I tend to check out the cheapest suppliers annually and change if its prudent.
Slightly concerned that if the meters aren't compatible across suppliers the freedom to switch will be compromised and competition will suffer.
That won't be the case.
It's only a slight issue with some of the meters from the early trials. People on those meters can still switch but it initially meant leaving the smart trial and the meter being switched to operate in dumb mode. Increasingly, these are becoming more interoperable as most suppliers are gearing up and some processes have been derived to allow switching while continuing to be "smart".
The full rollout won't have any such problems as the meters, processes and central systems are all being designed with this in mind.
