From 30 June 2025, the Radio Teleswitch Service (RTS) will start to phase out as it is reaching the end of its operational life. RTS is also known as Dynamic Teleswitch Service (DTS). The switch-off will affect energy customers who have an RTS meter in their home, and may mean their heating and hot water supply stops functioning as normal.

There will not be a mass switch off of the RTS national signal on 30 June 2025. From this date, a phase out will begin of the RTS functionality for small groups of meters at a time. Customers will be informed directly.
