Idiots guide to EV tariffs please?
Discussion
I’ve just taken the plunge and purchased a 22 plate i3s. I do less than 20 miles a day during the week with a few more on the weekend. From my understanding a granny charger will suit be fine (for now) and that’s what I’m using as I type.
The question is regarding EV tariffs. At present my octopus fixed rate jobbie is coming to an end. I’m in a fair amount of credit. The obvious choice is to go with an octopus EV tariff, but is there better out there?
Thanks in advance!

At 20 miles a day (every day of the year) you'll save about £200/year by switching from Octopus standard variable to Octopus Go.
If you get 3.3m/kwh you'll replenish your 20 miles in about 4 hours - you get 5 hours on Octopus Go.
You pay a little more for the daytime rate, but a lot less for the overnight rate. The whole house will be at the cheap rate overnight, so you can save more by shifting some load to these hours if practical.
There are other EV tariffs knocking around, and you might save a tiny bit extra. But beware 'too good to true' like Tomato Energy who have just "gone bust".

Be aware that if you switch supplier, you may have to go on the 'standard' tariff for a week or so before being allowed to have an EV tariff. I switched from Octopus to EON in May to get 6.7p for 7 hrs a night, and although I was aware of this, my other, petrol car broke down so I had to charge at 28p / kWh for a number of hours. 
The tariffs change regularly but uswitch should have the available ones. I'm on Next Drive V7. They're already up to version 11, at 7.5p overnight and 1 hour less, so I'm please I fixed mine. You do pay more in the day, slightly above the cap because it's a specialist tariff, but the gains outweigh this, for me.

I'm with octopus and drive a Nissan leaf, I have the intelligent go tariff. I now only use the dishwasher, washing machine and dryer over night and my monthly average cost per kwh is generally down in the low teens.
So I would recommend staying with octopus
Exactly the same here - well, nearly. My dishwasher doesn't have a timer delay. And I'm on Octopus Agile. My average cost last year was 15p per kwh, so I'm happy with Octopus too.So I would recommend staying with octopus

Same here, we only use the same appliances overnight, as well as charging the PHEV (Passat GTE) and the EV (Model 3). We also charge our solar battery overnight, which tends to put our grid usage between 90% and 99.9% on the cheap overnight rate. I’ve managed as low as 7.07p/kwh average for a month, last month (billed on the 25th) was 7.67p/kwh average.So I would recommend staying with octopus
