Global security group Allegion has bought Brisant Secure, the UK-based lock and door hardware specialist, in a deal that further consolidates the UK security sector.
Allegion, listed on the New York Stock Exchange, announced the acquisition through one of its subsidiaries, describing Brisant as a leading innovator in residential security hardware. Founded in 2011, Brisant is best known for its Ultion brand of premium high-security lock cylinders, alongside a wider range of mechanical and electronic locks and door accessories.
The takeover comes less than four years after growth capital investor BGF backed Brisant, helping to drive its expansion. Since investing in 2021, BGF said it had supported the business with acquisitions strategy, supply chain diversification and management development, which helped broaden its award-winning product portfolio. It described the Allegion deal as a “brilliant result” for co-founders Nick Dutton and Stephen Stewart and the wider team.
For Allegion, the deal adds another high-profile British security business to its international operations, following its recent purchase of Manchester-based UAP Limited. The company said Brisant would complement its non-residential product range in the UK and give it greater reach in residential markets.
Tim Eckersley, Allegion’s senior vice president and president of Allegion International, welcomed Brisant into the group. “Brisant’s premium, patented solutions are a natural complement to Allegion UK’s best-in-class product and service capabilities,” he said. “We are thrilled to strengthen our European portfolio with yet another leader and innovator in our industry.”
Brisant’s managing director, Kevin Harvey, will remain with the business after the acquisition. He said joining Allegion marked “an exciting evolution” for the firm. “Not only are we expanding our strategic partnerships and scale, but we’re now part of a global leader that’s known for innovating to make the world safer while also driving strategic growth.”
BGF, meanwhile, is celebrating its second successful exit in as many days. The investor said Brisant’s rapid scaling highlighted the role it can play in supporting entrepreneurs beyond capital. BGF Midlands team members Sebastian Saywood, Jonathan Earl and Kyle Long led the deal.
For Brisant, now part of a global group operating in more than 130 countries, the move offers new scale and resources in a competitive market. For Allegion, it extends a strategy of snapping up UK-based innovators in door and security technology to deepen its international presence.
