My son's chocolate and coffee shop has a 50kW EV charger at it.
AFAIK he owns it - he controls the price, gets the revenue and pays for the leccy - but I think it has conditions on whose network it is connected to given the (possibly 100%) subsidised installation...before he owned it.
I'll have to look at the contracts at some point to see if he could go with a different provider or even just take the payments by card directly.
The current operator had it on free vend for a while even though he asked them to put it at 30p/kWh so he ended up losing £1500 on it last year. Still trying to recoup the money due to their error.
Fairly sure they are also putting it on free vend when people ring up to say there's an issue with their cards so he may well still be losing money on it.
