For some reason Octopus discourage random switching. However if you say you are moving for a car tariff specifically they may accept the transfer, they did for me, but that was before the government cap and the Octopus fixed tariff changes.
I’ve completed the application to switch today and seems to be accepted.

Average annual UK household elec usage: 2900kWh (are you likely to be significantly different from average?).
Household elec cost (assume all consumed in the day, do you use much household elec at night?);
2900 x 35.06 = £1,007 (shell)
2900 x 44.35 = £1,286 (octopus)
So, difference of £281 on household usage, for car usage the cost per kWh difference is 35.06-10=25p/kWh.
Assume 3.8 miles /kWh (reasonable model 3 efficiency).
So break even point on annual mileage would need to be (281/0.25)x3.8=4,270miles.
If your expected annual mileage is around that or more, then switch to octopus.

There are assumptions clearly stated. Let me know which bit isn't correct.
(Edit: I suppose the point is a ready reckoner that if expected annual mileage is significantly greater than around say 4000 then not worth the effort going through half hourly data. If it is around 4000 then I agree maybe worth that effort).
The thing to think about, if you can leave your energy hungry things off until it's cheaper. Then you will see the advantage, I already use the dishwasher after midnight before switching and after I should see a drop after.

Cheers guys, I appreciate there's no exact science to my question and probably not the best time of year to be trying these sorts of comparisons when the leccy usage is so much higher (or maybe it is 
). I'm a newbie to all things EV so very much in the deep end of the pool with no armbands.
I'll definitely be doing more than 4k miles a year

No MY RWD on there but would I be right in saying there wouldn't be much of a difference if any compared to a M3 SR?
