Re: Nowhere else in the UK would this happen
I think what the uninformed are talking about, is what happens when the weather "nukes" the infrastructure across a wide area, and there aren't sufficient generators and human resources to fix it all within hours. So there's triage. The most economically important bits get fixed first. Which does mean that London will be prioritized over (say) Swindon, which in turn will be prioritised over Lower Cheeseworth (I made that one up).
