Register a Company in the UK from Spain: Step by Step

Registering a company in the UK from Spain is a straightforward process for entrepreneurs and businesses looking to expand internationally. You don’t need to live in the UK to start a company there, but you do need to meet certain legal and administrative requirements. Here’s a step-by-step guide on how to register a company in the UK from Spain.

1. Define the Type of Business and Plan Accordingly

Before registering your company, research the UK market and assess whether your business idea is viable there. Think about your business model, define your target audience, and analyse the competition.

You’ll also need to decide on the type of company you want to set up — for example, a private limited company (LTD), a branch of a Spanish company, or another legal form.

2. Choose a Unique Company Name

Your company name must be unique and comply with the regulations set by Companies House, the UK’s official company register. 

Prepare at least three name options, as the name must not already be in use and must include the legal designation (e.g., LTD). Avoid restricted words like “Empire,” “Royal,” or “Bank”. Also, make sure to use only the Latin alphabet.

3. Provide a Registered Office Address in the UK

Every company registered in the UK needs to have a real, physical address in the country. This will be your company’s official address for all sorts of things, like receiving official letters. If you don’t have your own office in the UK, you can use a professional service provider that offers a registered address for this purpose.

4. Appoint Directors and Shareholders

To form a limited company, you must appoint at least one director, who must be an individual (not a company). There are no nationality or residency restrictions, so a Spanish citizen living in Spain may act as a director.

You also need at least one shareholder. This can be the same person as the director. The minimum share capital depends on the type of company, although many structures do not require a legal minimum.

5. Gather the necessary documents

To complete the registration process, you will need to gather the following documents and details:

• Completed application form
• Scanned copy of the director’s and shareholders’ passport or ID
• Proof of the directors’ addresses (such as a utility bill)
• Details of the share capital and how shares are divided
• Description of your business activities

You’ll also need to draft the company’s constitutional documents: the Memorandum of Association and Articles of Association, which outline the company’s structure and internal rules.

6. Submit the Application to Companies House

You can apply online through the Companies House website. The process usually takes between 3 and 10 working days. However, in some cases, it may be completed in under 24 hours, depending on the submission method and the complexity of the case. Once approved, Companies House assigns your company a unique registration number.

7. Open a Business Bank Account

After registeration, open a business bank account in the company’s name in the UK. This is essential for managing finances, receiving payments, and meeting tax obligations.

Some traditional banks require in-person visits to open an account. However many online banks—like Wise, Revolut Business, and Monzo—offer remote account opening options suitable for non-residents.

8. Register with HMRC for Tax Purposes

Finally, you’ll need to register your company with HM Revenue & Customs (HMRC), the UK’s tax authority, to ensure compliance with tax obligations. This includes registration for Corporation Tax and, if applicable, VAT and the PAYE system if the company employs staff.

HMRC registration must be completed within three months of starting business activity.

9. Deadlines and Ongoing Responsibilities

The typical timeframe for registering a UK company from Spain is 3 to 10 working days, depending on how quickly the required documents are submitted and verified. Opening a bank account can take longer—especially with traditional banks—so it’s advisable to begin that process as early as possible.

Ongoing responsibilities include filing annual accounts and tax returns on time. You must also keep Companies House and HMRC informed of any changes to directors, shareholders, or the registered office address.

10. Operating from Spain: Additional Considerations

Even if your company is registered in the UK, if it has operations or a presence in Spain, it must also comply with Spanish tax and commercial regulations. Ypu may need to register with the Spanish Commercial Registry and declare taxes in Spain for business activities carried out within the country, under the double taxation treaty.

In summary, registering a company in the UK from Spain is a relatively simple process if you follow the right steps and have your paperwork in order.
