Ofgem has accepted Grant Shapps' call to set up a channel for households to pass on their own feedback on how they are being treated by suppliers rather than relying on firms to share such information. The energy secretary's demand came as he issued another rebuke to energy retailers over concerns about the treatment of prepayment meter (PPM) customers. He said companies had complied with his request for more information on forced PPM installs but accused some of providing only “half the picture” on the steps they are taking to ensure the most vulnerable are protected.
