Energy watchdog Ofgem has been accused of letting suppliers resume targeting vulnerable people for the force-fitting of prepayment meters.
Ofgem yesterday announced a voluntary code with suppliers, but charities and politicians said glaring loopholes would leave many people at risk.
Caroline Abrahams, of Age UK, said: “These rules do not go far enough. The risk is some older people, and younger ones, who should definitely not be on a prepayment meter end up on one.”
