Details released today (July 17) show only 57% of Britain’s lofts have been properly insulated and only 58% of cavity walls have been filled.

The latest figures released by the Department for Environment and Climate Change (DECC) reveal the average UK household could save around £100 a year on energy bills.

DECC research also shows 479,000 professional insulation measures have been installed, against a new target of more than 3 million installations planned before the end of 2012.

Energy and climate change secretary, Chris Huhne, said: “At a time when money is tight and with energy prices predicted to rise, householders are missing out on over £100 of savings every single year by not getting their lofts lagged and cavity walls filled.

“We are making energy companies do more to help their hard pressed customers, with another 3.5 million households set to be protected against higher bills by the end of next year.”

People who want advice on insulating their home should call the Energy Saving Trust on 0800 512 012 to find out about the latest local offers on insulation available.
