Your new WebFiling account will include improved security features and will give you more freedom to self-manage your account.
This is the first step in creating a single sign-in across all Companies House services.

Companies House will soon be introducing a new WebFiling account – GOV.UK

New benefits include:

• multi-factor authentication
• the ability to link your company to your WebFiling account to give you more control over your filings
• the ability to digitally authorise people to file on your behalf on WebFiling, and to remove authorisation
• easily seeing who’s digitally authorised to file for your company
• an option to sign up to emails to help you with the running of your company
