Find out what you need to do before support for Radio Teleswitch Service (RTS) meters switch off in 2025.

The technology that supports RTS electricity meters will switch off from 30 June 2025. Without the technology to tell RTS meters when to swap between peak and off-peak rates, they may no longer work properly, and it may mean that a consumer’s heating and hot water supply stops functioning as normal.

If you have an RTS meter, your electricity supplier will get in touch to arrange an upgrade to a smart meter before this deadline.

They must make sure you have a suitable meter installed, and that your service is not disrupted.

We expect electricity suppliers to replace all RTS meters before the Radio Teleswitch Service technology ends.

Support to upgrade RTS electricity meters

We are working with energy suppliers, distribution network operators, consumer groups and others as part of the RTS Taskforce to support people with an RTS meter. Read more information about the RTS Taskforce.

If you have an RTS meter your electricity supplier will contact you to arrange an appointment to upgrade your electricity meter. You should arrange an upgrade of your meter to avoid losing heating or hot water after 30 June 2025.

Find out if you have an RTS meter

You may have an RTS meter if:

• your home has a separate switch box near your meter with a Radio Teleswitch label on it
• your home is heated using electricity or storage heaters
• there is no gas supply to your area, including households in rural areas and high-rise flats
• you get cheaper energy at different times of day, for example, you might be on an Economy 7, Economy 10, or Total Heat Total Control tariff

Get in touch with your electricity supplier if you’re still not sure which meter is in your home.

If you do not know who your supplier is, follow the steps on our find your energy supplier page.

Upgrading to a smart meter

A smart meter will give you a similar service to your RTS meter. You’ll also get other benefits, including:

• electricity readings submitted automatically
• access to ‘smart meter only’ tariffs
• the ability to monitor your energy usage
• accurate bills based on the electricity you’ve used, not estimates

If you’re not able to upgrade

In some instances, your supplier may not be able to offer you a smart meter at the moment.

If this is the case, they must make sure you have a suitable meter installed, and that your service is not disrupted.

You should contact your supplier to understand the options available to you. 

If you do not want a smart meter

Upgrading to a smart meter is the best option for RTS customers. If you choose not to upgrade:

• your heating and hot water may be left continually on or off
• your electric storage heaters may charge at the wrong time of day, possibly leading to higher bills
• your supplier may be unable confirm your electricity usage during peak or off-peak times, and your electricity costs may be higher than before
• you’ll have a more limited choice of tariffs.

Talk to your supplier for more information.
