The closure of radio teleswitching explained
Issued by Home Energy Scotland
The Radio Teleswitching Service (RTS) is due to end on Monday 30 June 2025.
If your electricity meter uses RTS, it must be replaced. If the meter isn’t replaced, your heating could end up always on, never on, or turning on and off at unsuitable times for you. Luckily, we have a guide on the next steps to take (external link).
What is RTS?
RTS is a system that uses radio signals to control when certain electricity meters switch between peak and off-peak rates. It’s commonly used in homes with electric storage heaters, panel heaters, wet electric heating, and immersion heaters.
What do you need to do?
If you have a RTS meter, your energy supplier should contact you to arrange a smart meter upgrade before the RTS switch-off. If you haven’t heard from them, it’s important that you get in touch as soon as possible to book an appointment.
What happens if your meter isn’t replaced?
Without an upgrade, your heating and hot water may not work properly, and your electricity costs could increase. For more details — including how to check if you have an RTS meter and what to do if your supplier can’t install a smart meter yet — check out our comprehensive guide below.
