A quick checklist for fixing smart meter problems

Is it your smart meter or just the in-home display (IHD)?

In many cases, the issue is not the smart meter itself but the IHD and many bill-payers get confused between the two. Below, on the left is an IHD, whereas on the right is an electricity smart meter. An IHD is a small display kept indoors that shows your energy usage, while a smart meter refers to the electricity or gas meter that records and sends readings to your supplier. If your IHD is blank or not updating, your meter may still be working and sending readings correctly.

Common smart meter problems

Smart meter issues are usually related to communication rather than the meter itself. In some cases, the connection to your supplier is interrupted. In others, older meters, especially SMETS1, may lose functionality after switching supplier and require manual readings.

These issues can result in estimated bills if readings are not being received automatically.

Why your smart meter may lose connection

Smart meters rely on network connectivity to send readings. If that connection is interrupted, your meter may stop communicating.

This can happen due to:

In many cases, the issue resolves itself once the connection is restored.

Checking for power cuts and network issues

Before assuming a fault, check if there is a power cut in your area. A power outage will stop both your smart meter and display from working. Smart meters may also rely on mobile network signals depending on meter type and install. If there are local network issues, your meter may temporarily stop sending readings. Once power or connectivity is restored, the meter should reconnect automatically.

What to do if your smart meter stops sending readings

If your smart meter is not sending readings, you may need to submit them manually to keep your bills accurate. Fuse Energy allows you to submit readings easily through the app, including uploading a photo for convenience. This ensures your billing reflects your actual usage.

Tariff eligibility

Some tariffs require a fully connected smart meter. EV tariffs and time-of-use tariffs rely on real-time usage data, so your meter must be online to access them. If your meter isn’t connected, you may need to resolve the issue or upgrade before switching to these tariffs.
