The Partnership's findings will make perturbing reading for government ministers who vowed to abolish fuel poverty by 2016.
"Many people from low-income backgrounds are now faced with the unenviable choice of deciding whether to heat their homes or provide for their family," Partnership spokesperson Nicholas Doyle said.
