Not exactly sure as I'm not on Insulin, however, my GP recently sent out some GlucoRX meters as the lancets and strips are more cost effective. The note with the meter advised that it had an average BG per day that was useful for DVLA purposes.
Didn't keep the letter unfortunately, the meter's pretty good, a little large and annoyigly the case it comes with doesn't have a waste pocket to put used lancets and strips in.
There was also some talk of one that counts carbs by what meals you have and it adjusts the doses for you she also mentioned they may offer me a insulin pump which ain't never gonna happen as I'm a bricklayer and it would get knocked about etc etc
