Transforming your home with bifold doors is a popular way to bring in natural light, open up space, and enhance the overall aesthetic.
To make informed decisions, it’s essential to understand the full pricing landscape before buying your bifold doors, including materials and sizes to installation and glazing options.
Comparing Bifold Door Costs in the UK
Bifold doors come in a wide range of prices influenced by several key factors such as material type, door size, the number of panels, glazing specifications, and whether you choose supply-only or professional installation.
For many homeowners, deciding between DIY and professional fitting impacts the total cost and warranty coverage.
To give a clear overview, here is the typical price difference between supply-only and fully installed bifold doors for commonly requested sizes:
| Size (Panels) | Aluminium Supply Only | Aluminium Installed | uPVC Supply Only | uPVC Installed |
|---|---|---|---|---|
| 3m (3) | £1,900–£2,800 | £2,500–£4,000 | £1,200–£1,850 | £1,500–£2,500 |
| 4m (4) | £2,850–£3,700 | £3,500–£5,400 | £1,800–£2,900 | £2,400–£4,000 |
| 5m (5) | £3,700–£4,800 | £4,785–£6,200 | £2,600–£3,600 | £3,515–£4,495 |
This comparison shows why aluminium remains the most popular choice for its durability and excellent value, while uPVC offers a more affordable entry point for smaller installations or internal use.
How Door Size and Panel Numbers Affect Prices
Once material is selected, bifold door sizes and panel count further determine costs. The larger the door and the more panels it has, the higher the price due to increased materials and installation complexity. To help visualise this, consider the cost variation in aluminium and uPVC bifold doors based on panel numbers:
| Panels | Width | Aluminium Installed | uPVC Installed | Ideal For |
|---|---|---|---|---|
| 2 | 1.8m | £1,900–£2,400 | £1,200–£1,650 | Compact access doors |
| 3 | 3m | £2,500–£4,000 | £1,500–£2,500 | Standard garden patios |
| 5 | 5m | £4,785–£6,200 | £3,515–£4,495 | Large openings, rooms |
Choosing the correct number of panels is about balancing your opening’s size, desired aesthetics, and your budget. Larger configurations generally require more fitters and longer installation time, especially if structural modifications are involved.
The Role of Glazing: Balancing Cost and Comfort
Glazing options heavily influence both the initial price and the energy efficiency of your bifold doors. Here’s a cost and performance comparison for a 3-metre bifold door:
| Glazing | Aluminium Price | uPVC Price | U-Value | Energy Efficiency |
|---|---|---|---|---|
| Single | £1,800–£2,500 | £1,200–£1,600 | 2.5–3.0 W/m²K | Basic, minimal insulation |
| Double | £2,000–£3,700 | £1,400–£2,000 | 1.2–1.6 W/m²K | Good balance of cost and insulation |
| Triple | £2,800–£4,500 | £1,900–£2,800 | 0.7–1.0 W/m²K | Superior insulation, higher cost |
While single glazing is rarely chosen due to poor thermal performance, double glazing remains the industry standard for most UK homeowners seeking good energy savings. Triple glazing commands a premium but provides excellent temperature control and noise reduction, making it ideal for extreme climates or eco-conscious buyers.
Material Cost Comparison: Finding the Best Value for Your Home
Each bifold door material offers unique advantages and price points. Choosing the best bifold doors for your budget is key, so here’s a direct comparison covering installed cost, upkeep, lifespan, insulation, and looks:
| Material | Installed Cost | Maintenance | Lifespan | Thermal Rating | Style and Appeal |
|---|---|---|---|---|---|
| Aluminium | £2,500–£7,100+ | Low | 20–40 years | Excellent | Sleek, modern |
| uPVC | £1,500–£5,899+ | Very low | 10–20 years | Good | Functional, basic |
| Timber | £3,000–£7,100+ | High | 15–30 years | Good to excellent | Warm, traditional |
| Composite | £3,500–£7,900+ | Low | 25–40 years | Excellent | Customisable, premium |
Aluminium doors are preferred for longevity and contemporary style, while timber suits period properties needing character. Composite doors blend durability with insulating power and bespoke aesthetics, and uPVC remains the cheapest and easiest to maintain, ideal for tighter budgets or internal usage.
Long-Term Considerations: Maintenance and Energy Savings
Beyond upfront costs, it is important to factor in maintenance and energy savings when choosing bifold doors. Aluminium and composite doors require minimal upkeep, whereas timber needs regular treatment to maintain appearance and durability. Good glazing and frame insulation can reduce heating bills significantly over time, making high-quality bifolds a smart investment for comfort and efficiency.
