Essent's 12-Week Cloud Leap Halves Costs and Boosts Agent Morale

'S-HERTOGENBOSCH, NL – April 22, 2026 – Essent, the Netherlands' largest energy supplier, has successfully executed a sweeping transformation of its contact centre operations, migrating over 1,000 agents to a modern cloud platform in under 12 weeks. The ambitious project, delivered in partnership with customer experience specialists Sabio Group, has yielded dramatic results: a 50% reduction in technology costs, a 36% surge in agent satisfaction, and a complete elimination of the critical system outages that previously plagued the utility provider.

Serving 2.5 million customers, Essent was facing a strategic crisis. Its aging on-premise infrastructure had become a significant liability, incurring massive maintenance expenses and blocking the path to modern, AI-driven customer service. The migration represents a critical pivot, moving the energy giant from a position of technical debt to one of technological leadership, all while ensuring zero disruption to its millions of residential and business customers.

Escaping the Legacy Trap

For years, Essent's contact centre was hamstrung by its legacy voice platform, which had reached its end-of-support life. This turned the system into a major operational risk, described by the company as a system “haemorrhaging money on specialist maintenance.” The costs were not just financial. The outdated technology created a formidable “innovation bottleneck,” making it nearly impossible to implement modern routing logic, integrate automation, or deploy the AI-powered tools that today’s customers expect.

This technological deficit had a profound human cost. Frontline agents, the daily voice of the company, were forced to navigate a disjointed and frustrating digital environment. “Our agents were constantly working with different screens — multiple chat instances open at once, multiple agent desktop instances. It was messy, and in some cases, quite stressful,” explained Michiel Kouijzer, SAFe Product Manager for Customer Interaction, Omnichannel and Digital Transformation at Essent. This multi-screen juggling act was a source of daily friction, hindering efficiency and directly impacting employee morale.

Industry analysis confirms that such legacy systems frequently lead to higher operational risks, spiraling technical debt from years of custom workarounds, and significant security vulnerabilities. For Essent, the end-of-life deadline for its old platform served as a powerful catalyst for change, forcing a strategic decision to leapfrog directly to a flexible, scalable cloud infrastructure.

A High-Stakes Migration in Record Time

Executing a full-scale migration for over 1,000 agents in a mission-critical environment is a monumental task, fraught with risk. A service interruption could impact millions of households. Rather than attempting a perilous 'big bang' cutover, Sabio Group engineered a meticulous phased migration strategy. The process began with Essent's SME (small and medium-sized enterprise) segment, creating a real-world validation environment to test technical readiness and build agent confidence before scaling the solution across the entire operation.

This calculated approach proved invaluable. The voice migration was completed in less than 12 weeks, a rapid timeline driven by the hard deadline of the legacy supplier's contract termination. Six months later, the live chat system was migrated. This phase was deliberately executed during the peak winter demand season—the most challenging time of year for an energy provider. The transition was so seamless it was invisible to customers; not only did the live chat Net Promoter Score (NPS) hold steady, it actually improved during the migration period.

The project’s success challenged internal skepticism. “A lot of colleagues were saying I was mad for even suggesting this approach,” Kouijzer admitted. “It kind of feels like a victory on a personal level that it did work out. You just have to be a little ambitious — and have the right expert partner who can make it work.”

Sabio's role extended far beyond simple implementation. Technical consultants were embedded on-site at Essent's headquarters, integrating directly into the company’s agile sprint teams. This deep collaboration was essential for managing the complex coordination required across telecommunications carriers, the network infrastructure of parent company E.ON, and critical CRM integrations.

The Human and Financial Dividends

The project's outcomes have been unambiguous and impactful. The most immediate benefit was a 50% reduction in contact centre technology costs. This dramatic saving stems from the elimination of expensive on-premise hardware, costly software licenses, and the exorbitant fees for specialist maintenance on an unsupported platform. By moving to a cloud-based subscription model, Essent has shifted its spending from reactive maintenance to strategic investment.

Equally important has been the transformation of the employee experience. The agent workplace NPS, a key measure of employee satisfaction, surged by 36%, rising from +19 to +26. This significant improvement is a direct result of replacing the stressful, multi-screen chaos with a unified agent workspace. For the first time, agents have voice, chat, and all relevant customer data consolidated into a single, intuitive interface. This has fundamentally changed their daily workflow, reducing stress and empowering them to focus on customer needs rather than fighting their tools.

Furthermore, the operational stability of the new environment is a stark contrast to the past. Since the go-live, Essent has recorded zero critical incidents. The periodic outages that once disrupted service and frustrated both customers and agents are now a thing of the past, underscoring the resilience and reliability of the new cloud foundation.

Building the Foundation for an AI-Powered Future

This migration was more than just a remedy for an aging system; it was a strategic move to future-proof Essent's customer interactions. “This project showcases Sabio's unique position in the contact centre technology landscape,” noted Wouter Bakker, Country Manager for Sabio Group Benelux. “We’re not just moving Essent to the cloud — we’re establishing a foundation for continuous improvement in their customer experience delivery.”

With a stable and flexible cloud infrastructure now firmly in place, Essent is turning its attention to a new frontier of innovation. The company is actively exploring capabilities that were previously impossible, including AI-powered call summarization to reduce agent after-call work, sophisticated agentic self-service to handle complex customer queries autonomously, and next-generation workforce optimisation to enhance operational efficiency.

By successfully navigating this complex technological shift, Essent has not only solved its immediate operational challenges but has also positioned itself at the forefront of customer service innovation in the European energy sector. The new foundation enables the company to adapt quickly to changing customer expectations and leverage the full potential of artificial intelligence to create a more efficient, intelligent, and responsive customer experience.
