If you’re planning to transform your outdoor space with a long-lasting decking solution, aluminium decking should be at the top of your list.
Aluminium decks are gaining popularity in the UK for their modern look, low maintenance, and unbeatable longevity.
But how much does it actually cost to build an aluminium deck? Let’s break it down.

The Basics: Why Choose Aluminium Decking?
Aluminium decking offers a host of benefits compared to traditional materials like timber or composite. It’s lightweight, weather-resistant, fireproof, and requires minimal upkeep. Unlike wood, it won’t warp, rot, or attract pests. And unlike plastic decking, aluminium can handle high foot traffic and extreme temperatures without cracking or fading.

Material Costs: What to Expect
The cost of aluminium decking varies depending on the quality, brand, and finish. On average, you can expect to pay between £30 and £150 per square metre for aluminium decking boards.
Premium options, such as powder-coated or anodised finishes, may sit at the higher end of the scale.
If you’re in the market for high-quality aluminium decking boards, Trade Warehouse offers an extensive range of options at competitive prices. Take a look at our collection of aluminium decking to find the perfect match for your project.

Labour and Installation Costs
Labour costs for installing an aluminium deck typically range from £50 to £100 per square metre.
These costs can vary depending on the complexity of the design and your location in the UK.
Factors like curved edges, multi-level designs, or intricate railings may increase the cost.
One advantage of aluminium decking is its lightweight nature, which makes it easier and quicker to install compared to traditional materials.
That means labour costs are often lower, saving you money in the long run.
For DIY enthusiasts, our range of essential tools simplify installation. For example, the Stainless Steel Starter Clips for Aluminium Decking provide a secure and hassle-free way to get started.
Substructure and Additional Features
A strong substructure is vital for the longevity and safety of your deck. Depending on the size and complexity of your project, substructure materials can add another £500 to £1,500 to the overall cost. Aluminium is often preferred for substructures due to its strength and resistance to weathering.
You’ll also want to factor in additional features like railings, steps, and trims. Trade Warehouse offers stylish finishing touches, such as their 2.2m Aluminium Corner Trim, which add both style and durability to your deck.
Maintenance Costs: Minimal and Affordable
One of the standout benefits of aluminium decking is its low maintenance requirements.
Unlike timber, which needs regular sealing and staining, aluminium only requires occasional cleaning to keep it looking its best. This not only saves you money but also time.
To keep your deck in pristine condition, we have created a detailed guide on the Essential Tools and Products for Maintaining Aluminium Decking Boards.
By following these tips, you’ll ensure your investment remains in top-notch condition for decades.
Aluminium Decking vs Traditional Decking Materials
While aluminium decking might have a higher upfront cost than timber or composite, its longevity and durability make it a cost-effective choice in the long term.
With a lifespan of up to 100 years, you won’t have to worry about costly repairs or replacements.
In contrast, timber decking typically lasts 10–20 years and requires regular maintenance, while composite decking can fade or warp over time.
Aluminium decking’s resistance to fire, rust, and pests gives it a distinct edge, especially for high-rise balconies and terraces where safety is paramount.
Design Flexibility and Aesthetic Appeal
Aluminium decking doesn’t just deliver on performance—it also looks fantastic. Available in a range of finishes and colours, aluminium decking can complement any architectural style, from contemporary homes to traditional properties.
For a sleek and modern finish, consider pairing your decking with matching accessories from Trade Warehouse’s collection of aluminium decking products.
