In many ways, a public limited company is similar to a private limited company. You’ll still be required to register with Companies House and your personal liability is limited. The main characteristic and advantage of a public limited company is that you can raise capital through external investors, in essence, offering shares in your company to the public. To set up a public limited Company you need to have at least seven shareholders. There is no limit on maximum number of members of a public limited company. A public limited company is stepping stone for getting your company listed on stock exchange.
