Many people assume that once a smart meter is installed, everything should work automatically.
In reality, installation is only one part of the process.
For a smart meter to work correctly, it must also be fully commissioned and registered within the national smart meter network.

What Commissioning Means
A smart meter installation involves several steps:
1.Electricity meter installed
2.Gas meter paired to electricity meter (HAN connection)
3.Communications hub connected to the network
4.Meter registered with the national data system
5.Supplier systems configured to access the meter
The communications network is managed by
If any of these steps fail, the meter may appear installed but not function fully as a smart device.

Signs Your Smart Meter May Not Be Fully Commissioned
Common symptoms include:
• supplier asking for manual meter readings
• smart tariffs unavailable
• in-home display not updating
• gas usage missing from the display
• estimated energy bills despite smart meter
These issues can occur even when the meter itself is working correctly.

Why This Sometimes Happens
During the national smart meter rollout, millions of meters were installed across the UK.
In some cases, installations were completed physically but system configuration was delayed or incomplete.
This can result in a meter that appears to be installed but does not yet operate with full smart functionality.

How the Problem Is Usually Fixed
In many cases the solution does not require replacing the meter.
Instead, the supplier may need to:
• complete commissioning in their systems
• reconnect the meter through the network
• update configuration settings
Once this process is finished, the meter should operate normally.

When to Contact Your Supplier
If your smart meter appears installed but is not working as expected, contact your supplier and ask them to check:
• whether the meter is fully commissioned
• whether the meter is connected to the national smart meter network
Once the setup process is completed, the smart features should begin working.
