So pleased that you have made excellent use of a calculator or pencil to see what you are going to save, but I thought I would mention something often forgotten, when you are on an EV tariff it’s a great time to put your washing drying even par roasting a dinner onto timers thus making even further use of the cheap rate and bringing your driving costs down a little more. We have just changed car and reduced costs back to 1.7p per mile without counting the extra household gadget savings.
Good luck with your EV enjoy it
