I have done exactly the same. But I never received any confirmation on address change. Called BCIS, it seems my new address has been updated.
Every 30 days I called BCIS to do an enquiry on my case, everytime they said I would receive letter in the mail in 30 days, but I have not received any. Have been doing this for 3 months now.
