A rapidly growing family business

WEST Invest Group is a rapidly growing family business with more than 60 years of history. Our story begun in 1959, when Helmer and Doris Viiala established a company called Höyrytys in to provide local steam and heating services.

Since October 2022, the company has operated under the name WEST Invest Group Oy, and the ownership is today concentrated in the hands of the third generation of the Viiala family.
