Sign in using your Companies House account

You need your Companies House Single Service login details and the business authentication code to verify your identity.

Do you have Companies House Single Service login details and an authentication code?

Please note that older WebFiling and WebCHeck service login details will not work. Users should re-register for the Companies House Single Service to get new login details. This does not change your company authentication code (used to submit your Confirmation Statement through Webfiling), which remains valid for the new service.
