A stricter code of practice on when prepayment meters can be forcibly fitted to recover debt have been announced by energy regulator Ofgem, following a temporary ban earlier this year.
However, campaigners are arguing that the the new measures don't go far enough to protect vulnerable households from having the meters installed against their will.
All energy suppliers have agreed to sign up to stricter rules for prepayment meters, following a report by Ofgem triggered by an investigation by The Times newspaper, which found debt agents acting on behalf of British Gas were forcing entry into the homes of vulnerable people.
