For composite decking, you have a few choices, all of which are priced differently. To begin, you can install uncapped hollow core composite decking, which is the cheapest but weakest choice, cost of composite decking about £925 for 15 sqm on average.

Most homeowners are opting for wooden decking as their preferred decking material these days. This type of composite is designed to look like wood, but it requires very little upkeep and is incredibly long-lasting.

While wood was once the standard decking material, anyone contemplating constructing a deck should consider composite decking and the costs mentioned below.

Second, you can go for the uncapped solid core composite, which costs about £1,300 for the same surface area but is heavier and more expensive. Finally, for £1,600 for 15 square meters, you can choose a capped solid core composite.

Many landowners have a difficult time justifying the expense of wooden decking. Installing a high-quality timber deck can cost between $3.50 and $6.00 per linear foot, which is somewhat more than constructing with standard pressure treated timber, which can cost between $5.00 to $7.00 per (8′) floor. Comparing material and installation costs alone, though, does not tell the whole story.

The typical deck area is about 400 square feet. A rough estimate for pressure-treated (PT) pine timber would be about $3,000 for a 20’x20′ deck, while the same deck made with a high-quality composite wood would cost about $5,6001. In only 2-3 years of regular repairs, though, the cost differential is quickly erased.

Although no one likes to pay more for anything than they have to, there are a number of other factors that go into the actual cost of acquiring a commodity. Purchasing a higher-priced – but higher-quality – item begins to make sense as these “hidden costs” are considered.

Another fiber, PVC decking, has proved to be a good alternative to wood; however, it is a little flimsier than composite.


Where it comes to the manufacturing costs of the work, the price varies greatly depending on the material you choose. Instead of instructing the contractors to buy the materials on your behalf, you will find better offers by shopping for them yourself.

Before deciding on a type, color, or design, you can get a much better understanding of the various models, colors, and designs available.

Uncapped hollow core composite decking would cost about £35 per sqm, with materials costing £525 for a typical 15sqm region.

Solid structure composite is much more durable, and it comes in both capped and uncapped varieties. The capping is an additional layer of security that keeps mildew and mold from touching the boards, and it comes at a premium.

Solid core composite without a cap costs around £60 per sqm, while capped solid core composite costs around £80 per sqm.

PVC decking is less costly than solid core decking but more costly than hollow-core decking, costing about £40 per sqm.


Installing composite decking normally costs about £200 a day, which covers the labor costs of their employees.

On the first day, a significant portion of the time will be spent digging and leveling the earth in preparation for the decking supports to be installed. This can be a time-consuming operation, as any errors made at this stage can have a significant effect on the accuracy of the finished product.

Later in this report, we’ll go through the decking installation process and give you a better sense of what to expect from the decking contractors.

The products you chose are the first significant cost factor in building composite decking. Owing to the vast difference in consistency between hollow-core and solid-core treatment, their rates are drastically different.
