The real costs, the details Companies House asks for, and how to make sure the name you file is one the register will accept.
Companies House charges £50 to incorporate online. A formation agent adds a fee from about £13 and in exchange prepares the filing, validates your details before submission, and typically bundles useful extras such as a registered office address so your home address stays off the public record. After incorporation, the recurring cost is the £34 annual confirmation statement.
Approval is fast: most online applications clear within 24 hours on working days, and often the same day you file.
Companies House is also rolling out identity verification for directors and people with significant control, so expect an ID step either at Companies House or through your formation agent.
A filing with a name that clashes with the register is rejected, and starting again costs you days. The register check is also not the whole picture: the strongest business names clear the domain registry and Companies House at the same time, so the brand, the website, and the legal entity all carry one name.
That is the check NameGenie runs while you are still choosing. Generate names and every suggestion arrives with its domain availability and an exact-match Companies House check, or see how the whole journey fits together on our start a business guide.
