The company plans to invest approximately £3.9 billion into the project, which aims to deliver over 250MW of compute capacity, reinforcing the UK’s critical national infrastructure. Once fully developed, the facility will provide world-class digital services and skills, supporting a wide range of sectors including healthcare, life sciences, public sector, finance, manufacturing, and entertainment. The project underscores Equinix’s commitment to the UK’s ambitions to lead in sovereign AI.

Construction of the site, previously known as DC01UK, is expected to generate around 2,500 local jobs during the build phase. When operational, it will create over 200 permanent positions, most of which will be highly skilled roles. According to KPMG, the employment impact could contribute roughly £120 million in wages, with the broader UK economy benefiting from up to £3 billion in annual Gross Value Added (GVA) during construction and approximately £260 million once fully operational. These figures reflect the extensive economic activity from supply chain engagement, employment wages, and related spending.

Equinix emphasises its commitment to community partnership at the Hertfordshire Campus, planning to collaborate closely with local residents and businesses. Initiatives will include investments in education, employment, and biodiversity programs designed to deliver tangible benefits to the region.

With a 27-year history supporting digital progress across six continents, Equinix operates more than 270 data centres supporting over 1,300 UK-based customers. The Hertfordshire development will connect businesses of all sizes to secure, scalable, and AI-ready global infrastructure. Sustainable practices are a core part of the project, with plans for dry cooling systems that minimise water use, preserving 54% of the land as open space, and creating new ecological habitats to achieve at least a 10% biodiversity net gain.

“The UK is a cornerstone of the global economy and the ideal location for our most significant European investment to date. This development not only provides substantial data centre capacity to support the UK’s AI ambitions but also marks the evolution of a long-term partnership with local and national communities,” said James Tyler, UK Managing Director of Equinix.

“This £3.9 billion investment will enable UK businesses — from life sciences to financial services — to connect instantly with global markets, fuelling AI growth, boosting economic development, and creating hundreds of high-quality jobs. It ensures the UK remains at the forefront of the digital revolution, benefitting every community,” said Liz Kendall, Secretary of State for Science, Innovation and Technology.

“This investment reflects the critical role of data centres as the backbone of the UK economy. Continued sustainable and resilient digital infrastructure is essential for realising the UK’s AI and economic ambitions outlined in our Foundations for the Future report,” said Luisa Cardani, Head of Data Centres at techUK.

This project complements Equinix’s existing UK infrastructure, which includes 14 data centres supporting over 10,000 customers and employing more than 1,200 people, contributing approximately £145 million annually to household income. All of Equinix’s UK facilities are designed to export heat for local energy conservation, reinforcing the company’s commitment to sustainability and community well-being.
