For 60 years, BM Catalysts has stood as excellent example of British manufacturing. Founded in Nottinghamshire, England, the company has grown from its local routes into Europe’s leading manufacturer of aftermarket hot end emissions products, while remaining firmly committed to producing on home soil.
During growing global supply chain uncertainty and many manufacturers opting to shift production overseas, BM Catalysts continues to invest in Britain. It is a commitment that not only reflects confidence in British industry but a belief that quality, accountability and service are best achieved through complete control of manufacturing processes.
BM Catalysts operates four high-tech manufacturing facilities across the UK, boasting an impressive 214,000 square foot of production space. With expansion plans underway to see this rise by a further 60,000 square feet, further strengthening manufacturing capabilities and reinforcing a long-term commitment to UK industry.
Within these facilities, every critical stage of production is carried out in-house. From CAT assembly and pipe bending to welding and part development, BM Catalyst maintains direct control of the processes that define product quality. This approach enables the production of over 500,000 units annually while maintaining the highest standards BM Catalysts prides itself upon.
Keeping production in Britain delivers more than pride but provides complete control. Every part manufactured by BM Catalysts carried a unique serial number, ensuring full manufacturing traceability through its lifecycle. This level of accountability enables quality assurance and gives partners confidence that BM Catalysts’ products have been manufactured with the very finest of details in mind, with every stage of production fully documented.
This commitment to British manufacturing also allows BM Catalysts to better support fellow UK business. With extensive stock holdings of more than 80,00 at any given time ensure products are readily available. Coupled with next-day delivery on leading emissions products and premium AM delivery services that ensure parts arrive before midday, BM Catalysts provides reliability and responsiveness that motor factors and distributors depend upon.
Ultimately, everything BM Catalysts does is driven by the purpose of supporting the aftermarket with high-quality, efficient and dependable emissions control solutions. By designing and manufacturing suitable products that are compliant with the latest emissions legislation in Britain and beyond, BM Catalysts can consistently meet the evolving needs of the industry whilst exceeding expectations.
Through continued investment in UK manufacturing, unwavering attention to quality and determination to support the automotive aftermarket, BM Catalysts demonstrates that British-made still represents excellence, integrity and innovation.
