How to fix a smart meter display not working

Finding your smart meter blank, frozen, or showing a warning can be unsettling, leaving you unsure whether your energy is still being measured and whether your bills will be right. Many homeowners ask the same two questions: "Is my smart meter still working?" and "How do I get it back to normal?" The reassuring news is that a smart meter that looks dead is often still recording and sending your readings, and most display problems can be fixed at home in a few minutes.

This guide explains why a smart meter can stop displaying or communicating properly, how to tell a genuine fault from a harmless blank screen, and the steps to get it working again. Fuse Energy aims to make managing your energy straightforward, with clear insight into what you are using. You can get started with Fuse and take control of your energy by clicking here.

Is your smart meter actually broken?

Your smart meter is the device that measures the electricity and gas coming into your home. It is usually fitted where your old meter was: under the stairs, in a hallway cupboard, in a garage, or outside in a meter box. It records your usage and sends those readings to your energy supplier automatically, without anyone needing to call round.

A smart meter has its own small screen, and it is normal for that screen to dim or go blank to save power. A quick press of a button on the meter usually wakes it up. It is also easy to confuse the meter with the small portable screen many households keep on a worktop, the in-home display (IHD), which shows your usage in near real time. The IHD is a convenience, not the meter itself, so a blank IHD does not mean your meter has stopped working.

Does a blank display mean my smart meter is broken?

No, not usually. A smart meter screen often goes to sleep to save power and wakes when you press a button. Even when the screen is blank, the meter normally keeps recording your energy use and sending readings to your supplier. A genuine fault is much rarer than a sleeping screen or a temporary loss of signal.

Why your smart meter might stop working

Several things can make a smart meter look like it has stopped working:

  • Power cut: After a power cut the meter's screen can stay blank or show an error until power is fully restored. The meter is designed to keep your usage data safe in the meantime.
  • Sleeping screen: The display dims or switches off to save energy. This is normal and is fixed with a single button press.
  • Lost connection to your supplier: Smart meters send readings over a national network. If that signal drops, the meter keeps recording but may stop sending readings or show a "no signal" or "no comms" message.
  • "Dumb mode" after a switch: When you change supplier or tariff, a meter can temporarily lose its smart features and behave like a traditional meter until it is reconnected remotely.
  • Commissioning or firmware glitch: Like any connected device, a meter can occasionally need a remote update or reset to behave correctly.
  • A genuine fault: In rarer cases the meter itself develops a fault and needs an engineer.

How to fix a smart meter that is not working

Before contacting Fuse Energy, these steps resolve most display and connection problems:

  1. Wake the screen and check for a power cut:
    • Press a button on the meter to wake the display, as it may simply be asleep.
    • Check whether your lights and sockets are working. If you have lost power, wait until it is fully restored before expecting the meter to behave normally.
    • Give the meter a little time after any power interruption to restart and reconnect.
  2. Check the reading and any messages:
    • Note any on-screen message such as "no signal", "no comms", or an error code, as this helps customer support diagnose the issue.
    • If you also use an IHD and it is blank, try restarting it and keeping it within about 10 metres of the meter, as a blank IHD is a separate issue from the meter itself.
    • Allow up to an hour for the meter to reconnect to the network on its own.
  3. When to contact your energy supplier:
    • If the screen stays blank after a button press and the power is on, or a "no signal" message persists for more than 24 hours, contact Fuse Energy's customer support team.
    • They can run remote diagnostics, re-commission the meter, or arrange an engineer to investigate if a genuine fault is found.

Frequently asked questions about smart meter problems

Will I still be billed correctly?

In most cases, yes. A smart meter normally keeps recording your usage even when its screen is blank or it has temporarily lost signal, and it sends those readings to Fuse Energy once the connection is back. If you are worried, you can submit a manual reading to keep your account accurate.

Why does my smart meter say "no signal"?

This usually means the meter has lost its connection to the network it uses to send readings, often after a power cut or a local network outage. The meter keeps recording in the background. If the message does not clear within 24 hours, contact Fuse Energy so we can check the connection remotely.

Can I still read my meter manually?

Yes. You can read the figures directly from the smart meter's own screen and submit them to Fuse Energy, just as you would with a traditional meter. This is a useful backup if the meter has dropped its signal.

How can I track my usage if the display is not working?

If your smart meter is sending readings, you can view your usage in the Fuse Energy app or your online account, which is a reliable alternative to any physical display. For context, the average UK home uses around 2,700 kWh of electricity per year, so the app makes it easy to see where you sit.

What if the smart meter itself is faulty?

If the screen stays dead with the power on, or you suspect the meter is not recording, contact Fuse Energy. We can perform remote diagnostics and arrange for an engineer to investigate or replace the meter if needed.

Managing your energy should be simple and transparent. Fuse Energy provides clear pricing and an intuitive app so you always know what you are using, even if a screen lets you down. Our customer support team is on hand whenever you need help. Click here to switch to Fuse Energy today.
