Sustainability perceptions drive satisfaction – DNA receives the highest sustainability rating in the mobile industry from business customers in the EPSI Survey

DNA achieved a score of 70.4 points in the 2026 Sustainability Index among business customers, clearly exceeding the industry average of 66.1 points. The Sustainability Index measures customers’ perceptions of companies’ environmental responsibility, social responsibility, and economic sustainability.

"A sustainable and reliable telecommunications infrastructure is the foundation of a well-functioning society. We have invested heavily in customer experience, and it is rewarding to see that our long-term work in sustainability, operational reliability, and meeting our customers’ needs is reflected in the assessments of our business customers," says Anna-Mari Ylihurula, Senior Vice President, Corporate Business at DNA.

According to EPSI Rating, customers associate sustainability in the telecommunications industry not only with environmental initiatives but also with operational reliability and the maintenance of society’s critical infrastructure.

Strong ratings for DNA in service quality as well

In overall business customer satisfaction, DNA scored 71.7 points and ranked second. The result was clearly above the industry average of 68.0 points, at a time when customer satisfaction across the industry declined compared to the previous year.

According to the study, DNA received the highest ratings from business customers in customer expectations, service quality, and value for money. In addition, DNA’s customer loyalty index reached 72.6, significantly above the industry average.

EPSI Rating’s 2026 telecommunications industry study is based on 2,196 interviews conducted between 2 and 22 September 2026. In the business customer sustainability index, DNA received 70.4 points, while the industry average was 66.1 points.
