Based on your figure :
Octopus Standard rate 4390kWh @ 28p = £1229.20
Octopus Tracker (it has been below 20p @ kWh over the last few months) average 20p kWh = £878
Octopus Go rate 29.9 2723kWh = £816.90
Charge car 5000 miles @ 3 mile kWh 1667kWh @ 9p = £150
Total £ £966.90
Personally I would go for a Octopus Tacker, unfortunately there is a waiting list for Tracker, in the short term I would go for Octopus Go.
I am fortunate enough to be on Octopus Agile averaging around 12p kWh
Unfortunately I have suffered a brain injury and occasionally I get confused and often say the wrong thing.
