How secure are smart meters in the UK? What you need to know
Smart meters are built to be safe, secure, and regulated. For most households, they offer peace of mind alongside better energy tracking. Their design is based on expert-reviewed smart meter data privacy and cybersecurity standards to ensure they meet the UK’s highest security expectations.
Designed with security in mind
From day one, smart meters have been built with cybersecurity experts. Their goal was to ensure data transmission is encrypted, protected, and compliant with UK privacy laws.
Secure data transmission
Smart meters use a private WAN network, not the internet.
They use end-to-end encryption to prevent interception.
Data never includes personal identifiers.
Who oversees the security
The system is managed by the Data Communications Company (DCC).
It’s regulated by Ofgem, the energy regulator.
It complies with UK GDPR and is reviewed by the National Cyber Security Centre (NCSC).
Expert backing
A 2022 report from the UK Government Office for Science confirmed that smart meters pose a very low cybersecurity risk, especially compared to internet-connected devices like routers, smartphones, or smart TVs.
Conclusion
Smart meters are built to be safe, secure, and regulated. For most households, they offer peace of mind alongside better energy tracking.
