Private Limited Company (Ltd)
The most common company type in the UK by far. A private limited company has shareholders whose liability is limited to the value of their shares. Key features:
- Must have at least one director and one shareholder (can be the same person)
- Cannot offer shares to the public
- Must file annual accounts and a confirmation statement with Companies House
- Profits are subject to Corporation Tax (currently 19-25%)
- The company name must end with "Limited" or "Ltd"
This is the structure used by most small and medium businesses in the UK, from one-person IT contractors to large private companies like Dyson.
Public Limited Company (PLC)
A public limited company can offer its shares to the public and can be listed on the stock exchange. Requirements are more stringent:
- Minimum share capital of £50,000 (at least 25% paid up)
- Must have at least two directors and a company secretary
- Accounts must be filed within 6 months (vs 9 months for private companies)
- Must hold an Annual General Meeting (AGM)
- Subject to more detailed financial reporting requirements
Examples: Tesco PLC, BP PLC, Barclays PLC. Not all PLCs are listed on the stock exchange — "PLC" simply means they can offer shares publicly.
Limited Liability Partnership (LLP)
An LLP combines the flexibility of a partnership with limited liability for its members. Popular with professional services firms:
- Must have at least two designated members
- Members' liability is limited to their capital contribution
- Profits are taxed as personal income of the members (not Corporation Tax)
- Must file accounts and an annual confirmation statement
- Commonly used by law firms, accountancy practices, and consultancies
Community Interest Company (CIC)
A CIC is a special type of limited company designed for social enterprises that want to use their profits for the public good. Features:
- Must pass the "community interest test"
- Has an "asset lock" — profits and assets must be used for community benefit
- Regulated by the CIC Regulator
- Can be limited by shares or by guarantee
- Dividends are capped (if limited by shares)
Company Limited by Guarantee
Instead of shareholders, these companies have members who guarantee a nominal amount (often £1) if the company is wound up. Used by:
- Charities and non-profits
- Membership organisations
- Sports clubs and community groups
- Professional associations
They don't have share capital and typically don't distribute profits.
Charitable Incorporated Organisation (CIO)
A CIO is a legal form designed specifically for charities. Unlike a charitable company limited by guarantee, a CIO only needs to register with the Charity Commission (not Companies House for smaller CIOs). Benefits:
- Limited liability for trustees
- Less regulatory burden than a charitable company
- Can own property and enter contracts in its own name
Sole Trader
A sole trader is NOT a company — it's an individual trading in their own name. They don't appear on Companies House. Key differences:
- No limited liability — the individual is personally liable for all debts
- No filing requirements with Companies House
- Must register with HMRC for Self Assessment
- Profits taxed as personal income
If someone claims to be a "company" but doesn't appear on Companies House, they may be a sole trader (which is legitimate but offers you less protection).
