A mother-of-two said her financial situation had become “exponentially worse” after a prepayment meter was installed at her house.
Lisa Jefferies-Wilkin, 39, from Kettering, Northamptonshire, faced a threat of court action from Scottish Power if she did not install the meter, after falling behind with payments.
“I’m in a hopeless situation. I don’t know what I can do,” she said.
Scottish Power said the installation of meters was enforced as a last resort.
Research suggests the energy crisis has pushed more UK households on to prepayment gas and electricity meters, with 60,000 new meters installed in the six months to March.
