What is Technical Assurance of Metering Systems?

Technical Assurance of Metering is designed to monitor compliance with metering requirements set out in the BSC and its subsidiary documents. It consists of a combination of sampled and targeted visits to sites with Half Hourly Metering Systems registered in SVA and CVA.

The size and scope of the sample is set by the Performance Assurance Board (PAB) within the Risk Operating Plan (ROP).
