Replacing your windows and doors isn’t just about improving the look of your home—it’s an investment in comfort, cost savings, and sustainability. With rising energy costs (Energy Saving Trust), homeowners are looking for ways to keep their homes warmer in winter, cooler in summer, and more energy-efficient all year round.

At Abbey Windows Leicester, we manufacture and install high-performance uPVC windows and doors, designed to reduce heat loss, lower energy bills, and make homes more environmentally friendly. Using Deceuninck’s uPVC frames and Pilkington KS glass, we ensure homeowners get the best combination of insulation, durability, and style.

Why energy-efficient windows matter

Windows play a critical role in your home’s energy efficiency. Poorly insulated windows allow heat to escape in winter and let excess heat in during summer, making it harder (and more expensive) to keep your home at a comfortable temperature.

By upgrading to modern A-rated double glazing, you can reduce heat loss and cut down on your energy consumption, leading to noticeable savings on your heating bills.

What is A-Rated double glazing?

Windows in the UK are rated for energy efficiency on a scale from A++ (most efficient) to E (least efficient), similar to the ratings found on household appliances. A-rated double glazing means the windows have been tested and certified to provide excellent insulation, helping to retain heat in winter and keep unwanted heat out in summer. This leads to lower energy bills and a more comfortable home environment.

Deceuninck uPVC Frames: Designed for better insulation

One of the most effective ways to improve your home’s thermal efficiency is by choosing high-quality uPVC window frames. We use Deceuninck’s multi-chambered uPVC frames, which act as built-in insulation barriers to trap heat inside your home and keep cold air out.

Unlike older window frames made from aluminium or wood, Deceuninck’s modern uPVC designs are highly energy-efficient, maintenance-free, and fully recyclable—making them an eco-friendly option, too.

Pilkington KS Glass: Keeping your home warmer for less

The type of glass used in your windows is just as important as the frame. Pilkington KS glass is a high-performance low-emissivity (Low-E) glass, featuring an invisible coating that reflects heat back into your home.

The benefits of Pilkington KS Glass:

✅ Reduces heat loss in winter, keeping your home warmer

✅ Helps prevent overheating in summer by limiting solar heat gain

✅ Allows natural light in without compromising energy efficiency

With Pilkington KS Glass, you can enjoy a more comfortable home environment while reducing the amount of energy needed for heating and cooling.

How much can you save on energy bills?

According to the Energy Saving Trust, upgrading from single glazing to modern, energy-efficient double glazing could save a typical UK household up to £195 per year on heating costs.

Even if your home already has older double glazing, replacing it with the latest energy-efficient designs can make a noticeable difference in:

💷 Lowering your heating bills

🏡 Creating a more comfortable living space

♻ Reducing your carbon footprint

The environmental impact of energy-efficient windows

Choosing energy-efficient windows and doors isn’t just about saving money—it’s also a significant step towards a greener, more sustainable home.

🌱 Lower Carbon Footprint – By using less energy for heating and cooling, energy-efficient windows and doors help reduce CO₂ emissions, contributing to a smaller environmental footprint. For example, upgrading to double glazing could reduce your home’s carbon footprint by as much as 680kg of CO2 per year, based on typical UK energy usage. (Energy Saving Trust)

♻ Sustainable Materials – Deceuninck’s uPVC frames are 100% recyclable, making them an eco-conscious choice for homeowners looking to make a positive environmental impact. By choosing sustainable materials, you’re contributing to the circular economy and reducing landfill waste.

💡 Less Energy Waste – A well-insulated home requires less artificial heating and cooling, reducing overall energy consumption. Energy-efficient windows keep heat where it belongs, inside your home, helping to avoid the need for excess heating during colder months and air conditioning during warmer ones.

By installing energy-efficient windows and doors from Abbey Windows Leicester, you’re not only improving the comfort and efficiency of your home but also helping to reduce your household’s environmental impact.

Not ready for new windows? Here are some steps you can take

If you’re not quite ready to upgrade to energy-efficient windows, there are still several things you can do to improve your home’s energy efficiency. Simple solutions like adding thermal curtains, using draft excluders, or sealing gaps around your current windows can reduce heat loss and improve comfort. Additionally, window film can be applied to enhance insulation and block UV rays, helping keep your home cooler in the summer and warmer in the winter. These cost-effective measures can make a difference while you save up for a more permanent upgrade.

If you’re considering upgrading in the near future, Abbey Windows Leicester also offers finance options, subject to status, to help make the process more affordable and manageable.
