Perhaps in time those 7kW chargers at Sutton Sainsbury’s will get used more, & Reigate has a couple of fast chargers (Wray Lane is very close to the A217 & M25 so could be useful as there’s a cafe & viewpoint).
Waitrose/John Lewis has 7kW chargers in Horsham, sheltered in the underground part of the car park, they charge for parking unless you happen to have a Blue Badge so very handy.
Seems there are 3 problems at the moment:
1. Not enough chargers of the right type in the right places.
2. Where there are few chargers they are often out of order.
3. Gaps in the charger network where some towns have just ignored EVs & seem to want the town centres to die rather than invest in a few chargers.
