I agree with @dayskipper
If you don’t have an Indra or Ohme charge point you’re out of luck. It’s a bit like Octopus with their Intelligent Octopus tariff. My home charger was supplied and fitted free by DS and is a Podpoint unit which is not supported on either tariff. Neither is my current EV, a DS3 Crossback E-Tense nor my soon to arrive ? MG4.
