How we ensure security of our networks in the UK

Ensuring the security of our information, data, physical infrastructure, and property allows us to protect the UK’s energy supply and provides confidence in our organisation for colleagues, customers and stakeholders. We use best practice frameworks to implement appropriate and proportionate security measures related to cyber, physical, personnel and people security. These actions enable us to safeguard our organisation and keep our colleagues secure. 

Our People: If you see something, say something 

At National Grid, our greatest asset in protecting the grid is our people. We empower our employees to speak up if something doesn’t seem right. Reporting suspicious behaviour is made easy and convenient, and we ensure that all reports are addressed promptly and efficiently. Our robust response, recovery and continuity plans are proven to be effective against potential threats, minimising any impact on our organisation. 

Evolving security measures for a safer grid

We collaborate closely with local law enforcement and government agencies to continuously review, update and test our security controls. This ensures that we provide appropriate levels of mitigation and can respond proactively and efficiently.  

Given the vastness of our organisation, with sites and offices spread across the UK, we have heavily invested in physical security. Our around-the-clock monitoring and surveillance ensure the highest level of protection. Some of our security measures are visible, while others operate behind the scenes.
