Do you have an RTS electric meter?

Do you use electric heating or storage heaters?

If you do, you may have a Radio Teleswitch Service (RTS) electricity meter.

You should have been told by your electricity supplier that you need to have your radio teleswitch (RTS) or dynamically teleswitched (DTS) electricity meter replaced.

This is because the radio frequency it uses to switch between peak and off-peak rates is being switched off on 30 June 2025.

This means that after 30 June 2025, your heating and hot water would stop working if you still have the RTS or DTS electricity meter.

But don’t worry, as your electricity supplier should have contacted you to get it replaced ahead of the date.

 

Check if you need to replace your meter

You might not know if you have a radio teleswitch (RTS) or dynamically teleswitched (DTS) meter.

You might have an RTS meter if you:

  • Use electric heating to heat your home. 
  • Have a tariff where the price of electricity changes at different times of day. 
  • Have a separate box near your electricity meter with the words ‘radio teleswitch’ or ‘radio telemeter’.
  • Have two codes on your electricity bill that start with the letter S. These are ‘supply numbers’ or ‘S numbers’.
  • Live in a house with no gas connection. 

 

If you’re not sure if you have an RTS or DTS meter

Contact your electricity supplier to check if your meter needs replacing.

 

I’ve got an RTS meter. What do I do?

Get in touch with your electricity supplier as soon as possible and arrange to replace the meter. Your supplier must replace your meter to make sure there’s no disruption to your electricity supply. 

Your supplier should upgrade you to a smart meter for free. If you can’t have a smart meter, your supplier still has to replace your RTS meter with a suitable alternative.

You don’t pay anything to change your meter. If someone contacts you and says you have to pay to change your meter, this is a scam.
