The UK’s Radio Teleswitch switch-off in 2025 affects thousands of homes using electric heating systems…

📅 RTS Switch-Off Timeline: UK Phase Begins June 2025

The RTS signal will not be switched off all at once. A phased switch-off began on 30 June 2025, starting with small, targeted areas. As of October 2025, over 300,000 RTS meters remain active, and suppliers are prioritising replacements.

🔄 What Happens Next

Your energy supplier should contact you to arrange a smart meter upgrade, which is the only technical replacement for RTS. If you haven’t heard from them, it’s worth calling to book your appointment. Suppliers are required to provide clear, accessible communication and maintain high customer service standards during this transition.

🚨 What If You’re Not Upgraded Yet?

There is no immediate risk of your heating or hot water being disrupted. The government has stepped in to ensure no household faces sudden loss of service. Emergency support services are now available 24/7 from energy suppliers..

🔍 How to Check If You Have an RTS Meter

You may have an RTS meter if: • Your home uses electric heating (e.g. storage heaters, immersion heaters) • You’re on a tariff like Economy 7, Economy 10, or Total Heat Total Control • There’s a Radio Teleswitch box near your meter • You live in a rural area or high-rise flat with no gas supply

💡 Considering an Upgrade

If you’re unhappy with the heat quality, control, or running costs of your current system, now may be the time to switch to a modern electric heating solution that: • Runs off a single meter • Offers full control • Delivers lower bills
