How to set up a limited company: step by step
You can set up a limited company yourself at Companies House, or have an accountant do it and structure it properly at the same time. Either way, these are the steps involved:
- Choose a company name that is not already taken and does not use a sensitive or restricted word.
- Appoint at least one director, who must be aged 16 or over, and decide who your shareholders are.
- Set your share capital: how many shares, their value and who holds them. Most small companies start with a single ordinary share worth £1.
- Work out your PSC register, meaning every person with significant control who owns more than 25% of the shares or voting rights.
- Pick the SIC code that describes what your company does, and choose a registered office address, which goes on the public record.
- Prepare your memorandum and articles of association, the documents that set out how the company is owned and run.
- Verify your identity. Since 18 November 2025 every director and person with significant control must verify their identity through GOV.UK One Login or an Authorised Corporate Service Provider.
- File the incorporation with Companies House. Digital applications cost £100 and are usually approved within 24 hours, after which you receive your certificate of incorporation and company number.
- Register for Corporation Tax with HMRC within three months of starting to trade, and set up PAYE or VAT if you need them.
