If you've recently seen a smart meter warning from British Gas, either online or via the British Gas app, you're not alone. Thousands of customers across the UK are reporting issues ranging from technical glitches to outdated meter systems—particularly affecting users with RTS (Radio Teleswitch Service) meters.
In this blog post, we'll break down what's going on, who’s affected, and what you need to do if you're seeing warnings or experiencing problems with your smart meter.
🔔 What Does the British Gas Smart Meter Warning Mean?
British Gas smart meters typically display warnings when:
-
The device is unable to connect to the network.
-
There is low signal strength, impacting meter readings.
-
Your meter is an RTS meter that's due to be replaced.
-
There is an outage or service disruption affecting your area.
-
There’s a fault with the in-home display (IHD) or the meter itself.
If you received a warning through the British Gas app or your online account, it's likely related to one of these ongoing national issues.
📅 British Gas Smart Meter Problems Today—April 2025 Update
As of today, there are widespread reports of issues specifically linked to:
-
RTS meters, which rely on a radio signal to switch between tariffs (such as Economy 7). This service is being phased out across the UK, leading to problems for users still dependent on it.
-
Smart meter connectivity issues, where meters are not sending usage data back to British Gas, resulting in estimated bills or billing delays.
-
Glitches in the British Gas app cause users to see error messages or receive false warnings about energy usage or system faults.
British Gas has acknowledged some of these issues on their official channels and is rolling out support and replacements, but delays are common.
🔧 What Is the Radio Teleswitch Service (RTS) and Why Is It an Issue?
The Radio Teleswitch Service (RTS) was developed in the 1980s to allow energy providers to remotely control meters via longwave radio signals—primarily for things like Economy 7 or time-of-use tariffs.
But in 2025, this system is considered outdated, and the national RTS infrastructure is set to shut down permanently. That means
-
If you're still using an RTS meter, it needs to be upgraded to a modern smart meter.
-
Energy providers, including British Gas, are urging customers to book meter replacement appointments before the signal is switched off.
⚠️ What Should You Do If You Get a Warning?
If you receive a smart meter warning from British Gas, here’s what to do:
-
Check the app or online account to see what the warning says specifically.
-
Restart your In-Home Display (IHD)—sometimes it's just a connection issue.
-
Contact British Gas support, especially if you're still on an RTS meter.
-
If prompted, book a smart meter upgrade appointment—especially urgent for Economy 7 or dual-rate customers.
📝 Final Thoughts
Smart meters are supposed to make your energy usage simpler, but recent issues have left many British Gas customers frustrated—especially those with RTS meters.
