Frequently asked questions
Can my smart meter be hacked directly?
Direct attacks on UK smart meters are rare due to the regulated DCC network. Most real-world risk sits with supplier apps, household passwords and connected third-party devices.
What's the difference between SMETS1 and SMETS2?
SMETS2 meters use the national DCC network and generally have better long-term security and switching support than older SMETS1 devices.
Is this a formal audit?
No. It's general guidance to help UK households improve everyday smart meter and account security.
