Your Consumption

Your meter will measure the volume of natural gas delivered to your property. Your current meter reading (or estimate), minus your previous meter reading equals your volume of gas consumed in cubic metres (or centa-cubic feet) for the current period.

Liberty will convert the volume consumed into energy consumed using a Gigajoule (GJ) Conversion Factor. This factor represents the average energy content contained in each cubic metre (or centa-cubic feet) of natural gas. The conversion factor used for each bill will be based on the average daily energy content of natural gas received during the billing period.


If, for any period, a meter fails to register the quantity of gas supplied, then the quantity supplied during the period will be estimated based on the average daily volume registered by the new meter, or on the quantity of gas previously used during a corresponding period in the previous year.

Late Payments

Payments must be made in full no later than the due date shown on your bill. A late payment charge of 1.5% will be applied to any outstanding balance after the due date.
