Pretty sure the Tesla onboard computer knows where all the superchargers are. Their PR says "up to 170 miles of range in 30 minutes", probably enough to either get where you're going or get to the next charging station.
Tesla says Model X can do up to 351 miles range. If it's mostly London commuting, you'll probably only need to charge it once a week, do your shopping at Westfield while it maxes out.
Problem is charging.
Our block has a couple of lifts - lifts are (generally) three-phase, so there' 90% chance that we have a three phase supply. But - I'd have to square with the management company the project required to take a feed from the incoming three phase, put a meter etc in that was registered to me, then run a decent cable out to the parking space (which belongs to a neighbour, who has no car, who allows me to use it. largely I suspect to stop someone he doesn't know parking there, and that I'd have to buy from him in the potential Tesla situation) where I'd then need to install a charging pillar.
I'd say probably ten grand for that lot. By contrast, there's a petrol station on the way to the Horniman.
