Public Limited Company (plc)

A 'plc' is now the standard form for a public company in the UK. It was introduced in the Companies Act 1980.

A public limited company is defined as one limited by shares or by guarantee, whose memorandum states that it is a public company and which has registered as such.

It is a legal requirement that the words public limited company or plc must follow the company's name. Only plcs may qualify for listing or trading on the Alternative Investments Market (AIM) or the London Stock Exchange.
