First, check to see if other gas appliances on your property are working. If they’re not, there could be an issue with your gas supply. In this case, please call your Gas Distributor.
If other gas appliances on your property are working, check your hot water unit’s pilot light. If you find that it’s gone out, search online for your manufacturer's instructions and follow these carefully to try and relight it.
If you’re unable to relight your unit’s pilot light, please call AGL on 131 766. We have an answering service that can help you outside business hours.
