Award-Winning Local Company Joins Forces with Global Leader in Access Solutions

Doncaster-based Senior Architectural Systems, winner of the King’s Award for Innovation 2023, is the UK’s largest privately owned fenestration company. Today marks the next evolution for the business as the Swedish group ASSA ABLOY, a global leader in access solutions, has acquired 100% of the shares in the company. Senior Architectural Systems complements and extends ASSA ABLOYs current product offering into the commercial market in the UK and Ireland.

Founded in 1991 by the late Lennart Jonsson, Senior Architectural Systems has grown from humble beginnings into a market leader, renowned for its innovation and commitment to quality.

Under Lennart’s vision and the continued leadership of the management team, the company has built a strong industry reputation.

This acquisition marks the beginning of an exciting new chapter for the business,”

said Karen Jonsson, widow of Lennart Jonsson.

Mrs Jonsson added,

The Jonsson family and the board are pleased with the acquisition, believing ASSA ABLOY to be the perfect fit for the business. With both companies sharing a Swedish heritage and a commitment to innovation, this partnership will significantly strengthen and broaden Senior Architectural Systems’ reach.”

For Senior Architectural Systems it is business as usual, with no plans for substantial changes in the foreseeable future. Importantly you will see no change in the service, knowledge, and experience of every one of your contacts at Senior Architectural Systems. Our management teams are excited about the future and can see the benefit for the long-term interests of the business to be part of a larger, well-capitalised international group.

Mrs Jonsson emphasised that Lennart’s entrepreneurial spirit and dedication to excellence will remain at the heart of the company.

This acquisition honours his legacy by ensuring the company continues to thrive with a partner that shares the same commitment to innovation, quality, and the employees who have contributed so positively to its success.”
