FAQs

What is a bay window?

A bay window is a window design that projects outward from the main wall of a building, creating a small alcove or “bay” inside the room. It’s typically made up of three window panels set at angles, forming a wider view and allowing more natural light to enter. Bay windows are popular for adding space, enhancing kerb appeal, and creating a bright, open feel in any home.

What is a bow window?

A bow window is a curved window structure made up of four or more window panels set in a smooth arc. Unlike the angular shape of a bay window, bow windows create a gentle, rounded projection that adds elegance and extra space to a room. Their design allows more light to enter from multiple angles, creating a bright, spacious feel and a distinctive architectural feature.

Do you need planning permission for a bay window?

In many cases, you do not need planning permission to install a bay window if it is considered a like-for-like replacement. However, if you are adding a new bay window where one didn’t previously exist, or if the design significantly alters the exterior of your property, planning permission may be required. Always check with your local planning authority before starting work.

How much do bow windows cost?

The cost of a bow window can vary depending on several factors, including the size of the window, the number of panes, the style of glazing, and the chosen frame finish. Additional features such as upgraded energy-efficient glass or bespoke colours can also influence the final price. For an accurate figure, it’s always best to request a tailored quote based on your project’s exact requirements.
