A minister has urged hard-hit energy customers to "vote with your feet" in the event of high fuel bills. The Bank of England has warned it expects household energy bills to rise by 15 per cent this year. "Consumers don't have to take price increases lying down. If an energy company hits you with a price increase, you can hit them back where it hurts — by shopping around and voting with your feet," Energy Secretary Chris Huhne told the Observer newspaper.
