Replacing your Radio Teleswitch electricity meter

We wanted to let you know about the Radio Teleswitch Service (RTS) switch off which will affect customers with RTS electricity meters.

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.

All electricity suppliers should replace all RTS meters before the Radio Teleswitch Service technology ends.

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

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

You can find more information about the RTS switch off, including how to contact your supplier by visiting Ofgem's website.
