I think your knowledge may be a little out of date. I charge my (non-Tesla) EV at Tesla Superchargers and pay 30p/kWh at the excellent Ionity (350kW!) chargers.
There are 12 Ionity chargers in Greater Manchester, plus 18 Tesla ones. I've used both sets.
You seem to be confusing home/destination chargers and rapid chargers - which is a common mistake for non-EV drivers to make. Unlike petrol, electricity comes to you.
Doesn't really matter, but that's one location that contains multiple chargers.
Of course, very few people that live in Greater Manchester would use a really fast charger like those there whilst in Greater Manchester. Maybe if you're a taxi driver, or caught short somehow? This is the confusion I was talking about.
