Thanks. No poles here, everything is underground.
I can see one of their covers from my window, I'll see where logically it may run. Even more frustratingly, due to the age of the wires in many of the houses around here, the pavement has already had trenches dug to presumably run new lines to multiple houses, not even that long ago (within last 10 years). I know mine wasn't one of them though, although my line had lots of issues when moving in as it was an old shared line perhaps, can't remember exactly. The previous occupier did not have an internet connection.
The issue I have is that openreach don't seem to have any plan to come back. Much of the surrounding estate shows as FTTP available, presumably because only a few roads have got DIG cabling, either due to odd developer choices or possibly previous remediation work since the estate was initially built. So even if I do run a conduit, who knows if it'll ever be connected.
