Smart metering is part of Critical's DNA. We have the credentials, the standards expertise, and the engineering depth to prove it.
The smart meter rollout is no longer a future ambition — it's an operational reality reshaping how utilities manage infrastructure, engage customers, and extract value from data. But the complexity behind it is significant. Next-generation metering systems span embedded firmware, communications protocols, data management platforms, and certification requirements that demand genuine expertise to navigate.
Critical Software has been at the center of this transformation for years. From meter hardware and communications devices to enterprise-scale data platforms, we support clients across the full metering stack — in electricity, gas, green gas, and water sectors.
RECOGNIZED EXPERTISE
Our commitment to excellence in this space has been consistently recognized. Critical Software has received the Smart Data Communications Company (DCC) Partnership Award for five consecutive years — reflecting our role as the market reference for the UK SMETS industry, where we provide comprehensive expertise, development, support, and tooling, and operate the Smart Meter Device Assurance (SMDA) certification lab.
We have also been selected as a technology partner for the DLMS User Association (DLMS UA), recognized for our deep expertise in DLMS and the Great Britain Companion Specification (GBCS), and our contributions to the development of next-generation certification tools.
