Reducing heat losses through windows will also have a positive effect on your heating costs. The Energy Savings Trust (EST) suggest that installing B rated windows instead of standard single glazed units could save around £170 per year on your energy bills.
Obviously, this depends on the size of your property but even so it’s a good saving if your windows need replacing anyway.
Other benefits of installing energy efficient windows include reducing your carbon footprint and making a more comfortable home.
The payback period for double glazing depends on a lot of factors such as what you are replacing as well as the cost of the windows being installed.
We recommend that you get quotes from several suppliers before choosing a replacement window company to ensure you get value for money.
