That�s kinda what I was trying to ask, what makes �BT� not have to provide copper based voice service to addresses such as these ?
I had thought that unless huge costs were involved the USO obliged them to provide service.
The USO does indeed oblige BT to provide a service to everyone, with some pricing provisos.
However, Ofcom allows developers to choose who they get service from for telecoms, and they are keen to ensure that BT/Openreach is not the only choice.
There's obviously a gap if a developer chooses not to involve BT during the planning & early build stages, as there is no infrastructure built into the streets.
A new owner can ask BT to provide a service when they move in ... and BT are obliged to provide one if they can. That involves code access to publicly-owned land, and wayleave-controlled access to private land.
But...
While the build is going on, the streets are actually private land. And the developer does not have to reach a wayleave agreement for BT to dig up the streets and pavements ... so stopping BT in their tracks, and effectively handing IFNL (or whoever) a temporary monopoly.
The homeowner might be able to break that monopoly if there is a wireless operator in range. Otherwise there isn't much they can do ... at least not until the road is adopted.
Adoption is an issue. Councils want new-build streets to be in pristine condition before they are willing to adopt them, which often means pristine tarmac with no rough roadworks. The developer isn't likely to want to allow BT to start digging the streets or pavements, for fear of it causing a delay to adoption.
The council might then ban roadworks for some period after adoption, because the surface is in good condition.
Once Openreach have reached a point where they can get access to the street, that pricing proviso kicks in. The USO obliges BT to provide a service if it costs them less than around £3,500. Any more, and the owner can be charged.
You can imagine that, now BT have to dig up the streets to provide service to a single house, that charge ceiling is going to be breached easily. It really is only cost-effective to put the utilities down early in the build, for everyone. IFNL, presumably, are counting on this to keep a monopoly beyond adoption.
