What are you Prepping for.

Evacuation does not come naturally to the British, granted Children and some mothers were evacuated in WW2 but that was mostly from London and they only stayed away a few months at most.
in my home city of Plymouth nobody evacuated, maybe Devon people are made of sterner stuff, anyone in the Northern part of the city walked out and spent the night sleeping on the moors and walked back in the morning when the all clear sounded (I have that from my first wife's late father who worked in the dockyard).
as for ALL these immigrants, immigrants are a very low percentage of the population of a whole and they settle in areas which already have a community of migrants, London, Birmingham, Manchester, Bolton etc. once settled they arent leaving, and the different ethnic types dont mix, there are more migrants stuck in places like Lesbos, Italy and France than ever get to the UK.
I dont say that anyone near a big city wont have a problem with scavengers post SHTF because they will, but scavengers roaming the land like some type of human locusts is just fantasy and only that.
nobody but nobody will go anywhere until and unless the lights go off, that will be some time down the time line of events and it will be the final straw and far too late for most people to do anything.
