Martin Lewis has warned people claiming State Pension could lose one third of their annual benefit on energy bills.
The UK is currently facing a cost-of-living crisis as energy bills skyrocketed by 54% in April when Ofgem lifted the price cap. The increase has meant the typical bill has surged from £1,277 to £1,925 a year.
Ofgem's chief executive said in late May that a typical household would pay £800 a year more from October. However, Jonathan Brearley has now warned the price of energy bills in winter is predicted to rise faster than expected.
