Old electricity meters that will be switched off from June 2025 across the UK.
The Radio Teleswitch Service (RTS) uses a radio signal to tell some older electricity meters when to switch between peak and off-peak rates. There are approximately 650,000 RTS meters in homes and businesses in Great Britain.
The 2025 shutdown
RTS is an industry-wide service. All electricity suppliers are contacting impacted consumers to offer them an upgrade before the RTS service ends from 30 June 2025.
