A Downing Street spokeswoman said they welcomed Ofgem's new proposals to force companies to tell customers about their cheaper tariffs:
We welcome the proposals that Ofgem have set out today. Their proposals will help make bills simpler and easier for consumers. This is complementary with what we are trying to achieve. It is really the same agenda. We have been working with them for some time on this and will continue to work with them. As the Prime Minister said, we will use forthcoming legislation to ensure that people get the lowest tariffs. The Energy Bill will be published in due course and we will take into account the Ofgem proposals.
