Do you own a .org.uk or co.uk domain? If so, you most likely will want to register the .UK domain name now or lose the rights for that domain name.
In June 2014 the .UK registry introduced .UK as a shorter alternative domain name to .co.uk or .org.uk. When this domain name was introduced any .co.uk or .org.uk registered domain would automatically gain the rights to their .UK domain name.
However in June 2019 this is all about to change. If you do not register your .UK domain name before June 2019, the rights for your .UK domain name will be up for grabs to anyone.
If you live outside the UK you cannot apply for a .UK domain, however if you do, you will want to register your .UK domain name before June 2019. After June 2019, If you own yourdomainname.co.uk but have not registered the rights to yourdomainname.uk, somebody can purchase the rights to yourdomainname.uk and legally compete for your traffic and customers.
