I applied for my wife's SET(LR) using new service and super priority next day option on 01 Jan, 2019 and booked appointment for £100 in Birmingham centre for Wed, 09 Jan. Location near Birmingham airport was easy to find with ample free parking. Appointment time was for 10am and we got there at 9:40am. Surprised that room was full of people, probably from morning appointments. The waiting room was pretty small and cramped. Main officer in charge and all others were nice though, friendly, first checked appointment details and passport, then called for biometrics after 1/2 hour and finally we were called for document upload after another 1 hour. In all, we left the office just after 12pm, so process took around 2.5 hours, because some people take a long time to upload their documents. We however had uploaded most of ours beforehand but still needed half hour for checks and submission. I asked person about document upload page which only allows for uploading to optional documents and she said that was fine. Apparently, the passport scan they do themselves and is part of the mandatory category. Next two days on Thurs and Friday we were expecting to hear from case worker by email within 24 hours, but we got letter in post signed for on Monday, third working day after we had the appointment, which was dated 11 Jan. So it took longer than 24 hours and perhaps because ours was a complicated case. Result was not good, we got refused. But point is, procedure was pretty straightforward. Hope others have a good experience!
