How can I check if my energy bill is correct?
What you can do to be billed the correct amount
If your bills are usually based on estimated readings, the easiest way to ensure you are paying the correct amount is to send your supplier regular meter readings.
In order to avoid estimated readings, it is recommended that you take a meter reading on the last day of each month and submit it to your energy supplier within 5 days, so they can calculate an accurate bill. This ensures that you only pay for the energy you have used.
If you have a smart meter or AMR device on your meter you should still pay attention to your monthly bills to ensure your energy supplier is using the automated readings provided by these technologies.
