I have never used or actually seen a public charging point for some reason they are as rare as hens teeth in our area, I was under the impression these charging point charge around £0.35 kWh our PHEV is now were kWh energy efficient as a pure hybrid at £0.35 kWh it is cheaper for us to press the charge button and burn a little petrol whilst driving, plus I don’t have a charging lead.
Unfortunately I have suffered a brain injury and occasionally I get confused and often say the wrong thing.
