Important changes to RTS electricity supply meters.

If you have an RTS (radio tele-switch) electricity meter, your energy supply may be affected by forthcoming changes to the system. From June 30, 2025, the technology that supports RTS will switch off and these meters may no longer work properly or know when to swap between peak and off-peak rates. This could mean that your heating and hot water supply stops functioning as normal.

 

Your electricity supplier owns and maintains your meter. They will get in touch to arrange an upgrade to a smart meter before this deadline. Please check your email and post to ensure you don’t miss any important information.

 

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

 

You may have an RTS meter if:

 

• Your home has a separate switch box near your meter with a Radio Tele-switch label on it.
• Your home is heated using electricity or storage heaters.
• 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.

 

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