From 30th June 2025, the signal that controls RTS electricity meters is being switched off.
This means if you have an RTS meter, your heating and hot water may stop working as normal.

What is the radio teleswitch service (RTS)?

RTS uses a radio signal to tell some older electricity meters when to switch between peak and off-peak rates. It’s coming to an end because the service has reached the end of its operational life. If you have an RTS electricity meter it will need to be replaced.

How can I tell whether I have an RTS meter?

The best way is to contact your supplier. Suppliers have access to the most up to date information about what type of meter you have. Some things you may look at that might give them an indication that you have an RTS meter are:

  • The property is heated using electricity or storage heaters.
  • You get cheaper energy at different times of day (usually overnight). Your tariff might be: Economy 7, Economy 10 or Total Heat Total Control.
  • There is no gas supply to the property.
  • There may be a separate switch box near the meter with a Radio Teleswitch (RTS) label on it.

If you think you may have an RTS meter, you should contact your electricity supplier and they will arrange for it to be changed.

IF YOUR ENERGY SUPPLIER CONTACTS YOU, TAKE ACTION TO BOOK YOUR INSTALLATION.
