How the DCC smart meter network operates

Using energy in your home

Every time energy is used, or generated, in homes with smart meters, they turn it into a packet of data. The data is securely wrapped, using two layers of encryption and a communications hub creates a home area network to receive it.

In-home display

From your home to the DCC

The hub transmits the data to an in-home display which shows how much energy is being used or sold back to the grid. The data is then transmitted from the home to a wide area network of mobile phone or radio masts, and from these to the DCC servers.

Our secure digital highway

Our security and technical operations centre is the nerve centre of the DCC network. Here our team continually monitor the performance, resilience, speed and security of the network. It operates entirely separately from the potential pitfalls of the public internet and operates to security levels endorsed by the National Cyber Security Centre, part of GCHQ. The DCC network never sees or keeps the data, it transports it securely straight to energy suppliers to access. They decrypt the data and use it to bill consumers accurately.


Protecting data on the smart meter network

Britain's smart meter network was designed with security at its core. It securely connects millions of households across the country to their energy data.
