Composite Door Price Calculator
Use our composite door price calculator to check the main cost factors for your new made-to-measure composite door. Whether you need a new front door, back door, stable door, solid core composite door, aluminium composite door, FD30 external fire door or a smaller door for a narrow opening, this calculator helps you send the right details to Colin’s Sash Windows for an accurate price.
Composite door prices can vary depending on the door type, size, frame layout, colour, glazing, hardware, security upgrades and whether you need supply only, delivery or supply and fit. Instead of giving a rough price that may not match your final specification, our calculator collects the important details first and sends them to our team for review.
If you already know what you want, complete the calculator above and we will send your real made-to-measure price. If you want to design the door yourself and order directly online, you can also use our Composite Doors Design & Order Online tool.
How Our Composite Door Price Calculator Works
Our calculator is designed to make the quoting process simple. You do not need to know every technical detail before starting. The calculator guides you through the main choices that affect the final price, including door type, project type, measurements, frame configuration, style, colour, glazing, hardware, security and service option.
Once submitted, our team will review your selected options and contact you with a real price based on your door specification. This gives you a more useful result than a generic online estimate because your quote is based on your actual requirements.

Exterior Composite Door Price Calculator
This page can also be used as an exterior composite door price calculator. Most composite doors are fitted as external entrance doors, including front doors, back doors, stable doors and external fire doors.
Exterior composite door prices depend on more than just the door slab. A full doorset can include the frame, threshold, weather seals, glazing, locking system, hinges, hardware and any side panels or top box. This is why the calculator asks for the complete door layout before sending your enquiry.
Exterior composite doors are commonly used for front entrances, rear entrances, kitchen doors, garden access, utility rooms, porches, side entrances, flats, apartments and properties requiring FD30 external fire doors.
If you are comparing external door options, you can also view our full composite door types range.
Composite Front Door Prices
Composite front doors are one of the most popular choices for UK homes because they offer strong security, good insulation, low maintenance and a wide range of styles. Our GRP composite doors include traditional and modern designs, with listed styles starting from around £631 depending on the design.
The price of a composite front door can change based on the door design, external colour, internal colour, frame colour, glass style, handles, hardware, security upgrades, side panels, top box and whether you need supply only or installation.
Use the calculator to select your preferred style and send the details to our team for a made-to-measure price.
Double Composite Door Price Calculator
If you are looking for a double composite door price calculator, the most important thing to check is the full frame layout. Some customers use “double composite door” to describe a wider entrance door set, a door with side panels, or a door with both side panels and a top box.
Inside the calculator, you can choose frame layouts such as Standard Door, Right Side Panel, Left Side Panel, Both Side Panels, Top Box, Top Box with Right Side Panel, Top Box with Left Side Panel and Top Box with Both Side Panels.
These wider layouts usually cost more than a standard single composite door because they include more frame sections, more glass and more made-to-measure manufacturing. If you need a larger entrance door design, choose the closest frame layout in the calculator and add any extra notes at the final step.
Composite Back Door Prices
Composite back doors are ideal for kitchens, rear entrances, garden access and utility rooms. They are designed to offer security, insulation and long-term performance while still giving you style and colour options.
Our composite back doors include several listed styles and colours, with many options shown around the £656 to £677 starting price range. The final price can still vary depending on the exact design, glazing, frame choice and whether fitting is required.
Use the calculator above and choose Composite Back Door if your enquiry is for a rear entrance, garden door or utility door replacement.
Composite Stable Door Prices
Composite stable doors are split horizontally, allowing the top and bottom sections to open independently. They are often chosen for cottages, country-style homes, kitchens, rear entrances and homes where ventilation is useful while keeping children or pets safely inside.
Our composite stable doors currently show prices from around £1,055, depending on the design, colour and glazing style.
Stable doors are usually more specialist than a standard single composite door, so the final quote should be based on your exact size, design and installation requirement. Select Composite Stable Door in the calculator to start your stable door quote.
Aluminium Composite Door Prices
Aluminium composite doors are a premium option for homeowners who want a modern entrance door with strong performance, weather resistance and low maintenance. They are often chosen for contemporary homes, exposed locations and customers who want a higher-end door finish.
Our aluminium composite doors offer extensive colour, hardware and glazing choices. The final price depends on the style, frame, finish, glazing, accessories and installation requirements.
Because aluminium composite doors are more specification-led, the calculator is the best way to send your project details for review.
Solid Core Composite Door Prices
Solid core composite doors are designed for customers who want a more robust, secure and substantial door. These doors use a solid timber core rather than a standard foam-filled centre, giving a heavier and more premium feel.
If you want a stronger entrance door with solid-core construction, visit our Solidor composite doors page or select Solidor / Solid Core Composite Door in the calculator.
The final price can depend on the door design, glazing, colour, hardware, security options and whether you need supply only or fitting.
FD30 External Composite Fire Door Prices
FD30 external composite fire doors are specialist doors for properties where fire performance is required. They are often used for flats, maisonettes, HMOs, properties with integrated garages and other projects where an external fire-rated door is needed.
Our FD30 external composite fire doors include solid and glazed fire door options, with listed prices starting from around £1,035 and going higher depending on the style and glazing.
Fire door pricing can depend on the door style, fire rating, glazing, closer requirements, certification and project details. Select FD30 External Composite Fire Door in the calculator so our team can review the correct specification.
Small Composite Door Prices
Some older UK homes have smaller or narrower door openings. A standard composite door may not fit these properties without structural work, which is why a made-to-measure smaller composite door can be a better solution.
Our small composite doors are designed for reduced openings, including doors from 1650mm high. They are suitable for cottages, Victorian terraces, farmhouses, period renovations, rear entrances and porches.
If your opening is low, narrow or unusual, select Small Composite Door in the calculator and enter your approximate width and height. Our team can then review the best option for your property.
What Affects Composite Door Prices?
Composite door prices are affected by several specification choices. This is why two doors that look similar online can have different final prices.
The main cost factors include door type, width, height, specialist sizing, frame configuration, door style, door colour, internal colour, frame colour, glazing type, side panels, top box, hardware suite, letterplate, knocker, spyhole, bar handle, locking system, security upgrades, delivery area and whether you need supply only or supply and fit.
A simple standard GRP composite front door will usually be priced differently from a stable door, FD30 fire door, solid core door or double composite door layout with side panels. This is why our calculator collects your full specification before our team sends the price.
