Ever wondered how much energy – and money – you could save by replacing your current windows with more energy-efficient ones?

Now it’s easy to find the answer thanks to the GGF Energy Savings Calculator. Newly launched by the Glass and Glazing Federation (GGF), it’s the easy way to see the potential financial and environmental benefits of upgrading the windows in your home.

Calculate your potential energy & cost savings

Installing windows with a higher energy rating can reduce the amount of energy required to warm and cool your home, as well as helping to make it a healthier and more comfortable place to live in.

The GGF Energy Savings Calculator lets you calculate what this could save you over the years to come as a result of reduced energy usage.

How it works

Simply select the options that describe your current windows, your dwelling type, your heating fuel and your proposed replacement windows to calculate the potential savings you could make.


This will tell you how much you could save in terms of energy costs, CO2 emissions and carbon usage each year.

You can also enter what you expect to spend on replacement windows to see how quickly your investment is recouped in the form of power bill savings.

Make an informed decision
