Aluminium bifold door prices depend on the size, number of panels and final specification. A smaller 1 or 2 pane bifold will usually cost less than a larger 5 or 6 pane set, while upgrades such as dual colour, specialist glazing, low thresholds, premium hardware and additional profiles can affect the final quote.
Our current aluminium bifold door range starts from £514.31, with 1–6 pane configurations available to configure online.

Choosing the right bifold configuration depends on the opening width, the preferred panel split and how the doors need to stack. For trade quoting, the panel count is often one of the first decisions to make because it affects price, usability and appearance.

Aluminium bifold doors are a popular choice for extensions, renovations and modern home improvements because they combine slim frames, strong construction and flexible opening options.
Compared with bulkier materials, aluminium allows for slimmer sightlines and larger areas of glass. This gives the finished installation a clean, modern appearance while helping bring more natural light into the property.
Key benefits include:
For trade buyers, aluminium bifold doors are easy to sell because they combine the look customers want with the strength and flexibility installers need.
Project delays can affect fitting schedules, customer satisfaction and cash flow. That is why 6 Day Doors is built around fast trade supply, practical quoting and clear communication.
For standard specifications and popular colour options, we aim to keep lead times quick and predictable. If a project needs a special colour, dual colour finish, unusual size or specific glazing requirement, we will confirm the expected lead time at quote stage.

Our Ezifold aluminium bifold door system is designed for real-world trade installations where appearance, performance and ease of specification all matter.
The system gives installers a practical aluminium bifold option for residential projects, extensions, kitchen-diners, garden rooms and replacement patio door openings. With options for pane count, colour, glazing, threshold, cills and hardware, it can be tailored around the opening and the customer’s brief.
For trade customers, the benefit is simplicity. You can quote the door, confirm the specification and order the components needed for installation from one supplier.
Threshold choice can make a big difference to the finished installation. Some projects need a practical standard threshold for everyday weather performance, while others may need a low or flush-style threshold for improved access or a cleaner transition between inside and outside.
Common options include:
For trade orders, send the opening detail and we’ll advise the most suitable threshold and cill combination.
Aluminium bifold doors can be finished to suit a wide range of residential projects, from modern extensions to more traditional homes.
Standard RAL colours are often the best choice when speed and value matter. Popular finishes such as Anthracite Grey, Black and White work well for many projects and can help keep the ordering process straightforward.
Dual colour options are also available where the client wants one colour outside and another colour inside. This is useful when the external finish needs to match existing frames, brickwork or planning requirements, while the internal colour needs to suit the interior design.
Trade quoting tip: confirm colour requirements early, especially if the project needs dual colour or a non-standard finish.
Every bifold project is different, so the final specification should reflect the opening, building use and customer expectations.
You can configure:
For fast pricing, send the basic details first. For the most accurate quote, build the full specification online so the final price reflects the actual door required.
Aluminium bifold doors need to look good, operate smoothly and perform properly once installed. Our bifold systems are designed to support modern expectations for security, insulation and weather protection when correctly specified and fitted.
For projects with a specific U-value, glazing requirement or Building Control requirement, send the details to our team before ordering. We’ll help you choose the most suitable specification for the project.
This is especially important for extensions, renovations and new-build work where compliance details need to be confirmed before installation.
For larger openings and premium trade projects, aluminium bifold doors are usually preferred over uPVC. Aluminium frames are stronger, allowing for slimmer sightlines, larger glass panels and better long-term stability.
uPVC can be more budget-friendly, but aluminium offers greater durability, a more modern finish and stronger appeal for high-value installations. For installers and builders quoting extensions, renovations and wider openings, aluminium is often the better long-term option.
