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

To ask the Secretary of State for Business, Energy and Industrial Strategy, what estimate his Department has made of the number of energy smart meters which are operating in dumb mode.

It is estimated there are currently around 400,000 meters being operated by large suppliers in ‘traditional’ mode.

There were more than 8.6 million smart and advanced meters operating in Great Britain, in ‘smart mode’, as of 30 September 2017.

The Data and Communications Company (DCC) will move SMETS1 meters into its national system, starting later this year, so that all consumers can keep their smart services when they switch energy supplier, regardless of which generation of meter they have installed.
