Company-registration paperwork depends on the entity, transaction and jurisdiction. Start with the registrar’s own forms or online service, checking that the version applies to the intended filing.

Companies House publishes filing forms and a fee schedule, while its certified-document guidance explains another category of paid service. Separate incorporation, later filings, extracts and certification when planning costs. Review the current official page immediately before submission, since amounts, delivery options and accepted filing channels can change independently of the general guidance in an informational article.
