Additional Costs to Consider

• Double Glazing: Most French windows and doors come with double-glazing as standard. If you opt for triple glazing, expect an additional cost of £150 to £250 per window or door.
• Installation: Installation costs for French windows and doors in the UK generally range from £250 to £600, depending on the complexity of the job and the region.
• Removal of Old Windows/Doors: If you’re replacing old units, there will be an additional fee of £100 to £300 for removal and disposal.

Factors Affecting the Cost of French Windows and Doors

Several factors influence the price of French windows and doors, including:

Material

The material used for French windows and doors plays a significant role in determining their cost. The three most common materials are uPVC, wood, and aluminium, each offering different benefits and price points.

uPVC

Often the most affordable option. It offers excellent durability and weather resistance. It is a popular choice due to its low maintenance requirements and energy efficiency. However, it may not provide the same aesthetic appeal or luxury feel as wood or aluminium. Expect to pay less for uPVC French windows and uPVC French doors compared to the other materials.

Wood 

Wooden French windows and wooden French doors are prized for their classic look and natural charm. Timber is a great insulator and can be more environmentally friendly if sourced sustainably. 

However, wooden windows and doors require regular maintenance, such as painting and sealing, to prevent deterioration over time. The premium look and feel come at a higher cost, with wooden frames generally priced higher than uPVC but lower than aluminium.

Aluminium

Aluminium French windows and aluminium French doors are ideal for those who want a sleek, modern aesthetic. Aluminium frames are highly durable and lightweight, offering a minimalist, contemporary design. 

Though more expensive than uPVC or wood, aluminium is known for its strength and longevity. It is also a popular choice for large-scale installations due to its ability to support larger panes of glass. If you’re looking for a high-end, stylish option, aluminium is the way to go.

Glass Type

The type of glass you choose for your French windows or doors can significantly affect the overall cost. There are 2 common glass types used in French windows and doors: double-glazed and triple-glazed.

Double-Glazed

Double-glazed French windows and doors are an ideal balance between cost, energy efficiency, and comfort. As energy prices continue to rise, investing in double-glazed units is often a wise decision. The price of double-glazed French windows typically sits in the mid-range and is highly recommended for most homeowners.

Triple-Glazed

Triple-glazed French doors and windows come at a premium and are typically chosen for luxury homes or buildings where top-notch thermal insulation is essential. 

Expect to pay more for triple-glazing compared to double-glazing, but the added cost can be offset by long-term energy savings.

Size and Dimensions

The size of the French windows or doors, as well as the number of panels, will significantly impact the cost. Larger units naturally require more materials, and this drives up the price. Additionally, the number of panels involved in the design also plays a role in pricing.

Small Units

A small French window or French door (e.g., 1.2m x 1.5m) typically costs less due to the smaller materials required. These are ideal for compact spaces like smaller living rooms, kitchens, or hallways.

Medium and Large Units

As the size increases, so does the cost. Larger French windows (e.g., 2.0m x 2.4m) allow for more glass and offer a more open, spacious feel. Additionally, more materials are used in the frame, and the installation may become more complex. 

The price can increase by several hundred pounds for larger units.

Number of Panels

Standard French windows and doors typically have two panels, but many homeowners opt for more, especially in larger installations or as part of a larger patio or balcony. The more panels you add, the higher the cost, as more materials and labour are required.

Customisation

Custom-made designs or bespoke finishes often come at a premium compared to standard models. If you require French windows or French doors in unique sizes, shapes, or finishes, expect to pay more for the additional design work and craftsmanship involved.

Unique Sizes

If your property has non-standard openings or you require windows or doors that fit a specific architectural design, custom sizing will increase the price. This is especially true for heritage properties where traditional styles or specific measurements must be adhered to.

Bespoke Finishes

Some homeowners opt for special finishes such as painted wooden frames, decorative glazing, or custom hardware (e.g., handles and locks). These bespoke options, while aesthetically pleasing, will naturally increase the cost. 

If you want a specific colour or texture, or if you’re opting for a luxurious finish, the price can be substantially higher.

Energy-Efficient and Soundproofing Option

If you’re willing to pay a bit more for energy efficiency or soundproofing, you might consider additional features like low-emissivity (Low-E) coatings or acoustic glass. These features, while providing long-term benefits, often add to the initial cost of installation.

FAQs

Are French windows more expensive?

Yes, French windows tend to be more expensive than standard windows. The cost of French windows is influenced by factors such as material (uPVC, wood, aluminium), glass type (single, double, or triple glazing), and size. 

French windows usually have larger glass panes, more intricate frame designs, and additional hardware compared to regular windows, which can increase the overall cost. Additionally, custom or bespoke designs will drive up the price further.

If you’re considering various types of windows for your home, it’s essential to understand how different styles and materials can impact your budget. Our new window costs guide breaks down the pricing for a wide range of window types, from standard replacements to more specialised options

What is the difference between a French window and a normal window?

The main difference between a French window and a normal window lies in their design and functionality. French windows are typically hinged at the side and open outward, similar to French doors but in a vertical format. 

They consist of two panels that open fully, allowing for an unobstructed view and better airflow. In contrast, a normal window (such as a casement or sash window) is usually a single panel or two smaller panes that open in a different manner, either sliding or tilting inwards.

Do you need permission to install French doors?

In most cases, you do not need specific planning permission to install French doors if you are replacing an existing door or window. However, if you live in a listed building, a conservation area, or are making major structural changes (such as enlarging the opening), you may need permission from your local council. 

It’s always advisable to check with your local planning authority before proceeding with any installation.

Can I replace a window with French doors?

Yes, you can replace a window with French doors if the structure allows for it. This is a popular option for homeowners who want to create a more open and accessible space, such as opening up to a garden or patio. 

However, replacing a window with French doors may involve altering the opening size, which could require additional structural work. You may also need to check if planning permission is necessary, especially if you are enlarging the opening.

How much does it cost to convert a window into French doors?

The cost of converting a window into French doors depends on several factors, including the size of the window, the materials used, and whether any structural modifications are required. 

On average, the cost for a conversion can range from £1,000 to £3,000 or more. This includes the cost of the French doors, installation, and any necessary structural adjustments. The complexity of the job and any permissions required can also influence the final price.

Can a bedroom have French doors?

Yes, a bedroom can have French doors, but there are a few considerations. French doors are a great way to bring in natural light and enhance the aesthetic of a room. However, depending on the layout and privacy needs, French doors may not always be the most suitable choice for a bedroom, particularly if the doors open directly onto a shared space or external area. If privacy is a concern, you can opt for frosted or opaque glass panels. 

Always consider the practical aspects, such as security and the room’s function, before installing French doors in a bedroom.
