" uk Rights FAQs
Which domains are eligible for the rights to an equivalent .uk domain?
Domain names ending in .co.uk, .org.uk, .me.uk, .ltd.uk, .plc.uk and .net.uk are eligible, subject to the below criteria.
If your domain was registered before
23:59hrs on 28 October 2013 you will have the rights to the equivalent .uk domain, providing there was
no other corresponding .co.uk, .org.uk, me.uk, .ltd.uk, .plc.uk or .net.uk registered.
If there is a situation where there are two or more domains with the same website name, the .co.uk will be offered the .uk equivalent. Where there is no .co.uk, the .org.uk will be offered the .uk equivalent. Where there is no .co.uk or .org.uk the .me.uk will be offered the .uk equivalent.
Where a .co.uk domain has been registered after 28 October 2013 and before launch on 10 June 2014
the co.uk domain holder will also have rights to the .uk equivalent, as long as there is no ‘clash’ with any existing domains meeting the criteria above.
The current domains that are not eligible for this process are .sch.uk and those not managed by Nominet, such as .ac.uk, .mod.uk, and so on.
Are the rules of registration the same as those for existing .co.uk and .org.uk domains?
The rules are largely the same for existing .co.uk and .org.uk domains, with two exceptions:
- Where the registrant is overseas an address for service in the UK is required.
- PO Boxes are unacceptable in the address.
If a contested .org.uk and a .co.uk existed on the 28 October 2013 but between the launch date the .co.uk drops and is registered by someone else – who gets the right to the .uk?
The new .co.uk registrant gets the right to the new .uk equivalent domain.
What happens if a domain name with a right to the .uk equivalent expires or is cancelled on or after the launch date?
If your existing domain name was not registered on 10 June 2014 or has not been maintained since .uk launch you do not qualify.
If your existing domain name (
www.example.co.uk) is cancelled and deleted from the register, any right to the new .uk equivalent domain will have been lost and cannot be recovered. That includes .co.uk domains with rights.
What happens if I have the rights but do not want to register the domain name?
If your domain name is eligible for the .uk equivalent, but you don’t want to register it, no one else will be able to register it until
10 June 2019. After 10 June 2019, the domain will become available to anyone who wants to register it.
If you would like someone else to be able to buy the .uk domain name before the 10 June 2019 – for example you may have been asked if you would be interested in selling the domain name to another person or company – you can do this. You will need to register the .uk domain name yourself and then transfer the domain name to the third party.
