Don’t Get Left Behind
In June 2025, the UK will mark a major shift in energy infrastructure as the Radio Teleswitching (RTS) system is officially retired. This is more than just a technical update—if your business still relies on an RTS meter, it’s time to take action.
Once the signal is switched off, these meters will no longer be able to switch between peak and off-peak rates automatically. That could disrupt your tariff schedules, affect billing accuracy, and ultimately increase your energy costs if not addressed in time.
At Black Sheep Utilities, we’re here to make the transition seamless. Instead of navigating this change alone or chasing suppliers, let us guide you through what it means—and how to upgrade with minimal disruption.
What Are RTS Meters?
RTS meters have been used for decades to support multi-rate tariffs such as Economy 7 or Economy 10. These meters receive radio signals to control when certain appliances (like storage heaters) switch on or off, allowing users to benefit from cheaper off-peak electricity rates.
While once cutting-edge, the technology behind RTS meters is now outdated and difficult to maintain. The network powering these signals is being turned off, and with it, RTS meters will stop functioning as intended.
Why Is RTS Being Switched Off?
The RTS system simply doesn’t meet the needs of today’s smarter, more sustainable energy market. It’s being retired in favour of modern, connected solutions—namely, smart meters.
Rather than spend hours researching metering options or chasing suppliers, let Black Sheep Utilities take the pressure off. We’re already supporting clients through this change, ensuring they avoid disruptions and take full advantage of what comes next.
