Just seems like throwing away money for some limited convenience.
I did 288kw of charging in Sept. I’m not on a smart tariff as I don’t have a smart charger. So I use Octopus Go at 8.5p per kw, 5hrs a night. My Sept. charge cost for 288kw was £24.48.
I’ve done 7000 miles in my car in the 9 months of 2025, I’ve fast charged it twice at Tesla Gretna Green, 115kw in total, cost £66.82. My average consumption is 3.2m/kw, if I remove the mileage covered by the Tesla charges, then I’ve spent £175 to charge my car, or, if included, £242. Your DD would have cost £535 over the same period. Over double the cost.
Ok, you get a bit more public charging, about 50kw or so, call it a single charge at Tesla, but it simply doesn’t add up. Intelligent Go or EON would save you even more and allow peak charging if that was definitely required – and it wouldn’t be KW limited like the Ovo offering.
So, over say 3 years, you’d save £900-1000 – something to put towards the next AP.
In life, it's not who you know that's important, it's how your wife found out.
