Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what plans he has to modernise dynamically teleswitched meters; and whether he has made an assessment of the potential impact of changes to those meters on energy price charging.

The smart metering system in Great Britain has been designed to enable a range of flexible and dynamic tariffs that reward energy consumers for using electricity away from peak times, or when there is excess clean electricity available.

Suppliers are in the process of contacting consumers using the Radio Teleswitching Service (RTS) to encourage them to upgrade to smart meters. This upgrade will ensure continued access to ‘time of use’ tariffs, including Economy 7. All smart meters can support tariffs which charge different prices throughout the day and night.

The RTS will remain operational until at least 31st March 2024.
