Yeah, Octopus Go Faster should suit you well. I'm with @Paul M here, we run our appliances during our GoFaster period. GoFaster is a little more usable that Go as you can choose a more convenient 4 hours, not just 00:30 to 04:30. We have ours set to 21:30 to 01:30 (any 4 hour period from 20:30 is available). As we have an MG and a Chargemaster dumb charger I can set the car going before bedtime.I am not sure if Octopus is the best option?
