The most energy-efficient windows are A++ rated by the British Fenestration Rating Council. Always look for an A++ rating when buying double glazed windows to ensure the best possible results.

Wondering how to tell which windows are the most energy-efficient? The British Fenestration Rating Council (BFRC) provides an impartial rainbow rating that is independently verified by experts in building physics. Ratings span from E (poorest) to A++ (best-performing) for a wide range of consumer products, from fridges to vacuum cleaners.

A++ rated double glazed windows will be extremely thermally efficient, helping to keep your home comfortable in all weathers and reducing your energy bills by up to £30 a month. They will have been independently assessed for their ability to negate thermal heat loss and air leakage, so you can be sure that any windows you purchase rated A++ will perform exceptionally well in any weather conditions.

Brackenwood uses only the highest quality materials in our installations. All of our uPVC and aluminium-frame windows come with A++ rated double glazing for ultimate energy efficiency. Our windows also feature the SAC Shootbolt locking system, which adds additional security and takes pressure away from the hinges, ensuring a longer life for your windows. 

Our A++ rated double glazed windows are available with a range of flexible finance options, including Buy Now Pay Later, monthly payments and five years’ interest-free credit.
