How to work out how much double glazing can save on your energy bills

Every year, homeowners across the UK spend hundreds of pounds keeping their properties warm. During the winter months, energy bills can go through the roof as plunging temperatures and poorly- insulated buildings take their toll on the country’s bank balance.

If you’re trying to reduce the amount you spend on heating your home, and make your household a little greener in the process, installing double glazing is the perfect way to achieve this. Dramatically boosting the efficiency of your home, and helping you keep warm air firmly inside your property, double glazing will help to give you the cosy interior you’ve always wanted. So, how much exactly can double glazing save you on your energy bills? We decided to find out.

Calculating your savings

There are lots of factors that will affect the saving you make when you install double glazing. For example, if you’re replacing old double glazing with new, more efficient windows, you won’t save as much as you would if you were replacing single glazed panes. If your home has a poorly insulated roof or draughty doors, this will also limit the savings you make on installing double glazing.

According to @MoneySupermkt, “If your detached home is entirely single glazed, you could save as much as £160 a year by installing A-rated double glazing.” To get an idea of how much you’ll save, ask your window manufacturer for the energy rating of your chosen windows and then compare that to your current panes. This should give a good indication of how much more efficient your new windows will be.  

What you need to check before installing double glazing

Before installing double glazing on your property, there are a few things you need to consider. If you live in a conservation area, you may not be able to swap your old windows for energy efficient new ones. If you are allowed to replace your panes, there will probably be strict rules in place about how your new windows should look and the materials they should be made from.

Likewise, if your property is listed, then you’ll need to get permission before making any modifications that will alter the look or structure of the building. Talk to your local council to find out what’s permitted in your area.

Installing double glazing in your home

In order to get the most out of your double glazing, it needs to be installed by a professional. Even miniscule gaps around the window pane can dramatically reduce its effectiveness, so make sure yours are properly installed by hiring an experienced professional to do the job.
