Customer satisfaction survey
We strive for continuous improvement to better serve our customers. To that end, we carry out regular customer satisfaction surveys. The surveys are conducted by a qualified independent third party to ensure anonymity and to find out how our customers truly feel about us.
Our latest survey was conducted in January–February 2026 by Pajakon Oy. In the 2026 survey, KL-Lämpö's Net Promoter Score (NPS) was 62, which marks the highest NPS score in the company’s ten-year measurement history. KL-Lämpö's overall customer satisfaction was rated at 4.3 (5 being the maximum score).
The most popular adjectives used to describe KL-Lämpö were reliable, high-quality and specialist. We intend to live up to these attributes.
