I'll worry about it if we start getting power cuts I guess. It's not a super high priority item though.
With my current SMETS1 situation, and the fact that I'm not sure I can get onto Bulb EV tariff (definitely can't without smart meter working - they won't replace it), I'm instead considering switching to Agile. I think with Octopus the electric kwh cap is 55p/kwh on Agile, which isn't much worse than cap pricing.
The export pricing is uncapped though, and it's possible I could arbitrage energy with the right luck.
Besides that though, I think battery and inverter are Agile aware, so could charge on cheaper times, and export rates for Agile export are good for any excess generation, with prices capped for 12 months I think, this sort of makes sense as a hedge?
