What Composite Prime does

Composite Prime is a UK-based manufacturer and distributor of composite decking, cladding, and fencing products, founded in 2014 in Leeds by Domenic Harrison (whose family founded Polypipe PLC) and Charles Taylor (a third-generation timber merchant). Its core technology is wood-plastic composite (WPC) extrusion, combining FSC-certified oak hardwood flour, recycled HDPE plastic, and UV stabilizer additives, with newer lines (Elements, Boardwalk) manufactured in the USA through a partnership with AZEK and Timbertech that introduces PVC and capped composite technology to the UK market. The product portfolio is organized into the Pro Solid Series (Elements, Redux, Boardwalk) and the HD Deck Range (HD Deck Dual, HD Deck 3D+, HD Deck X), complemented by Elements Cladding, Redux Cladding, HD Clad Pro, HD Fence, the Instant Deck pre-packaged kit, and the Prime Design 3D Deck Builder digital tool.

The business operates a channel-led, trade-focused go-to-market: products are sold through 300+ UK stockists (including exclusive agreements such as Arnold Laver for HD Deck 150) and hundreds of accredited installers, supported by a trade customer portal. End consumers engage with the company through free sample ordering, quote requests, and a stockist/installer finder on the website, with finance facilitated via an FCA-authorized partner. Customer segments span residential homeowners, trade landscapers, and commercial buyers (schools, care homes, golf clubs, hospitality). Revenue is generated through one-time product sales across decking, cladding, fencing, and accessories, with a small supplementary fee from finance plan activations, and pricing is quote-based rather than publicly disclosed. The company holds FSC certification, is a member of BALI, HTA, Timber Development UK, and APL, and won a 2024 RHS Tatton Park Gold Medal, and in 2024 announced its first geographic expansion beyond the UK.
