Why is a BFRC Window Energy Rating Certificate Important for Homeowners?

The only way to measure the energy performance of double glazing in windows or doors is by stringent testing, which most people are unable to do themselves. These tests include complex measurements that are put together by the British Fenestration Rating Council (BFRC) to create a rating. The ratings are based on average window size, building occupants, and the UK’s climate.

A few of the pertinent performance ratings that the BFRC’s rating scheme uses include the following performance metrics, which are an important part of any product assessment:

• Solar gain, which is how much heat a window might generate inside the room from the sun
• Thermal loss, which is how much heat a window might lose inside the room to the outside
• Air tightness, which is the amount of hot or cold air that leaves the inside of the room or comes in from the outside

As by far the UK’s most trusted rating’s council, the calculations can then be used to issue a certificate on BFRC rated products, which proves how energy efficient windows are. As a result, a BFRC window energy rating certificate is a reliable signifier of a quality window for homeowners.
As leading providers of double-glazed windows with various ratings, we understand the nuances of the system. Here we will explain a bit more about how it works and why it is useful to people. You can fill out our short form for a free quote on windows across the south coast of the UK.

What BFRC Window Energy Rating Certificates are There?

The rating itself is a little sticker or label on the product itself or associated documentation. The scale is also called the ‘rainbow rating’ and goes from A++ to E. BFRC energy-rated products are present on almost all products available and is the most widely-used energy rating in the UK.

The main benefits of getting a window or door that uses a WER certificate include:

1. Easy to understand:
   The complex measurements regarding heat loss, air leakage and other precise tests can be difficult for a homeowner to understand, so a simple rating system from A++ to E makes it plain to any person what is the best or better option.
   
2. Independent certification:
   You will not have to lay your trust in a manufacturer with BFRC ratings. As an independent rating council for verifying all manufacturers, there is never any vested interest in the performance of a particular brand or type of window.
   
3. Reliable performance:
   Because of the rigorous testing of each product you can be sure that the windows will perform as the rating indicates. Provided you use a trusted installation company such as ours, the windows will work exactly as the rating states.

With this information at hand, a person can more easily assess what windows will work best for them. For example, if a person is unsure of what window to buy for their home but has narrowed it down to two or three products they can use the WER to select the right ones for their needs.

As a BFRC window energy rating certificate is UK-specific, it is also excellent for installers – as it demonstrates that the product is compliant with current building regulations. The BFRC has an association for the top accredited window installers, and we are members of this association.

The BFRC ratings and certificates are also excellent for the manufacturers of windows. They can easily demonstrate the quality of their products and also make products at various price points or designs by looking at the WER of their main competitors, so it is good for all parties involved.
