Double glazing is a popular energy efficiency measure and the English Housing Survey suggests that more than 85% of properties in England are fully double glazed, with less than 4% having no double glazing. As such, there is limited potential for further energy savings because so much of the stock already has efficient windows. Nevertheless, there are other benefits to more efficient glazing such as reduced internal noise, and improving the remaining single glazed windows would contribute to lower emissions.

The Government is committed to improving the energy efficiency of all homes. As part of reaching Net Zero by 2050, the Clean Growth Strategy set out that all homes should reach EPC C by 2035 where that is cost effective, affordable, and practical.
