LABOUR’S pledge to cut energy bills was left in tatters today after regulator Ofgem announced consumers will be slapped with yet another increase in January. 

The energy cap is set to rise by 1.2 per cent this winter, pushing the average household energy bill to £1,738. 

It comes after the regulator imposed a 10 per cent rise last month, intensifying the financial strain on 6.5 million households already grappling with fuel poverty.
