I’m on Octopus Go. Usual off peak pricing. But they occasionally send an email asking you to use less power for an hour later on in the evening (called a “Power Down” Saving Session). If you do that (use less than you usually do in that time slot) they credit you some small amount. If you normally use zero during that slot, exporting a small amount also satisfies the criteria. Currently (until November) they also reward you with an hour of free electricity on Sundays if you do this successfully twice a week.
Gosh, Octopus is a confusing provider…
so the “you need an EV” thing… I mean we didn’t have an EV or a charger when we signed up and they didn’t check at all! We do now though.
Indeed Go is just two rates.
I looked at Flux but it worked out a bit more expensive when I did the modelling… maybe that’s different now though.
