To be a plc (Public Limited Company), the company's constitution must state that it is such, specifically expressing the words 'Public Limited Company'. There are additional requirements for a plc (Public Limited Company) in comparison to a private limited company. Notably, the company must have a minimum share capital of £50,000, of which, at least £12,500 must be 'paid up' into the company's capital account. The company secretary must also be a suitably qualified person to act for a plc (Public Limited Company).
