There are privately owned chargers springing up in many public carparks (shopping centers etc) plus there is already an app that lets people use their privately owned driveway charger (7kw or more) be 'hired out' to others to use and they get paid for the usage (and make a small profit on each use as well lol)- just have the app on your phone and you can see any free available chargers located near you to be able to plug in and charge... (some enterprising souls have already had a charger fitted in their driveway, even though they don't even have an EV themselves!!!)

ETA- check out their users map!!! (click on 'charge my EV' and then 'Users map')

Zoomed in on the London area, (note the distance scale bottom right!!!) and the number of available for rent open chargers (green)- AND they have numerous options for prebooking, unattended charging, and 'scheduled repeat charges' ie you can book a 'repeat charge' for up to a year ahead on a scheduled date and time!!!!
