Energy Efficiency

Here at Windows 4 Less we know that choosing the right replacement windows and doors is not only about the great new looks and curb appeal.


Our fantastic range of new energy-efficient windows and doors will not only look good, but will also help to keep you warm, reduce your heating bills and with it your carbon footprint.

With all our ‘Rehau Total70’ system based windows achieving an A+ energy rating and our replacement doors being just as carefully chosen to deliver outstanding performance, reduce heat loss and keep out the cold, we are confident that your home will be as warm as possible and be saving you money at the same time.

Double glazing endorsed by the industry energy specialists BFRC

The energy ratings that we quote within this website and our business as a whole are designed to give home owners an indication to the energy performance of a given window or door.


This energy rating scheme has been developed and is endorsed by industry energy specialists, the BFRC; the UK’s premier authority for independently verified ratings of energy efficient windows and energy efficient doors.


In order to carry the BFRC  seal of approval, a window must ensure a high energy performance and every component of the window is checked to ensure it meets their strict criteria. That's why we choose to work with manufactures whose products; such as the ‘Rehau Total70’ system, are designed to achieve an A+ energy rating (the higher the rating, the better the energy performance) when installed with the appropriate glazing unit.


All our A+ energy rated windows are proudly BFRC accredited and are endorsed to display the ‘Energy Saving Recommended’ logo (shown left), so that you can be assured of their superior efficiency and be confident your home will be as warm as possible, as well as saving you money at the same time.
