Bay Windows: Benefits, Styles & Prices

A bay window is any type of window that projects out from the main walls of a property to form a bay within the room.

By having bay windows installed, you can benefit from better views of the outside, increased light into the home and more ventilation during the summer months.

What are bay windows?

Rather than being flat across the wall, bay windows project outwards to create a unique selling point from the outside while making an internal room more spacious.

Typically, bay windows have 3-5 panels, with 5 panels offering more panoramic views and increased ventilation as there are more panels to open up.

Bay window styles

All bay windows are the same in the sense that they project outwards from a flat wall but there are several styles that each offer a unique look to the outside of a home.

Box windows
Box bay windows are shaped like a box, with flat sides protruding out of the wall that are connected by a flat front.

Bow windows
Bow windows are curved, creating a rounded appearance on the outside of the home. Featuring more windows than a typical bay window, they allow more light into the room. Normally, bay windows have 3 openings, available in angled projections, bow windows, on the other hand, usually have 4 or 5 openings.

Circle bay windows
Circle bay windows are the most rounded style – a smooth semi-circle coming out from the property featuring several window panes all the way around.

Bay window materials

The most common material for bay windows across the UK is uPVC, mainly because it’s the cheapest, but due to its white plastic appearance it isn’t the most charming of materials.

Timber is often the most sought after material for new windows but can be expensive. If you’re after the look of wood, closer to the price of uPVC, it’s possible to get uPVC with woodgrain effect.

Another choice is aluminium, a modern, strong and resilient material that has the best energy efficiency qualities of any window material.

What are the benefits of bay windows?

From the outside bay windows add a traditional charm to a home that can make for a real selling point, while inside they help to make a room more spacious and comfortable. These are some of the benefits that installing bay windows can bring to a home:

• Better all-round views
• Adds a charming and traditional elegance
• Increased ventilation
• Allow more light into the room
• Make the room feel much more spacious
• Could add value to your home
• Often involve low maintenance
• Durable choice of window that can withstand just about any weather condition

As well as the above, the additional space created within the home where the bay window goes outwards can be turned into a bench or storage space.

Are there any downsides to installing bay windows?

The benefits of bay windows definitely outweigh the potential downsides but there are still a few things to consider:

• Installation can be complicated making them more expensive than other window styles
• More light can mean a hotter room during the summer so you might want to consider glass with UV protection

It’s also important to consider insulation as any heat escaping your home will only add to your energy bills.

Bay window insulation

As with any windows around your home, it’s important to consider the insulation so that heat isn’t escaping your property – which, in turn, will mean your central heating system has to work harder, increasing your energy bills.

So, when having bay windows installed, we highly recommend considering the following:

• Double glazing: rather than a single pane of glass, double glazing has 2 which are separated by a gas (commonly argon) acting as an additional layer of insulation.
• Ceiling to floor curtains: bay window curtains are a less subtle form of insulation that has more impact on the decor of the room than other forms of insulation. Whether or not you feel they will compliment the room, curtains are an effective way of keeping the heat in and the cold out.

How much do bay windows cost?

The total price of bay windows comes down to a number of things:

• Material
• Size of the window
• Number of panels (normally 3-5)
• Glazing of the window panes (single, double or triple)
• Floor of the property
• The installer carrying out the installation

You can get an idea of how much you can expect to pay for bay windows of various sizes, before installation, in the table below.

Number of panels	3 panels	4 panels	5 panels
uPVC	£1,000 – £1,300	£1,400 – £1,700	£2,000 – £2,500
uPVC (wood grain effect)	£1,000 – £1,400	£1, 400 – £1,900	£1,750 – £2,500

Bay windows are an expensive type of window, as you can see when comparing the potential costs with other styles. Please note that the prices in the table below aren’t exact figures and will vary based on size, material and glazing.

Type of window	Potential cost per window (not including installation)
Bay window	£1,000 – £1,300
Casement	£150- £575
Sash	£550 – £850
Tilt & turn	£450 – £600

A bay window can really open up a room. It lets more natural light in, makes the room feel bigger, and stands out as a beautiful focal point on your home. While you can certainly hire a pro to install a bay window, you can save a considerable amount of money by installing a bay window yourself, although you’ll still need a contractor to size the opening and order the window. Keep in mind, this is no beginner project. Installing a bay window requires at least 2 additional helpers and a thorough knowledge of power tools, woodworking, and framing. With 3 people and the appropriate tools and materials, expect to spend roughly 6-10 hours installing a bay window.
