What Businesses Need to Know About the RTS Metering Switch-Off

The UK’s RTS metering service is being permanently switched off on 30th June 2025, and businesses still relying on these meters must act now to avoid disruptions and ensure a seamless transition to modern metering systems.

What is RTS Metering?

Introduced in the 1980s, RTS meters were designed to support time-of-use tariffs such as Economy 7 and Economy 10. These meters utilize long-wave radio signals to automatically switch between peak and off-peak times, allowing businesses to manage flexible load demands effectively.

Why This Matters for Your Business

For those still operating on RTS technology, the upcoming switch-off could lead to significant issues. After June 30th, RTS meters will no longer function as intended, which may result in:

• Incorrect or unpredictable billing
• Loss of off-peak rates
• Operational disruptions, particularly for businesses dependent on night-time or off-peak energy for critical processes like heating, cooling, or manufacturing

What You Need to Do

With just over a month remaining, now is the time to act:

1. Identify RTS Meters Onsite: Check your metering equipment for an RTS label or a separate switch box. If you’re uncertain, consult your energy advisor for guidance.
2. Contact Your Energy Supplier: Suppliers are responsible for replacing RTS meters, typically with smart meters. With over 600,000 RTS meters still in use, securing your upgrade early will help you avoid disruptions.
3. Plan for Installation: Depending on your operational setup, some installations may require coordination with your operations or energy management teams. Planning early ensures minimal impact.

Looking Ahead

The RTS switch-off is part of a broader movement towards smarter, more efficient energy systems. Modern meters provide real-time usage data, remote readings, more accurate billing, and enhanced control over energy management.

Transitioning to smart meters not only ensures compliance but also positions your business to make more informed energy decisions long-term.
