Radio Teleswitch Service switch-off – what you need to know

07/04/2025

From 30 June, the Radio Teleswitch Service (RTS) is switching off. If you have an electricity meter that is managed by this system, this change could affect your home electricity and hot water supply. Your energy supplier should have contacted you about arranging an upgrade, if you think you might be affected, you should contact your energy supplier.

 

What is an RTS meter?

Some homes have an older electricity meter called an RTS meter. These meters use a radio signal to switch meters between peak and off-peak rates. The radio signal that controls these meters is going to be switched off because it has reached the end of its operational life.

How to know if you have an RTS meter

  • You may have an RTS 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
  • 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

What happens if you have an RTS meter  

If you are affected, your energy supplier should contact you to arrange an upgrade of your meter. If you’re not sure if you’re affected, get in touch with your electricity provider as soon as possible.

What happens if your meter isn’t replaced?

If your RTS meter is not replaced before the switch-off, it could cost you significantly more to heat your home and use hot water, or you may be left with no electricity.
