Tackling our least energy-efficient homes is an absolutely key priority here at the Energy Saving Trust, and we're delighted that our new report – published yesterday – shows that we can make a massive improvement to the worst of them for under £3,000 on average.

The message seems to be getting through, too, as the story's been taken up by key media including the Guardian, Google's hosted news (via the Press Association) and MSN.

Now, we realise there is a lot to do. Is getting F & G homes to an E banding enough to hit our 2050 80% carbon reduction target? Of course not, but it will take us a step
along the way. It’ll also help protect the health and monthly outgoings of a lot of
people living in cold homes.
The Energy Saving Trust wants to see as many existing homes as possible being brought straight to an A or B standard. That's why, as well as research into the least energy efficient homes, we work so hard providing guidance on advanced low-carbon refurbishment!

The real message we're getting across today is that, where the least energy-efficient homes can emit over 22 tonnes of carbon dioxide a year, bringing these up to an E rating would save 14 tonnes of C02 for each home, every year. (By comparison, a very average British home emits five tonnes of CO2.)

And the really good news is that, even among these worst F and G-banded homes, quite a few could be brought to Band E for well under £1,000, just by insulating the loft.

In 2008, 17% of English homes were in the F and G bands. In 2006 it had been 22% – so, as our report on F and G-rated properties shows today, we are moving in the right direction.
