Cairngorm Capital Partners LLP (Cairngorm Capital) is pleased to announce that its portfolio company, Sentry Doors Holdings Limited (Sentry) has bought E. & S. W. Knowles & Company Limited (Knowles). This acquisition accelerates Sentry’s growth and confirms its positions as the UK’s leader in the timber fire safety and security doorset market.
Established in 1923, E. & S. W. Knowles manufactures specialist timber internal doorsets with fire rated, acoustic and PAS 24 security certification. Operating nationally from a 50,000 square foot facility in Birmingham, Knowles offers bespoke, sector specific solutions that meet the exacting requirements of its commercial, healthcare, education and leisure customers. Its commitment to regulatory compliance and high manufacturing standards has resulted in independent third party accreditations from both IFC and BM Trada1. Knowles employs approximately 100 people and in 2021, achieved revenue of £10m.
This acquisition adds new products that complement Sentry Doors’ well-established product range, focused on the specialist fire doorset requirements of the social housing, public sector, commercial and residential markets. The combination of these two firms provides both companies with opportunities for further innovation and growth. They share a commitment to manufacturing the highest quality fire safety solutions, are at the forefront of compliance and regulation but have minimal overlap in the industry sectors that they serve and their respective product ranges. Both companies will benefit from the possibilities offered by their new market sectors and an expanded range of products and finishes. The enlarged business continues to be headquartered in Doncaster. Steve Horner, Knowles’ Managing Director, will join Sentry’s senior management team, working with Ty Aziz, Sentry’s Chief Executive, to realise the potential that this partnership brings.
Stuart Whiteford, who led Cairngorm Capital’s team on this investment, said: Knowles is an excellent company that is highly regarded by its customers. The combination of Knowles and Sentry is strategically compelling and delivers additional capabilities and services across the business, to the benefit of all customers. Significant investments are taking place for both businesses and we look forward to supporting Ty Aziz and Steve Horner to deliver their growth plan.
Ty Aziz, Sentry’s Chief Executive, said: I am delighted to welcome Knowles to Sentry Doors – they have a fantastic manufacturing heritage, an exceptional team and a superb product range so we can learn a lot from one another. This partnership will help us to respond to the surge in demand for our products, as well as providing our customers with a fully comprehensive range of fire safety and security solutions, and a greater choice of features and finishes. It marks a key milestone in the growth strategy for our businesses and advances our collective ambition to be UK leaders in this sector.
Martin Wright, Knowles’ Chairman, added: Next year Knowles celebrates its centenary and while I am extremely proud of all that we have achieved in the last 99 years, I know that the company has the capability to achieve much more in the future. I believe that this is the natural point for me to pass the company to new, trusted custodians who can deliver on its future potential. Knowles has a perfect partner in Sentry and together, the companies should achieve great things.
Cairngorm Capital and Sentry were advised on this transaction by Grant Thornton (financial and tax), Drystone Strategy (commercial), Addleshaw Goddard (legal) and Thompson & Richardson (insurance). Knowles’ shareholders were advised by MHA MacIntyre Hudson (financial and tax) and Fladgate (legal).
