What is the Radio Teleswitch Service (RTS)?

Introduced in the 1980s, The Radio Teleswitch Service (RTS) uses a radio signal to tell some electricity meters when to switch between peak and off-peak rates.

RTS was also used for some traditional multi-rate meters to support customers who use electricity for their heating and hot water, including electric storage systems, panel heaters or immersion heaters in water tanks – some of which typically charge up overnight.

As RTS is now reaching the end of its natural operational life, the equipment that produces the radio signal can’t be adequately maintained anymore.

When will the Radio Teleswitch Service be shut down?

The RTS system will be discontinued on 30 June 2025 across the Energy Industry. After this date, meters that use the RTS may lose critical functionalities. For example, depending on your meter type, off-peak timing might cease to operate, potentially resulting in the loss of heating and hot water services.
 
The impact of these lost functions will be felt by all non-domestic customers with an RTS meter, irrespective of their energy provider. The 2025 deadline applies to all electricity suppliers, and we are proactively reaching out to affected customers to provide them with a meter upgrade before the RTS service concludes on 30 June 2025.

How will I know if I have an RTS meter?

If you're uncertain about having an RTS meter, keep an eye out for these signs:

  • Look for a separate switch box near your meter labelled with "Radio Teleswitch"
  • If your property is heated using electricity or storage heaters
  • In areas without a gas supply (including rural homes or high-rise flats)
  • If you benefit from discounted electricity rates at various times of the day, possibly on Economy 7, Economy 10, or Total Heat Total Control tariffs.

If you're still unsure about having an RTS meter, please contact us.

How will the RTS Switch off affect me?

If you don't arrange to have your RTS meter exchanged before your service is disconnected, your meter may stop functioning properly and become inoperable. 

This means your meter won't be able to switch between peak and off-peak rates, resulting in your hot water not working as expected. It could also lead to your heating being on or off at all times. This could impact your energy bills and the amount you pay for your energy.

To arrange a meter exchange, please contact us.

What alternatives are available to me?

Automatic meter reading (AMR) and Smart meters offer a diverse array of advantages for your business. By sending your energy data directly to us, the hassle of manual meter readings is removed, allowing your valuable resources to be redirected to other areas of your business. With precise energy consumption readings, you can avoid the uncertainties of estimated billing, ensuring that you are only billed for the energy you actually use.
