Updates to the Radio Teleswitch Network (RTS)

By the end of June 2025, the Radio Teleswitching Network (RTS) will be switched off. Meters that use this technology rely on radio signals to switch between unit rates at different points during the day.

If your meter uses this technology, it’ll need to be replaced with a new smart meter. But don’t worry – you won’t have to pay for a thing!

Which meters are affected?

If you’re not sure whether you have an RTS meter, there’s a few things you can look out for:

• There may be a separate switch box near your meter with a Radio Teleswitch label on it.
• Your property is heated using electricity or storage heaters, and you get cheaper energy at different times of day.
• Your tariff might be: Economy 7, Economy 10 or Total Heat Total Control.
• There’s no gas supply to your area. This includes households in rural areas and high-rise flats.

Don’t worry, if you’re not sure if your meter needs to be replaced, we’ll be in touch with all affected customers to sort out a meter upgrade.

Will my supply be affected?

If you have a meter that’s connected to the RTS, we’ll need to replace this by June 2025. This is to make sure you don’t lose heating or hot water, and we can continue to bill you correctly for the energy you use.

Can I stay on the same tariff I’m on now?

No, but we’ll offer you a tariff that’s as similar as possible to your current one. We'll get in contact as soon as possible to discuss the replacement tariffs we have on offer for you and will be able to talk you through all your options over the phone.

What happens if I don’t have my meter exchanged?

If we don’t replace your meter - we won’t be able to charge you correctly for your energy. You may also be at risk of your heating or hot water being switched off, or stuck on an incorrect rate.

How can I book my new smart meter upgrade?

Simply text RTS to 88454 to book an appointment and we’ll call you back.

Don’t worry about fitting us into your schedule, your install will take place when it's convenient for you.

Why should I get a smart meter?

As well as providing a new solution for your home’s energy after the RTS is turned off, smart meters are brilliant at making your life easier.
