Upgrading your external doors? If so you have probably been researching online, or maybe even lusting enviously over your neighbour’s front doors. Either way, you are probably comparing prices, materials and wanting to find out just how much composite doors are in the UK.
As always, our team is here to help answer all your door questions. Composite doors are generally priced between £1000 and £2,500+ fully fitted, but of course, this all depends on the design, door size, required hardware, and installation requirements. Supply-only options can start from around £1000, while premium, fully customised doors can exceed £3,000.
The door price depends on far more than just the door itself. From thermal insulation and energy efficiency to security features and side panels, several factors influence the final cost.
Let’s break everything down, so you understand exactly what you’re paying for, and how to get the best value.
Average Composite Door Prices in the UK
Yes, composite doors may be on the higher end of door costs, but when comparing door types, you will quickly see that they offer many advantages in durability, security, and overall performance, which warrant the higher cost compared to some other options.
Typical Composite Door Price Breakdown
| Door Type | Supply Only | Supply & Fit |
| Entry-level GRP composite | £1000–£1500 | £1250–£1,400 |
| Mid-range composite | £1200–£1500 | £1,500–£2,000 |
| Premium composite | £1,500–£3,000+ | £2,000–£4,000+ |
Most homeowners and our customers opt for supply and fit, as this ensures the door is fitted correctly and works as it should. If any issues do arise down the line, Door Warehouse offers a 10-year workmanship guarantee along with the manufacturer’s warranty for extra peace of mind.
What Affects the Cost of a Composite Door?
Every door and every door installation is different, which is why there isn’t a single fixed price. Here are the main factors that influence the final cost.
Door Size & Bespoke Requirements
Standard sizes are more cost-effective because of supply and demand, but many homes require made-to-measure doors. If you don’t have a standard door frame size, for example, if you live in an older house, or you have done renovations which have left you with different-sized door frames, you should expect to pay a higher price. This is simply because of the limited availability of custom sizes or the need for custom manufacturing.
Design & Variety of Styles
Composite doors are available in a variety of styles, including:
- Traditional panel designs
- Contemporary composite styles with clean lines
- Cottage and stable doors
- Fully glazed or part-glazed options
More intricate designs, decorative glazing or bespoke finishes will naturally increase the price.
Colour & Finish Options
Standard colours are usually included, but premium finishes such as:
- Anthracite grey
- Woodgrain effects
- Dual-colour options
can increase the overall door price.
Glass & Glazing Options
Glazing plays a big role in both cost and performance.
Options include:
- Decorative glass panels
- Frosted privacy glass
- Double-glazed units
- Energy-efficient glazing
Larger glass areas or premium designs will add to the overall costs, but on the upside, they will improve natural light and kerb appeal of your home.
Side Panels & Additional Features
Adding side panels or top lights can make your composite door more expensive, but they also create a more impressive entrance and allow you to drench your indoor space with natural light.
They are ideal for:
- Wider door openings
- Letting in more natural light
- Creating a grander front door design
Security & Locking System
You can’t get much more secure than a composite door, typically featuring multi-point locking systems, high-security cylinders and anti-snap locks for added protection. While opting for higher security specifications can increase the overall cost, it’s a worthwhile investment. Paying a little more up front can significantly enhance your home’s safety and provide long-term peace of mind.
Door Hardware & Furniture
Your choice of door hardware and door furniture also affects your final price.
This includes:
- Door handles
- Letterplates
- Knockers
- Hinges
Premium finishes such as matte black or satin brass can increase the overall cost but really improve the final look of your door.
What Are Composite Doors Made From?
Composite doors are made using a combination of materials designed to maximise strength, durability and insulation. Typically, this includes a solid core for structural strength, insulating foam layers to improve thermal efficiency, and a durable outer skin made from glass-reinforced plastic (GRP). Together, these create a secure, energy-efficient, and long-lasting door that consistently outperforms traditional alternatives.
Composite Doors vs uPVC Doors
If you are shopping for external doors, it’s normal to compare different options. A popular alternative to composite doors is uPVC.
uPVC doors are cheaper overall than composite doors, and modern options are safe, they just don’t have the same security edge that composite doors do and are less durable over time.
Composite doors are more expensive but stronger and more secure, whilst offering better thermal insulation and overall energy efficiency. Not to mention, a composite door will outlive a uPVC door by quite a few years, so really the higher initial cost will still provide a good return on investment over the course of its lifetime, with less maintenance overall too!
Are Composite Doors Worth the Price?
In most cases, yes, composite doors offer excellent value for long-term performance. Yes, the price is higher than a standard door, but the benefits and long-term gains outweigh the initial cost. Plus, they last for years, so you won’t have the additional replacement cost to think about.
Composite doors offer excellent all-round performance, combining energy efficiency, security, durability and visual appeal. Their insulated core helps reduce heat loss, improving thermal efficiency and lowering your energy bills.
If security is a concern for you, advanced multi-point locking systems and anti-snap technology provide a high level of protection.
Unlike traditional timber doors, composite doors are highly durable and won’t warp, crack or rot over time, even in harsh weather conditions. They also require very little maintenance, with no need for regular painting or treatment. On top of this, they are available in a wide range of styles, colours and finishes, making it easy to achieve the right look for any property. A win all round.
Supply Only vs Supply & Fit
One of the biggest decisions when buying a new door is whether to choose supply only or a full installation service. Supply-only can offer a lower upfront cost, but it requires you to arrange your own installer and carries the risk of incorrect fitting, which can affect performance. In contrast, a supply and fit service ensures the door is professionally installed, correctly aligned and properly sealed, often including removal of the old door and a warranty for added peace of mind. At Door Warehouse, we strongly recommend supply and fit, as even the highest-quality door will not perform as intended if it isn’t installed correctly.
How to Get the Best Value for Your Budget
If you’re looking to maximise value here, here are some tips to make sure you get the most out of your spend:
- Avoid the cheapest options; quality matters
- Choose trusted brands and materials
- Consider long-term performance, not just upfront cost
- Bundle doors and hardware where possible
Investing in a high-quality composite door will save you money over time through improved durability and efficiency.
