Cortizo Bifold Doors Cost UK 2026: Full Price Guide

Cortizo aluminium bifold doors are among the most sought-after glazing systems in the UK premium market. Manufactured in Spain with a strong UK supply chain, they combine slim sightlines, excellent thermal performance and a 25-year powder-coat guarantee. Pricing can be confusing because Cortizo isn't sold directly to homeowners, so you rely on your installer's quote without a published price list.

This guide breaks down what a Cortizo bifold door actually costs fully installed in 2026, what drives the price up or down, and how Cortizo compares to Schuco and Smart at similar specifications.

Typical Cortizo Bifold Door Prices 2026

All prices below are fully installed including supply, survey, manufacture, installation, FENSA certification, 10-year CPA insurance-backed guarantee, and waste removal. Prices reflect current UK market conditions for 2026.

Cortizo Bi-fold Plus Door

The Bi-fold Plus Door is Cortizo's premium bifold system: slim sightlines, thermal break, PAS 24 certified and manufactured to any RAL colour.

• 2-panel, 2.4m opening: £3,500 – £4,500
• 3-panel, 3m opening: £4,200 – £5,800
• 4-panel, 4m opening: £5,500 – £7,500
• 5-panel, 5m opening: £7,000 – £9,500
• 6-panel, 6m opening: £8,500 – £12,000
• 7-panel, 7m opening: £10,500 – £14,500

The range depends on configuration (all panels on one side vs split opening), glass specification, colour, hardware choices, and whether there is a traffic door within the stack.

Cortizo Cor Vision Plus Sliding Doors

Worth mentioning alongside bifolds because many homeowners comparing Cortizo sliding vs bifold end up considering both. Cor Vision Plus Sliding has an ultra-slim 20mm central junction, far slimmer than any bifold's typical 90 to 120mm face, but it operates as a sliding door rather than folding.

• 2-panel, 3m opening: £6,000 – £8,000
• 3-panel, 4m opening: £8,000 – £11,000
• 4-panel, 5m+ opening: £11,000 – £15,000+

See our Cortizo Sliding Doors Review for more detail on the sliding range.

What Drives the Price Up

Eight factors move a Cortizo quote meaningfully:

1. Number of panels. Each additional panel adds roughly £900 – £1,400 to the installed price, depending on size. A 4-panel door is not twice the price of a 2-panel door, because most of the engineering and labour is in the threshold and head track, not the panels themselves.

2. Overall opening width. Wider openings need more robust runners, a heavier-duty head track, and more structural preparation. The jump from 4m to 5m is typically £1,500 – £2,500.

3. Traffic door. A single-panel traffic door within the bifold stack (so you can open one panel without folding the rest) adds £400 – £600 but is a genuine convenience upgrade on doors used daily.

4. Glass specification. Standard low-E argon-filled double glazing is included in the quoted prices. Upgrades: - Triple glazing: +£400 – £800 per door set - Acoustic laminated glass: +£300 – £600 per door set - Self-cleaning outer pane: +£150 – £300 per door set - Tinted or solar control: +£200 – £500

5. Colour choice. Anthracite grey (RAL 7016), jet black (RAL 9005) and white (RAL 9016) are typically quoted at base price. Other RAL colours add £150 – £300. Dual colour (different inside and outside) adds £200 – £400. Marine-grade finishes for coastal installations add £200 – £350.

6. Threshold type. Standard weathered threshold (with an upstand) is included. Flush/low thresholds for level access add £200 – £400 and may require additional waterproofing below the door.

7. Hardware. Standard handles and hinges are included. Designer lever sets from the Cortizo range add £100 – £250.

8. Structural preparation. Replacing a patio door with an existing, correctly-sized opening is the cheapest scenario. Widening the opening, installing a new lintel or RSJ, or rebuilding threshold detail can add £800 – £3,500 to the total project cost. A competent surveyor will identify this before you commit.

• All internal and external trims
• Removal and disposal of the old door

Cortizo vs Schuco vs Smart — Price Comparison

For a 3-panel, 3m opening, fully installed, with standard anthracite grey finish and double glazing:

• Smart Visofold 1000 (mid-premium): £3,800 – £5,200
• Cortizo Bi-fold Plus Door (premium): £4,200 – £5,800
• Schuco AS FD 75 (premium, current UK system): £4,500 – £6,200
• Cortizo Cor Vision Sliding (alternative): £8,000 – £11,000 (but operates as a slider, not a bifold)

Cortizo sits at the lower end of the premium bracket while offering sightlines and thermal performance competitive with Schuco. Smart is a solid mid-premium option for homeowners who want quality aluminium without paying for the top-tier Cortizo/Schuco branding.

Why Cortizo Is Worth the Premium

Three reasons Cortizo commands its price bracket:

1. Powder-coat quality. Cortizo's Qualicoat Class 2 powder coating is engineered to last 40-plus years in UK conditions without fading, chalking or corrosion. Budget aluminium systems often use Class 1 coating that shows visible degradation after 15-20 years.

2. Slim sightlines and engineering. At 110mm reduced central junction on the Bi-fold Plus Door, Cortizo bifolds are among the slimmest on the market without compromising structural rigidity. The difference is immediately visible when you stand next to a budget bifold with 130mm+ stiles.

3. Hardware engineering. Cortizo uses stainless steel bottom-rolling gear rated to 100,000 open-close cycles. Cheaper systems use zinc-alloy rollers that develop play within 5-7 years of daily use. For a door that may open and close 3,000 times a year, this matters.

Lead Times

A realistic production lead time for Cortizo bifolds ordered in the UK is 8-12 weeks from the point of survey approval. Colour changes, non-standard sizes or bespoke hardware can extend this to 14-16 weeks. If your installer quotes a 4-week lead time for a bespoke Cortizo bifold, something is unusual: ask whether the profile is coming from an alternate source or whether the stated brand is actually Cortizo.

Installation Day

A typical 3-panel, 3m Cortizo bifold installation takes one working day for two fitters, assuming the existing opening is correctly sized and weathered. Scenarios that extend installation:

• Opening needs widening — add half to a full day for structural work (often a separate sub-contracted trade)
• New RSJ or lintel installation — half to a full day before the bifold can be fitted
• Non-standard threshold detail — additional half day for waterproofing
• Finishing works — plastering, re-tiling, external pointing are separate trades and typically handled after the door is fitted

Factor these into your project timeline. A simple like-for-like swap is one day; a full rear-wall extension with a 5-panel bifold is a 2-3 week project.

Planning Permission

Replacing an existing door or fitting a bifold in a like-for-like opening is normally permitted development and does not require planning permission. Exceptions:

• Listed buildings (always require listed building consent)
• Conservation areas with Article 4 directions removing permitted development rights
• Widening an aperture beyond permitted development limits
• Altering the frontage of a flat or maisonette (usually requires freeholder consent)

See our Planning Permission for Bifold Doors guide for the full breakdown.

Typical Questions We Get Asked

Are Cortizo bifolds worth it compared to a budget bifold at £3,000?

If you are planning to sell the property within 5-7 years, probably not: a budget bifold will do the job. If you are investing in your home for the next 15-plus years, Cortizo pays for itself in finish longevity, hardware life and lower maintenance. The premium is typically 20-35% over a budget system at like-for-like configuration.

How long do Cortizo bifold doors last?

With proper installation and routine maintenance (light lubrication of the running gear annually), Cortizo bifolds last 40-plus years. The powder-coat finish carries a 25-year Cortizo guarantee. The running gear is rated to 100,000 cycles, roughly 30 years of daily use.

Can I get a quote for a Cortizo bifold without having a survey first?

A ballpark quote based on photos and measurements you provide is possible, but the final price can only be confirmed after a site survey because the threshold detail, structural preparation and waterproofing are all survey-dependent variables. We provide written itemised quotes after every survey with no commitment to proceed.

Frequently Asked Questions

What is the typical lead time on a Cortizo bifold order?

Cortizo manufacture-to-order lead times are 8-12 weeks from order confirmation, plus 1-2 weeks for installation scheduling. The factory is in Padron, Spain and ships directly to UK fabrication partners. Lead times can extend to 14-16 weeks in spring (peak installation season, March-June) and shorten to 6-8 weeks in autumn (October-December). Always confirm a target install date at the survey stage and build a 2-3 week buffer into critical-path renovation programmes.

How does the Bi-fold Plus Door differ from the standard Bi-Fold?

The Plus is the slim-premium tier. Standard Bi-Fold uses a 175 mm meeting-point sightline; Bi-fold Plus reduces that to 110 mm via a redesigned central junction. The visual difference is meaningful on a 3+ panel set where the central panels were where the eye lands. Plus also supports larger individual panels (up to 1.2 m × 3 m) and a slightly tighter Uw figure with the same glass spec. Price premium is typically 15-25% over standard Bi-Fold at the same opening size.

Can Cortizo bifolds be installed with a flush threshold?

Yes — Cortizo offers a Part M flush threshold option on both Bi-Fold and Bi-fold Plus Door. The threshold sits level with the internal floor, eliminating the trip step and meeting Building Regulations Part M for accessibility. Weather performance is one notch lower than a standard weather threshold (rated for moderate exposure, not coastal), so survey location matters — exposed elevations near coast or open countryside default to the weather threshold for warranty cover.

What colour options come at no extra cost vs upgrade prices?

Standard RAL anthracite (RAL 7016) is the volume colour and ships at the base price. The full RAL Classic range is available at a typical 8-12% premium. Bespoke RAL, dual-colour (different inside and outside), structured or matt finishes typically add 12-20% on top of the standard premium. Pearlescent, metallic and specialist coastal-grade finishes are quoted on request and can add 25-40%.

Do Cortizo bifolds qualify for a 0% finance arrangement?

Vitrum Solutions does not offer in-house finance, but many homeowners fund Cortizo installations via a home-improvement secured loan or a re-mortgage drawdown. The installation value (£15,000-£45,000+ for a typical Cortizo bifold project) sits within the range where a mainstream lender treats the spend as a property improvement rather than discretionary spending, which usually means better rates than unsecured personal loans. Speak to a broker before committing — the rate differential can be 3-5% over the loan term.
