I think the volunteers thing will take a little while to get up and running.
I would imagine, though I don't know, that there would have to be some sort of checks to ensure volunteers are "suitable people" and not undercover axe murderers, rapists and money launderers!
They also talk about matching local volunteers to local "extremely vulnerable people", so that will take a bit of time to set up.
The other thing is that they are trying to build all this on shifting sand.
I'm the shielder in this house and DH is stringently following the social distancing guidelines.
We will be ok, as long as he stays well.
If he goes down, we're both f**ked!
And, of course, volunteers aren't exempt from contracting this virus so, no doubt, there will be much reshuffling and reorganising going on almost hourly.
But, on the bright side ,we have electricity, running water and Mumsnet .😉
