Question to the Department for Energy Security & Net Zero:

To ask His Majesty's Government what assessment they have made, if any, of the number of smart meters which malfunction in the UK.

The Department is working closely with industry and Ofgem to reduce the proportion of smart meters not operating in smart mode. Data on this is included in the statistics the Government publishes every quarter on the progress of the smart metering rollout. These are available at: https://www.gov.uk/government/collections/smart-meters-statistics and at Gov.UK. This shows that over 90% of smart meters are functioning in smart mode and that the proportion of meters operating in ‘traditional’ mode is steadily reducing. Smart meters operating in traditional mode continue to record energy usage accurately but do not send automatic readings to energy suppliers.
