Hi @glendandavid, if any period of time (even just one hour) is not reported directly by your smart meter, your bill will show as "estimated" (even though the estimate would be very close to your actual read in that case) . This can happen due to minor issues with the meter setup, especially if it's just been installed. I'd suggest checking your next few bills. If you no longer see estimates, great. If you're consistently getting estimates, it's time to investigate whether there's an ongoing issue.
