I was just flicking through some bills for a relative and it turns out the electricity provider hadn't applied the Annual Electricity Concession for almost a year - she otherwise wouldn't have noticed, so just a reminder to make sure you're still getting the discount if you're eligible as sometimes systems can just glitch.
When we contacted the provider they were quite surprised that we were eligible for the concession but hadn't actually received the discount and we had a set of bills readjusted for the past year so it's definitely worth just checking.
You have to resubmit your concession every year when you concession card expires in most cases.
Gas concession is only during winter
