To adapt to the constantly changing industry, a leading energy company in the UK wanted to differentiate itself by transforming its customer experience and offering exciting new features and functionality on the cloud. The client collaborated with AWS, which in turn engaged EPAM in the solution delivery due to our capabilities in driving digital transformation and amplifying AWS industry expertise.


Deliver a customer-centric transformation on AWS cloud

The evolving landscape of enhanced customer expectations, emerging competitors, regulatory demands, smart metering adoption and sustainability goals is driving significant change in the energy sector. One of the most prominent energy companies in the UK was fiercely competing with digital-first energy startups, posing a threat to its market share.

For the company, it was crucial to undergo a strategic business change. This involved implementing advanced technologies to diversify payment channels, establishing a streamlined customer service framework to enhance agent touchpoints and adopting agile processes to ensure service flexibility. Additionally, incorporating predictive analytics and leveraging data-driven insights was instrumental in refining the top-up process for energy procurement. This comprehensive business transformation was essential to not only meet current customer expectations but also to stay ahead in a rapidly evolving market.

The company forged a strategic partnership with AWS, as well as a UK-based energy and utilities software-as-a-service (SaaS) billing and market connectivity solutions provider and a leader in customer relationship management (CRM) platforms. AWS pulled in EPAM, the global leader in digital engineering and software development services, to deliver comprehensive energy and utilities consulting and engineering services for enhanced customer experience.

Together, the team is transforming the experience it provides to its customer with enhanced functionality and features that leverage the power of the cloud.
