Not sure if I'm getting confused here, but it seems that you can't get on Octopus Outgoing whilst also being on Go still, this includes the fixed Outgoing and the Agile Outgoing.
Instead you can go onto a less well paying SEG tariff, so possibly not one we can get onto for 15p/kwh export whilst staying on Go then.
Edit - Calling it, we can't get onto this 15p/kwh tariff with Go for import:

The only export one we can use is the SEG one. I hope the SEG one goes up a bit more though. 4.1p/kwh is daylight robbery.
Do I need to be on a special tariff for my energy consumption?
No, Outgoing Octopus is independent of your regular consumption tariff.
Currently, you can't be on both Outgoing Octopus AND
Octopus Go, our electricity consumption tariff designed for electric vehicle drivers. We've made this decision because both are such incredibly good value tariffs that it would be unsustainable for us as a business – the equivalent of letting people buying goods in a shop using a "3 for 2" offer and then bringing them back for a full price refund! The combination of Outgoing and Agile works really well and offers potential for great savings. You can choose to be on Octopus Go and join our new SEG tariff for Outgoing, offering 4.1p / kWh for your export – just get in touch with our team to take this option.
