The UK government has confirmed that the legacy Radio Teleswitch Service (RTS) — once a cutting-edge solution for managing electricity tariffs and heating systems — will begin a targeted shutdown from June 30, 2025, in a move affecting over 314,000 households. The transition prioritizes consumer protection, especially in Scotland and rural areas, where RTS reliance remains high.
What Is RTS and Why Is It Ending?
RTS, dating back to the 1980s, uses radio signals to switch electricity meters between peak and off-peak tariffs, also controlling heating and hot water. While once vital, RTS has become obsolete in the face of modern smart meter technology. However, slow replacement efforts left many vulnerable households at risk — prompting government intervention.
Phase-Out Timeline and Consumer Impact
Energy Minister Miatta Fahnbulleh announced that the phase-out will begin in regions with the lowest RTS usage to minimize disruption. Advance notice, strict supplier guidelines, and smart meter installations are key features of the plan.
“We’ve stepped in to ensure thousands of vulnerable consumers with RTS meters do not experience any sudden disruption,” Fahnbulleh said.
Key Measures:
- Advance Notification: Suppliers must notify households before signal deactivation.
- Smart Meter Transition: New meters will replicate RTS functions.
- Ofgem Oversight: No area’s signal will be shut off unless all preparation criteria are met.
- Scottish Focus: With 105,000 RTS meters in Scotland, rural protections are a top priority.
What Should Households Do?
Next Steps:
- Book Smart Meter Appointments: When contacted, don’t delay scheduling.
- Check Meter Type: Ask your supplier if you’re affected.
- Stay Informed: Visit Ofgem or your supplier’s site for guidance.
- Report Issues Early: Customer support lines are being reinforced.
Why the Change Matters
Replacing RTS with smart meters ensures:
- Reliable control of heating and hot water
- Access to real-time energy monitoring
- Continued use of off-peak tariffs
- Support for net-zero carbon goals
Ofgem’s Charlotte Friel highlighted the rapid acceleration in installations, noting daily upgrade rates have increased from 1,000 per month to over 1,000 per day thanks to a cross-sector taskforce.
“Customers must be protected at every stage of the phased shutdown,” Friel said.
Broader Energy Reforms on the Horizon
The RTS shutdown is part of wider UK energy market reforms, with future plans expected to:
- Strengthen supplier accountability
- Improve green energy adoption
- Enhance emergency resilience and service quality
A biweekly review system will allow government and Ofgem to track progress, address problems early, and adjust regional support as needed.
Conclusion: A Smart Shift with Consumer Safeguards
While RTS served the UK well for decades, the transition to smart meters marks a modern leap in household energy management. The government’s phased approach, focus on Scotland, and clear safeguards demonstrate a people-first policy in navigating this essential energy upgrade.
