NPower boss Paul Massara has caused controversy after claiming that energy bills in Britain were so high because home owners "waste so much energy."
In a report entitled "Energy Explained," Mr Massara also stated that British houses were old and draughty, and that the unit price of energy in the United Kingdom was one of the lowest on the continent.
He said: "If we can increase the energy efficiency of the UK's old and draughty housing, we can ensure that annual energy bills are some of the lowest too."
The comments of the nPower chief executive follow criticism of energy supplier bosses from MPs for their conduct during the bad weather over the Christmas holidays, which left around 150,000 homes with no power.
John Robertson, a Labour MP, responded directly to Mr Massara's claims by stating: "Once again, we see an energy baron blaming everybody but themselves for eye-watering and unfair price rises. It is all very well for nPower bosses, with their massive salaries and bonuses, to blame their customers for bad insulation in their homes.
"But a huge proportion of their customers, including the elderly, disabled and more vulnerable, are struggling to pay for their heating in the first place, never mind paying to insulate their walls, roofs and boilers. Perhaps nPower bosses could use some of their excessive profits to pay for the insulation," he concluded.
Last year (2013), nPower - one of the big six energy suppliers - implemented an average price rise of 10 per cent, which impacted around 3.1 million of German-owned supplier's customers. However, it has since announced that bills will be reduced in light of changes to the way the Government collects green levies.
