Edit: I'm also on a variable contract
https://agileprices.co.uk/ shows the price for a given region. For example back on October 1st you'd actually be paid to charge your battery --
Because of the government's meddling in the market it's no longer available for new customers, so if you have the resources or ability to smooth your load, it's meaningless, you can simply claim your massive subsidy from the government and recharge your 80kWh car battery at peak time for 35p // £28, with the taxpayer picking up the extra £52.
But in a free market you'd charge at low demand times (say overnight when you could have been paying 10p/unit) and either use it, or possibly sell it back, at high peak times (that 80p/unit)
(I'm not sure how feed in tarrifs worked with Octopus, but a system which would reduce the load on the grid has been scuppered by the government with the inexplicable energy policy)
