How much depends on how many windows you have and how old they are, but as a guide, the average home that contains 15m² of glass could save over £200 a year in energy bills.
Modern windows and doors, like fridges, freezers and washing machines, can now carry energy rating labels to make it easier for you to find the most efficient solution for your home.
Modern windows and doors are now typically glazed from the inside so burglars can’t easily remove the glass. Simple window locks have now been replaced with ultra-secure shoot bolts.
Modern windows have never offered you more options to enhance your home. Sight lines are slim with trims and seals now hidden out of sight. Frames no longer need be white or shiny and smooth, as modern coloured foils are hard to distinguish from stained timber and texture.
