Wondering about the bi fold doors cost in the UK for 2025? You’re not alone. With their ability to seamlessly merge indoor and outdoor living spaces, bifold doors remain one of the most popular home improvement choices across the country. Whether you’re looking to install bifold patio doors for your garden or internal bifolds for a conservatory, understanding the cost of bifold doors and installation is essential. This guide breaks down the average cost, features, and installation options you can expect in 2025.
What is a Bifold Door?
A bifold door consists of two or more panels hinged together that fold back in sections to open. Unlike traditional swinging doors, bifolds slide along a track, folding neatly to one side, making them ideal for both internal doors like conservatories and external areas such as patios. While many bifold doors feature large glass doors or panels for natural light, materials can vary. Whether you need versatile space-saving internal doors or elegant external patio solutions, high quality bifold doors installation ensures your new doors function smoothly and enhance your home’s style. Bifold doors offer a perfect blend of functionality and elegance.
Key Benefits of Bifold Doors:
Maximize Space: Unlike traditional doors that swing open, bifold doors fold neatly to one side, saving space and allowing for flexible room layouts, especially in smaller or compact areas.
Increase Natural Light: Large glass panels, often spanning entire door sections, allow significantly more sunlight to enter your home compared to conventional doors, brightening interior spaces and creating a seamless indoor-outdoor connection.
Enhance Home Aesthetics: With sleek lines and modern designs, bifold doors add contemporary style and visual appeal to both interior and exterior spaces, boosting overall property value.
Improve Energy Efficiency: High-quality glazing options (such as double or triple glazing) help reduce heat loss and improve insulation, lowering energy costs and increasing comfort.
Enhance Security: Modern bifold doors come with multi-point locking systems and toughened glass options, providing enhanced security for your home.

Glazing Options and Their Impact on Cost and Performance
Choosing the right glazing for your bifold doors is essential not only for price considerations but also for energy efficiency, security, and comfort. Here’s a comparison of common glazing types, their typical additional costs relative to standard double glazing, and their benefits:
| Glazing Type | Typical Cost Increase* | Key Benefits | Best For |
|---|---|---|---|
| Double Glazing | Baseline (standard) | Good thermal insulation and noise reduction | Budget-conscious buyers |
| Triple Glazing | Approximately +20–30% | Superior heat retention and soundproofing | Energy-efficient and quiet homes |
| Laminated Glass | Additional £300–£600 | Enhanced security and improved soundproofing | Homes requiring extra safety |
| Solar Control Glass | Additional £150–£400 | Reduces overheating by blocking solar heat | Warmer climates or sunny areas |
*Costs are approximate and based on comparison to standard double glazing prices.
💡 Tip #2: If your home currently has single glazing—a single glass pane with minimal insulation—you may qualify for UK government grants to upgrade to double glazing, helping you save on energy bills in the long term.
Installation and Labour Costs for Bifold Doors in the UK (2025)

| Medium (4–5 panels) | £2,800 – £4,500 | Standard size for many homes |

- Removal of old doors: Typically adds £100 to £300 to the overall cost.

💡 Tip #3: Always obtain quotes from at least three FENSA-accredited installers—these professionals meet UK building regulations and quality standards, ensuring your installation is safe, compliant, and warranty-backed.

Comparing Bifold Door Materials: Which One Fits Your Needs Best?
The material you choose for your bifold doors plays a crucial role in aesthetics, cost, energy efficiency, and durability. Here’s how the most common options compare in the UK market:
| Material | Avg. Cost Installed | Lifespan (Est.) | Thermal Efficiency | Maintenance | Ideal For |
|---|---|---|---|---|---|
| Aluminium | £1,600–£7,000 | 30–40 years | High (with thermal breaks) | Very Low | Modern homes, premium builds |
| uPVC | £1,000–£5,000 | 15–25 years | Good | Low | Budget projects, rentals |
| Timber | £3,000–£7,500 | 20–30 years | Excellent | High | Heritage or traditional homes |
| Composite | £2,500–£7,000 | 25–35 years | Very High | Medium | All-rounders, eco-conscious builds |
🧱 Aluminium
✅ Modern aesthetic with slim sightlines for maximum glass area.
✅ Strong, lightweight, and ideal for large openings.
❌ Can feel cold to the touch in winter if not thermally broken.
🔐 Best for security-focused installations.
🔧 uPVC
- ✅ Most affordable option with decent insulation.
- ✅ Available in various colours and finishes.
- ❌ Thicker frames reduce natural light; prone to discolouring over time.
- 📦 Best for smaller budgets or rental properties.
🌲 Timber
- ✅ Unmatched classic look with natural insulation.
- ✅ Can be customized with different finishes.
- ❌ Requires ongoing maintenance and is vulnerable to moisture.
- 🏡 Best for period homes and listed properties.
🧪 Composite
- ✅ Blends the best of other materials: strength, insulation, and style.
- ✅ Lower maintenance than timber, better thermal performance than uPVC.
- ❌ Less customizable; premium pricing.
- 🌍 Best for eco-conscious homeowners seeking a balance of form and function.
💡 Final Tip: In colder regions or coastal areas, aluminium and composite doors provide the best long-term resistance to weather exposure. If energy efficiency and sustainability are top priorities, opt for composite or FSC-certified timber options. For a balance of affordability, low maintenance, and performance, durable uPVC door solutions are also a smart choice for many homeowners.
