There are many reasons to choose bi-fold doors when embarking on a home improvement project.
Featuring two (or more) panels that are hinged together, bi-fold doors can either open partially or be pulled back entirely for an uninterrupted entryway into your outdoor space. The only difference is that they can also be installed as internal doors which can create a versatile living area. In terms of pricing, bi-fold door prices have generally increased from 2019 to now, mainly due to rising material and manufacturing costs, as well as higher demand for home renovations in recent years.
Bi-fold doors are a great way to add a refreshing contemporary touch to an older property, or complement a modern home with sophisticated style.
But in terms of overall costs, how much are bi-fold doors? What are the main factors that affect the average price?
Why choose bi-fold doors?
In modern homes, many homeowners are seeking new ways to blur the boundaries between inside and outside space, which is where bi-fold doors excel.
You may think that bi-fold doors are only useful in the summer when you can open them up and create a seamless indoor and outdoor space, but they are equally stylish in the winter when they allow plenty of natural sunlight to flood in.
When considering fold doors, the cost difference between internal and external models is significant. Internal bi-fold doors are typically less expensive because they require lighter materials and simpler installation, while external bi-fold doors with aluminium frames are built with more robust different materials for weather resistance, which increases their price. External options also may need additional security and insulation features, contributing to higher costs than internal fold doors.
Bi-fold doors also take up minimal space when they are fully open, meaning that you can enjoy uninterrupted views of the outside.
How much do bi-fold doors cost?
Generally, the average cost of bi-fold doors will begin at around £2000 and can go as high as £8000, but you must also remember to factor in labour costs for your installation.
The exact price of your doors will largely depend on several factors, such as the material you choose and the number of panels.
Which material is best?
Bi-fold door costs largely depend on the material you choose.
If you’re on a budget, the most affordable material is uPVC, which will also offer durability and low maintenance requirements.
However, aluminium is often the most popular choice for bi-folds, and is known for its sleek and sophisticated finish. Although the cost of aluminium is slightly higher than uPVC, the material’s strength means that the frames can hold larger panes of glass. This means you get to enjoy slim sightlines, uninterrupted views and the maximum amount of natural light.
Factors affecting bifold doors cost
When people search for how much are bifold doors they are usually looking for realistic pricing information to plan a project in different locations. The cost of bifold doors varies widely depending on key factors, including aspects of the design, and a complete package often influences the overall pricing.
- Panels
- Frame Material
- Glazing Specification
- Installation complexity
Panels:
The more panels you choose to have, the more your exterior bifold doors will cost.
1. Number of panels : The more panels you choose to have, the more your doors will cost.
Originally, most bi-fold doors had only two panels (hence the word ‘bi-fold’!). However if your doors will have to fit into a large space, more panels might be necessary.
2. The size of panels : The material and number of panels used in your bi-fold doors, the size of the panels used in the doors can also affect the price.
Larger panels typically contain larger areas of glass, which will mean that you can maximise your view and the amount of natural light that comes in. However, larger panels will generally be more costly!
Frame material
uPVC is generally the most affordable; aluminium costs more but offers slimmer profiles and greater strength. The material you choose for your bi-fold doors will influence the overall cost.
uPVC is usually the most cost-effective option, while aluminium tends to be priced higher due to its strength, slimmer sightlines and durability. The finish you select, such as bespoke colours or textured coatings, can also affect the final price.
Glazing specification
Upgrading to triple glazing or specialist coatings adds to the total price. The type of glazing used in your bi-fold doors can impact how much they cost.
Standard double glazing is the most common choice, but upgrading to triple glazing, solar control glass or enhanced thermal coatings will increase the overall price. Higher-performance glass can improve insulation and comfort, which may justify the added investment.
Structural requirements and installation
Larger openings, structural changes or challenging site access can increase labour time. The complexity of the installation can also affect the cost of bi-fold doors.
If the opening needs to be widened, reinforced or fitted with a new lintel, this will add to labour and material costs. Challenging access or adjustments to existing brickwork may also increase the time required to complete the installation.
