Honestly, I was primarily concerned about UKBA receiving the darn thing, as searching over on the immigrationboards forum about NCS Hammersmith shows various timescales of UKBA receiving documents from them (although the staff at NCS H&F were very lovely, and even pointing out to me where the ceremony will be held). But I called this morning for the tracking number and hooray, it was signed for on Friday!
Now we'll see what affect the Christmas period has on things, compared to the recent zippiness with which they've been turning around applications
