@Peter I was on Octopus GO (without an EV), but changed to Octopus Fan Club. Unfortunately, you can’t have 2 different Smart tariffs at the same time. The last fortnight my electricity has been half price for about 80% of the time, 20% discount about 15% of time and only 5% of time standard rate.
I can see when there’s more and more demand during the night (when millions are charging their EVs) these EV tariffs will be less generous, or the daytime rates will be higher than none EV tariffs, like Economy7 tariffs.
Especially if purchasing an EV, you need to do MANY short journeys to recuperate the extra up front cost of an EV. There’s less efficient when travelling 70mph.
Another thing that would worry me as a private EV buyer is this presumption that EVs are much more reliable. I don’t know if data backs that up. On the surface people might thinks there’s a tiny amount of moving parts compared to ICE, but most ICE cars that breakdown, breakdown due to electronics.
I’m not anti-EV and often play BOTB in the hope of winning a new car. I always try to win EVs such as the BMW i4 M50. As I know it would save my money on fuel over the equivalent BMW 4 series. But the equivalent 4 series is so many thousands less than the i4 EV that if buying, I’d go for the 4 series (actually I’d buy the 3 series touring estate).
Previous car got a conservative 9miles/litre mixed driving. The last few years I’ve only been driving around 5,000 miles/year. Current price of fuel £132.9/l at Sainsbury’s Denton (just under 5 miles away). So 14.76p/mile. That’s £738/year in fuel. Using your figures, you’re spending just over 2.5p/mile of electricity. So £125/5,000 miles. That’s £513/year less than my old car. On a 3 year lease you’re saving £1,539 in fuel costs. I’m not sure how much the AP differs between an ICE and equivalent EV on Motability, but I’d guess the £1,539 saving in fuel would just about cover the difference.
