Bay Windows

The Window That Changes Everything

A bay window is more than a window, it's an architectural statement. Projecting outward from the wall, a bay window creates a nook of additional floor space, a sense of openness, and a volume of natural light that a flat window simply cannot match.

Available in square, angled (30/45 degree), and bow configurations, our bay windows are fully made to measure and installed by our own experienced team with full structural support included.

  • Square bay, angled bay, and bow bay configurations
  • PVC or aluminium frames, both A++ energy rated
  • Opening casements, fixed panels, or combination
  • Internal bay boards, cushion seats, and shelving available
  • Full structural support and weatherproofing included
  • Wide colour range including dual-colour options

Why Bay Windows

More Than a Window,
A Room Transformer

🏠

Added Floor Space

A bay window physically extends the footprint of your room, creating a cosy reading nook, a desk area, or simply more breathing space in your living room.

☀️

Flood of Natural Light

Three-sided glass means light enters from three directions, illuminating your room from morning to evening far more effectively than a flat window.

🌅

Panoramic Views

The angled side panels open up your sightlines to the garden or street, giving your room a sense of connection to the outside world.

💰

Adds Property Value

Bay windows are consistently cited as a feature that adds significant value and kerb appeal. One of the best investments you can make in your home.

🌡️

A++ Energy Performance

Despite the larger glass area, our bay windows maintain A++ energy ratings with warm-edge glazing and thermally-broken frames throughout.

🔒

Full Security

Every opening casement in the bay is fitted with multi-point locking. Fixed panels use toughened or laminated glass as standard.

Replaced our old single-glazed bay with a new PVC bay from WOW. The difference in warmth and light is extraordinary. The team were meticulous.

WOW installed a large square bay in our front room. The structural work was clean, fast, and the result is magnificent. Neighbours are constantly complimenting it.

Bay Window FAQs

Questions About
Bay Windows

Call Us Now →
Do I need planning permission for a bay window?

In most cases, replacing an existing bay window does not require planning permission. Installing a new bay window may require permission depending on location and size. We will advise you fully during your free survey.

What is the difference between a square bay and a bow bay?

A square bay has two 90 degree corners, a traditional look common in Victorian and Edwardian homes. A bow bay has multiple gentle curves, creating a softer, more flowing appearance. Angled bays sit between these two styles.

Can you add a window seat or bay board?

Yes. We can include internal bay boards, painted MDF shelving, and cushion seat installations as part of the project. Ask at your survey and we'll include these in your quote.

How long does a bay window installation take?

A bay window replacement typically takes one to two days. New bay installations involving structural work may take slightly longer. We always ensure your home is secure and weathertight at the end of every working day.
