The average household could save £150 a year if only they knew of the better deals their current suppliers were hiding from them, according to Moneysupermarket.com.
The company is calling for firms to notify their existing customers when they launch better deals.
Paul Schofield, head of utilities at Moneysupermarket.com, said: “Energy providers rarely, if ever, tell existing consumers about cheaper deals, as the more expensive tariffs allow them to offset the great deals they offer.”
“Allowing customers to languish on old tariffs is a money-spinner, but it doesn’t help build trust or loyalty,” he added.
Energywatch, the industry watchdog, supports the call to get suppliers to make more of an effort to promote cheaper deals.
Graham Kerr, energywatch spokesman, said: “Surely it’s good business sense to try to retain the customers a company already has. If providers introduce new and innovative deals, offering them to existing customers gives them an incentive to stay rather than switch to a separate company.”
However, the Energy Retail Association (ERA), who represents suppliers, said that the UK market was already “fiercely competitive”.
Duncan Sedgwick, chief executive of the ERA, said: “Energy suppliers spend millions of pounds each year advertising new products to customers in order to compete effectively with other players in the market.”
He added that comparison services had an important role in making sure that the better tariffs were “always in the public eye”.
