I had a follow-up call with the doc this morning who seemed quite impressed with how things are going and he's agreed with me going down to 1 x 500mg Metformin now, with a view to coming off it if my next hb1ac is also under 48. If I'm then still under 48 at my annual review in March next year then they'd regard me as being in remission. Basically suggested continuing doing what I'm doing with the low-carb and keeping my weight down, as it's clearly working well.
