DC01UK has sold its 85-acre South Mimms data centre site in Hertfordshire to data centre operator Equinix for an undisclosed price.
The site in Hertsmere, which has been renamed the ‘Hertfordshire Campus’ by Equinix, has a total investment value in the region of £3.9bn.
When fully built out, the campus will provide more than 2m sq ft of cutting-edge data centre space.
James Craig, director of DC01UK, said: “This is a landmark moment for the UK and a powerful example of local entrepreneurship driving national innovation. The ambition behind the DC01UK project is extraordinary and we are delighted that the vision for this project will be taken forward by leading experts committed to delivering it to the highest standards, maintaining our ambition, realising the community benefits and embedding themselves in the growth and future of Hertfordshire. For us, it’s a proud moment that also marks the beginning of an exciting new chapter as we continue to progress other UK data centre development opportunities to drive further innovation and investment in this space across the UK.”
Andy Brewer, director of DC01UK, added: “This deal marks a significant step forward for this world-class project and for the UK’s digital future. It was born of local ingenuity and determination and aligns closely with the government’s ambition for the UK to be a global leader in AI and advanced technology. With one of the world’s largest operators now taking our vision forward, the project is entering an exciting new phase, one that will help position the UK at the forefront of the data revolution.”
Stephen Beard, global head of data centres at Knight Frank, who advised on the project, said: “This is a seismic moment for the UK’s infrastructure landscape. The scale, ambition and strategic value of this site are unmatched. It’s rare to find a location that ticks every box – power, connectivity, proximity to key markets – and this one does. Today’s announcement gives the UK a major leg up in the global AI infrastructure race.”
Michael Umfreville, head of data centres at BNP Paribas Real Estate, which advised Equinix, added: “This landmark transaction represents a major milestone for the UK’s digital economy. Our longstanding relationship with Equinix has seen us advise on a number of strategic data centre transactions over the years – including real estate transactions in East and West London. This latest deal underlines both Equinix’s continued commitment to the UK and the importance of BNP Paribas Real Estate’s real estate advice as the client focuses on their data centre investment in driving national growth and resilience.”
