The UK Government announced that data centres across the country have been classified as Critical National Infrastructure (CNI).

The move, confirmed by Secretary of State for Science, Innovation and Technology, Peter Kyle, is intended to enhance the protection of sensitive data and ensure the resilience of these facilities against cyber threats, IT disruptions, and other risks.

Data centres will now be prioritised for Government support during critical incidents. This marks the first CNI designation in nearly a decade, following the inclusion of the Space and Defence sectors in 2015.

Technology Secretary, Peter Kyle, said ‘data centres are central to modern life’.

“Including them in the CNI regime will improve coordination with the government to guard against cyber criminals and unexpected events,” added Kyle.

The new designation will create a dedicated team to monitor threats and coordinate responses, as well as access to security agencies like the National Cyber Security Centre. The Government aims to provide the sector with additional support to recover from disruptions and minimise the impact of potential attacks.

Designation to Deter Cyberattacks

The Government hopes the new status will deter cyberattacks, such as the CrowdStrike incident earlier this year that affected GP surgeries by disrupting access to patient information. The CNI designation will aim to mitigate such risks and ensure services remain operational during crises.

“We welcome the Government’s recognition of the critical role data centres play in the economy. This decision will help ensure the stability of the sector and its ability to support both the UK and global economies,” said Bruce Owen, UK Managing Director at Equinix.

The UK’s data centre sector, already the largest in Western Europe, is expected to benefit from the additional protections, potentially improving confidence in further investment. The new designation forms part of a broader effort by the government to strengthen the nation’s cyber defences, alongside the proposed Cyber Security and Resilience Bill.

“Data centres are a key part of the UK’s modern economy. We look forward to working with the Government to ensure the successful implementation of these measures and support the ongoing growth of the sector,” said Matthew Evans, Director of Markets at techUK.

The designation of data centres as Critical National Infrastructure is intended to strengthen their resilience and safeguard essential services, with the Government positioning the move as an important step in securing the UK’s digital future.

The announcement coincides with plans for a £3.75 billion ($4.95 billion) investment in what could become Europe’s largest data centre, to be built in Hertfordshire. The project, led by DC01UK, is expected to create 700 local jobs and support thousands of tech roles across the country.

“The £3.75 billion investment is a sign of confidence in the UK’s digital infrastructure … It shows the importance of ensuring that technological advancements contribute to economic growth,” added Kyle.
