Overview

• Selected areas experienced the first phase of Radio Teleswitch Service deactivations on June 30 under the managed transition plan.
• Approximately 315,000 households still use RTS meters and risk losing automated hot water and heating schedules without new smart devices.
• Ofgem and the Department for Energy Security and Net Zero require suppliers to notify affected customers and activate contingency arrangements ahead of each deactivation.
• Major suppliers including British Gas, E.ON Next, Octopus Energy and Ovo Energy are prioritising RTS meter replacements despite ongoing smart meter appointment backlogs.
• Rural and off-gas grid homes face heightened vulnerability as limited appointment availability could leave them on peak-only tariffs.
