A customer we attended to this week in the eastern suburbs of Melbourne, asked a very common question…
How do I read the gas meter and make sense of it all?

Our customer was concerned about their gas consumption and the energy efficiency of their gas appliances. Most homes have their own gas meter. The gas meter is usually located towards the front of the home. In duplexes, flats or strata titled properties the gas meters can be located towards the front of the property and grouped together. In all situations it is good to know which gas meter is related to your home and it is clearly identified. It is useful to know the location of your gas meter because an isolation valve, which controls the flow to the gas meter, is normally located next to the gas meter. In an emergency, such as a gas leak in the fitting line or an appliance, you can isolate the gas supply to your home. It is a good idea to familiarise yourself with both the gas and water meter and their location. Also keeping both the gas and water meters clear of vegetation and accessible to the meter reader.



Some tips to understanding meter readings


Understanding how much energy you’re using can help you reduce your household greenhouse gas emissions.
If your meter only shows numbers, the black and white numbers show your reading (ignore any red numbers, we use those for testing).
If your meter shows several clock faces:

Gas meter readings

  • Use the left-most four clock faces only
  • Stand directly in front of the meter and record the number the ‘clock hand’ is pointing to.
  • If the hand is between two numbers, use the lower number – if it is between 0 and 9, use 9 as the reading.
  • Write down the numbers from left to right to get your reading.                                      

Calculating your usage

You can then calculate how much gas  you use in any set period the same way your network distributor does.


  • Don’t forget to read your meter at the start of the period and record the number.
  • Do the same at the end of the period you want to check.
  • Subtract the first number from the second number and you’ll see how much gas you used between readings.



Are far as the efficiency of your gas appliance goes, one way to check is the star rating sticker on the appliance.
The more stars the more efficient the gas appliance.
This sticker will also advise you of the amount of Mega Joules {Mj} the appliance consumes.
It is good practice to get your gas appliances serviced on a regular basis to ensure they are operating at maximum efficiency. This will also allow for any minor problems to be detected early and ensure the heater will be ready when you need it!
We hope this all makes sense !
