UK Green Building Council chief executive Paul King said: “The prime minister should be in no doubt that these shocking figures are a direct result of how poorly insulated our homes are.
“If there is any rolling back of energy efficiency schemes such as ECO in the Autumn Statement, these disgraceful numbers are only going to get worse. How much more obvious could that be?”
