I am particularly looking for a study with an emphasis on identity. I am coming up short on actual London neighborhoods. Most of the studies I have found seem to be from other areas in Britain.

London Indian Community (http://www.sasural.com/london/)
North West London OnLine | Brent Indian Community Centre (http://www.nwlonline.net/locations/willesden_kensal_green/brent_indian_community_centre/)
