What is the definition of a limited company?

A private limited company is the most common form of UK company incorporation.

It is set up directly by registering the company with Companies House.

Being a director of a private limited company is different to being self-employed opens in new window or operating as a sole trader.

A director of a private limited company is considered an employee of the company and, in the event of a legal dispute or problems with debt, it is the private limited company itself that is sued or pursued rather than the directors.

This means if the company fails the director’s personal assets such as family home or savings are not at risk – unlike a sole trader, who is held personally accountable for any unpaid debts or legal bills arising from a dispute or insolvency.

The shareholder’s liability is limited to the shares they hold in the business – hence the ‘limited’ part of the business structure name.

To become a shareholder you must purchase one or more shares issued by the company and these are issued when you form the company with each share representing an equal percentage of the business.

Additional shares can be created and issued after the business is incorporated and the more shares you hold, the larger the percentage of the business you own.
