Pulsant expands Milton Keynes data centre for AI boom

Pulsant has completed a £10 million expansion of its Milton Keynes data centre, adding a high-density data hall as demand rises for artificial intelligence infrastructure outside London.

The build adds 1.2MW of capacity. Pulsant described it as part of a wider shift towards regional locations for compute and connectivity as London data centres face space and power constraints.

Milton Keynes sits within the Oxford-Cambridge technology corridor and has become a growing hub for digital businesses. The area includes companies employing about 570,000 people and generating £135bn in annual turnover, according to figures cited in the announcement.

High-Density Build

The new hall is designed for high-density computing. Pulsant expects demand from AI, machine learning and accelerated computing workloads, which are increasingly used in financial services, healthcare, biotech, IT services and gaming.

Pulsant also positioned Milton Keynes as an option for firms that need proximity to the capital without relying on London data centres, citing two milliseconds of latency to London Docklands and Slough.

The site is part of Pulsant's UK footprint of 14 data centres. These facilities connect through a network described as 400Gb-capable. Customers at Milton Keynes also gain access to more than 1,600 cloud services, network providers and partners.

London Constraints

Capacity limits in London have become a recurring issue for UK operators and customers. New developments around the capital have faced tight power availability, long connection timelines and pressure on land. As a result, operators have looked to regional sites with strong fibre connectivity for both primary infrastructure and overflow capacity.

Pulsant described Milton Keynes as a location that keeps services close to London while reducing reliance on the capital's core clusters. It also said the expansion strengthens its platformEDGE framework, which it uses to describe its distributed data centre model across the UK.

Interest in UK-hosted infrastructure has also risen alongside AI adoption and data sovereignty requirements. Many organisations, particularly in regulated industries, prefer to keep sensitive data and critical workloads within UK jurisdiction.

Policy Backdrop

The announcement comes amid government plans for domestic AI investment. The UK government has committed almost £500 million to initiatives aimed at strengthening AI capabilities, including a Sovereign AI Unit, according to the note accompanying the announcement.

Milton Keynes has promoted a digital and innovation strategy in recent years, aiming to attract technology and creative industries. That positioning has raised the city's profile as a potential landing spot for infrastructure providers and technology firms.

Expansion Plans

Pulsant plans to roll out its high-density model to other regions as demand grows for sovereign infrastructure and advanced compute. It did not name the next sites or provide investment figures beyond Milton Keynes.

Chief executive Rob Coupland said the investment responds to what Pulsant sees as a sharp rise in demand for denser compute environments.

"The £10m expansion of our Milton Keynes data centre is another big investment in our digital platform to meet hunger for high density compute power," Coupland said.

He said capacity constraints are becoming more pronounced as AI projects move from experimentation into production.

"UK digital infrastructure is facing unprecedented demand. With AI-ready capacity in short supply, bringing high performance, flexibility and choice to regional locations is critical.

"For organisations looking for ultra-low latency, international connectivity and UK sovereign compute power, Milton Keynes is a great option compared to constrained and costly London data centres which lack the opportunity for expansion."

Coupland added that customers want alternatives to the main London cluster without sacrificing network performance.

"Our unique platform gives local, national and international clients the flexibility to circumvent some of the risks associated with the London cluster, while maintaining high performance, resilience and connectivity."
