Most SMETS1 meters are supplier specific, so if you move suppliers, the meters go into dumb mode, which means you will need to take readings yourself, which on some of them is not an easy task. So if your like me, wait for SMETS2 meters which should start to arrive early next year. If your planning on staying with your current supplier then it doesn't matter. I also bet, those that have SMETS1 meters with a current supplier, will be bottom of the list for the new meters.
