small companies may file abridged (simplified) accounts. Micro-entities have even simpler requirements. From 2026, filing must be done using approved software.
Director and PSC Changes
Any changes to directors or PSCs must be reported to Companies House within 14 days of the change. From 18 November 2025, new directors must have completed identity verification before their appointment can be registered. Failure to report changes on time is a civil and potentially criminal matter.
Common Mistakes Foreign Founders Make
- Using a foreign address as the registered office. This causes the incorporation to be rejected. Your registered office must be a real UK street address in the same jurisdiction (England & Wales, Scotland, or Northern Ireland) as your registration.
- Ignoring identity verification. Since November 2025, failing to verify your identity as a director or PSC blocks filings and can result in penalties of up to £5,000 per breach.
- Missing the Corporation Tax registration deadline. You must register within 3 months of starting to trade. The clock starts from the first commercial activity — not from when you receive your UTR.
- Treating a branch as a low-liability option. It is not. A branch means the parent company carries unlimited liability for the UK establishment’s activities.
- Starting with 1 share worth £1. This creates unnecessary friction when issuing shares later. Use 100 ordinary shares at £1 each (£100 paid-up capital) as your baseline structure.
- Not separating business and personal finances. Mixing company and personal money creates accounting problems, complicates tax filings, and can pierce the corporate veil in serious cases.
- Assuming VAT only applies once you’re profitable. VAT is triggered by taxable supplies, not by profit. A company in its first month of trading can be legally required to be VAT-registered.
Frequently Asked Questions
The following questions reflect the most common queries from foreign founders researching UK company registration. These are also structured for FAQPage schema markup to improve Google rich result eligibility.
Can a foreign national be the sole director and shareholder of a UK company?
Yes. The Companies Act 2006 imposes no residency or nationality requirement on directors or shareholders. A single foreign national can be the sole director and sole shareholder of a UK private limited company. The only requirements are that the director is an individual aged 16 or over, is not bankrupt, and is not disqualified from acting as a director in the UK. Since November 2025, identity verification is also required before the appointment can be registered.
Do I need to live in the UK to run a UK company?
No. You are not required to live in or even visit the UK to operate a UK limited company. The registration process is entirely online. You will, however, need a UK registered office address (a real street address, not a PO box), and you should be mindful that if the company is genuinely managed and controlled from outside the UK, HMRC may consider it non-UK tax resident — with different tax implications. Seek professional advice if central management and control will sit outside the UK.
How long does UK company registration take?
Standard online registration with Companies House typically takes between a few hours and 24 hours. Same-day electronic incorporation is available. Identity verification for new directors must be completed before the appointment is accepted, but via GOV.UK One Login this typically takes minutes if you have a biometric passport. Paper registration can take several weeks and is increasingly discouraged as Making Tax Digital rules phase out paper filings.
What is the difference between a UK branch and a UK subsidiary?
A UK subsidiary is a new, separate UK legal entity owned by your overseas parent company. It provides liability protection — the parent is generally not responsible for the subsidiary’s debts. A UK branch is not a separate entity; it is an extension of your overseas company into the UK, meaning the parent carries full liability for the branch’s activities. For most foreign founders, a subsidiary (UK Ltd) is the better route.
Does registering a UK company give me the right to live and work in the UK?
No. Incorporating a UK company does not grant any immigration rights. If you wish to live or work in the UK, you will need a separate visa — such as the Innovator Founder Visa (for new, scalable businesses), the Skilled Worker Visa (if your company employs you in a qualifying role), or another relevant category. Company registration and immigration are entirely separate legal processes.
What are the ongoing annual costs of running a UK company?
Minimum ongoing costs typically include: annual Confirmation Statement (£34), registered office address service (£50–£150/year), and accountancy fees for annual accounts and Corporation Tax return (£500–£2,000+/year depending on complexity). If VAT-registered, quarterly VAT return preparation adds to accountancy costs. These figures apply to a simple, straightforward trading company — more complex structures cost more. Total minimum annual running cost for a dormant or simple company: approximately £600–£800/year.
What is the identity verification requirement introduced in 2025?
Under the Economic Crime & Corporate Transparency Act 2023 (ECCTA), mandatory identity verification for all UK company directors and PSCs came into force on 18 November 2025. New directors must verify their identity before their appointment can be registered with Companies House. Verification is done either directly through GOV.UK One Login (using a biometric passport or UK driving licence) or via an Authorised Corporate Service Provider (ACSP). Existing directors appointed before 18 November 2025 have until 18 November 2026 to comply. Non-compliance blocks future filings and can result in penalties of up to £5,000 per breach.
Final Thoughts: Getting Your UK Registration Right
Foreign company registration in the UK has never been more accessible or more regulated. The combination of fully online incorporation, no residency requirements, and a globally respected legal system makes the UK a natural first choice for international founders. But the 2025–2026 reforms under the Economic Crime & Corporate Transparency Act have raised the compliance bar significantly.
The three decisions that matter most before you file:
- Structure: UK subsidiary (recommended for most) or overseas branch. Get this wrong and the liability consequences are significant.
- Identity verification: Complete this before attempting to register. Overseas directors should use an Authorised Corporate Service Provider (ACSP) to avoid delays.
- Tax registration: Register for Corporation Tax within 3 months of starting to trade. Assess VAT obligations immediately — the nil threshold for non-established companies means even your first UK sale may trigger a registration requirement.
Done correctly, a UK company is one of the most commercially powerful tools an international business can have. Done carelessly, it creates regulatory exposure that can far outweigh the cost of professional advice upfront.
