Energy efficiency and reducing your carbon footprint is important to many Anglian customers. To help you compare the effectiveness of each of our energy-efficient windows, we use the energy ratings system developed by the British Fenestration Rating Council (BFRC), which is the UK’s nationally recognised scheme for measuring windows' energy efficiency. The BFRC scheme is used in Building Regulations to show compliance for window replacements; to comply, every window must achieve a C rating or above.
Each window is assessed to measure how well it prevents heat loss, keeps draughts out and how well it absorbs natural, free energy from the sun. This combination of factors gives an overall energy rating, ranging from A+ to G, with A+ being the highest rating.
Our uPVC windows achieve an A rating or higher as standard, meaning they gain more of the sun's free energy than they lose through thermal transmittance. Ratings of A+ and A++ are also possible with our uPVC windows. Our A+ double-glazed option makes the most of solar energy, while our triple-glazed options – available up to an A++ – offer the best in reducing heat loss. By installing Anglian’s windows, you’ll be confident your home will be as warm as possible, while saving you money at the same time.
All our uPVC double-glazed windows achieve an A rating or higher as standard. The higher the rating, the more energy your windows save, which not only makes your home warmer, but helps to keep your heating bills lower. There are environmental benefits, too. By consuming less energy to heat your home, you’ll also be reducing your CO2 emissions.
Switching from single glazing to our A-rated energy-saving double-glazed windows will save money and significantly reduce heat loss. Even replacing older double-glazed windows to our modern A-rated double-glazed windows will make a difference. For all-round energy performance as well as other benefits, such as better soundproofing and security, you can choose triple-glazed windows, which also achieve up to an A++ rating.
Our A-rated windows are available in a number of styles, but for even greater energy efficiency, you can upgrade to A+ glass in some styles or opt for triple glazing, which is particularly beneficial for hard-to-heat rooms.

Key performance factors for energy rating
Energy ratings are calculated by measuring three performance factors:
1. Thermal transmittance, (U value) - This measures how well your window retains heat. The lower the amount of heat lost and U value, the warmer your home will be.
2. Solar, (G factor) - This evaluates how well your window harvests the sun’s natural heat. Expressed as a number between 0 - 1, the higher the number, the better your window is at capturing heat.
3. Air leakage, (L factor) - This measures how airtight your windows are. The lower the L factor, the less draughty your window will be.
The combination of these three factors provides an overall energy rating for each window.
We design every window with our three values in mind
Your security is of paramount importance, so at Anglian we manufacture windows to reflect this. Each window is made with robust multi-chambered uPVC with welded joints for added strength against forced entry.
All our windows achieve a high energy rating, with triple glazing guaranteeing maximum performance. With recent advancements in glass technology, our windows are more energy efficient than ever, saving you money on heating bills and helping to cut carbon emissions.
All our A-rated windows provide a sound protection level of 31dB, however our "Safe and Sound" range goes further for those living by busy roads, flight paths and railways.
