My hon. Friend raises a very important question for many people in this country. I am glad to tell him that there has been good news. Since 2010, the number of energy suppliers has gone from 13 to more than 60 and 7.8 million energy switches took place in 2016, an increase of nearly 1.7 million on 2015. That means that customers are saving an average of around £308 by switching from a standard variable tariff offered by the big six. He will be aware of our commitment to bringing forward an energy price cap Bill, and that will happen in the near future.
