This is a problem I’m having right now on Devonshire Road. Full fibre has been laid in the street but because we live in a flat (a block of 8, we’re all joint freeholders) Openreach are currently unwilling to install it in our building.
The reason other properties in your same street can get it will depend on the building and how the telephony in your building works - the issue is if your phone line comes in through an external distribution point or an internal one.
Because in a block of flats like ours, even though it’s a converted house, all the flats are connected to BT’s infrastructure by a distribution point inside the building. This will likely be the same for most blocks of flats other than maybe small converted terraced houses.
Until OpenReach decide they want to work on these internal distribution points inside blocks of flats then there’s nothing that you can do. I know, I’ve been trying for months.
Adding insult to injury: because FTTP has been laid in Devonshire Road it means they stopped upgrading cabninets in the street for FTTC - and that means my cabinet is still a really old hunk of junk and we can only get plain ADSL My internet max speed is 15Mb down and 0.9Mb up. If one person streams Amazon Prime, most other stuff just stops. It’s frustrating, but without even Virgin in the area to act as competition I’m stuck with it for the foreseeable.
