My yearly Kwh usage for gas and electric?

As title says, how do I find out easily?

The easiest way is just to look at an old meter reading (will be on old statements), and compare it to a new meter reading.

With gas you’ll have to apply a conversion factor to get kWh but I belive the statements tell you what it is.

You last statement/bill from your previous supplier should possibly show the annual kWH.
