The energy price cap is predicted to drop below £3,000 as early as April by the boss of Ofgem with possibly even more savings to come in the summer.
Jonathan Brearley said that it was "possible" that falls in the wholesale cost of gas and electricity could mean that bills would fall below that level for the average household.
It is more optimistic than recent projections from independent analysts at Cornwall Insight, who last week forecast the price cap would still top £3,200 in April before falling significantly in July.
