Hi Aqua!
I was officially diagnosed at the beginning of December (though I use my first blood test in November as the real date), and my foot & eye appointment is taking place at the end of February, so 10-12 weeks (ish).
I'm in Stockton-on-Tees (North Tees & Hartlepool NHS Trust), but can imagine it might be slower in some trusts. My nurse doesn't do feet tests, I asked, everything is done at a clinic.
Hope you get a good version of the Desmond course. Although they are all meant to cover the same subject matter (reading from a book) sometimes it's the interaction and presentation that makes a difference. Mine was split over two half days. The first session not so good, the second brilliant, though I knew most of what they covered anyway from pre-reading on here and other Diabetes support groups.
