Not sure you understand the way the regulator mandates the way this industry operates, Openreach is a wholesaler , it doesn’t have a retail division, it’s entire ‘business’ is building network and offering equal access to it to any retailer that wants to use it , who then offer services to consumers , BT is one of many companies that use OR ( in fact BT is the only company that if it wanted to build a competing network to OR,would not be allowed to do so ) every other service provider could do that and many do, in that they use OR in some places and have their own network in other places .
So , if OR FTTP doesn’t exist where you are , in what way can they then ‘offer’ FTTP services to ‘partner’ company’s in your area ?, it’s a bit nonsensical.
If your area is served by OR ( at some point in the future ) then you get to chose one of the many providers that use OR, if an alternative network provider serves your area , you can use them ( almost certainly tied to that company with little or no choice ) …that’s it
