Quick Summary

Microsoft has withdrawn from a major AI datacentre project in Loughton, Essex, due to power supply issues, causing significant setbacks for Nscale, the British firm behind the development. Initially planned as the largest AI datacentre in the UK and expected to open next year, the project faced delays when it was revealed that the site was still an operational scaffolding yard. With Microsoft’s departure, which leaves Nscale without its primary customer, the company is now exploring alternative power sources for the Loughton site while maintaining its commitments to other projects and partnerships in Norway.

Story summary

Microsoft pulled out of a planned £2 billion AI data center project in Loughton, Essex, due to concerns about delayed power supply access until after 2030. The UK government had previously highlighted this facility as the country’s largest AI datacenter when it was announced in 2025. Despite losing its anchor tenant, Nscale remains committed to the Loughton project and is exploring alternative power sources. Microsoft stated that this decision only affects a single site but maintains a strong long-term relationship with Nscale for other projects globally. The company also emphasized its ongoing £22 billion UK investment plan, stressing it will continue to support AI growth in regions like Manchester.

🔮 It may be a wetter Monday morning than London’s mayor would have dreamed of, but Sadiq Khan hailed it a “momentous day”.
🔮 In a development that would honour a promise made by Andy Burnham in his Makerfield byelection campaign before entering Downing Street, the planned change, first reported by the Sunday Times, would result in the threshold at which small firms start paying business rates rising from £12,000 to £18,000.
🔮 Now there are further concerns after Microsoft, one of its largest planned customers and expected to have been the anchor tenant, informed the company that it was pulling the plug on its agreement.
