I had a similar thought as I couldn't specifically remember flying past it (but I guess I must have)!
St Georges Wharf - according to a picture on wikipedia - was showing a similar level of completeness (e.g. above the surrounding) in Feb 2012 (even the crane), you'd therefore reasonably expect it to be shown on a 09/2012 London Heliroutes map and probably on the Battersea plates if the appropriate procedures have all been followed.
I'm sure AAIB will look into all that though
