Case Study: Nuon achieves higher customer satisfaction and loyalty with Cognizant's customized online energy-rate selector

Customized Tool Enables Customers to Select Energy Rates Online

Nuon, a major energy supplier serving about 1.9 million buildings across EMEA, faced a highly competitive market where customers are increasingly willing to switch providers. To win and retain business it needed a responsive online platform that reflected its “in good hands” brand while accommodating diverse customer preferences—low cost, sustainability, hands‑on help or no‑contact options—and made switching or selecting rates simple and transparent.

Cognizant’s Mirabeau built a user‑tested Nuon.nl using a custom Product Selector and Episerver CMS to deliver personalized, transparent rate choices and a consistent cross‑device experience. The result: higher customer satisfaction and stronger loyalty through dynamic, user‑driven customization, faster content rollout and a measurable positive impact on Nuon’s daily business while reinforcing the brand promise.
