If there isn't a link to it, it generally means it's no longer commercially available. I.e not availabe to sale to the general public. It would still be available for their home moves and retention teams - so that current customers can port the product to a new property and for EDf to attempt to retain customers by offering a better product (even at a reduced profit margin or short-term loss).
Armed with this infomation you "might" be able to call their customer services team's and negotate transfer to this product - there's no guarentee's of course but you might get lucky.
