My current supplier is 13.31 p p kwh and 21.4 p per day standing charge
Octopus go is 15.9 p p kwh peak and 5 p for 4 hours off peak with a 25p per day standing charge
Is the 4hrs worth switching for?
@ 10k miles a year I'd need to be putting 27 miles a day charge into it, on my current tariff @ £3 per hundred miles (the app says that's what I'm averaging) that would cost me 81p a day to put those 27 miles charge in and would be 30 pence a day with Octopus
So that's 51 pence a day saving on charging the EV if I switch to Octopus that's IF I only charged at home which I don't, I think at least 50% will be charges at work and whilst shopping etc so say 25 pence a day saving, less than £8 a month but then there's the other 20 hours of the day when it's more expensive than my current tariff and with a higher standing charge.
Spending about £600 a year on leccy (without EV) the Octopus tariff is about 20% higher on peak so that's and extra £120 a year, balance against the savings of £8 a month (£96 a year) then it would actually work out more expensive for me to switch, very rough workings out obviously
I think I've spent half an hour of my life working out that it's not worth switching for me, maybe it was time well spent
