Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, which organisation (a) designed and (b) commissioned the second generation of smart meter mesh networks.

The Data Communications Company (DCC) was responsible for leading the design, build test and implementation of the overall end-to-end solution for second generation meters. Mesh based solutions were chosen by Telefonica (now Virgin Media O2) and Arqiva who are service providers contracted to DCC to supplement their primary wide area network technologies to meet their coverage obligations.

The mesh technology is installed and commissioned by energy suppliers (as part of a smart meter installation) as directed by the Data and Communications Company’s Wide Area Network coverage checker.
