Consumer trust in the energy industry has plunged to a new low amid the furore over soaring bills, new research has shown.
A survey by Which? revealed that consumers had more faith in banks, car salesmen and train companies than in energy firms.
The poll of over 2,000 adults found that more than four out of five were worried about energy prices, with most cutting back on heating and almost half fearing they could be forced into debt as a result of rising bills.
Which? urged the Government to do more to tackle energy costs following the announcement of reforms including making it easier to switch supplier.
Which? executive director Richard Lloyd said: "The number of people worrying about energy prices has rocketed, while trust in the companies has plummeted.
"What we have heard from the Government so far is too little, and too late, for the millions of hard-pressed consumers worrying how they will pay for their energy bills this winter. Consumers need to see radical changes now.
"George Osborne should use his Autumn Statement to cut the Big Six down to size by separating the wholesale energy market from domestic supply, and by cutting the cost of Government energy policies to consumers."
