Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what discussions his Department has had with Ofgem on potential regulatory enforcement action for companies that do not enable Total Heating Total Control customers to change metering systems.

The smart metering system has been designed to enable a wide range of tariffs, independently of the Radio Teleswitch Service, which Total Heating Total Control tariffs rely on. Energy suppliers are obligated under their licence conditions to taking all reasonable steps to install a smart meter where a meter is fitted for the first time or when an existing meter needs replacing.

The regulator Ofgem is responsible for ensuring energy suppliers comply with their regulatory obligations and take any necessary enforcement action. The Department for Energy Security and Net Zero works closely with Ofgem on monitoring supplier performance.
