I am planning my first over 250 mile journey in my MG5 and am looking for reliable charging locations en route. Pre EV I would have gone M40, M25,A127, but realise we may have to vary the route to fit with reliable charging locations. I would prefer to use Instavolt or possibly Osprey chargers. There seem to be several BP Pulse chargers near Chelmsford. Have any MG5 owner had problems paying by credit card at these? I have downloaded zapmap. Where would be a good place to stop bearing in mind I have nowhere to granny charge where I am staying on the coast?
