The Winter Gas Concession provides concession card holders with a discount of 17.5% off gas usage and service costs during the winter period – 1 May to 31 October – each year. Details can be found here.
It does not apply to the first $62.40 of the six-month winter bills – this is covered by the Energy Supplement (see below).
If your gas bill is over the prescribed amount in the winter period 1 May to 31 October – each year, you will need to apply for the Excess Gas Concession (see below) to continue to receive a concession on your bill.
