What WJ Group does
WJ Group is a UK-based specialty timber engineering and treatment company founded in 2007 and headquartered in Hull, East Yorkshire. It operates through three wholly-owned subsidiaries — WJ Components Ltd (timber engineering), WJ Timber Treatments Ltd (preservative treatments), and WJ Fire Retardant Ltd — delivering preservative, fire-retardant, and anti-slip timber treatments alongside manufactured engineered components such as roof trusses, I-beams, glulam beams, CNC-machined parts, and a patented timber caravan chassis.
The company's core technology centres on proprietary chemical treatments: the FireWright brand uses an all-natural, biodegradable fire-retardant powder dissolved in water achieving Euroclass B s1, d0 classification, while the DeckWright brand applies road-traffic-grade resin technology achieving a Pendulum Test Value of 71 under BS 7976:2002. Engineering capabilities include CNC router machining, specialist kiln drying, and a patented timber chassis (GB202307097A) offering a sustainable alternative to steel with carbon footprint of approximately -42kgCo2e versus 1700kgCo2e for steel equivalents.
WJ Group generates revenue primarily through per-cubic-metre and per-unit treatment fees for preservative, fire-retardant, and anti-slip services, one-time component sales to caravan and leisure home manufacturers, bundled timber haulage via an in-house HGV fleet, and merchant-channel resale. The company operates five UK facilities (Hull x3, Rochester, Kirkburn, and Port of Creeksea in Essex, the latter via a 2025 partnership with Baltic Distribution) positioned near major ports to serve timber importers, construction firms, holiday park operators, leisure home manufacturers, and merchants across England, Scotland, and Northern Ireland.
