Principal contacts act as the main contact for any queries relating to an account.
To add or remove someone as a principal contact, please open the Account menu at the top of the screen, select Account details and then select manage users.
To edit the rights of an existing user select the yellow pencil next to their name and click edit user access.
The below permission is included as one of the options.
Note: You may indicate more than one user as a principal contact.
Note: Being a Principal contact isn't just a label: it also controls which users receive certain automatic email notifications, such as Companies House status-change emails (e.g. a company moving to "Active - proposal to strike off"). If a user isn't receiving these despite other notifications working fine, check they're ticked as a Principal contact.
You can also set this for yourself: open the Account menu at the top of the screen, select Profile, then select Edit your details and tick Principal contact.
