ISS to acquire Tomagruppen

ISS has announced it has reached an agreement to acquire Tomagruppen AS, a Norwegian, majority family-owned facility services company.

Founded in 1978, Tomagruppen delivers cleaning, catering, property management, and other support services to the public and private sectors. The company operates in Norway and Denmark, with the vast majority of operations in Norway. In 2025, Tomagruppen’s total revenue was approximately DKK 1.8 billion (£208 million).

The acquisition of Tomagruppen further reinforces ISS Norway’s position among the market-leading facility services providers in Norway, while adding further scale and know-how to ISS Denmark’s position across sectors.

Commenting on the acquisition, Kasper Fangel, Group CEO of ISS, said: “We are excited to announce this agreement, welcoming more than 4,000 new colleagues – as well as new customers. Beyond expanding our presence in the Nordic region, this bolt-on acquisition is a strong strategic fit with ISS’ well-performing business in both Norway and Denmark. It will drive efficiencies and unlock clear synergies, while enabling us to further scale and enhance our integrated facility services (IFS) offering for customers across the region. We very much look forward to welcoming Tomagruppen into ISS.”

Frode Monsen, Group CEO of Tomagruppen, commented: “For Tomagruppen, this is an exciting milestone. We are very proud of what we have built, and we look forward to becoming part of the ISS Group. Together, we can strengthen our offering to customers and create new opportunities for our employees and partners in the years ahead.”

Completion of the transaction is subject to customary regulatory approvals.
