BT Consumer doesn’t ( and would never be allowed to ) do sweetheart deals with OR, and OR have to allow open access to any company that wants to use their products , it’s a bit of an urban myth that there was ever any requirement to use ‘BT’ in the first instance, this myth probably came from developers using inaccurate language to their purchasers , you can see how saying ‘the property comes with fibre from BT’ instead of ,more accurately, ‘the property comes with fibre from Openreach’.
Even on community funded projects and BDUK , the ‘deal’ is with Openreach , not BT, so the undertakings OR gave to Ofcom apply, in fact if there ever was an exclusive deal between BTand OR the industry **** storm that would follow would be hard to miss.
Other network providers do exclusive deals , ( Persimmon Homes for one ) where the only access is to their in house FTTP system , and purchasers have no ‘landline’ choice at all, the only competition from mobile, same as Vodafone , TT ( in York) and others, they are under no obligation to offer wholesale access , and where they do, the ISP’s available are usually linked to the network provider.
If any links to something irrefutable can be provided of any exclusivity with BT Consumer , I’d love to see it, but apart from anecdotal posts from people who were told stomething from ISP’s with a vested interest, I doubt any exist
