How to Register a Limited Company in the UK (Step-by-Step Guide)

Setting up a limited company in the UK is one of the most effective ways to protect your personal assets, improve tax efficiency and strengthen your professional image. This guide explains each step of the formation process and highlights what new directors must know to stay compliant with UK law.

1. Choose a Unique Company Name

Your first step is selecting a company name that:

  • Is not already registered with Companies House
  • Is not offensive or misleading
  • Does not include restricted words without permission
  • Is distinct enough to avoid trademark disputes

Use the Companies House name availability checker before proceeding.

2. Decide Your Company Structure

Most new businesses register as a Private Company Limited by Shares (Ltd).
This structure offers:

  • Limited liability
  • The ability to take dividends
  • A professional appearance for clients

3. Appoint Directors and Shareholders

You must appoint at least:

  • One director
  • One shareholder (this can be the same person)
  • One person with significant control (PSC)

Directors are legally responsible for filing annual accounts and ensuring the company meets UK compliance rules.

4. Provide a Registered Office Address

Your company must have a registered address located in the UK.
All official HMRC and Companies House correspondence will be sent there. Many directors use their accountant’s address for privacy and convenience.

5. Prepare Your Company Documents

You must submit:

  • Memorandum of Association – confirms agreement to form the company
  • Articles of Association – outlines how the company will be run

Standard templates work for most businesses.

6. Complete Your Companies House Registration

Register online with Companies House.
Approval typically takes within 24 hours. You will receive:

  • Certificate of Incorporation
  • Company number
  • Confirmation of legal formation

7. Register for Corporation Tax

You must register for Corporation Tax within 3 months of starting to trade.
This is done through your HMRC business tax account.

Setting up a limited company is simple when you follow the correct steps. However, many new directors choose to work with an accountant to ensure full compliance with UK tax rules, VAT thresholds, PAYE obligations, and bookkeeping requirements.
