Pivoting towards simplicity
Before E.ON Next adopted Kraken Customer in 2020, their legacy stack was seriously holding them back. Their outdated legacy IT systems were increasing costs and causing issues in customer service. Work was siloed across departments, creating layers of handoffs, poor query ownership, and a customer experience that lagged market expectations.
For customer operations, the challenge wasn’t just about software. Roughly 4,500 people across internal teams and outsourced partners were powering this large and complex operation, and E.ON Next needed to move toward a leaner, more efficient service model.
Offering one joined-up utility operating system that handles meter reads, billing, customer contact, and account management, E.ON Next migrated 5.8M customers successfully onto Kraken Customer between June 2020 and June 2022.
Embracing universal agents
E.ON Next equipped agents with Kraken’s unified data model and intuitive interface, providing greater visibility and less friction when managing customer interactions. Agents no longer have to swivel-chair across disparate tools and pass customers between teams; now, they can complete their tasks within a single Kraken environment.
At the heart of this operational transformation is the ‘universal agent’: team members who can own the customer relationship and handle any query from start to finish. E.ON Next embraced this model as a core strategic differentiator, and supported its introduction with a significant cultural shift.
New tools, new opportunities
E.ON Next has leveraged our Open Kraken architecture to build interoperable applications fit for their scale and complexity:
- An internal management system to improve cross-system workflows
- A proprietary debt management system (DMS) to manage UK-specific collections journeys
- An agentic voice bot that handles inbound calls and actions for meter reads and payments
The service team has adopted Human Assist: AI-powered productivity tools including Magic Ink (a drafting tool for written messages) and Complaints IQ (an intelligent summarization tool to resolve complaints faster).
E.ON Next’s thoughtful roll-out had an impressive impact: 90% of agents use Magic Ink, and over 75% of outbound messages start with an AI-generated draft, boosting response quality and customer satisfaction.
