Unfortunately, it seems to be a postcode lottery: different areas have different budget allocations for pumps so have different criteria.
My advice would be two-fold
1. Be very very clear why a pump would help you and what it would help you with. Do you get lots of hypos? Do you experience a huge liver dump at the start of the day? The main advantage of a pump is the ability to adjust the basal dose at different times of the day and to use a temporary basal. So think about how this would help you.
2. Prove you are able to handle the added complexities of a pump. A pump requires more accurate carb counting than MDI because the basal dose should follow your basal needs more closely so you have no "spare basal" to mop up any under calculations for carb counting.
I have had a pump for 18 months (after 12 years of MDI). It has significantly reduced my hypos during exercise but has requireed much more effort to achieve this. A pump is not a miracle cure.
