While composite decking prices tend to be higher upfront than the prices of traditional wooden decks – this innovative solution offers a profitable long-term investment. This modern decking solution is not only highly durable and long-lasting, but also visually appealing and requires very little maintenance. However, before starting any decking project, it's important to understand how composite decking prices are determined and what factors influence the final cost. In this article, we’ll cover everything you need to know.

How Are Composite Decking Prices Calculated?

Composite decking prices are usually quoted per square metre by manufacturers and retailers. However, this price often only includes the cost of the decking boards themselves. Additional components – such as the subframe, fasteners, edge trims, and delivery fees – are typically charged separately. As a result, composite decking prices can initially appear lower than the actual total cost.

Several factors influence the final price. Solid composite decking boards tend to be more expensive than hollow ones. It also matters whether the boards are made from recycled or virgin materials. The size of your project plays a major role too – larger decking areas require more material, but bulk purchases often come with discounts. Labour costs and delivery fees further add to the total cost.

In the UK in 2025, the cost of composite decking materials typically ranges between £40 and £90 per square metre, depending on quality and brand. If installed professionally, the total cost per square metre (including materials, substructure, and labour) can reach around £100 to £150.

Key Cost Factors of Composite Decking

The development of composite decking prices is influenced by several components, with material quality being the most important. Higher-end boards typically offer longer lifespans, better UV resistance, and more consistent colour retention. These are often thicker, denser, and produced using premium manufacturing methods. In contrast, cheaper versions tend to be thinner, more fragile, and more susceptible to warping or fading over time.

Surface finish also affects the final cost. Brushed or woodgrain-patterned surfaces generally cost more – especially if they offer slip resistance or extra UV protection. The installation method is another important factor. Hidden clip systems provide a cleaner, more modern look, but are often more expensive than traditional screw fixings. The subframe material – whether timber, metal or recycled plastic – also impacts pricing.

Additionally, many manufacturers offer varying warranty lengths, which can also influence the price. Products with longer warranties tend to be more reliable, but understandably cost more upfront.

Composite Decking or Real Wood?

Many homeowners debate between composite decking and real wood, especially in terms of cost. Real wood may appear cheaper at first, but often costs more in the long run due to the maintenance it requires. Annual oiling, sanding, and surface treatments can consume both time and money.

Composite decking, by contrast, requires virtually no maintenance and can last 20 to 30 years. So while composite decking prices may be higher initially, it often proves to be a more economical choice over time.

In terms of aesthetics, wood offers a natural and varied look that appeals to many. But composite decking has advanced to the point where it can closely mimic the appearance of timber. From an environmental perspective, composite decking often uses recycled materials, while real wood can contribute to deforestation if not sourced responsibly.

Tips for Reducing Composite Decking Costs

If you're looking to reduce your composite decking prices, consider a few practical strategies. The first is careful planning. A precise layout based on accurate measurements helps avoid over-ordering, which can lead to unnecessary expenses. Buying outside of peak season can also lower costs. In the UK, many suppliers offer discounts during the winter and early spring months.

Look out for bundle deals where decking boards, fixings, and substructure elements are sold together – these are often more cost-effective than buying each component separately. And if you have basic DIY skills, doing the installation yourself can help you avoid labour costs, which can be one of the biggest expenses in a decking project.

Conclusion

Composite decking prices depend on many factors: the type of material, the size of the project, the installation method, and of course, the brand you choose. Composite decking prices are much more than a simple cost per square metre: they reflect a complex calculation based on many considerations.

While composite decking may carry a higher upfront cost than traditional timber, it is often the more economical, sustainable, and low-maintenance choice in the long term.

With careful planning and the right approach, you can save money and still achieve a stylish, durable, and eco-friendly solution for your outdoor space.
