If you want to move an existing domain name to us in order to host your web site, we will not charge any extra if the name is a .uk domain name (unless it's due for renewal of course). Other types of domain names are subject to a transfer fee. For global domains, if you have not renewed your domain name in the last 45 days, the transfer will result in an extra year being added to the renewal date.
