In reply to girlymonkey:
I think it's pretty difficult to do a comparison table as the offers have so many variables to consider, such as whether all electricity use applies at one price or your smart devices get charged differently from the rest of the house.
This seems like a reasonable rundown of the current options to consider:

We currently have solar plus battery and are on Octopus Flux. We are planning a heat pump, and Flux still looks like a decent option with that added but it would be great if we could get on Intelligent Octopus Flux to maximise the battery potential and maximise the efficiency of the heatpump. I have requested an integration for our (Fox Solar) battery through the app, but I have no idea when they plan to start including other makes than the products that they sell.
EV will probably be a fair way down the line for us, hopefully by then everything is better integrated.
