My Octopus go day rate has just risen from 41 to 44p. This now means just to break even you have to use over 40% of total at night. That also means that even if you charge your EV during the cheap overnight period your REAL driving cost is NOT 12p per unit as the average unit price per day work s out at nearer 30p per unit. My previous Octopus bill actually showed night usage cost and day cost and gave an average of 29p per unit. This, even with exclusive charging using the night time EV tariff gives the real cost of EV use and for me works out at 9p per mile (average 3.2 miles per kWh my MG ZS EV). For comparison my petrol car costs around 14p per mile same type of driving. The EV is still cheaper per mile in fuel but nowhere near enough to offset the extra cost. Based on my car, my tariff, my EV and my driving.
