A group of more than 70 organisations has written to the Energy Security & Net Zero (ESNZ) committee urging it to investigate the recent decision to grant Scottish Power warrants to forcibly install prepayment meters (PPMs). The End Fuel Poverty Coalition raises a number of concerns about the fact the supplier has recently successfully applied for PPM warrants after a moratorium on forced PPM installs was agreed on earlier this year, following serious concerns about supplier malpractice.
