Martin Lewis, the country's favourite Money Saving Expert, has urged the public to check their gas and electricity meters on March 31.
Energy bills are set to surge on April 1 as regulator Ofgem has confirmed it is increasing its price cap by 54% - rising by an eye-watering £693 from £1,277 to £1,971.
