Paul the way I see it at 26p per KW from Lidl
421 miles at my worse would cost £44 I know there is the odd places you can charge for free but let’s assume they will disappear. However Motability and others are focusing on address like yours for other options such as lamppost points and shared options. So it could be worth having a chat with Motability to ask if anything is in the pipeline for change. As for the cable across the road mine was put underground approx 30 metres you have to explain to people that YOU are doing what is being asked of you for the future, they are making it difficult.
