Pure DC and SEGRO Investing in London AI Data Centre Project

Pure Data Centres Group (Pure DC) and SEGRO have confirmed that their joint venture has received final planning committee approval for a 56MW data centre at Premier Park in West London. The development marks the first milestone in a partnership aimed at expanding AI infrastructure across Europe, with a focus on hyperscale demand and constrained urban markets.

The scheme brings together SEGRO’s industrial and logistics portfolio with Pure DC’s experience in hyperscale and AI campuses. SEGRO controls sites in key availability zones – areas with strong connectivity and power access – while Pure DC specialises in designing and delivering large-scale data centre environments. The collaboration targets locations where power, land and planning approvals remain limited.

London capacity pressure shapes development strategy

The Premier Park project sits within one of London’s main digital infrastructure corridors, where demand for data centre capacity continues to rise. The facility is designed as a purpose-built, liquid-cooled environment.

Gary Wojtaszek, Executive Chairman & Interim CEO of Pure DC, says: “The joint venture between Pure DC and SEGRO at Premier Park is a great example of the potential from a real estate developer and a DC operator working together to unlock the next wave of hyperscale and inference AI infrastructure across Europe.

“By combining strategic urban sites such as the site owned by SEGRO in Park Royal, with Pure DC’s expertise in designing and delivering hyperscale campuses, there is the potential to bring forward digital infrastructure in markets where it has historically been extremely difficult to build.”

The site supports high-density cloud and AI workloads, including advanced graphics processing units. These processors handle complex computations required for AI training and inference. The facility forms part of a wider cluster of Pure DC locations positioned milliseconds apart across the company’s London availability zones.

Gary continues: “London is one of the most supply-constrained data centre markets in the world.

"What makes Pure DC unique is that we can offer hyperscale customers something that almost never exists in the London market — the ability to launch a fully redundant three-site availability zone within the same metropolitan area. For cloud providers deploying the next generation of AI inferencing infrastructure, that level of immediate scale and resiliency is incredibly valuable.”

Power, scale and efficiency at the core

The development spans 24,000 square metres and secures around 70MVA of power through a new substation. MVA, or megavolt-amperes, measures electrical capacity supplied to the site. The project targets a power usage effectiveness (PUE) of about 1.2. 

Closed-loop liquid cooling forms part of the design, allowing the system to reuse coolant without exposure to external contaminants. This approach supports consistent thermal management for dense computing environments.

David Sleath, CEO of SEGRO, says: “The rapid growth of cloud computing and AI is driving unprecedented demand for digital infrastructure across Europe’s largest cities. SEGRO is extremely well-positioned to respond to this with our 2.5GW+ powered land bank focused on key Availability Zones.

“Our Joint Venture with Pure DC at Premier Park is a great example of how we can combine one of our industrial sites with Pure DC’s deep expertise in hyperscale data centre development to unlock new opportunities and create long-term income and value from our land bank.”

Investment, jobs and local engagement

The Premier Park scheme represents around £1bn (US$1.3bn) in gross capital investment. Construction activity supports hundreds of roles, while ongoing operations contribute to the regional economy. Once active, the LON02 campus generates about £52m (US$69.4m) each year locally and contributes £2.3m (US$3.1m) annually in business rates.

Beyond infrastructure, the partners outline commitments to local communities near the site. More than £3m (US$4m) is allocated to long-term initiatives, including a digital fund. This programme aims to support 1,000 students pursuing science and technology careers, assist 150 local businesses with digital adoption and provide over 200 residents with digital skills and employability training.

The project illustrates how data centre operators and real estate developers align resources to address constraints in major urban markets. By combining land access, power provision and technical expertise, the joint venture establishes a model for delivering high-density, AI-ready infrastructure within cities where expansion remains complex.
