Again, I can only go off what I've been told (anecdotal) and what I've read, but the most appropriate answer would be - how long is a piece of string?
The public chargers are much quicker as they have a higher kWh rating, so he said he can normally charge his van in between 15–30 minutes.
This is where the additional cost comes. The Tesla network, which you have to buy into, are super quick at charging, but the access is very limited.
The cheapest option is as at home, yet as
@jazzy said you need to fork out for the cost of the charger, so that's an additional expense. They're relatively slow, too.
The ones in the lampposts around here are less than 5kw per hour, so you're likely going to be around the 8-10 hour mark to get to the magic 80% mark.
He simply doesn't have the time to leave his van for that long away from his house, although it's 53p per kWh rather than the 85p*. But the 80% bit confused me.
He said you should be keeping the battery between the 20-80% mark, and charging above the 80% a) takes disproportionately longer, and b) reduces the batter life.
I said doesn't that mean you get less miles on a charge and he said yeah, so the 200mile range I mentioned probably isn't even accurate - it's less.
I'll fill my diesel at Costco for around £80, it takes me five minutes at most, and it lasts me a fortnight based on driving habits. EV do not sell themselves to me.

His home rate would be 7p per kWh, but he can't due to where he lives.
