The energy market is broken, with millions of people paying more than they should. We’re urging the competition inquiry to reduce the number of people on poor value tariffs, make it easier to switch and penalise suppliers who fail to protect the most vulnerable. The CMA will be judged on the legacy of this inquiry - if it doesn’t deliver a fairer energy market for consumers, it will have failed.
