If you charge with an Electroverse RFID card you pay your money to the Electroverse charging network. Example: Osprey charger at Elm High Road, PE14 0DQ Electroverse price 87 pence,
MFG Charger at Clipbush Lane, Fakenham NR21 8SW 79 pence.
The price you pay to Electroverse/Octopus is the Osprey/MFG price + the charge taken by Electroverse for listing them in their app and using the Electroverse RFID card.
I have an Electroverse card and an Ionity card. At the same Ionity charger Niedersachsendamm 2, Delmenhorst 27751 Germany, I pay 59 cents with Ionity and 70 cents with Electroverse.
Who do you think gets the extra 11 cents?
So of course it's biased, as it wont take you to chargers where it doesn't get a kickback from the charging operators.
