And there are no rural areas without access to mains electricity? (Such as around half of the Hebridean Islands)"
What planet does The First Dave live on? Our cottage nestles behind the Summer Isles and has had mains electricity since the early 1950s and has had mains water for about half a century. And as for Hebridean isles (inhabited ones, anyway), which islands with 100 inhabitants have no mains electricity?
If broadband were rolled out as efficiently as mains electricity was in the middle of last century, there'd be very few rural areas without broadband.
