WHOIS is a global database that keeps a record of who owns and manages domain names. Unless you have BT Domain Shield your WHOIS details will be visible to the public on any WHOIS site. Please note that it's a requirement of domain ownership that your WHOIS details are correct.
If you wish to change your WHOIS information, please get in touch by clicking the contact us link on this page.
If you order a new .uk domain name from BT Business you'll be able to download a domain name certificate from your Nominet account. You'll be emailed details about this when you register the domain name.
