My understanding is that different CCGs give their Type 1 courses different names. DAFNE is the most common. My CCG calls it Freedom 4 Life and Bournemouth CCG calls it Bertie and makes it available online.
If you want to go on a course (which I would recommend as they do change over the years) is to talk to your diabetes team (or DSN) and ask what is available in your area. If they do not offer anything, Bertie online is a popular self paced option. Unfortunately, you miss out on the discussion with others with Type 1 which I found the most useful (and eye opening) when I attended my Freedom 4 Life course.
