Under energywatch's proposals, the government would make it mandatory for energy companies to provide a 'social tariff' for low-income customers. Equally, the government would have to work to help identify the neediest customers.
"Many of Britain's poorest consumers pay more for their energy because the market is indifferent to their needs," said Jonathan Stearn, head of campaigns for energywatch.
"Suppliers have made attempts at offering discounted tariffs for eligible consumers. But these offers are inconsistent and can be more expensive than the suppliers' own Direct Debit tariffs.
"Government and industry must work together to develop the foundation for fair pricing to vulnerable households for a service which is essential."
Recently, energy suppliers such as British Gas have cut their prices after wholesale costs fell.
