Are You still receiving estimated bill despite installing the smart meter?

Smart meters are designed to provide accurate billing information. However, if you find yourself still receiving estimated bills, there could be two main reasons for this. Let’s explore them along with potential solutions.

It is common for the initial bill following the addition of a smart meter to be estimated. However, you can expect the next month’s bill to be more likely to reflect accurate pricing.

The second reason for receiving multiple estimated bills after smart meter installation is if you are using a first-generation smart meter.
