Why does energy efficiency matter when buying replacement windows?
If your windows do not perform well at keeping warm air in or blocking outside chills, you will find that you need to heat your house more in order to maintain it at a warm and comfortable level. However, energy-efficient windows are designed to stop warm air from escaping whilst keeping out draughts, so you will be less reliant on needing to put the heating thermostat up. Ultimately, this means you can save on your energy bills, so good-quality windows can be a sound investment for your home.
How do you know if a window is energy-efficient or not? Many industry bodies and federations help consumers to understand the energy efficiency and performance of their windows by rating them. In particular, when choosing replacement windows, keep your eyes open for BFRC, which awards the performance of windows with a WER Rating.

Windows can be rated from A to G, with A being the best. Windows that have been awarded an A rating also achieve a number based on performance. A10 translates as an A+, for example, and anything above this will get an extra number after the plus.
