Transform your home with a beautiful bespoke bay window. Available in four different structural and non-structural bay designs in uPVC, wood and aluminium, our bay windows are made-to-measure in a range of colours and finishes.
Choose between a traditional splay bay, square bay, single-end bay or a curved bow window configurations. Our windows are made in Britain and come in double and triple glazing options depending on the bay window frame material.
When you imagine a bay window, it’s likely to be a splay bay that springs to mind. Made up of three or more panes, a splay bay window has a central window and two splayed side windows which usually open from the top.
Single-end Bay
Made up of two panes connected at an angle of up to 90 degrees, a single-end bay window adds more light than a window that sits flush with the wall line. It is a fun and stylish feature ideal for smaller properties.
Bow Window
Bow windows - also known as circular windows and curved bay windows - are comprised of five individual panes in a semi-circle configuration which can be both structural and non-structural. This curved design creates the perfect place to relax and enjoy the panoramic view.
Square Bay
Usually made up of three or more window frames joined in the corners at a 90-degree angle to the wall, a 1930s style square bay or box window shape is ideal to create an internal window seating or storage area.
Our most popular option, uPVC bay windows come in a casement, flush or sash style with a range of customisations. They are a practical and cost-effective investment.
Wooden Bay
Wooden bay windows are handcrafted in the UK and come in casement, flush or sash style with a wide range of finishes and decorative glass options to choose from.
Aluminium Bay
With slim frames and stylish looks, casement aluminium bay windows are a great option for the modern home. They are secure, durable and come in over 200 RAL colours.

Your Questions Answered by us
What are bay windows?
Bay windows are usually made up of three or more window panes, extending outwards in an arc or square to create a feature window. It provides extra internal space, floods a room with light and the curved design makes for impressive panoramic views.
How much is a bay window?
The cost of having a bay window installed varies depending on the material you choose, the size, style, whether it is structural or non-structural other individual requirements for your home. It also depends which supplier you go with, our design team provide you with a unique quote, and how much you pay includes the in-home or remote visit, professional survey and installation.
What is the difference between a bow and a bay window?
While you'd do well to tell a bay and a bow window apart at first glance, there's a simple way to tell the difference. A bay window is usually comprised of three panes with a fixed central pane and an angled window to each side that opens. Whereas a bow window might be made up of four or five panes and tends to be rounded, so it appears like a half-circle from the exterior.
What styles do bay windows come in?
Bay windows come in several styles, including splay bay, single-end bay, a bow window and a square bay. In addition to their shape, bay windows also come in structural and non-structural styles. This means they are either load-bearing or a purely decorative window. We offer bay windows in casement, flush casement, sash and cottage styles.
Do you need planning permission for a bay window?
If you are replacing an existing bay window then it is likely that you will not need planning permission. But this may be different if you are adding a new one to a room or if you live in a conservation area and you have a listed building. Before embarking on any project it is important to consult with your local planning authority or if you go through a supplier like Anglian, we take care of any planning permission requirements for you.
