It has been 18 months since I sent my application to NS, Canada, they transferred my application to London office in September 2009, and it has been in process since May 2010.
Since then I didn't hear anything and when I sent them an email I got a reply that it is under process (background check).
I asked my employers (present and past) and they said that they didn't receive any calls or inquiries so I am a bit confused what the background check is all about!!
Nevertheless I wanted to start this and see who is in the same boat so here is what you need to do:
If your application is being processed in London since April/May/Jun/July , please let us know your updates!! 
Easy and simple!!
