Once EV's reach critical mass home charging will be taxed.
Not possible as there's no way for any smart meter to distinguish what work the electricity flowing through the home circuitry is being used for. If they tried doing it through wall chargers people would simply switch to using granny chargers plugged into a normal domestic socket.
Most analysts seem to believe that the strategy is to move towards road pricing to replace loss of fuel duty, but they still haven't decided on the best way to do it. My guess is that it will be a combination of extending congestion charging to all built-up areas, implementing route pricing on the heaviest routes, and bunging a mileage charge to be levied at MOT time.
