Assemblin expands in security through acquisition of Säkra Fastigheter

Assemblin has acquired security company Säkra Fastigheter AB (“Säkra Fastigheter”) with 15 employees in Upplands Väsby, outside Stockholm, and annual sales of slightly more than SEK 30 million.


Säkra Fastigheter, which was founded in 2011, designs complete customised security solutions. The company currently comprises 15 dedicated security experts who design, install and maintain various security systems. The company offers services in alarms, locks, access systems, camera surveillance, fire alarms, emergency lighting, integrated systems, property systems, entrance intercoms and door automation, as well as information and booking systems. Customers include several housing companies, other enterprises, construction companies and tenant-owner housing associations.

“We are experiencing increased demand for security solutions. Säkra Fastigheter is a well-managed and profitable company with an extensive customer focus and superior service, and, in our assessment, it has considerable potential for growth. The company also has a substantial proportion of ongoing service agreements, offering predictability and stability. It is with great pleasure that we welcome Säkra Fastigheter’s employees and customers to the Assemblin family,” says Fredrik Allthin, CEO of Assemblin and Business Area Manager for Assemblin Electrical Engineering.

“We are very proud of the business we have built up and although we will continue to operate the company as we do today, it will be exciting to be part of a larger context. We look forward to being able to exchange experiences with Assemblin’s other security operations and, with their help, we will also be able to expand our business area,” says Björn Brovall, CEO of Säkra Fastigheter.
