How Much Do Bifolding Doors Cost?

Bifolding doors have become a sought-after feature in UK homes, blending indoor and outdoor spaces with style and functionality. These versatile doors, known for their accordion-like folding mechanism, offer expansive views, natural light, and easy access to patios or gardens. In 2025, advancements in design and materials make them an appealing home improvement option. This guide explores the costs, benefits, and factors to consider when installing bifolding doors in the UK.

For many homeowners, bifolding doors are a luxury upgrade that transforms living spaces—until the need for replacement or a new installation arises. Calculating the cost of bifolding doors involves multiple variables, from size and material to installation complexity. Whether you’re dreaming of a seamless garden connection or boosting your home’s resale value, understanding the pricing is key.

Typical Bifolding Door Costs by Size

The cost of bifolding doors largely depends on their width and the number of panels. Below is a table showing typical sizes, panel counts, and cost ranges in the UK for 2025 (including standard installation):

Width (mm)	Number of Panels	Height (mm)	Cost Range (uPVC)	Cost Range (Aluminium)
1800	3	2100	£1,800-£2,500	£2,200-£3,000
2400	4	2100	£2,400-£3,200	£2,800-£3,800
3000	5	2100	£3,000-£4,000	£3,500-£4,800
3600	6	2100	£3,600-£4,800	£4,200-£5,600

In the UK, bifolding doors typically range from £1,800 to £5,600 depending on size and material, plus additional installation costs. These doors are an investment, but their ability to enhance living spaces makes them worthwhile. Wear and tear from weather—rain, wind, or prolonged sun exposure—can eventually necessitate replacement, so it’s wise to plan ahead.

Material Cost Comparison

Before investing in bifolding doors, it’s crucial to research your options. How much do contractors charge, and what materials best suit your home? The answers depend on your budget and aesthetic preferences. Here’s a table comparing popular materials for bifolding doors:

Material	Cost Range (3-panel, 1800mm)	Pros	Cons
uPVC	£1,800-£2,500	Cost-effective, low maintenance	Less sleek, limited colours
Aluminium	£2,200-£3,000	Durable, slim frames, modern look	Higher cost, less insulating
Timber	£2,800-£3,800	Warm aesthetic, natural insulation	Requires upkeep, pricier

How much do bifolding doors really cost? Beyond size and material, factors like glazing, brand, and labour play a role. Costs can escalate with premium features like triple glazing or custom finishes. Homeowners often opt for aluminium for its balance of style and durability, but uPVC remains a budget-friendly choice.

Factors Affecting Bifolding Door Costs

Considering repairs instead? A cracked pane or faulty mechanism might not require a full replacement. Repair costs typically range from £150-£400, depending on damage extent, but extensive issues might push you toward a new set. Here’s what drives bifolding door installation costs:

Factor	Description	Impact on Cost
Size & Panels	Wider doors or more panels increase material use	Adds £600-£800 per extra panel
Glazing	Double vs. triple glazing	Triple glazing adds £200-£500
Material	uPVC, aluminium, or timber	See material table
Labour	£300-£600 per installation	Varies by region
Custom Features	Colours, handles, integrated blinds	£100-£300 extra

Deciding between repair or replacement? Repairs are cheaper short-term, but new bifolding doors offer energy efficiency and modern appeal. If your energy bills are rising or the doors no longer glide smoothly, replacement might be the smarter choice. Consult a professional to weigh your options.

Additional Installation Costs

Choosing bifolding doors is exciting, but the type and material matter. Aluminium suits modern homes, while timber adds warmth to traditional settings. Consider your home’s style and needs—do you want maximum light or better insulation? Here’s a breakdown of extra costs:

Expense	Typical Cost	Notes
Structural Work	£500-£1,500	Lintel installation or wall removal
Removal of Old Doors	£100-£300	Depends on existing setup
Building Regulations	£150-£250	Compliance certification
Finishing (e.g., plastering)	£200-£400	Post-installation touch-ups

Materials like aluminium are low-maintenance and durable, while uPVC offers affordability. Timber requires upkeep but elevates aesthetics. Glazing options—dual or triple pane, with argon or low-e coatings—further tailor performance and cost. A typical 4-panel installation might total £3,000-£5,000 including extras.

Return on Investment (ROI)

Bifolding doors aren’t just about cost—they add value. Here’s how they pay off:

Benefit	Estimated Savings/Value	Timeframe
Energy Savings	£50-£200/year	Ongoing with efficient glazing
Property Value Increase	3-7% of home value	Upon resale
Payback Period	10-20 years	Based on savings and value

Final Thoughts

Bifolding door costs in 2025 range from £1,800 for a small uPVC set to over £5,600 for a large aluminium or timber installation. Factors like size, material, and structural work influence the price, but the blend of practicality and elegance justifies the investment. Compare quotes from reputable UK installers—ideally three—to ensure quality and value. Bifolding doors are more than an upgrade; they’re a lifestyle enhancement.
