Smart Meter Read Hub Project Progress

Aim

This project aims to help trading parties maximise the benefits of smart metering by making it easier for wholesalers and retailers to share smart meter read data efficiently and consistently via a central smart meter read hub.

The project is being delivered in two phases. Phase 1 will see the hub delivered by Spring 2026. In Phase 2, the hub will be connected to the central market operating system, allowing retailers to select and enter meter read(s) directly into CMOS for billing and settlement purposes.

Phase 2 is due to be delivered in Summer 2026 and go live in December 2026 to align with the approval of changes to the market codes and updates to CMOS. Use of the hub will also become mandatory from this point.
