A quick checklist for fixing your smart meter

Is it your smart meter or 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 reasons your smart meter isn’t working

Smart meters can stop working for a few reasons. Sometimes the connection between the meter and your supplier is interrupted. In other cases, the issue is simply with the display or signal rather than the meter itself. Older meters, such as SMETS1 or radio teleswitch (RTS) meters, may also experience connectivity issues or limited functionality.

Checking for a power cut

Before assuming your meter is faulty, check if there is a power cut in your area. A loss of power will stop both your smart meter and display from working. Once power is restored, most meters reconnect automatically. If not, restarting your display is often enough to resolve the issue.

What to do if your smart meter stops sending readings

If your smart meter is not communicating, you may need to submit manual readings. This ensures your bills remain accurate while the issue is being resolved. Fuse Energy allows you to submit readings easily through the app, including uploading a photo or as text for convenience.

Tariff eligibility

Some tariffs require a fully connected smart meter. EV tariffs and time-of-use tariffs rely on real-time 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.
