Until I get these updated (hopefully during the Christmas break), I think these tables/diagrams from the old thread remain useful and worth linking back to (well I would, wouldn’t I?) I’ll add any updated versions to this current thread:
My only comment on the second link would be that in the new Drone Code, the CAA take the view that in A2 and A3 your 50m* separation distance to people:
includes people in buildings and transport, including cars, lorries, trains, boats.
The regulations are not really that clear, especially in A3, where they refer to uninvolved persons who are endangered by the drone - it’s probably difficult to conclude that somebody inside a building is endangered by a drone flying outdoors.
*for legacy drones (30m in A2 when C2 drones become available)
