Martin Lewis has called on Energy Secretary Ed Miliband to overhaul the smart meter rollout, highlighting significant issues with faulty devices. Surveys indicate that around 19% of smart meters in use are malfunctioning, a figure much higher than the government's estimate of 9%. Complaints from consumers include inaccurate billing, unresponsive displays, and top-ups not registering. Lewis argues that the focus should shift from installing new meters to repairing existing ones to prevent billing errors and consumer frustration. Official data shows that 4.31 million smart meters are currently faulty, with the rollout costing over £13.5 billion. Despite the intent to save on energy bills, the programme has been criticized for its poor execution and slow repairs.
