Hello Brian and thanks.
Yes I know, it did sound a bit over the top didn't it?
I was mainly thinking about if it continues into tomorrow and longer, really, NOT just over one night - that's when it will be worse (food in freezer etc)
Also, no lifts working on the estate - I don't need to use the lift, as am on 1st floor, but am worried about the elderly etc and also, no lighting, I presume, will be working, within stair wells etc. so not good for all who live there.
Anyway, yes, over the top maybe, the way I posted it - made it come out sounding wrong - but, one night won't matter at all, in the context of things; not for myself and my sons, for sure, but it could be/will be, very bad for some other residents.
Let's hope it won't come to that anyway, hey? 
BTW -
I meant to put this link in my post, before, but forgot.
Thought this may be helpful, to keep track of events, if it updates often
