About us

Big ambitions.
Excellent deliveries.

Imtech has a new name.

Assemblin is a complete installation and service partner with operations in Sweden, Norway and Finland. With the strength of a multidisciplinary group and the personal presence of a local company, we design, install and maintain technical systems for heating and sanitation, electricity and ventilation in offices, arenas, shopping centres, houses and industrial premises. Our turnover is more than SEK 7 billion and with more than 5,000 employees in over 100 locations in the Nordic region, we are where you are. For you.


Work environment

Assemblin will ensure a safe work environment and tackle issues on an ongoing basis to develop the work environment from both a physical and psychosocial perspective. All operations must comply with Assemblin’s work environment and environmental policy.


Assemblin will give environmental considerations a major place in all its operations. We will develop our expertise to monitor the environmental and climate impact in all our operations and on behalf of our customers. This includes the expertise to find solutions that are effective in terms of the environment and the climate from a life-cycle perspective.


Society is developing towards increased cultural, social and religious diversity. Assemblin’s aim is to continually improve, and this is reflected not least in our recruitment.


Assemblin’s operations are driven by technical and installation companies in Sweden, Norway and Finland. The operations in Assemblin are decentralised and held together though a joint management, shared support functions and shared approaches.

Assemblin must interact with the customer’s organisation with sufficient knowledge and experience. Reporting and documentation in accordance with contracts must be conducted with a high level of quality. The group’s organisation starts at departmental level. The organisation is reviewed and revised when necessary, though on at least one occasion per year.

 Our strategy is based on specialisation and operations in each country are therefore also organised in different technical areas. Throughout Sweden, we are locally organised into branches that you can find on our contact page.
