Energy Efficient Windows: Maximise Your Comfort and Cut Your Bills

In these days of high gas and electricity bills, any step that helps you to cut down on the amount of energy you use is well worth exploring. 

One way to cut those bills is to install energy efficient windows that work to retain more of the heat you generate inside your home. 

The links between windows and energy efficiency are clear – and, by investing in made-to-measure windows that are installed by trained professionals from a respected supplier such as Hugo Carter – you can enjoy the benefits that such a move will bring.

Energy conserving windows can play a key role in reducing the amount of fuel you consume. In any building, a large proportion of the heat that escapes does so through the windows.

By making sure that your windows are as energy efficient as possible, you can create a more cost-efficient and eco-friendly home for you and your family.

Understanding Energy Efficiency

Every home that comes up for sale in the UK should have an EPC – an Energy Performance Certificate. This rates the energy efficiency dwelling, and a high rating can be an attractive feature in the eye of many buyers.

The best energy efficient windows can make a significant difference in this respect. Windows expertly constructed from sturdy materials have been proven to cut down on the amount of heat that escapes from a home.

The less efficient your windows are, the more energy you need to use to keep your home warm – and the higher your utility bills will be.

By contrast, if you install energy saving windows, you should be rewarded for living in a more eco-friendly and efficient home by a reduction in the cost of heating it.

Key Features of Energy Efficient Windows

There are several elements in the design of energy efficient double glazing that contribute to their ability to reduce home owners’ utility bills.

The first is the materials used. At Hugo Carter, all our windows are constructed using slow-grown timber, which is robust and impermeable. Less heat is transferred through timber frames than those constructed from alternative materials such as uPVC.

You can also fill the gap between panes in your double glazing with argon gas, which is an excellent insulator and allows less heat to escape.

Another factor that makes double-glazed windows energy efficient is the inclusion of low-E glass in their construction.

Low-emissivity glass, to give it its full name, has a coating which ensures less heat is allowed through from inside your property to the outside. You can learn more about low-E glass and how we use it here.

A key element in our double glazing energy-saving windows is the quality of the team that constructs and installs them. We take care to measure every window as precisely as possible so that it fits perfectly and represents an energy efficient double glazing solution.

Financial Savings & Return on Investment

The amount of money that you might recoup by installing heat-saving windows will vary depending on the size and location of your property. However, the average home owner could save up to £200 annually by switching to good energy-efficient windows.

Over time, that saving will ensure a healthy return on the investment you make in commissioning Hugo Carter to create a set of the highest rated energy efficient windows for you.

Energy efficient windows will also contribute to a higher rating on your Energy Performance Certificate, which could make your house more attractive to potential buyers if you decide to sell.

Environmental Impact

So far, we’ve looked at the positive difference it makes to your energy bills when you reduce heat loss through windows. But there are other compelling reasons for installing energy efficient windows.

Releasing less heat and carbon into the atmosphere from your home ensures you are contributing to the battle against climate change. Consuming less fuel in the process is also an eco-friendly step to take.

In this context, you might be interested in the U-value of the windows you install. This is an expression of the amount of heat allowed to escape through a window. Low U-Value windows are, therefore, a good choice if you want to keep more energy within your property.

Choosing the Right Energy Saving Windows

How do you select the right set of energy saving windows for your property? There are several factors to consider, some of which will be determined by the condition of your home, and its location.

If it’s in a conservation area, for instance, you will need to comply with local building regulations – a process in which the team at Hugo Carter has immense experience. If your property is in a particularly cold part of the world, you may need extra levels of protection and be keen to install the best-rated energy efficient windows available.

Our engineers will be able to advise you on the most appropriate installation with regard to your situation and your aspirations.

We’ll guide you through the various window styles available when you want to focus on energy saving by sourcing our top-rated energy efficient.

The high-performance windows at the top of the Hugo Carter range offer exceptional levels of energy efficiency, but all of the window styles in our range can be customised to your needs.

Installation and Maintenance Tips

We cannot emphasise strongly enough that, to get the maximum degree of energy efficiency from your windows, you should have them constructed and installed by a team of professionals.

At Hugo Carter, we make every window to the most precise measurement. They are fitted by an installation team with extensive experience in delivering windows that work beautifully with their surroundings – and are incredibly energy efficient.

Building your window will take us between 10 and 14 weeks, and we will keep you updated throughout the process. We’ll also let you know two weeks in advance when installation will take place.

We can make a maintenance visit to ensure your installation is providing the efficiency you ordered, but you can play your part too in keeping your new windows in tip-top condition. 

Clean the frames and glass regularly, make sure the seals are as tight as they can be, and repair any cracks or blemishes in the frames.

Energy Efficient Window Innovations

It’s an old cliché that necessity is the mother of invention. And at a time in human history when we need innovations that combat climate change and help the environment, there are numerous ways in which energy efficient windows are becoming even more efficient. 

At Hugo Carter, we pride ourselves on the quality of our service – but we are always looking for ways to improve. That keeps us interested in the cutting-edge technologies that are always being developed in the field of energy efficiency. They include:

Low-E glass

This surface offers you the ability to adjust the transparency of a window. You can also use them to reduce the amount of energy spent in lighting your home, which makes them an eco-friendly and cost-effective solution.


What type of window is most energy efficient?

A professionally fitted one. The best step you can take to make your windows energy efficient is to ensure they are created, constructed and installed by a team as experienced and knowledgeable as Hugo Carter’s. We can also advise you on the type of window that will be most appropriate for your property in this context.

What is the most energy-efficient glazing?

It’s important to use high-quality glass in all your windows. But you can increase the energy efficiency by making sure the U-Value of your chosen solution is as low as possible. You can also request low-E glass to cut down on heat loss, while argon in the space between double-glazing panes also increases the amount of heat retained within a property.


What are the best low-energy windows?

There are various models across Hugo Carter’s extensive range that can be customised so that they are as energy efficient as possible when installed in your home. If this is a priority for you, check out the high-performance windows at the top of our range that deliver exceptional levels of performance.

Can I get a grant to replace my windows?Can I get a grant to replace my windows?

Possibly. It is worth exploring the schemes through which you might receive some support with the cost of energy efficient windows. Although there are no official government schemes, check out the ECO4 programme, the Home Upgrade Grant scheme for English homes, and Warmer Homes Scotland if you are north of the border.


The most compelling reason for you to install energy efficient windows may be that you like the idea of reducing your energy bills by hundreds of pounds over the years to come.
