BGF exits Norfolk-headquartered bf1systems to Lagercrantz
Acquisition follows sustained product line expansion and operational development since minority investment in 2019.
19 August 2026
BGF has successfully exited its investment in bf1systems (bf1), a leading provider of high-performance sensing, measurement and integrated electronics solutions for the motorsport, automotive and aerospace industries.
The business has been acquired by Lagercrantz Group AB (STO: LAGR-B), a technology group active in niche markets mainly in Northern Europe, providing bf1 with an owner experienced in supporting specialist engineering and technology companies. As part of the transaction, bf1 will operate autonomously within Lagercrantz’ Control Division, which specialises in products and solutions for control and measurement.
Following BGF’s investment of £2.4 million in June 2019, bf1 has delivered consistent organic growth – increasing revenues to £17.8 million in the year to January 2026 – while broadening its customer base and deepening existing relationships with brands such as McLaren, Lamborghini and Porsche. With BGF’s support, bf1 also made the strategic acquisitions of KA Sensors and VPG Sim to expand the company’s product line, and sourced its Chair, Adam Robson, via the BGF Talent Network.
“bf1 has built strong momentum in recent years, supported by growing demand for our products and the continued development of our capabilities. BGF has been a hugely supportive partner over the past seven years, helping us broaden our product portfolio and accelerate our growth.”
James Welham
Managing Director, bf1
Founded in 1994 and headquartered in Diss, Norfolk, bf1systems designs, manufactures and distributes high-precision components used across motorsport and performance automotive applications. Its products include steering wheels, tyre pressure and temperature monitoring systems, force measurement components, and integrated electronics.
Building on the development of its core tyre pressure monitoring systems (TPMS) offering, bf1 delivers this product into major international motorsport series such as Formula 1, GT racing, IndyCar and the World Endurance Championship, and received a King’s Award for Enterprise in recognition of its TPMS technology.
“bf1 is a highly regarded British engineering business, with deep technical expertise and an established presence in the global motorsport industry. We have valued our long-term partnership with the business, supporting the team through a period of sustained growth. Lagercrantz is a strong strategic and cultural fit, and we wish James and the team every success in the next chapter.”
