How much will I save on my energy bills by having double glazed windows fitted?

No matter what the age or condition, all properties lose heat through their windows. However, energy-efficient glazing is guaranteed to keep your home both warmer and quieter. And with less heat escaping out of inefficient, draughty windows, you are sure to save money on your energy bills.

How much might I save?

Of course, the exact amount of money you will save depends on a variety of factors, such as the type of window being replaced and the specification and quality of the window you have chosend to install. Figures do also fluctuate depending on the study you look at. However, it is a fact that installing good quality double glazing (B and above) is a great way to increase your home’s energy efficiency and reduce those expensive heating bills.

According to Which?, replacing your existing single-glazed windows with B-rated double glazing will see your energy bills drop by approximately £170 per year. Choose A-rated double glazed windows and you will save an additional 6.5%. The British Fenestration Rating Council (BFRC) is a lot more generous; it has reported that you could reduce your household bills by well over £400 per year if you install energy-efficient windows in your home.

Double glazing should last for at least 20 years, which based on the Which? statistics, means that you could see savings of at least £3400 in energy bills over their lifetime (not taking into account ever-increasing gas and electricity prices). Another study by a leading UK glazing company states that a typical semi-detached house that has single glazing replaced with A-rated double glazing will save £5,558 and 16 tonnes of CO2 over a twenty year period, with these savings factoring in a rise of 6% per year in gas costs to reflect typical annual inflation.

Additional benefits to installing double glazing

Energy-efficient double glazing also reduces condensation build-up on the inside of your windows, meaning less chance of damp and damage to your property.

Plus you will enjoy better security, which will not only provide you with additional peace of mind, but may see a reduction in the price of your home insurance when it comes time to renew your policy.

Couple these savings with a more comfortable home with less draughts and cold spots, added insulation to keep outside noise out and a reduced carbon footprint, and you will really see a difference.

Secondary glazing

Secondary glazing is a great, non-intrustive alternative to retrofitting new double glazed windows, particularly when it comes to old wooden houses, listed buildings and properties in conservation areas.

By inserting a second pane of glass onto or in an existing window, you can reduce heat loss and noise and enjoy much better thermal insulation. Dual Glaze has secondary glazing applications available for every type of window, including Vertical Sliders, Lift Outs, Balanced Vertical Sliders, Tilt-in Balanced Vertical Sliders, Hinged Units and Horizontal Sliders.

Please note that when it comes to properties in conservation areas, you must contact your local council’s Conservation Officer for relevant guidance before carrying out any work on existing windows to make them more energy-efficient.
