Welcome to the forum. My understanding is that different medical practice groups around the UK use different meters and they sometimes change them, depending on cost. In NZ there is a national agency that dictates one type of meter for everyone, and it changed a couple of years ago. Everyone just returned their meter and got a new one with new strips for it. Hopefully that will be what happens for you, and the new meter will be just as good, and you won't need to pay any extra money. But, depending on your needs, the meter might not be suitable. There are dozens of types, and there's a list of them somewhere on this website too.
