which supplier are you with?

Octopus energy, on the agile octopus tariff: https://octopus.energy/agile/

For the brave!

But seriously (author of article here) I think that agile tariffs and more demand flexibility are probably a big part of the solution

I have the luxury of a 13khw battery, so it might make sense. But I suspect that when I need to use the grid will be uber peak £1.04 per kwhr.

Edit: for those who are curious, here is some data on prices over the last month: https://agileprices.co.uk/

I guess you can’t have two suppliers, one on a traditional fixed contract and one on the octopus stuff, and choose the best one

You can, but you need to own two neighbouring houses and be willing to install an (illegal) cable between them.

Octopus Agile cap the prices at £1/kwh.
