Well, there you go - you have just stated the reason why you SHOULD have the meter that works best for you. Diabetes is a difficult condition to deal with and anything that makes it less of a chore and produce better control should be of primary importance - in effect, they would only save a few pounds a year but potentially need to spend much more should (for example) you need an extra consultation to help with problems, or - heaven forfend! - a hospital admission. Sounds dramatic, but every little step that undermines your ability to manage your diabetes well increases the risks of placing a much greater burden on the CCG's precious penny-pinching budget 😱 I would also apply the same argument to those CCGs who decide to replace needles with cheaper types - if the cheaper ones increase the risk of scar tissue and lipohypertrophy over time then they will make control far more difficult.
