Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what physical and digital hardening measures are being mandated for the UK’s energy transmission networks.

Great Britain has a highly resilient energy system. The Government takes the protection of energy infrastructure incredibly seriously.

We work closely with industry, the National Protective Security Authority, and the National Cyber Security Centre, to ensure energy infrastructure is proportionately protected against a range of threats, including malicious and accidental damage.

In 2026, the Government published the Energy Sector Cyber Security Strategy to strengthen cyber resilience across the sector. This is underpinned by the Network and Information Systems Regulations, which require operators to take robust security measures, assess risks and report significant incidents.
