If you need to update the address details associated with your domain name registration you should do this through your registrar. It is your responsibility to keep your details up-to-date and your registrar's responsibility to maintain your details at your request via our automated system.
However in certain circumstances your registrar may be unable or unwilling to make the changes you request. In these circumstances we may be able to assist.
All domain names have a Nominet account and you can amend your details using our Online Services.
