Registrants who own an existing co.uk, org.uk, me.uk, net.uk, plc.uk or ltd.uk before Oct. 29, 2013 will have their .uk domain name reserved for free up until June 10, 2019, as long as the existing domain name remains registered.
For those who have the same name but different domain name endings -- like www.example.co.uk and www.example.org.uk -- can use the Rights lookup tool at www.dotuklaunch.co.uk website to find out who has the rights to the www.example.uk domain name.
