I have never had problems getting strips, or even changing types when better ones come along. I was told by the community team that if ever I have a problem, to clarify she said, 1) I am entitled to as many as I need, not how many GP thinks. If he ever argues tell him that DAPHNE requires a minimum of 4 tests a day, and show them your DVLA letter outlining the tests needed to drive. 2) there is no list of "banned" meters, if its approved it's approved and if it suits you, rather than the practice administrator that is the one you are entitled to use. If the GP still doesn't budge get in touch with your community team, and get them to intercede, (apparently mine are dead scary towards non cooperative GPs)
My brother in law who lives across other side of the country to me, liked convenience and ease of my Accu-check mobile, and got hold of one but was told by his GP that it wasnt approved and he couldnt have the strips, I told my scary sister the above and she took it upon herself to confront the GP with the facts, and the threat of a formal complaint and a letter to the press, result he admitted she was correct, and it was the administrators telling him to cut costs, result his choice of meter and as many strips as he needed. (mind you she is scary!)
