Household gas prices are rising by more than 10 per cent in major cities, saddling families with steeper energy bills despite a mandated pause in electricity tariff increases and a federal government cap on wholesale gas prices along the east coast.

AGL Energy, one of the country’s largest gas retailers, has notified customers in NSW of price increases to take effect on August 1, while Origin Energy and EnergyAustralia advised customers of price changes last month.
