Scottish and Southern Energy will raise its domestic energy prices by an average of 14.2% for electricity and 15.8% for gas. The company is the last of the big energy suppliers to announce a price increase, following announcements by Npower, EDF Energy, Scottish Power, British Gas and E.On. They blame the increases on the rise in wholesale energy prices. The increases mean an average electricity bill will rise by £50 whilst a gas bill will increase by around £85.
