A number of Prosero companies are customers as well, and now their cooperation with El & Fastighetsdrift can be intensified in a variety of areas.

The great demand for these services has resulted in very profitable growth for many years, including 2021; turnover for last year is expected to amount to SEK 42 million. The company has 24 employees working from the office in Älvsjö, Stockholm.
