Question to the Department for Business, Energy and Industrial Strategy:

To ask the Secretary of State for Business, Energy and Industrial Strategy, how many meters a DCC communications hub will need to have (a) tested and (b) operating on its communication system before a decision can be made on the reliability of that system.

This is a matter for individual energy suppliers to decide. Their assessment of the reliability of their SMETS2 offering will need to take account of, amongst other things, their own progress in integrating their meters with the DCC system and the testing of their own back office systems.
