uPVC French Door Cost: 2026 Pricing Guide

uPVC French door cost typically runs from £500 to £1,200 supply only, or £900 to £2,000 fully fitted, for a standard size set. A standard two-panel set costs less than a wide opening with side panels or a top light. This guide breaks down what drives the price up or down, using real market factors, not a single flat number. It covers Buckinghamshire and Oxfordshire specifically, not the whole UK.

If you want a French door quote you can actually trust, you are asking the right question. Most first-time buyers get a number back and have no way to check if it is fair. This guide gives you that check.

How Much Do uPVC French Doors Cost?

uPVC French door cost is driven by size, number of panels, glazing type, and colour. A basic white standard size set sits at the lower end. Add side panels, a top light, or a colour finish, and the price climbs.

Average Cost at a Glance

A standard uPVC French door set generally costs £500 to £1,200 for supply only. A fully fitted installation typically runs £900 to £2,000, depending on the dimensions, glass spec, and whether you add side panels or a custom colour.

Supply-Only vs Supply-and-Fit Pricing

Supply-only pricing, £500 to £1,200 for a standard set, covers only the manufactured door. It does not include fitting, removal of your old door, or making good. Supply and fit, £900 to £2,000, adds labour, removal, and disposal. Always confirm which basis a quote uses before comparing two suppliers.

What Affects the Cost of a Set of French Doors?

Door Size and Dimensions

Larger openings need more frame and glass, which raises both material and manufacturing cost. This is usually the single biggest driver of total cost, above colour, glazing, or extras. 

Number of Doors and Panels

A standard two-panel set costs less than a configuration with extra fixed panels either side. More panels means more hardware and more manufacturing time.

Frame Colour and Finish

White is the base price. A woodgrain foil or a solid colour finish adds a percentage on top, the same pattern seen across uPVC windows.

Glazing Type (Double vs Triple Glazed)

Triple glazing adds a further cost on top of double glazing. It is worth it mainly on exposed or north-facing openings, not as a blanket upgrade.

Additional Features (Side Panels, Top Lights, Mid Rails, Georgian Bars)

Side panels widen the overall opening and add glass and frame. A top light adds height. Georgian bars add a period look but also add manufacturing detail. Each of these is a genuine cost driver, not just a style choice.

Location and Regional Labour Rates

Labour rates in the South East, including Buckinghamshire and Oxfordshire, generally sit above the wider UK average. This is a real factor, not a generic caveat.

uPVC French Door Cost by Size

Door size is the clearest lever on total price. Within the standard £500 to £1,200 supply-only, £900 to £2,000 fitted range, a basic two-panel set with no extras sits toward the bottom. Side panels and a top light push toward the top.

uPVC French Door Cost by Style and Configuration

Standard uPVC French Doors

A standard set is two equal opening leaves, no side panels, no top light, typically £500 to £1,200 supply only or £900 to £2,000 fitted. This is the baseline every other configuration is priced against.

French Doors with Side Panels

Side panels sit on either side of the main doors and do not open. They add width and light without adding an opening mechanism, which keeps the cost increase more moderate than a third opening leaf would.

Half-Glazed French Doors

A half-glazed design uses a solid lower panel, often with a mid rail, rather than glass down to the floor. This can suit a kitchen or utility room where full glazing is not the priority.

French Doors with Top Lights

A top light adds a fixed glazed panel above the main doors, useful where the opening is taller than a standard door height. It adds cost in proportion to the extra glass and frame involved.

How Much Does It Cost to Fit French Doors in the UK?

The average cost to fit external French doors in the UK is around £2,000 for a standard like-for-like replacement, with a typical overall range of £1,200 to £3,500 including supply and professional installation.

Average Labour Costs

Labour cost depends on whether you are replacing an existing opening or creating a new one, and on access to the property. Ask for labour to be itemised separately from the door supply cost, so you can compare it directly against other quotes.

Labour Cost by Number of Doors

Fitting one set of French doors is usually priced as a single job, not per panel. If your project includes more than one opening, ask whether a day rate applies across the whole job.

Timescales: How Long Does Installation Take?

A straightforward like-for-like replacement is often a one-day job. A new opening, involving structural work, takes longer and depends on weather and access.

New Opening vs Replacing an Existing Opening

Replacing doors in an existing opening is usually the simpler, faster job. Creating a brand new opening means structural work, possibly a lintel, and Building Regulations sign-off, which adds real time and cost.

How Much Do People Charge to Install French Doors?

Labour cost to install French doors in an existing opening typically ranges from £300 to £650. The total cost including the doors themselves usually falls between £900 and £4,500, depending on size and specification.

Typical Day Rates for Installers

Day rates vary by region and by installer experience. In Buckinghamshire and Oxfordshire specifically, expect rates toward the higher end of the national range, reflecting local labour costs.

What’s Included in a Fitter’s Quote

A genuine fitted quote should include removal of your old door, fitting, sealing, and basic making good. If a quote looks unusually low, check what has been left out before assuming it is the better deal.

Getting Multiple Quotes

Comparing three quotes only works if you are comparing the same scope. Match supply only against supply only, and fitted against fitted, before deciding which number is actually competitive.

uPVC vs Other French Door Materials: Cost Comparison

uPVC vs Timber

uPVC is the more affordable, lower maintenance option. Timber has a traditional look but needs regular painting or staining, and it costs more both upfront and over time.

uPVC vs Aluminium

Aluminium gives slimmer frames and a more contemporary look, at a higher price than uPVC. Our aluminium doors range covers that option in full.

Larger or non-residential openings are better served by aluminium commercial doors instead.

uPVC vs Composite

Composite doors combine a durable outer skin with a solid core, generally priced above standard uPVC. Full details are on our composite doors page.

uPVC vs Solid Oak Laminate

Solid oak laminate gives a genuine timber look with better scratch resistance than raw timber. It costs more than uPVC, though. It can also shift shape slightly over time in changing weather.

French Doors vs Other Door Types: Which Costs Less?

French Doors vs Sliding Patio Doors

Sliding doors need no clearance space to open, and they generally give the smallest unobstructed opening of the main door types. French doors open like traditional doors and usually cost less than an equivalent bifold configuration.

French Doors vs Bifold Doors

Bifold doors give the widest possible opening, but more panels and hardware means a higher cost than French doors for a comparable width. If your opening is under 3 metres wide, ask specifically whether French doors give you enough opening width before paying the bifold premium.

Hidden and Additional Costs to Budget For

Removal and Disposal of Old Doors/Windows

Removal and disposal of your old door is often included in a fitted price, but not always. Confirm this explicitly rather than assuming it is covered.

Structural Alterations and New Openings

A new opening may need a lintel and other structural support. This is a genuine additional cost beyond the door itself. It is the main reason a new opening costs more than a like-for-like swap.

Security Upgrades and Locking Systems

Multi-point locking is standard on most French doors today. Upgraded security hardware, where specified, adds a smaller but real cost on top.

Permits and Building Regulations Compliance

Standard door replacement is usually covered by FENSA self-certification. A new opening may need separate Building Regulations sign-off. Confirm which applies to your project before work starts.

Do You Need Planning Permission for French Doors?

Most French door replacements fall under permitted development and do not need separate planning permission. If your property is listed or in a conservation area, check with your local planning department before ordering. Listed Building Consent can apply instead of standard FENSA-covered work, and this varies by property.

How to Reduce the Cost of uPVC French Doors

Choose Standard Sizes

Standard sizes avoid the extra manufacturing time a bespoke opening needs. This is usually the simplest way to reduce cost without reducing quality.

Compare Multiple Quotes

Comparing quotes only helps if you compare the same scope, as covered above. A lower number on a narrower scope is not actually a better deal.

Time Your Purchase

Installer availability often eases slightly outside peak spring and summer booking periods. This is not guaranteed every year, but it is a real pattern worth asking about.

Choose uPVC Over Premium Materials

If budget is the main driver, uPVC gives you the lowest starting cost of the main materials. You do not give up multi-point locking or double glazing performance either.

Checklist: What to Look for in a French Door Installer

• FENSA or CERTASS registration number, checked directly, not just claimed
• A clear statement of whether fitting is in-house or subcontracted
• An itemised quote separating supply, labour, and removal
• A stated guarantee period, in writing
• Trade body membership, where relevant to the material chosen

A Real Buckinghamshire and Oxfordshire Example

Based on Bifold-Doors.com’s experience fitting doors across Buckinghamshire and Oxfordshire, French door enquiries near Aylesbury and Banbury often come from homeowners replacing an existing rear door. It is usually a straightforward like-for-like swap. A homeowner in that position, on a 1930s semi, would typically expect a short survey lead time and a one-day installation, weather permitting.

Compare that with a period property near Thame, where a new opening is being created as part of an extension. Here, structural work, a longer lead time, and possibly listed building or conservation area checks all come into play. That is the part worth raising at survey stage, not after you have already committed.

Turning This Into Your Price 

uPVC French door cost comes down to a few honest variables: size, glazing, colour, and whether you need a new opening or a straightforward swap. A standard set sits at £500 to £1,200 supply only, £900 to £2,000 fitted. Custom sizes, side panels, and structural work all move that figure up.

The most useful thing you can do with this guide is use it as a checklist against your own quotes. If a number looks unusually low, check what has been left out. If it looks high, ask which specific factors are driving it.

If you are still weighing up material before committing to uPVC specifically, the composite comparison above is worth another read.
