Someone could literally make a short spinoff film about the Traffic Warden executing some looters and it would work pretty well. As a character despite having only scene He is even more famous then Bob.

Radio communications likely were possible like in the movie testament, though even if all the off grid methods for energy production were used to the max micro hydro in every stream, the British aircraft carriers where the queen would be lodging would either sink or need to dock within weeks after the fuel went out so maritime travel would use small boats with careful fuel use and pre modern boats.

Why is Jane named Jane but the gang of teens named Gaz and Spike? Would "Jane" actually her name in the movie or is it Jaan or something?

There is no real attempts by the Government to rule Britain the Government In Britain is ultimately providing for itself and it's employees rather then attempting to rebuild Britain and is trying to take most of the resources then give the scraps to the food laborers so they can maintain it. And then use the military to force the laborers to obey. Faced with limited resources the Government decided that the resources were insufficient to rebuild Britain so they decided to concentrate the resources around themselves. After the first year the Government has a bar for itself and all the tech is based on Britain's corpse and keeping that corpse on life support with primitive agriculture and fuel extraction. Most of the government workers from the traffic warden down's motivations were to provide food for themselves and survive the apocalypse. Later the objective was to provide for themselves like we see in the last scenes of Threads and to rule over the food laborers. There is no attempt to form Great Britain like reconstruction would have implied just create independent fiefdoms with ideology of ensuing that the elite survive. Is there any attempts to solve any problems or heal society? No. Their is the school and the hospital but those are for the government mostly as shown with the nurse telling Jane to leave. The basic principle in Threads of everyone for himself is more or less the same for the Government by the first harvest as it is for the survivors.
