I tried every avenue I could think of to secure NHS funding for CGMS and surprise surprise hit brick walls at every turn. I had/have my consultant's support, have applied to my PCT, appealed against their decision to reject my request ... no go.
I HAVE self-funded the Medtronics CGMS for several months but boy - it IS expensive. Not only do you have to build in the cost of sensors to your budget - which I have found I can use for around 9 days on average - you have to budget for the transmitter device too as this only has a 6 month warrany period and can stop working pretty soon after that period. Saying that, I suspect that the life of a transmitter is reduced if you don't use it with a sensor all the time - I have tended to use CGMS during periods of working away from home, maybe for two or three weeks and then nothing for another couple of months.
The last box of 10 sensors cost me £375 and I believe that the transmitters are a similar price but EACH!
