G.Fast can do up to 330mbps via Openreach, with 660mbps coming soon.
G.Fast though is only being delivered to such a small minority of connected users, I'd be amazed if it was above 1% of connections. It's a fudge of BT trying to prolong the life of rubbish old copper rather than spending the money on replacing for a true fibre supply to the end user.
