The Radio Teleswitch Service (RTS) is Being Turned Off: Here’s What You Need to Know

The Radio Teleswitch Service (RTS) is a radio signal system that controls 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.

However, as of 30th June 2025 the RTS will be permanently switched off. Ofgem, the energy regulator for Great Britain, requires energy suppliers to replace all RTS meters before the service ends.

What Does This Mean for You?

If you have an RTS meter, don’t worry — you can upgrade to a smart meter. Smart meters are the only technical replacement for RTS meters because they can be programmed to deliver the same service. If your supplier contacts you, act now.

How to Tell if You Have an RTS Meter

If you’re unsure whether you have an RTS meter, here are some things to look out for:

There may be a separate switch box near your meter with a “Radio Teleswitch” label.
Your property uses electric heating or storage heaters.
There is no gas supply to your property (common in rural areas and high-rise flats).
You receive cheaper energy at different times of day, with tariffs such as Economy 7, Economy 10, or Total Heat Total Control.

If you’re still not sure, you can contact your electricity supplier and they can confirm whether you have an RTS meter.

What Happens if I Don’t Upgrade to a Smart Meter?

If you don’t upgrade, your heating and/or hot water could be impacted. You may experience issues like heating running at the wrong time or being stuck on constantly. Without a working meter, your supplier won’t be able to track your energy usage during peak and off-peak times, potentially leading to higher electricity bills. A smart meter will ensure you continue to receive a similar service to the one you’ve been used to with your RTS meter. If your supplier contacts you to arrange the upgrade make sure you get in touch.
