Simplifying energy choices for homes and businesses
Hesi is a leading sustainable energy provider serving 25,000+ customers across the Netherlands and Germany. While the business carried decades of credibility, the website didn’t reflect it. The experience felt dated and cluttered, making it harder for customers to understand services or take action.
The brief was clear: modernise the brand within existing guidelines, simplify key journeys, and increase conversion, without disrupting the trust of loyal, existing customers.
In close collaboration with development, we transformed the site into a cleaner, conversion-focused experience built around clarity and trust. The results followed: phone enquiries increased by 233%, product advisory usage (Warmtewijzer) grew by 110%, and overall conversions rose by 150%.
