Re: I've been pointing this out for years.
Thinking about this in the context of the Government wanting everyone to be buying electric cars soon ...

I guess it depends on where you are, but they're pretty uncommon where I live (as are electric cars), and I've seen vanishingly few added to properties after the government slashed the subsidies on them.
A significant number of properties will find it hard to charge electric vehicles - either they're Victorian-era terraced houses with no off-road parking (no running a power lead across the pavement...), or they're new-builds with a "parking forecourt" even further away from the actual property.

When I changed suppliers, I didn't notice any offering on-demand pricing..?
