What's the Average Cost of Aluminium Bifold Doors?
For a quality aluminium bifold door, expect to pay in the region of £1,500–£3,000 per leaf including installation. A three-panel set enough for a standard kitchen extension typically falls between £4,500 and £8,000 fitted. A wide five or six-panel set spanning a full wall can reach £10,000–£15,000 or more.
Those figures might feel broad, but that's because the gap between a mass-market aluminium bifold and a precision-engineered system like Origin's is significant in hardware quality, thermal performance, finish longevity, and how the doors feel to open and close twenty years from now.
What Affects the Price of Bifold Doors?
Width and Number of Panels
The single biggest cost driver is size. More panels mean more aluminium, more hardware, and more glass. Wider openings may also require a steel beam or substantial lintel above the opening, which is a separate structural cost. A two-panel set is the cheapest entry point; larger configurations simply scale from there.
Frame Material
uPVC bifold are cheaper upfront but carry a shorter lifespan, less design flexibility, and a bulkier profile. Aluminium is stronger, slimmer, available in hundreds of RAL colours, and holds its finish for decades. For a quality installation, aluminium is almost always the right material choice.
Glazing Specification
Standard double glazing keeps costs lower; thermally broken triple glazing improves heat retention significantly important for north-facing doors or where building regulations require tighter thermal targets. Low-e coatings, acoustic glass, and laminated safety glass all affect the price and are worth discussing with your supplier.
Hardware and Threshold
The quality of running gear matters more than most buyers realise. Cheap bifold develop stiff action and misalignment within a few years. Premium hardware like that used in Origin systems is precision-engineered to run smoothly over thousands of cycles. The threshold type (low, flush, or ultra-low) also affects cost and installation complexity.
Colour and Finish
Standard RAL colours (white, anthracite, grey, black) are included in base prices. Dual-colour finishes different colours inside and out typically add 10–15% to the frame cost and are popular for those wanting dark grey outside but white internally.
Installation
Labour costs in the UK range from £500 to £1,500 depending on the complexity of the opening, lintel work required, and how the doors are being integrated into an existing structure versus a new extension.
Is There a Cost Difference Between Brands?
Yes, and it matters. Budget aluminium doors might look similar in a brochure, but the difference shows in the tightness of the seal, the smoothness of operation, the quality of the coating, and how the manufacturer supports you if something goes wrong.
Origin is the UK's leading premium aluminium door manufacturer and offers a 20-year guarantee on their products something cheap imports simply cannot match. At SmartaView, we supply Origin exclusively because we believe the quality of what goes into a home is worth paying for.
Do Bifold Doors Add Value to a Property?
Generally, yes. Research consistently shows bifold doors are one of the features buyers specifically look for in family homes, particularly when buying properties with gardens. A well-specified set of aluminium bifold can add meaningful value to a property and more importantly, they transform how you use your home every single day.
What's the Bottom Line?
Set a realistic budget before you approach suppliers. For premium aluminium bifold doors from Origin, budget a minimum of £5,000 for a modest three-panel set installed. For a wider, architecturally significant opening, £8,000–£12,000 is realistic and sensible.
What you shouldn't do is cut corners on door quality to save money, then spend the savings on the kitchen worktop. Bifold doors are structural, weatherproof, security-critical elements of your home. Buy quality once.
