I don’t know which electric tariff you’re on, but worth pointing out that if you’re with Octopus on their Intelligent Go tariff, you get 8% off of many chargers (including Ionity and Gridserve) – as in, at literally every supported bay. The only big one missing is Tesla. No subscription needed either, you just have to charge through their app (Octopus Electroverse). You can, and i only recently learned that, charge and pay through your electricity bill, which i find awesome. Just throwing that out there.
Yes get the Electroverse app and order their card too but a Tesla or Ionity subscription (I’ve got both) usually works out cheaper
