Upon completion of the incorporation process, Companies House issues a Certificate of Incorporation (referred to in the source as the registration document). This is the company's birth certificate, conclusively evidencing that the company has been legally formed. It sets out the company's registered name, its registered number, and the address of its registered office. The Articles of Association contain the internal rules, but the certificate is the primary legal document of formation. Under the Companies Act 2006, the Memorandum of Association is now a much simpler document of declaration and no longer sets out the objects clause in the same way it did historically. The Chairman's Statement is an optional narrative. This distinction is a core piece of The Insurance Company Environment knowledge, highlighting the formal documentation that underpins the existence of any UK-registered insurer, and is a prerequisite for all subsequent financial and statutory reporting, such as the obligation for a public limited company to file its accounts by 30 June.
