Yes. In order to buy web hosting and not a domain name, you will need to have a domain name already that you want to simply keep with another supplier. You will also need to have control of this domain name so that you can change the name-servers on it to point at our servers. In this way your domain name will be referring to our servers. You will also be given this option when trying to buy a hosting package through us. In order to do this, you will need to add the domain name to your purchase as a transfer request, add your hosting choice and then remove your domain name from your basket before you reach the payment stage.
