Understanding why your smart meter isn't working

Smart meters are designed to automatically send energy readings to your supplier, typically at midnight, via the Data Communications Company (DCC) network. This enables accurate billing and helps you track your energy consumption. When this communication fails, your smart meter is considered "not working".

How smart meters communicate

Your smart meter communicates with your energy supplier through the secure national DCC network. This network is specifically designed for smart meters to transmit data safely and reliably. Gas smart meters are battery-powered and communicate with your energy supplier via the electricity meter's communications hub. This means an issue with your electricity meter's communication can also affect your gas meter's ability to send readings.

Common smart meter issues

A common sign of a smart meter issue is a blank or unresponsive in-home display (IHD). This doesn't always mean the smart meter itself is faulty; the IHD might simply be in power-saving mode or have lost connection to the meter. Other problems include the smart meter not sending readings, which leads to estimated bills, or displaying incorrect information. A "not working" smart meter often means it is not communicating with your energy supplier, which typically results in estimated bills.

Step-by-step troubleshooting for your smart meter

Before contacting your energy supplier, there are several steps you can take to diagnose and potentially resolve the issue yourself.

Check your in-home display (IHD)

First, check your IHD. Is it completely blank, or is it just in power-saving mode? Try pressing any button to wake it up. Ensure it's plugged in and has power. If it's battery-powered, check the battery level or replace them if necessary. Sometimes, simply moving the IHD closer to your electricity meter can re-establish its connection.

Restart your smart meter and IHD

A simple restart can often fix connectivity issues. For your IHD, unplug it from the mains (if applicable) or remove its batteries, wait a few minutes, then plug it back in or reinsert the batteries. For the smart meter itself, you generally cannot restart it directly. However, if your IHD is connected to the meter, restarting the IHD can sometimes prompt the meter to re-establish its communication.

Distinguishing meter issues from power cuts

It's crucial to determine if the problem is with your smart meter or a wider power cut in your area. If your entire property has lost power, it's likely a power cut, not a smart meter fault. You can check for power cuts in your area by visiting your local Distribution Network Operator's (DNO) website or calling 105, the free national power cut helpline. If your neighbours also have no power, it confirms a network issue. If only your smart meter or IHD is affected, and your power is otherwise on, the issue is likely specific to your meter.

What a non-working smart meter means for your bills

When your smart meter isn't communicating, it can't send automatic readings to your energy supplier. This has direct implications for how your energy usage is recorded and billed.

How estimated billing works

If your smart meter isn't sending readings, your energy supplier will issue estimated bills. These estimates are based on your past energy consumption, the consumption of similar households, or other factors. While estimated bills aim to be accurate, they can sometimes be higher or lower than your actual usage. This can lead to overpaying or underpaying, potentially resulting in a 'bill shock' when a correct reading is eventually obtained.

Your rights regarding estimated bills

Ofgem, the UK's energy regulator, sets Guaranteed Standards of Performance for energy suppliers, which include requirements for smart meter installation and repair. If your smart meter isn't working, your supplier has obligations to resolve the issue. While the problem is being addressed, you have the right to ensure your bills are as accurate as possible. You can submit manual meter readings to your supplier to help them adjust estimated bills closer to your actual usage. If your supplier fails to meet these standards, you may be entitled to compensation.

When to contact your energy supplier

If troubleshooting steps don't resolve the issue, or if you suspect a more serious fault, it's time to contact your energy supplier.

Information to provide your supplier

When you contact your supplier, be prepared to provide:

  • Your account number and address.
  • Details of the smart meter's behaviour (e.g., blank screen, no readings, specific error messages).
  • Any troubleshooting steps you've already taken (e.g., restarting IHD, checking for power cuts).
  • The meter serial number (MSN) from your electricity and gas meters.

Addressing specific scenarios: RTS meters and switching

If you have a Radio Teleswitch Service (RTS) meter, it's important to know that these are legacy meter types being phased out across the industry. The RTS signal is being switched off, meaning these meters must be replaced with smart meters. RTS meters are unsupported for switching to modern energy suppliers like Fuse Energy until they are replaced by your current supplier. Your existing supplier is responsible for upgrading your RTS meter to a smart meter. Fuse Energy does not install, convert, or upgrade RTS meters.

What is the DCC network?

The DCC operates the secure national smart metering network. It enables reliable and secure communication between smart meters and energy suppliers, ensuring that energy usage data is transmitted accurately and efficiently for billing and monitoring purposes.
