Successful exit for BGF, following Brisant Secure acquisition

Since partnering with BGF, the premium security hardware business has gone from strength to strength, and has now been acquired by Allegion plc.

13 August 2025

BGF has successfully exited its investment in Brisant Secure Limited, a leading designer and supplier of premium security hardware. The exit follows Brisant’s acquisition by global security and access provider Allegion plc, through one of its subsidiaries.

Headquartered in Dewsbury (West Yorkshire), with operations in Nottingham, Brisant was founded in 2013 by Steve Stewart, with Nick Dutton joining in 2014. Since its launch, the business has built a reputation for innovation and excellence in the fenestration and locksmith markets, with award-winning products, such as the Ultion Lock and Ultion Smart. Following continued growth, the company has played a pivotal role in raising industry standards for both security and aesthetics in residential door hardware.

BGF originally invested in Brisant in 2021, to support the company’s ambitious long-term growth plans and scale its market presence.

“BGF has been a true partner helping us to scale operations, to meet growing demand. Their input across leadership, strategy, supply chain, and acquisitions has been transformational, and has positioned us for long-term success.”

BGF’s value creation support was central to Brisant’s transformation during the investment period. Working in close partnership with the founders, BGF helped to strengthen the senior leadership team, as well as providing strategic support on acquisitions and supply chain diversification. BGF also introduced Colin Sykes as Non-Executive Chair, adding further depth to Brisant’s governance and strategic direction.

Seb Saywood, Partner at BGF, commented: “We’re incredibly proud to have partnered with Nick, Steve, and the wider Brisant team. We invested in the business to support its ambitious growth plans and help unlock new opportunities through continued innovation. Since then, Brisant has gone from strength to strength, investing in its people and expanding its product range, while delivering consistent growth and cementing its position as a leader in the market.

“At BGF, we’re committed to driving growth across the UK, by providing businesses with the capital and strategic support they need to succeed, and Brisant has done exactly that.”
