With energy bills still high in 2025 and the cost of living continuing to affect families across the East Midlands and the wider UK, many homeowners are actively searching for how to make their home more energy efficient. The more effectively your home retains heat, the less you spend on heating and one of the most impactful ways to achieve this is by upgrading your windows and doors.
In this guide, we’ll walk you through how to make your home more energy efficient, starting with the biggest sources of heat loss and the improvements that deliver the greatest long-term savings.
Why Learning How to Make Your Home More Energy Efficient Starts with Windows and Doors
If you want to understand how to make your home more energy efficient, you need to look closely at the parts of your home responsible for the greatest heat loss. In the UK, older windows and doors are among the worst offenders.
Single-glazed windows, worn frames and ageing seals allow warm air to escape and cold air to creep in, forcing your heating system to work much harder. Similarly, draughty old doors with deteriorating seals can lead to noticeable temperature drops and higher energy consumption.
Replacing these outdated features is one of the most effective steps you can take toward creating an energy-efficient home.
How Upgrading Your Windows and Doors Helps Make Your Home More Energy Efficient
Upgrading your windows and doors does far more than improve appearance. Modern glazing and insulated frames dramatically reduce heat loss and help maintain stable, comfortable temperatures year-round. This results in lower energy bills, reduced carbon emissions and a warmer, quieter home.
Best Energy-Efficient Windows for Reducing Heat Loss in Your Home
If you’re serious about making your home more energy efficient, the type of window you choose plays a huge role in reducing heat loss. At KLG Rutland, our uPVC windows are one of the most popular choices for East Midlands homeowners thanks to their exceptional insulation, long-term durability and low maintenance needs. Their multi-chambered frames help trap warmth, while advanced double or triple glazing significantly reduces energy transfer.
If maximum insulation is your goal, our triple glazing offers the highest level of thermal performance. With three panes of glass and two insulating cavities, triple glazing significantly reduces heat loss, improves sound insulation and enhances security, ideal for exposed locations or colder climates.
Why Composite and uPVC Doors Are Essential for an Energy-Efficient Home
Your home’s doors are just as important as your windows when it comes to preventing heat loss. Our composite doors are constructed with a GRP exterior and a dense, insulating polyurethane core, a combination that provides exceptional thermal efficiency, durability and security. These doors help maintain a warm, comfortable home even on the coldest days.
For a practical option, our uPVC bi-fold doors offer impressive insulation and weather resistance thanks to their multi-layered construction and high-quality seals. They’re available in a range of modern designs, making them a popular choice for improving both energy efficiency and brightening up a space without compromising warmth.
If your priority is a premium, sleek aesthetic, our aluminium bi-fold doors deliver outstanding performance with a contemporary finish. Their frames minimise heat transfer and help maintain comfortable temperatures throughout the year. These doors are particularly suited to modern homes or properties featuring large glazed areas.
What to Consider When Choosing Energy-Efficient Windows and Doors for Your Home
To get the best results from your new windows and doors, it’s important to consider:
- Orientation: North-facing windows generally lose the most heat, making them a priority for upgrading
- Climate and exposure: Homes in windy, exposed or elevated areas need more robust insulation
- Budget: While high-quality windows and doors are an investment, the reduction in energy bills and increase in property value make them highly cost-effective over time
Our experts can help you choose the most efficient products for your home’s specific needs.
Additional Ways to Make Your Home More Energy Efficient for 2026
Once you’ve addressed heat loss through windows and doors, there are several additional steps you can take to further improve your home’s efficiency and lower your energy bills.
Air Source Heat Pumps
Air source heat pumps extract heat from the outside air and transfer it into your home, offering far greater efficiency than traditional gas boilers. They help reduce heating costs and carbon emissions, making them a smart long-term upgrade.
Solar Panels
Solar panels generate renewable electricity directly from sunlight, reducing reliance on the national grid. This can significantly lower your electricity bills, and in some cases, households can even sell surplus energy back to the grid.
Cavity Wall Insulation
Cavity wall insulation prevents heat from escaping through external walls and helps maintain a consistent indoor temperature. Older homes, in particular, benefit greatly from having cavity or loft insulation installed.
Why Energy-Efficient Appliances Help You Save Money and Reduce Energy Use
Switching older appliances for modern, energy-efficient models can make a big difference to your home’s overall energy consumption. From washing machines and tumble dryers to ovens and fridges, new appliances are designed to deliver high performance while using less electricity, saving you money over time.
