If you had your pump in 2007 you should see your DSN, as it should will be due for replacement at the end of the 4 year warrenty period... This is common practice as the companies do not support repair etc after this point!
You can under the NICE guidelines choose which pump you want, the pct can't say you can only have this or one of these, if a pump is licenced for sale in the UK, you can choose it might have to battle with the diabetic team over this though but it's your right under the NICE guidelines..
Not sure what pump you have at present or the reason why you've choosen the Veo, but if part of your choice is based on it's intergrated CGM ability, this part of the set up isn't provided as part of the package provided/funded by the PCT... You either have to purchase the necessary reciever/transmitter (separate unit) and fund the sensor yourself..
CGM's are not covered by NICE guidelines, so if you feel that you would benefit/require one but need funding then you would have to apply to the Special Case Committe (I think that what it's called) at your PCT to see if you have a strong enough case to warrant funding...
