Do you have an RTS meter at home? Now is the time to act!

The signal that controls Radio Teleswitch Service (RTS) meters (also known as Dynamic Teleswitched Service (DTS)) is being switched off from 30th June 2025.
If you have a Radio Teleswitch Service (RTS) meter at home you need to act now. Otherwise your heating and hot water might stay permanently on or permanently off. You might also be charged the wrong price for your electricity.
How do I know if I have an RTS meter in my home?
You might have a Radio Teleswitch (RTS) or Dynamically Teleswitched (DTS) meter if:
- your home has a separate switch box near your meter with a Radio Teleswitch label on it
- your home is heated using electricity or storage heaters (sometimes called panel heaters)
- there is no gas supply to your area, including households in rural areas and high-rise flats
- you get cheaper energy at different times of day, for example, you might be on an Economy 7, Economy 10, or Total Heat Total Control Tariff
You might find a teleswitch in the same box as your meter or in a separate box. If it's in a separate box it will usually be black. If you’re not sure, talk to your electricity provider today.

What should I do if I have an RTS meter, or I’m not sure if I do?
Contact your electricity supplier. They will be able to check with you whether you have an RTS meter. If you do, they’ll arrange to replace your meter free of charge.
