How new windows can cut your energy bills this winter

With energy costs still a concern for many households, your windows are one of the most effective places to make a lasting difference. Up to a quarter of a home's heat can be lost through inefficient windows, so an upgrade pays back in comfort and savings.

Modern windows are rated from A++ down to E, much like household appliances. The rating reflects how well the whole window keeps heat in, factoring in the glass, the spacer bars, the gas between the panes and the frame itself.

A-rated and above units use low-emissivity (low-E) glass and argon gas filling to dramatically reduce heat transfer, keeping warmth inside where you want it.

Energy-efficient windows do more than trim your bills. They cut draughts, reduce outside noise, minimise condensation and help maintain a consistent, comfortable temperature throughout your home.

If your current windows are more than 15 years old, or you notice cold spots and misting between the panes, it's well worth getting a free assessment.
