To note, sometimes this didn't happen immediately. My grandmother lived in an early 70s build and they had no phones for the first three years she lived in there. Not sure if they were not wired or it was a trunking / exchange issue that caused it.
Incidentally my sister in law has just moved to a new build estate in early Jan and they don't have a phone service yet either because OpenReach didn't build a cabinet at the end of their road.
Less of an issue today but nice to see progress!
