UK real estate firm Segro has signed a pre-lease agreement to develop a data center outside London in Slough.

The company has also got the green light for another data center project in West London in partnership with Pure DC.

Segro signs pre-lease in Slough

The company this week announced it has signed an agreement to develop a powered shell data center for an existing customer on the Slough Trading Estate.

The three-story building will provide 30,000 sqm (322,917 sq ft) of data center space and 50MW of utility power. Planning permission is in place via the Slough Trading Estate Simplified Planning Zone.

Full details of the project weren’t shared.

Segro gets greenlight for Pure project

This week also saw Segro announce that it has received planning committee approval for its first fully fitted data center, which it is developing under a joint venture with Pure Data Centres Group at Segro’s Premier Park in Park Royal, West London. The facility will total 70MW of utility power and 56MW of IT capacity.

Pure and Segro announced plans for a 30,000 sqm (322,917 sq ft) data center in May 2025. The facility is set to be leased to an unnamed hyperscaler.

Andrew Pilsworth, managing director of data centers and strategic partnerships at Segro, said: “These two announcements demonstrate further progress in our strategy to execute on the 2.5GW+ opportunity in our powered land bank. The critical mass of data centers we have built up at Slough over the last 20 years, together with the Simplified Planning Zone status we have secured there, was integral to enabling us to work with an existing customer to expand its campus, while allowing Segro to profitably utilize a relatively small 3.5-acre plot.”

Pilsworth continued: “Securing planning committee approval at Premier Park is also an important milestone for both our Pure JV at the site and, more broadly, in the evolution of Segro’s fully fitted data center development strategy.”

Founded in 1920, Segro is a UK-based real estate investment trust (REIT), listed on the London Stock Exchange and Euronext Paris. It develops warehouses and other industrial buildings at sites across the UK and Europe.

Segro has been providing powered shells to data center customers for around 20 years, and the company said it has some 500MW of data center capacity in operation or development around Slough. It added that the data center opportunity within its portfolio equates to more than 1.8GW of further potential additional capacity across the UK and Continental Europe.

All of its lettings to date have been to colocation providers so far, but the company is now moving into providing fully fitted-out data centers and targeting hyperscalers directly.
