If you simply want to point your domain at another hosting company, all you need to do is update the name servers for your domain to your new hosting company. We will continue to bill you for your domain registration fee when it becomes due for renewal, your new hosting company will bill you seperately for their services.
If you want to completely move the domain to a new registrar/provider, the exact procedure will depend on what type of domain is being registered. For .ie domains, you just need to contact your new hosting provider and they can usually arrange everything. For .co.uk domains, the procedure is similar but Nominet require us to explicitly release the domain — we will do this promptly upon receipt of a letter of authorisation from the domain owner. For .com, .net, .org, .biz and .info domains, you will need to select a new registrar and follow their particular procedure for domain transfer — we will need a letter of authorization to unlock the domain and release the transfer code. Please note that it is not possible for us to refund the unused portion of a domain registration.
Due to the way domain changes propagate around the internet, it may take several days for all intermediate nameservers to update. During this time, people accessing your site may see either the new or the old site, so we recommend that if possible, you temporarily run both sites in parallel during the transition.
