Limited companies have some advantages for people who want to run their own businesses rather than becoming sole traders or forming a partnership. One of the main advantages of a limited company is that liability for shareholders or owners is limited and personal assets are protected.

There are four main types of limited company:

Forming public and private limited companies

You must notify Companies House when setting up any type of limited company; this is known as incorporation. HMRC will be automatically notified too, ready for Corporation Tax.

You can outsource registering a limited company to a solicitor, accountant, or an agent who deals specifically with company formations. Companies House also has an online incorporation service.


Public limited company (PLC) Private limited company (Ltd)
A public limited company must have a minimum of £50,000 in share capital. No minimum share capital.
Can sell shares on the stock market to raise money for the company.
  • Not permitted to trade on stock market.
  • Can only sell or transfer shares privately.
Requires a qualified secretary and at least two directors, who are all different people.
  • Requires at least one individual to act as director, who must be at least 16 years old.
  • This person can also be the sole shareholder.
  • Doesn’t require a company secretary.


Both set ups are liable for Corporation Tax, which is payable on company profits. Directors are also required to register for Self Assessment, even if they only take a salary through the company.


Incorporating Limited Company Guide

Who are the owners in public and private limited companies?

Both private and public limited companies are owned by shareholders who make investments in the company. A public limited company requires a minimum amount of £50,000 as share capital, unlike a private company which has no minimum.

There are other compliance requirements for companies, too. For instance, public companies must display ‘PLC; after their name. Private ones must include ‘limited’ or ‘ltd’.

Liability in public companies versus private limited companies

The shareholders of both private and public limited companies are part owners of the company. But, a limited company exists in its own right, completely separate from the owner’s or shareholders’ finances. This means that the personal liability of the owners and shareholders is ‘limited’ (hence the name) to their investment.

If the company has debts, the shareholders and owners can’t be pursued beyond their investment in the company, protecting their personal assets. Creditors can only seize the company’s assets.

Selling ownership of a limited company

A private limited company can’t put shares up for public sale like a public limited company can. Instead, private companies sell or transfer shares through private sale or transfer.

Do public and private limited companies both submit accounts?

A public limited company must submit accounts within six months following its accounting year end. A private limited company can submit accounts up to nine months after the end of its accounting year.

When can my limited company start trading?

A private limited company can start trading straight after incorporation. Public limited companies must wait for a trading certificate before starting to trade.

Do I need to have annual general meetings (AGMs) for my limited company?

Private companies don’t need to schedule AGMs and regular meetings, whereas a public company must hold an annual general meeting.

Who can be an officer in a public or private limited company?

Generally, anyone can become a company director, although there are criteria to fulfil.

What are the advantages of forming a public limited company?

There are a number of advantages to consider for a public limited company. A public limited company may find it easier to raise capital, either from existing shareholders or new investors, as it can offer shares for sale to the public.

The shareholders of a public limited company also have greater freedom to buy or sell their shares. This also allows public companies to offer shares to other businesses that they want to acquire.
