ive got a charger at home but its currently running at half power as ive a cable to still get replaced, so it supplies 3.6kwh. That is roughly equ to a granny lead or slightly better, and it does take a while to charge but it is just now and then(maybe 1 time a week on occasion, 2 for charging) My electric is just standard; ie, no ev rate. I pay about 28p a unit. I could get it cheaper tho but i dont currently do enough miles to make it worthwhile. I used to have a chr hybrid and i and paying less now for fuel by a fair bit still, I would be a lot better if i had an ev rate tho and at your mileage that would be worthwhile.
