I agree with my hon. Friend. One feature of the energy market is that the poorer someone is, the larger the proportion of their income that they spend on energy. That is why it is imperative that vulnerable consumers should not be required go on the internet every few months to check that their tariff has not defaulted to a much higher one. That was the reason for my letter to Ofgem, and it is why I want its response to be vigorous. My hon. Friend is absolutely right that an aspect of the wider set of policies is to make it easier for consumers to know the price of energy and how much they consume, and smart meters are being introduced to help more people to do that.
