Energy Rated

At Sanderson Brothers (Inglewhite) Ltd we are a registered member with The British Fenestration Rating Council (BFRC).

The British Fenestration Rating Council Limited (BFRC) window rating system meets this need and allows consumers to rapidly compare the energy efficiency of different products. Windows are rated using a familiar A to G scale on the basis of their total energy efficiency, where an A-rated window is more energy efficient than a G-rated window. Consumers can quickly and easily choose the most suitable window for their needs. The BFRC is an independent body that controls energy rating of windows as part of a European scheme.


The windows that we select for our homes bring light, warmth, and beauty into them. Poorly selected windows are a major source of heat loss in the winter and can reduce comfort and the amount of effective living space. Energy efficient windows, when correctly selected and installed, will help to minimise the heating and lighting costs and will also increase comfort and the amount of useable living space. In the past, selecting energy efficient windows has been difficult for consumers and there is a need for a method of selecting energy efficient windows that is both easy to understand and independent.


All of the door and windows are certified to the PAS24 security standard. This can only be achieved after a product has been thoroughly tested and assessed for high security performance levels. This certification gives you piece of mind that your home is secure, while also adding value to your property.
