Accelerating smart energy product launches for UK energy provider

Challenge

The energy provider needed complete confidence that their new smart energy products would perform reliably.

Approach

We engineered a full suite of test assets to validate every part of the smart-energy product stack.

Results

The organisation launched dynamic pricing features to 300,000 users within weeks, supported by reusable test frameworks.

The challenge: Real-world readiness for smart energy innovation

The energy provider was launching a new generation of smart energy products designed to help customers save money while supporting a greener, more flexible energy grid.

Two flagship services led the way: automated EV charging at the cheapest and greenest times, and dynamic pricing features such as half-price weekends to encourage smarter energy use.

But delivering these innovations at scale is complex. Each service relies on a web of mobile apps, pricing engines, third-party platforms and real-world hardware in customers’ homes.

To launch with confidence, the provider needed certainty that everything would work seamlessly in the real world, not just in controlled test environments.

Our approach: Testing a complex smart energy ecosystem

We worked closely with product and engineering teams to test the full ecosystem, from app interfaces and pricing logic to live EV chargers and home-energy devices. Our approach used real-world scenarios to model how customers actually interact with these products under different tariff and demand conditions.

We validated end-to-end journeys to ensure pricing rules were applied correctly, EV charging kicked in at the right times, and user interfaces displayed accurate, timely information. Automated frameworks and repeatable test assets were created to reduce manual effort and support rapid product iteration.
