The gas supplier installs AMR (Automatic Meter Reading) devices for their Mains gas business customers. This means that your meter readings will be automatically sent to AvantiGas. The texts will also be sent to your online energy account. This way, you will be able to quickly view your updated energy usage.

For customers who do not have the AMR, meter readings are submitted manually in the following ways:

  • Online
  • Via email

If you are providing your meter reads manually, be sure to:
