Labour MP John Robertson called on the government today to change "outdated regulation" to raise the level of debt below which pre-paid meter customers may change their energy supplier.
Mr Robertson told the Commons altering the rules would ensure a "fairer system" was in place.
The Glasgow North West MP said that he was presenting the Pre-Paid Meters (Level of Debt) Bill "to get some actual movement" on the issue and wanted to see a change before winter and "before other people die because of their energy costs."
His Bill would require the Secretary of State to raise the level of debt below which pre-paid meter customers may change their energy supplier.
Mr Robertson hit out at the profits made by the big six energy companies arguing this was a time they should "give something back."
