Microsoft exits Nscale UK data centre deal

Microsoft has pulled out of its agreement with Nscale for a planned data centre in Loughton, Essex, as reported on 18 October 2026. The facility had been positioned as a significant new UK site for cloud and AI infrastructure. Microsoft’s exit removes the leading prospective customer for the project.

The Loughton development had been expected to feature Microsoft as the anchor tenant, giving the project a major long-term customer commitment. Coverage described the arrangement as central to the commercial rationale for the site.

Authorities have told Nscale they do not expect to be able to provide a grid power supply to the Loughton site until the 2030s. This timeline reflects substantial delays compared with earlier expectations for bringing the facility online.

Reports describe the project as having faced repeated delays and grid-connection problems. The lack of timely access to adequate power is a key operational obstacle to progressing the data centre as originally planned.

The reported agreement between Microsoft and Nscale for the Loughton site had been linked to Microsoft renting compute capacity at the facility. Coverage connected this to a large planned deployment of Nvidia (NVDA) AI chips, estimated at about 23,000 units.

With Microsoft no longer proceeding under the existing arrangement, the original scale and configuration of AI infrastructure at Loughton are now uncertain. The loss of a major tenant raises questions over how and when the capacity that had been planned will be utilised.

The withdrawal comes at a critical time for Nscale, which is preparing for a US initial public offering. The Loughton facility had been presented as its first British data centre and a cornerstone asset in its growth story.

Published reports frame the change in status of the Microsoft deal as a material setback for Nscale’s plans. The combination of power supply constraints and the loss of an anchor tenant presents both operational and commercial challenges as the company approaches public markets.

The situation at Loughton highlights the importance of grid availability for new data centre projects in the UK. Authorities’ indication that adequate power may not be available until the 2030s underlines the scale of local infrastructure constraints.

For hyperscale and AI-focused facilities, power reliability and timelines are central to investment and tenancy decisions. The Loughton experience illustrates how grid connection issues can directly affect large-scale cloud and AI deployment plans.
