More and more National Trust properties are putting in EV charging stations. These are mainly fast chargers, which means they are the slower 11kWh chargers, which are in fact ideal when visiting a property.
I recently visited Castle Drogo down in Devon, upon my arrival I was able to park and connect my car to the charger. You can use the Chargepoint app if you want, I though used contactless. Unlike many other chargers which use contactless they only take a £15 hold on your card. BP Pulse took a £50 hold on a recent charge in comparison. The cost was 50p kWh which I thought was reasonable for a public charger.
What this meant of course, was when my visit to the property was over, the Funky Cat was at a 100% charge ready for the journey home.
