Thx Kezo, that answers and reasons some of the replies I received from energy suppliers.
I had asked Octopus and British Gas if they can install 3 phase meters. But replied they do not have these meters for my property. In essence they currently do not have 3 phase domestic meters.
I gathered that currently having a 22Kw charger is not feasible at the moment. But it should happen in the future.
But yeah, got a big grey box with 3x 100amp fuse covers an only one connected to the meter.
I didnt know how they connected it to the mains on the pavement until I saw the connecting the 3 cables on a live wire. They had on a pair of big black gauntlets, and connected them to the mains. Covered it with a large torpedo shaped cover which was oozing out grey fluid which I think they filled the torpedo with. Very interesting
