If I have an existing smart meter, will it remain smart if I change supplier?

In time, yes. All smart meters have to comply with a smart metering equipment technical specification (SMETS) version.

If the customer has the latest version (SMETS2), the meter will retain its smart capability.

However, if the meter is a SMETS1, some customers may experience meter interoperability issues meaning the new supplier may not be able to retrieve readings remotely.

There is an ongoing programme within the industry to ensure all SMETS1 meters are enrolled with the DCC to commence making them fully smart in 2019.
