Vulnerable households face an “inevitable new winter crisis” without more help on energy bills, a group of MPs has said.
They called on the government, regulator Ofgem, and energy suppliers to take urgent action.
People are being squeezed by cost of living pressures and debt, the MPs on the Commons select committee added.
Industry group Energy UK said suppliers had been increasing support at “a very difficult time for its customers”.
In a report, the MPs on the Energy Security and Net Zero Committee said that the government had provided “unprecedented levels of support” last year when it stepped in to help with soaring energy bills.
