The UK Government manages the .gov.uk domain name registry in order to signify digital services that are part of the administration of the state, so that they can be identified as authoritative and trustworthy.
The rules governing which organisations are eligible to register .gov.uk domain names and those names that may be used are set out in Naming and registering websites and social media channels.
Public sector bodies may register .gov.uk domain names for a variety of purposes:
Email only purposes
Websites, including those for campaigns, education, information and transactions
Page redirection (e.g. for alternative spellings of domain names)
To maintain access to information on the UK Government Website Archive
Domain registration is requested via an Internet Service Provider (ISP) to the technical administrators of the .gov.uk second level domain, JANET(UK). JANET(UK) acts as the domain name registry, holding information on which domain names are registered and who owns them on behalf of Cabinet Office.
Cabinet Office is responsible for approving requests for new domain names and any appeals. The .gov.uk domain name approvals and appeals process is described online.
