What KS Composites does

KS Composites Ltd. is a UK-based advanced composite and GRP (Glass Reinforced Plastic) manufacturer founded in 1985 by Kelvin Smith and now led by second-generation Managing Director Jamie Smith. Operating from a 48,000 sq ft purpose-built facility in Old Dalby, Leicestershire, the company delivers end-to-end composite manufacturing services spanning design (CATIA-based office with FEA and CFD), tooling, prototyping, autoclave curing, 5-axis CNC machining, assembly, and quality assurance to ISO 9001:2015. It serves enterprise clients primarily in motorsport (including F1 front wing packages and race car bodywork) and high-end automotive (Jaguar Land Rover Project 8, Hennessey Venom F5, Revolution A-One), with additional projects in aviation, defence, marine, energy (including wind turbine components), rail, athletics, and classic/racing car restoration. The business operates on a project-based, quote-driven pricing model with revenue derived from bespoke one-off solutions and select mass-production programmes delivered through direct enterprise technical partnerships.

The company monetises through three primary streams: bespoke composite manufacturing for prototypes and development projects, mass production manufacturing for higher-volume composite components, and embedded technical consultancy that spans design assistance, FEA/CFD analysis, and full engineering support. Customer acquisition is almost exclusively direct B2B enterprise sales built on four decades of motorsport and automotive reputation, with no e-commerce or self-serve channels. The customer base is anchored by long-tenured relationships, including Tony Thompson Racing (since the 1980s), Jaguar Land Rover (formal partnership since 2011, Project 8 production supplier), and multi-season Formula 1 technical partnerships, alongside newer programmes such as the 2025 collaboration with CompPair and SHD Group on an F1 Sustainability Showcase Car. Distribution is global in reach but UK-and-Europe-centric in execution, relying on technical reputation and word-of-mouth within specialised motorsport and high-performance engineering circles rather than active outbound marketing.
