Domain Name Restrictions
Certain domain names have restrictions imposed by their registries. This means that they can only be used by specific people or companies, or for a specific purpose.
Please note the following restrictions that apply to certain domain names:
| .uk | .uk domain names are generally available on a first-come, first-served basis, subject to availability and Nominet's registration policies. The former reservation period for existing .co.uk and .org.uk registrants ended in 2019. |
|---|---|
| .me.uk | Are intended to be only used for personal usage, not commercial use. |
| .ltd.uk | Only Limited UK companies with a valid Companies House registration number. |
| .plc.uk | Only Publicly Limited UK companies with a valid Companies House registration No. |
| .net.uk | Only intended for NIC (Network Information Centre), NOC (Network Operations Centre), and other administrative use, and users are required to be Internet Service Providers (ISPs). |
Please also note the following general domain name restrictions:
- Each part of a domain name between dots can contain up to 63 characters. Registry-specific minimum and maximum lengths may also apply.
- Standard domain names use the letters 'a' to 'z', the numbers '0' to '9' and hyphens. Some extensions also support internationalised domain names.
- You can use a hyphen ("-") to separate words (example.com).
- Domains cannot begin or end with a hyphen, nor can they contain spaces or other punctuation.
- There are restrictions on minimum and maximum lengths.
- Domains are not case-sensitive; all domains are considered to be lowercase.
