The UK’s energy infrastructure is undergoing significant changes, and one of the most impactful is the planned RTS Meter Switch Off on 30 June 2025. This development has far-reaching consequences, especially for households and businesses relying on RTS (Radio Teleswitch Service) meters for their energy consumption.
Understanding the Radio Teleswitch Service (RTS)
Introduced in the 1980s, the RTS allowed energy suppliers to remotely control electricity tariffs and manage load distribution by sending signals over the long-wave frequency of BBC Radio 4. This system was particularly beneficial for customers on time-of-use tariffs like Economy 7 and Economy 10, enabling them to take advantage of cheaper electricity rates during off-peak hours.
However, the technology underpinning RTS is now outdated. The infrastructure, including the Droitwich transmitting station, is ageing, and the BBC has indicated that once the existing equipment fails, it will not be replaced.

Impact on Energy Meters
Approximately 530,000 households in the UK still use RTS meters. If you’re among them, here’s what the RTS meter switch-off 2025 means for you:
- Loss of Automated Tariff Switching: Without RTS, your meter won’t automatically switch between peak and off-peak rates, potentially leading to higher electricity bills.
- Heating and Hot Water Disruptions: Many RTS meters control electric heating and hot water systems. After the switch-off, these systems may not function as intended, causing discomfort and inconvenience.
- Billing Issues: Inaccurate meter readings could result in estimated bills, making it harder to manage energy expenses effectively.
Transitioning to Smart Meters
To mitigate these issues, energy suppliers are urging customers to upgrade to smart meters. These modern devices offer several advantages:
- Real-Time Monitoring: Track your energy consumption in real-time, helping you make informed decisions to reduce usage and costs.
- Automatic Readings: Say goodbye to manual meter readings. Smart meters send data directly to your supplier, ensuring accurate billing.
- Flexible Tariffs: Access to a wider range of tariffs, including time-of-use plans that can help you save money.
Energy suppliers like Octopus Energy, E.ON Next, and EDF are actively contacting customers to schedule smart meter installations. However, with a large number of households needing upgrades, appointment availability may become limited as the deadline approaches.

RTS Meter Switch Off’s Broader Implications: Alarms and Security Systems
The RTS meter switch-off 2025 is part of a broader move away from analogue systems. Notably, BT has announced the closure of its Redcare alarm signalling service by 1 August 2025. This service has been integral in connecting fire and intruder alarms to monitoring centres. Its discontinuation means:
- Security Risks: Alarms relying on Redcare may cease to function, leaving properties vulnerable.
- Insurance Concerns: Many insurance policies require active alarm systems. A non-functional alarm could affect your coverage.
Businesses and homeowners should consult with their alarm service providers to explore alternative solutions that comply with the upcoming digital infrastructure. You can also explore BT’s Redcare FAQs for further details.
Action Step
- Check Your Meter: If you’re unsure whether you have an RTS meter, look for a separate switch box labelled “Radio Teleswitch” near your electricity meter. Alternatively, contact your energy supplier for confirmation.
- Schedule a Smart Meter Installation: Reach out to your supplier to arrange for a smart meter upgrade well before the June 2025 deadline.
- Review Other Systems: Assess whether other services, such as alarm systems, rely on analogue networks and plan for necessary upgrades.
- Stay Informed: Keep abreast of updates from your energy supplier and service providers to ensure a smooth transition.

Conclusion
The RTS meter switch-off 2025 marks a significant shift in the UK’s energy and communication landscape. While it presents challenges, it also offers an opportunity to embrace more efficient and reliable technologies. By taking proactive steps now, you can ensure continuity in your energy services and maintain the safety and security of your property.
