The most recent data from the English House Condition Survey shows that in 2007, 67% of homes had full double glazing and 11% had no double glazing, with the remainder part double glazed. Moving a typical home from no double glazing to full C-rated double glazing would save 430 kgCO2 per year and save the household £85 per year.
