The GGF Energy Savings Calculator only provides an estimate of potential savings as a result of installing energy-efficient windows.
The calculator assumes the homeowner has taken all other practical measures to optimise the energy efficiency of their dwelling. Such measures may include cavity wall and loft insulation, as well as the installation of an energy efficient heating system.
For more information, advice or a quote for installing energy efficient windows in your home, we recommend contacting a GGF Member company.
