Composite Door Cost: 2026 UK Pricing Guide

Composite door cost ranges from £800–£2,500 fully installed in the UK, with supply-only options starting around £600. Most homeowners pay £1,000–£1,500 for a standard, high-security replacement front door including professional fitting, with installation labour typically adding £350–£600 on top of the door itself.

If you’ve had one quote already, you’ve probably noticed the price didn’t quite match what you expected online. That’s normal; composite door cost varies more than most home-improvement purchases, because “composite door” covers a wide range of core materials, glazing options, and hardware specs.

Based on Bifold-Doors.com’s experience fitting doors across Buckinghamshire and Oxfordshire, from Victorian terraces near Oxford’s Cowley Road to new-build estates on the edge of Bicester, the biggest source of quote confusion is rarely the door slab itself. It’s whether the frame needs replacing, and whether the fitter is in-house or subcontracted.

This guide tells you composite door cost properly: supply-only versus fully fitted, what drives Oxfordshire pricing specifically, and what actually decides your final invoice.

How Much Does a Composite Door Cost?

A composite door costs £600–£1,600 supply-only, or £800–£2,500 fully fitted, with most homeowners paying £1,000–£1,500 for a standard specification. Fully fitted is the more common route, since it includes old-door removal, frame fitting, and weatherproofing in one price.

Supply-Only vs Fully Fitted Prices

The raw door unit alone typically costs £550–£1,400, with installation labour adding £350–£600 depending on frame condition and access. Supply-only shifts the fitting risk onto you; get the frame measurement wrong, and a composite door doesn’t forgive it the way a standard timber door might, since the multi-point locking system needs precise alignment to function properly.

What’s Included in a Fully Fitted Price?

• Removal and disposal of the existing door and frame
• Supply of the door slab, outerframe, and hardware
• Professional installation and weathersealing
• A FENSA certificate confirming Building Regulations compliance

What’s Included in a Supply-Only Price?

• The door slab and outerframe, made to your measurements
• Standard hardware (handle, letterplate, multi-point lock)
• Delivery to your property
• No installation, old-door removal, or FENSA certification

Composite Front Door Cost Explained

Composite front door cost depends heavily on core construction and glazing choice, with total spend typically landing between £1,000 and £3,000 fully installed once specification is factored in. Core material, glazing, and colour are the three biggest price drivers. If you’d like a fixed price rather than a range, you can request a free quote for your exact specification at any point; there’s no obligation attached.

Typical Price Ranges by Specification

Here’s the part most first-time buyers get wrong: assuming glazing is a small add-on. Decorative glass, particularly bespoke or leaded designs, can add several hundred pounds on its own, before colour is even factored in.

Composite Door Price List: Oxfordshire

A fully installed composite door in Oxfordshire typically costs £1,200–£2,750, running slightly above the UK national average because the county sits within the higher-cost South East labour market. Specification and installer type, local independent fitter versus national brand, both move the final figure.

Average Prices for Oxfordshire Homeowners

Entry-level supply pricing in Oxfordshire generally starts around £750–£1,100, with installation labour typically starting from £500 rather than the £350 low end seen in cheaper regions. A homeowner replacing a front door on a new-build estate near Bicester will usually pay toward the lower end of the £1,200–£2,750 range, since the opening and frame are already standard-sized and easy to access.

A Victorian terrace near Oxford city centre, closer to landmarks like Cowley Road or the Iffley Road area, often sits higher; older frames are rarely a perfect standard size, and on-street parking permits can add a day to scheduling if a suspension is needed for the fitting van.

If your project is actually a rear extension rather than a front-door replacement, it’s worth checking our aluminium bifold doors range instead, since the pricing and installation logic differ quite a bit from a single front door.

If your property sits within a conservation area, parts of central Oxford and Woodstock among them, door colour and even glazing pattern can be restricted by local planning guidance, separate from any FENSA-covered installation requirement. Check with your local planning department before ordering a bespoke colour.

Composite Door Installation Cost in Oxon

Composite door installation cost in Oxon typically starts from £500, higher than the £350 UK low end, reflecting South East labour rates. Frame condition is the single biggest driver of installation cost, more than the door specification itself.

What Affects Installation Cost Locally

Older properties across Oxfordshire and Buckinghamshire, particularly period cottages around Thame and Woodstock, often need the outer frame replaced rather than reused, because timber frames on older houses have usually moved or warped slightly over decades. 

For character properties like these, our cottage composite doors range is built specifically around that kind of frame and aesthetic. That changes depending on whether you’re in a conservation area; here’s why: some conservation guidance restricts frame material and colour, which can rule out a straightforward like-for-like swap.

Older Properties vs New Builds

New-build estates around Bicester and Aylesbury typically have standard-sized, true openings, so installation is usually a same-day job with minimal disruption and labour costs sitting near the £500 local starting point. 

Period properties can take longer, particularly where the frame has settled unevenly or where access for a skip or delivery van is restricted by an on-street parking permit zone. Commercial premises across the region tend to follow a different process altogether; our aluminium commercial doors page covers that separately.

Frame Replacement Considerations

This is where quotes usually start to diverge. Two installers quoting the same door can differ by £300–£500 purely on whether they’ve assessed the existing frame as reusable or not. Ask specifically whether your quote includes frame replacement or assumes a like-for-like fit; it’s rarely stated clearly on a headline price.

What Affects the Cost of Composite Front Doors?

Core material, colour and glazing, and installation complexity are the three factors that move composite front door cost the most. A solid timber core with bespoke glazing can cost nearly double a foam-core door in standard colour.

Core Material and Construction

Solid core construction improves both security and insulation compared with a foam-filled core, which is part of why it costs more. A thermally insulated core also reduces heat loss, relevant given the mix of older, poorly insulated housing stock common across both counties.

Foam Core vs Solid Timber Core

Foam-filled cores are lighter and generally cheaper, and perform well for most standard front-door use; they’re a common fit for our contemporary composite doors range, which suits new-build and 1930s properties well. Solid timber cores add rigidity and a heavier, more premium feel at the door, along with marginally better long-term resistance to warping, though the difference matters more on doors that face direct afternoon sun.

Colour, Glazing and Hardware

Standard RAL colours keep both cost and lead time down. Bespoke colours, decorative glazing, and upgraded hardware all add to the base price, sometimes significantly.

Standard vs Bespoke Colours

A bespoke colour, particularly a dual-colour finish with a different shade inside and outside, increases the base door price because it needs a separate finishing run. Standard colours from the manufacturer’s core range are quicker to produce and cost less, and our traditional composite doors range covers most of the classic finishes homeowners ask for without moving into bespoke pricing.

Glazing Upgrades and Decorative Glass

Decorative glazing increases overall price, and the increase scales with complexity; a simple frosted panel costs far less than a leaded or bespoke-pattern design. Worth deciding early, since it affects both price and lead time.

Handles, Letterplates and Security Add-Ons

• Bar handles typically cost more than standard lever handles
• Anti-snap cylinder upgrades add a modest amount but meaningfully improve security
• A Secured by Design specification, where offered, adds cost but may suit properties with a recent break-in history

Installation Complexity and Frame Replacement

As covered above, frame replacement is usually the biggest swing factor in composite door installation cost, larger than most homeowners expect going in.

Composite vs uPVC Doors: Cost Comparison

Composite doors cost 40–60% more upfront than uPVC, but generally last 30–35 years against 15–20 years for uPVC, with better security and insulation performance. Whether that trade-off is worth it depends on how long you plan to stay in the property.

Price Difference at a Glance

Long-Term Value and Lifespan

I’ve noticed that homeowners who plan to stay put for a decade or more tend to lean composite once they’ve seen this comparison, while those renovating to sell in the near term often go uPVC instead. The 40–60% upfront premium is real, and it typically balances out over the door’s lifespan through fewer replacements and better kerb appeal, but that’s a long-term calculation, not a same-year saving.

If you’re renovating a period property where kerb appeal and character matter as much as function, it’s worth weighing that against uPVC on more than price alone.

Getting an Accurate Composite Door Cost for Your Home

The only way to get a genuinely comparable composite door cost is a site survey; core material, glazing, and frame condition all shift the final figure enough that online ranges are a starting point, not a quote. If a front door replacement on a period property near Thame or Woodstock sounds like your project, checking current survey availability costs nothing and commits you to nothing.
