Billing
1st Energy bill every month so you can manage your costs more consistently.
- For customers with a smart meter, bills are based on actual meter reads where possible.
- For those on quarterly-read meters, monthly estimates are used, typically dividing the previous bill into three. You can also submit your own readings through the portal.

This monthly approach means you only pay for what you use.
