This summer the Radio Teleswitch Service (RTS), also known as Dynamic Teleswitch Service (DTS), will end as it reaches the end of its operational life. This switch-off will affect energy customers with an RTS meter in their home, potentially impacting their heating and hot water supply.

What You Need to Know:

• RTS End Date: 30th June 2025
• Impact: Heating and hot water supply may be affected for those with RTS meters
• Replacement: Ofgem expects energy suppliers to replace all RTS meters with smart meters before the service ends. Smart meters are the only technical replacement for RTS meters and can deliver a similar service.

Action Required:

• Identify Your Meter: If you’re unsure whether you have an RTS meter, look for a separate (often black) switch box near your meter with a radio teleswitch label, or check if your property uses electric storage heaters and has no gas supply. You may get cheaper energy at different times of day. Your tariff might be: Economy 7, Economy 10 or Total Heat Total Control.

If you’re still unsure, contact your supplier.

Contact Your Supplier: If you have an RTS or DTS meter, get in touch with your electricity supplier to arrange for a smart meter upgrade.

If our customers have an RTS meter and do not upgrade, their heating and/or hot water provision in their home will become affected after the 30th June 2025.

What will happen if I still have an RTS meter after 30th June 2025?

Heating and/or hot water may switch itself permanently ‘on’ or ‘off’. Alternatively, it may charge up at random, wrong times of the day. The electricity supplier won’t be able to confirm how much ‘off peak’ electricity has been used, which means electricity usage and costs recorded by suppliers would be impacted.
