Composite Warehouse: composite decking, fencing and cladding from Warrington

Composite Warehouse is a UK supplier of composite materials for gardens and outdoor spaces, operating from 27 Rufford Ct in Woolston, Warrington. Its catalogue is built around three core lines — composite decking boards, composite fencing panels and composite cladding — complemented by accessories and artificial grass. The company presents itself as a value-focused alternative to timber decking, with boards designed to imitate wood without the sanding, painting or staining associated with natural timber.

The product range

The decking line is organised into collections, including the Essential Collection, Timeless Collection, Aluminium, Concrete, Slatted Cladding and Woodgrain Cladding. Within the Essential Collection, the site listed grooved boards in black, dark grey and grey, plus a dark grey wood grain board, with prices shown per board at the time of writing this profile. Boards are described as fully recyclable, with a premium wood grain pattern and anti-slip properties.

Fencing is presented as the most recent addition to the portfolio. The panels are designed to be retrofitted into existing concrete fencing posts, allowing an outdoor space to be updated with low maintenance and a contemporary appearance. Cladding completes the exterior range, and the company also stocks accessories and artificial grass.

Testing, construction and warranties

According to the company, its boards were independently tested by Intertek against EN 15534 standards. The boards are engineered to a 22mm thickness with a 5mm square hollow, a structure the company says balances sufficient strength for a service life of over ten years with a weight low enough to support competitive drop-shipping prices. Warranty terms vary across the material: the site refers to guarantees of up to 25 years for its premium composite materials and to a 10-year warranty on the decking boards described in its about section.

Delivery, pricing and samples

Composite Warehouse offers free delivery on all boards to UK mainland addresses and states that it dispatches within 48 hours. It also advertises a price match on all products, promising to beat any like-for-like quote, and provides free samples so customers can check colour and finish before ordering. An online calculator gives estimates of the materials needed for a decking or fencing installation.

Installation and material notes

The company's guidance addresses two points it considers essential during installation: expansion and drainage. Composite products expand and contract, so gaps must be left to let boards move over their lifespan, and water must be able to run off rather than pool on the surface. On safety, the site states that composite decking has a low slip resistance with an average PTV of 33, which it classifies as a low to medium risk of slipping in wet conditions. On sustainability, it notes that composite material is manufactured using recycled wood and recycled plastics, reducing plastics in landfills.

How the company positions itself

Composite Warehouse describes itself as the UK's number one for affordability on decking, fencing and cladding, and attributes its approach to a market it says expanded sharply during the lockdowns, when a surge of new suppliers created wide variation in quality. The company says it spent years testing products alongside in-house expert Lee Smith, with the aim of making composite materials affordable for domestic and residential users while remaining durable and eco-friendly. It also states that customer feedback drives its range development, citing the fencing line as a response to demand for a durable and stylish alternative.
