I have been a silent reader of this forum during the long wait so wanted to post our timeline as we found it so helpful to follow everyone else's journey!
Original visa: Tier 1 (General)
Main applicant + 4 dependants
Application Set (O)delivered by courier : 20/01/2014
Payment taken: 22/01/2014
Biometrics enrolled: 19/02/2014
Approval letter and documents received: 21/05/2014 (dated 19/05/2014)

Such a relief that the wait is finally over!
Good luck to those still waiting, we know how tough it is.
