About My Bill

There’s a Lot of Important Information on Your Bill and We Want to Help You Understand It.

Your London Hydro bill summarizes your energy and water usage and charges that have accrued during the current billing period. 

As the sample bill below shows, the front-top portion, referred to as the remittance stub, is a summary of your personal information and the amount owing. It is returned with your payment if you’re paying by mail. The lower-front portion of the bill provides details on your account status and energy usage and should be retained for your records.

The back-top portion contains definitions of the terms used on the bill while the back-bottom section summarizes your water charges and usage.

Understanding all the important information contained on your bill enables you to better understand your water and energy consumption patterns, what it costs and how you can reduce usage to lower your bill.

Water charges listed on a London Hydro bill

  • there are no rate categories, everyone is billed under this rate structure
  • in the new rate structure, there are no longer classifications for different types of customers and a new capital renewal charge has been introduced
  • all residential, institutional, commercial and industrial customers will pay a fixed monthly charge based on the size of their meter and a fixed volumetric charge based on the amount of water used each month
  • This blending of fixed and usage charges is intended to continue to promote conservation by giving people control over their bills by reducing their monthly usage.
