What is RTS – and why does it matter?
RTS is an old system that sends radio signals to certain electricity meters, helping them switch between peak and off-peak times. This means households can take advantage of cheaper electricity at night or during off-peak hours – often used for things like heating water or running appliances.
Many people rely on RTS without realising it. But from the end of June, this signal will stop – and if you’re still using an RTS meter, your heating and hot water might stop working as they should.
Do I have an RTS meter?
Your energy supplier should have already contacted you if you're affected. But if you're not sure, here are some signs that you might have an RTS meter:
- You have electric storage heaters or heat your home/hot water with electricity.
- You live in a flat or multistorey building and don’t have a gas supply.
- You’re on an off-peak tariff (like Economy 7 or 10).
- You’ve noticed a box or switch near your meter labelled “Radio Teleswitch.”
If any of these sound familiar, or you’re unsure, contact your electricity supplier straight away. They can tell you for certain and arrange a free upgrade if needed.
If you already have a smart meter, you're not affected and don’t need to do anything.
Why is RTS being switched off?
The RTS system is outdated and is being phased out across the UK. Smart meters are now the standard replacement. They do the same job – and more – using newer, more reliable technology.
Smart meters can:
- Automatically switch between peak/off-peak times
- Show you how much energy you're using
- Help you manage your energy costs more easily
What happens if I don’t upgrade?
If you don’t switch to a smart meter before 30 June 2025, your current meter might stop working properly. That could mean:
- You’re charged more for your energy
- Your heating and hot water stop working
- You’re left without the comfort you rely on
What should I do now?
Don’t wait. Here’s what to do if you haven’t switched yet:
- Check if you might be affected – look at the signs above or speak to your supplier.
- Contact your electricity supplier – they’ll explain your options and arrange for a smart meter to be fitted.
- Ask for help if needed – if you’re not sure who your supplier is or need help contacting them, we can point you in the right direction. Click here to contact us.
We know that changes like this can feel stressful, especially if you rely on your current setup. But support is available, and your energy supplier will guide you through the switch.
Make sure you act before 30 June 2025 to avoid any disruption to your heating, hot water, or energy costs.
