You cannot change your company name yourself; the support team need to edit it on the admin side of the site. This is because we need to make some checks about your new company.
Please get in touch with support through your supplier account and ask for your company name to be changed, providing the following information:
The old company name
The new company name
A link to your new website / social media so we can verify the change
A new email address or updated contact details (if appropriate)
