Allocation of domain names
Allocations are on a strict first-come, first-served basis to qualified applicants. There are no territorial restrictions: applicants need not have any connection to the UK other than those outlined below for .ltd.uk and other restricted domains.
.co.uk is by far the most used of the domains, followed by .org.uk then .me.uk. .plc.uk and .ltd.uk are only rarely used. The number of new registrations for each of the different .uk domains on a month by month basis can be seen on the Nominet website (
www.nominet.org.uk/intelligence/statistics/registration/)
The intended restriction of .co.uk to companies is purely nominal; in practice it is open to any and all applicants. Likewise, whilst .org.uk is for organizations, there are no restrictions on registering domains. While .me.uk originally had no restrictions on registrants it has since been tightened up to require registrants to be natural persons (i.e. not companies, etc.).
However, registrants in .ltd.uk must be, and remain, private limited companies incorporated under the UK Companies Acts. In addition, names can only be registered if they correspond (in accordance with the algorithm in the rules of registration) with the exact company name, as recorded at the companies registry at Companies House. The same conditions apply for .plc.uk, but for public limited companies. Neither of these domains is widely used.
.net.uk is more open, but the Nominet regulations still mean that a registrant must be an ISP, or a similar body, and that the domain is not used for providing services to end-users. .nic.uk, however, is limited solely to domains operated by Nominet.
.ac.uk domains are intended for the use of higher education institutions (beyond compulsory education age), and are also used by some academic support bodies such as the Universities and Colleges Admissions Service (
www.ucas.ac.uk), public research establishments, and learned societies such as the Royal Society (royalsoc.ac.uk). Primary and secondary education uses .sch.uk.
