Registering a Company in the UK From Denmark: Subsidiaries & Structures

For Danish SaaS firms, design studios, green-tech ventures, and life-sciences businesses, the UK remains a practical first step outside Scandinavia. English is the operating language of the company register and of most international client contracts. London sits one hour behind Copenhagen, close enough for same-day calls with investors, agencies, and enterprise buyers. A UK Ltd gives Danish groups a familiar limited-liability vehicle that US and British procurement teams recognise without asking for exotic entity types.

The commercial case is not only market size. The UK is widely seen as one of the easier and lower-cost jurisdictions for forming a limited company, with a straightforward process for both residents and non-residents. FinTech and electronic-money providers commonly onboard non-resident directors from Denmark, issue UK IBANs, and connect to Stripe, PayPal, and similar rails that enterprise clients expect; for many founders, the country’s robust legal system and world-class financial services are also part of the appeal of starting a business in the UK. Minimum share capital for a private Ltd is £ 1, and private companies no longer require a company secretary by law.

That said, Brexit removed automatic EU passporting. A UK company does not grant access to the EU single market on Danish terms. Danish businesses serving EU clients often keep the Danish ApS or A/S as the EU hub and add the UK Ltd where British or English-speaking revenue justifies a separate entity. The structure should follow where contracts are signed, staff are hired, and profits are genuinely earned.

Before any filing, the legal relationship between Denmark and the UK entity must be clear. Three paths dominate, and they are not interchangeable.

UK Subsidiary

A UK subsidiary is a new private limited company incorporated at Companies House. The Danish ApS or A/S appears on the share register as corporate shareholder, often holding 100% of the shares. The subsidiary has its own directors, bank accounts, and tax filings. As the most common UK business structure, a private limited company gives shareholders limited liability, so UK debts and financial difficulties generally stay inside the subsidiary and help protect personal assets, which is why established Danish groups choose this route when hiring in London, signing UK client contracts, or ring-fencing commercial risk.

UK Branch

A UK branch (UK establishment) is not a separate company. It is an extension of the Danish parent registered under the Overseas Companies Regulations. The parent remains directly liable for branch obligations and must register within one month of opening a UK place of business. Branch registration suits light representative activity; it offers less liability separation than a subsidiary.

Standalone UK Ltd

A standalone UK Ltd suits individual Danish founders who are not yet operating through an ApS/A/S, or who are testing the market before the Danish company acquires the shares. There is no corporate parent on the cap table at incorporation, though shares can be transferred to a Danish company later with legal and stamp-duty review.

UK companies must maintain a public register of persons with significant control (PSCs) — anyone who holds more than 25% of shares or voting rights, can appoint or remove a majority of directors, or otherwise exercises significant influence over the company. For a Danish-owned subsidiary, the parent company typically appears on this register; for a standalone Ltd, individual founders are listed instead.

The Companies House registration process for a non-UK applicant is the same as for UK residents. A non-UK resident or foreign national can be a director, shareholder, or company secretary without being physically present in the UK. What differs for a subsidiary is who appears on the share register, how the Articles are drafted, and what corporate approvals the Danish parent passes before signing. Standard online applications are often approved within 24 hours on a business day; postal applications take 8 to 10 days and cost more.

1 Confirm Danish parent approvals

Before filing, the Danish ApS or A/S should pass a board or shareholder resolution authorising incorporation of the UK subsidiary, approving the proposed name and share capital, and naming who will sign incorporation documents on the parent's behalf. The parent will subscribe for shares in the new Ltd, so the signatory must have authority to commit the Danish company.

2 Choose a company name

Choose a unique company name that complies with Companies House rules: it must be distinct on the register, not misleading, and free of restricted words without permission. Private companies must normally end with “Limited” or “Ltd”. A trading name different from the registered name is permitted if branding requires it. Name approval is only one part of registration; at least one shareholder and a UK registered office address are also required.

3 Decide the jurisdiction of incorporation

A UK subsidiary must be incorporated in England and Wales, Scotland, or Northern Ireland. Each jurisdiction has its own legal system; a company registered in Scotland requires a Scottish registered office, and the same principle applies in Northern Ireland. Most Danish-owned subsidiaries targeting the broader UK market incorporate in England and Wales, but sector-specific or regional plans may justify Scotland or Northern Ireland.

4 Appoint a director and define shareholding

The subsidiary needs at least one natural-person director (16+) and at least one shareholder. For a wholly owned subsidiary, the shareholder is the Danish ApS or A/S. Where the structure allows, the same person may act as sole director and sole shareholder. Share capital can be minimal: a single £ 1 ordinary share held by the Danish parent is valid. Persons with significant control must be identified; a parent holding more than 25% of shares or voting rights is typically registrable as a corporate PSC.

Directors must provide a residential address for Companies House records and a service address for public correspondence. The residential address may be in Denmark; the public address is the director's service address, which is shown on the public register and used for official correspondence addressed to directors. Separately, non-residents still need a UK official company address for the company’s registered office, which can be a virtual office or the address of a trusted individual; this address is publicly visible on the Companies House register and receives correspondence from Companies House and HMRC.

5 Select a registered office and formation route

The registered office is the company’s business address for legal purposes and must be a real physical UK location; a PO Box alone is not sufficient, and Companies House requires an address that is publicly accessible. This address also receives statutory mail and other official post for the company. Many Danish groups use a formation agent or ACSP to provide a registered office, handle identity verification, speed up registration through electronic submission, and support key incorporation documents such as the memorandum and articles of association. DIY filing through Companies House WebFiling is possible but leaves non-residents to manage verification and address compliance directly, though online filing usually means there is no need to send physical documents.

6 Prepare constitutional documents

The memorandum of association is the legal statement by which the initial members, including the Danish parent, agree to form the company. The articles of association set internal rules on director appointment, share transfers, and dividends. Subsidiaries owned by a Danish parent often use bespoke Articles so the parent can control board composition and restrict share issues. Model Articles may suffice for standalone founder-led companies but are frequently too permissive for group structures. Direct filing costs the standard Companies House filing fee of £ 100, while non-residents often use agent packages starting from around £ 135 when extra services are included.

7 Submit the incorporation application

Online incorporation collects the same information as paper Form IN01: company name, registered office, director and PSC details, share capital, and SIC code describing the activity. On approval, Companies House issues a certificate of incorporation with the company number. Corporation Tax registration with HMRC is usually initiated as part of the online journey unless the company is dormant.

The subsidiary path fits when revenue already flows through a Danish ApS or A/S, UK clients require a local Ltd counterparty, the group plans to employ UK-based staff, or investors expect a formal UK entity in the structure. Subsidiary incorporation is the standard choice for Danish companies treating the UK as an operating market rather than a temporary sales outpost.

Nearly every Danish-owned UK subsidiary is a private company limited by shares (Ltd) under the Companies Act 2006, and for a new company it is the most common business structure in the UK. The Ltd company is a separate legal person. It can own assets, employ staff, enter contracts, and sue or be sued in its own name. Ownership sits in shares; the Danish parent, as sole shareholder, controls the subsidiary through voting rights and, where Articles permit, the right to appoint and remove directors.

At least one director must be a natural person aged 16 or over. That director may live in Denmark. Private companies cannot use a corporate entity as a director. The Danish ApS or A/S can, however, be the sole shareholder. A company secretary is optional for private companies, though some groups appoint one for governance hygiene.

Other UK structures rarely fit the subsidiary use case. A sole trader operates personally, must handle and pay income tax on profits, and remains personally liable for business debts. A general partnership involves two or more people sharing profits and responsibility. A limited liability partnership can suit certain professional firms, but it requires registration with Companies House and is usually governed by a written LLP agreement. Public limited companies (PLCs) are reserved for larger capital markets plans. For a Danish parent seeking liability separation, strong legal protection under UK law, and a standard contracting counterparty, the Ltd subsidiary is the default and correct choice.

Companies House will accept a well-formed application from Denmark in a day or two. What takes longer is aligning Danish and UK tax, governance, and group documentation. That work belongs before the first trade, not after a compliance reminder arrives.

UK tax residency is not the same as UK incorporation

Incorporating at Companies House does not automatically make the company UK tax-resident. HMRC generally tests central management and control: where strategic decisions on policy, finance, and major contracts are made and documented. A subsidiary with a UK registered office but board meetings held in Copenhagen may be non-resident for UK Corporation Tax if facts support that conclusion. Conversely, regular strategic decisions taken in the UK can create UK residence regardless of where the parent sits.

The UK–Denmark double taxation convention

The 1980 UK–Denmark double taxation convention, as amended and modified by the Multilateral Instrument, governs how income, dividends, and capital gains are taxed across the border. Where both countries treat the same company as resident, tie-breaker rules may require the competent authorities to agree on a single residence. Treaty relief on dividends and interest depends on meeting substance and documentation requirements, not only on having a certificate of incorporation.

Danish tax and corporate reporting

The Danish parent must reflect the UK subsidiary in group accounts and tax repTorting where consolidation rules apply. Transactions between Copenhagen and the UK entity — management charges, IP royalties, cost recharges, and loans — fall under transfer-pricing rules and must be documented at arm’s length. Skattestyrelsen (the Danish Tax Agency) expects the arrangement to reflect real functions and risks.

The parent’s CVR number with Erhvervsstyrelsen (the Danish Business Authority) does not change; the subsidiary receives its own Companies House number after incorporation. All UK businesses must also register with HMRC, manage their own tax obligations, and track tax returns by the UK tax year, which runs from 6 April to 5 April the following year.

Permanent establishment and UK substance

If the subsidiary hires UK staff, maintains a fixed place of business, or habitually concludes contracts in the UK, permanent establishment risk arises even when parent-level management stays in Denmark. Intercompany agreements should describe which entity performs which functions and at what price. A subsidiary that only exists on paper while all work is done in Denmark creates audit risk in both jurisdictions.

Identity verification under the Economic Crime and Corporate Transparency Act

All company directors and persons with significant control (PSCs) must verify their identity before or at incorporation, either through Companies House or an Authorised Corporate Service Provider (ACSP). From 18 November 2025, new directors must verify during appointment. Verified directors receive an 11-character Personal Code for future filings.

Danish directors usually verify via ACSPs, as direct online verification requires UK-specific ID not commonly held by Danish residents. Corporate PSC details must be filed alongside individual verifications.

A certificate of incorporation marks the start of compliance work, not the end. A Danish-owned subsidiary becomes operable only when banking, tax registration, group agreements, and statutory registers align with how the business will actually run.

Open a UK business bank account

A UK bank account is not required to register the company but is essential for client payments and payroll. Traditional banks often need UK ties or trading history, while FinTech banks onboard Danish non-resident directors faster and provide UK IBANs for Stripe and PayPal. Early account setup helps avoid delays in invoicing.

Providers usually require incorporation documents, proof of identity and address, a business plan or website, expected turnover, and UK activity details. A Danish multi-currency account may work for EU flows but is less convenient where UK account details are needed. Keep company accounts separate from personal bank accounts.

Register for Corporation Tax and other HMRC obligations

All UK companies must register for Corporation Tax within three months of starting business activity. Dormant companies follow separate rules but still have Companies House duties. UK-resident subsidiaries pay Corporation Tax on taxable profits at 19% where augmented profits are £ 50,000 or less, and at 25% where profits exceed £ 250,000, with marginal relief between those thresholds (GOV.UK Corporation Tax rates).

VAT registration becomes mandatory when taxable turnover exceeds £ 90,000 in a rolling 12-month period. PAYE registration is required once the subsidiary employs staff subject to UK payroll, including UK-based employees of an otherwise Denmark-managed group. Danish groups selling physical goods into the UK should plan separately for customs, import VAT, and post-Brexit shipping rules; company registration alone does not resolve product border compliance.

Put intercompany agreements in place

Before significant trading between Copenhagen and the UK entity, the group should document IP licence terms, management or service fees, cost recharges, and any intra-group loans at arm's-length prices. These agreements support transfer-pricing files in Denmark and explain profit allocation if HMRC or Skattestyrelsen (the Danish Tax Agency) reviews the structure. They also clarify which entity owns client relationships and which bears operational risk.

Maintain statutory records and filings

The subsidiary must maintain registers of directors, shareholders, and PSCs, keep minutes of board and shareholder decisions, preserve accounting records, and keep official company details up to date. Each year, annual accounts and a confirmation statement must be filed at Companies House even if profit is minimal or nil. Late filing attracts penalties and damages credibility with banks and clients.
