Browne Jacobson advises on sale of premium security hardware company Brisant Secure to Allegion

20 August 2025

Browne Jacobson has successfully advised the shareholders of Brisant Secure Limited, a premium security hardware business, on its sale to Allegion Investments (UK) Limited, a subsidiary of NYSE-listed global security provider Allegion plc.

The transaction represents a successful exit for Brisant, including equity investor BGF, and other shareholders following strong growth at Brisant Secure. Headquartered in Dewsbury, West Yorkshire, with operations in Nottingham, Brisant was founded in 2013 by Steve Stewart, with Nick Dutton joining in 2014. The business has built a reputation for innovation and excellence in the fenestration and locksmith markets, with award-winning products including the Ultion Lock and Ultion Smart.

The Browne Jacobson team was led by Corporate Partner Mark Hughes, with support from Sian Rose, Principal Associate, and Lydia Mills, Associate. Principal Associate Rebecca Burge provided specialist tax advice on the transaction.

Mark Hughes, Partner at Browne Jacobson, commented: "We are pleased to have advised Brisant's shareholders on this successful exit. Having worked closely with Brisant for a number of years, it has been rewarding to see this business grow, and support it and its shareholders through this sale to Allegion, a New York Stock Exchange listed global leader in security products and solutions."

The acquisition strengthens Allegion's position in the UK security market and provides Brisant with the resources and global reach to accelerate its growth plans.

Key projects in the manufacturing and industrials sector include UAP’s sale to AllegionNottingham’s Orrsum joining global chain Li & Fung, and international backing for UK gin company Warner’s Distillery
