We're still running on petrol. Although we had the EV Charger fitted last Saturday, Octopus haven't yet managed to swap our tariff over to one that makes it financially viable to charge.
Beforehand I'd found Octopus really effective, but in the last three days they've charged me double for March's electric (soon rectified after they finally accepted that my calculations were correct, and theirs were wrong) and can't give me any definite time for the Tariff switch - so far I have been told 'usually 48hrs' (after 72hrs), 'it should be soon' and more honestly 'I haven't a clue'.
