Most meters are designed to operate in above 0C temperatures, normally +10C to 40C. It is usually the test strips that are sensitive to cold, but the meters use commercial grade components, so generally are also limited probably 5 to 50C. Never seen one rated for sub zero.
Each CCG will have their own list of recommended meters that they will support, but these are generally derived from the same study report that listed some 20 possible candidates that meet the new NHS cost criterion of < £10 per 50 strips and being compliant to the latest ISO standard (2013). This list of candidates barred most of the well known meters and all the older meters, so it looks like a strange set of bedfellows that I had never heard of.
Of the 6 meters that I was recommended, one was not available and the supplier was dodgy according to Companies House, and 2 had technical issues. I finally chose a meter that was not on the list of 6, but which otherwise met the criteria, and I went back to my CCG and got it approved for my use. It is brand new and it also does ketones, which I felt was necessary but not essential for my care. None of the formal selection meters did ketones. I am now using the new Caresense Dual from Spirit Healthcare, and I am pleased with it.
You may find your local CCG has one of the well known meters on its list since they need to support T1D as well. It varies and is a real postcode lottery, so ask your practice what they have elected to support in future.
