The United Kingdom company law regulates corporations formed under the Companies Act 2006. Also governed by the Insolvency Act 1986, the UK Corporate Governance Code, European Union Directives and court cases, the company is the primary legal vehicle to organise and run business. Tracing their modern history to the late Industrial Revolution, public companies now employ more people and generate more of wealth in the United Kingdom economy than any other form of organisation. The United Kingdom was the first country to draft modern corporation statutes, where through a simple registration procedure any investors could incorporate, limit liability to their commercial creditors in the event of business insolvency, and where management was delegated to a centralised board of directors. An influential model within Europe, the Commonwealth and as an international standard setter, UK law has always given people broad freedom to design the internal company rules, so long as the mandatory minimum rights of investors under its legislation are complied with.

A corporation is an organization—usually a group of people or a company—authorized by the state to act as a single entity and recognized as such in law for certain purposes. Early incorporated entities were established by charter. Most jurisdictions now allow the creation of new corporations through registration. Corporations come in many different types but are usually divided by the law of the jurisdiction where they are chartered based on two aspects: whether they can issue stock, or whether they are formed to make a profit. Depending on the number of owners, a corporation can be classified as aggregate or sole.
