Support from energy suppliers during the RTS switch off

News
Publication date

The phase out of the Radio Teleswitch signal started on 30 June 2025. Energy suppliers are sharing insights and working together with government and us through a managed and sequenced process.

Energy suppliers will begin phasing out groups of RTS meters. Everyone who has an RTS meter will not be switched off at the same time. This approach will mean that energy suppliers are able to manage and fix any problems that may come up during this process.

Replaced meters

Energy suppliers are currently replacing RTS meters with smart meters or alternative metering solutions. The number of meters that have been replaced since the start of this year has gone up. However, there are still just under 300,000 RTS meters that must be replaced during the phase out period.

What energy suppliers must do

Energy suppliers must treat all households and businesses fairly. This includes knowing who needs support and extra help.

As part of the phased switch off energy suppliers should also:

  • give you clear, accessible and timely information that should include details about the Radio Teleswitch phase-out
  • keep a high standard of customer service
  • offer an enquiry service from 1 August 2025 for households including those where there is someone living there who needs extra help
  • prepare for emergencies for example if there is a power cut
  • move people from a Radio Teleswitch meter to a smart meter onto a suitable tariff that reflects their usage patterns

Next steps

If you have an RTS meter your energy supplier should have contacted you to arrange an appointment to upgrade your electricity meter. This should be done as soon as possible to avoid losing heating or hot water during the phase out.

Energy suppliers must follow the rules in their licence as part of the phase-out process. If you are not happy with the support your energy supplier is giving you to replace your Radio Teleswitch meter you can complain about your energy supplier.
