Whois Domain Registration Details
Whilst Law Enforcement can still request the WhoIs Registration details, due to the changes brought in with the adoption of the General Data Protection Regulation (GDPR) in May 2018, the publicly available WhoIs Registration Data has been removed by most providers. The best we can currently advise to use is at GoDaddy, who will return the WhoIs Registration details of sites if the registrant is outside of the EU;

godaddy.com


For a limited number of reasons you can obtain the withheld non-public data on a .uk domain name by completing the WhoIs Request form from the below link and then emailing it to Nominet Here. They do not charge for this service and aim to respond within a day, however be aware Nominet report that they will notify the registrant of your request and your details;
