Compliant, interoperable smart meters aligned with evolving SMETS standards
Reducing smart meter testing time for a leading UK energy supplier
Challenge
A major UK energy company was held back by a manual, smart-meter testing tool that had month-long test cycles and heavy reliance on a small group of legacy experts.
Approach
We developed an automated smart meter testing platform that enables testers to design and execute large-scale tests on real devices in a controlled lab environment.
Results
The new automated platform is already cutting testing cycles, enabling reducing risk, and future-proofing smart meter interoperability.
The challenge: Smart meter testing causing delays and inefficiencies
The energy provider’s smart metering business unit relied on a largely manual testing tool developed as a proof of concept more than seven years ago. This legacy system allowed only one test set at a time, meaning a single testing cycle could take over a month to complete. This was unsustainable given the fast-moving landscape of new devices, firmware versions and interoperability requirements.
With thousands of hardware and software combinations to validate, the approach created mounting backlogs and depended heavily on a small pool of experts to maintain ageing tools.

Our approach: A compliant smart meter testing platform
Resillion built a new automated smart-meter testing platform tailored to the energy provider’s environment. Designed from scratch with scalability in mind, the platform ensures full compliance. It automates most testing steps and supports electricity meters, gas meters, comms hubs, in-home displays (IHD) and Prepayment Meter Interface Devices (PPMID) in a controlled lab environment.
Multiple test cycles can now run in parallel, cutting down testing time and resource needs. The modular, cloud-ready architecture is easy to update and adapt for other SMETS2-based (Smart Meter Equipment Technical Specifications) utilities.
What we’ve built isn’t just faster - it’s smarter, scalable and ready for what’s next. Testing has been streamlined and automated, and the burden on the team has dropped massively.
What we delivered
Results: Faster testing and future-ready smart meter interoperability
With 50% of testing already automated, cycles have accelerated and can now run continuously, without heavy manual intervention. This makes it easier to ensure devices and firmware work seamlessly together, reducing risk and unlocking full interoperability across the smart meter estate.
Automation is boosting speed and productivity while keeping engineers firmly in the loop, focused on defect analysis and collaboration with manufacturers. Reduced reliance on legacy expertise has created a more resilient testing process, while the platform’s flexible architecture ensures it can adapt easily to new devices, firmware and evolving SMETS standards, future-proofing smart meter testing at scale.
