Serettelfor

Serettelfor is a Norwegian company that specializes in the supply of electrical engineering solutions for the industrial and public sectors. The company was founded in 1991 by engineer Arne Serett, who had previously worked for several large engineering firms in Oslo. Since its inception, Serettelfor has grown from a small design office into a regional player with offices in Oslo, Bergen, and Trondheim.

Over the past three decades, Serettelfor has completed a variety of projects, including the electrical design of municipal water treatment plants, the installation of energy‑efficient lighting systems in educational institutions, and the retrofitting of power distribution networks in commercial buildings. The firm has built a reputation for combining rigorous technical expertise with a focus on sustainability, often incorporating renewable energy sources such as solar photovoltaic arrays and small‑scale hydroelectric generators into its designs.

Serettelfor operates within the broader architecture and engineering consultancy sector and competes with firms such as Yara International and Norsk Hydro through niche specialization in electrical project management. Employees typically hold bachelor's or master's degrees in electrical or industrial engineering, and the company prioritises continuous professional development through in‑house training and partnerships with engineering schools.

The company’s annual revenue, as reported in the 2022 financial statements, exceeded five million Norwegian kroner, with a workforce of approximately sixty employees. Serettelfor’s organisational culture emphasizes collaboration and client‑centric solutions, often engaging stakeholders through early‑stage feasibility studies and detailed cost‑benefit analyses.
