Founded 1942

Rejlers was founded in the region of Småland, Sweden in 1942, and has been active as an consultancy firm ever since.

In broad outline, the company’s business has run alongside Sweden’s development as an industrial nation. Initially, the company was active in the expansion of the electricity supply network in Sweden.

After that, the company’s employees participated in the nation’s industrialisation and the mass housing initiative referred to as the Million Programme. Railway and telecommunications were added during the 1990s and 2000s. Environmental technology is being developed as a separate expertise during the 2010s.

Rejlers has retained the character of a family business and is now listed on Nasdaq Stockholm.
