There would also be a membership cost of £8.99 per month and as Mark points out, the cheapest rates are between 12am & 4am, which takes us back a few pages where I mentined inconvenience. Even if an EV worked out the same or slightly cheaper than hybrid to run by charging on public chargers, its not worth the incovenience to do so, especially at 12am and why looking home charging is important should you go the EV route.
