Crear una empresa en el Reino Unido

Cómo constituir una sociedad limitada en Inglaterra y Gales.

Visión general

Incorporating a company creates a separate legal entity with its own rights and liabilities, distinct from its shareholders and directors (Salomon v A Salomon & Co Ltd [1897]). Most UK businesses incorporate as private companies limited by shares (Ltd). The Companies Act 2006 is the principal legislation. Incorporation is done through Companies House, either online (same-day incorporation) or by post. Once incorporated, the company must comply with ongoing filing and reporting obligations.

Proceso paso a paso

1

Choose Company Name and Type

Select a unique company name that complies with naming rules. Check availability on the Companies House name availability checker. Choose company type: most businesses choose 'private company limited by shares'.

Plazo: 1–2 days
Consejos prácticos
  • Names must end with 'Limited' or 'Ltd' (or Welsh equivalent)
  • Cannot use names that are offensive, suggest government connection, or are too similar to existing companies
  • Consider trademark searching your company name
2

Prepare Formation Documents

Prepare: Memorandum of Association (statement that subscribers wish to form a company), Articles of Association (company constitution — most companies adopt the Model Articles), details of directors and secretary (if any), registered office address, and statement of capital/initial shareholdings.

Plazo: 1–2 days
Consejos prácticos
  • Model Articles are suitable for most small companies
  • You need at least one director (who must be a natural person)
  • A company secretary is optional for private companies
3

Register with Companies House

Submit formation documents online at Companies House or by post. Online incorporation costs £12 and is usually completed within 24 hours. Paper applications cost £40 and take 8–10 days.

Plazo: 24 hours (online) to 10 days (paper)
Consejos prácticos
  • Online is faster and cheaper
  • You receive a Certificate of Incorporation with your company number
  • The company legally exists from the date on the certificate

Set Up Business Operations

After incorporation: register for Corporation Tax with HMRC (within 3 months), open a business bank account, register for VAT if turnover exceeds £90,000, set up PAYE if employing staff, and arrange business insurance.

Plazo: 1–4 weeks
Consejos prácticos
  • Register for Corporation Tax online through the Gov.uk portal
  • You must file a Confirmation Statement (annual return) every year
  • First accounts must be filed within 21 months of incorporation

Advertencias importantes

Directors owe legal duties to the company under the Companies Act 2006 (ss.171–177), including duties to promote the success of the company, avoid conflicts of interest, and exercise reasonable care.

Failure to file accounts and confirmation statements on time results in automatic penalties and can lead to the company being struck off.

Directors can be personally liable for company debts in cases of wrongful trading (Insolvency Act 1986, s.214) or fraudulent trading (s.213).
