Real estate investor Castleforge and Galaxy Data Centers have secured planning permission for a new data center outside London, UK.

The two companies this week announced that full planning consent has been granted for a new 15MW building at its Redhill campus.

Situated on the existing 3.1-hectare industrial estate at Foxboro Business Park in Surrey, the companies aim to develop a single two-story data center with four data halls.

After filing for planning permission in January, the project secured approval from Reigate & Banstead Borough Council’s planning committee last week. Buildings 1 and 2 on the site are set to be demolished to make way for the new development.

The new facility will support a local waste heat recovery initiative, initially on-site, with the option to supply the neighboring residential heat network.

Mike Adcock, head of investments at Castleforge, said: “Securing planning consent for our new development at Redhill is a major milestone in our plans to deliver high-quality, sustainable digital infrastructure to one of the world’s most important data center markets. Demand for capacity in and around London continues to outpace supply, and this consent enables us to bring forward the additional power and scale required to serve enterprise, hyperscale, and Edge customers.”

The Redhill campus currently spans 11,800 square meters (127,015 sqm) across three buildings, totaling 26MW. The two firms acquired the campus in late 2024. Launched in 2008, the site was previously operated by Digital Realty as its LGW10 facility. Digital said it sold its site in Redhill for £64 million ($80m).

Paul Leong, CFO and partner of Galaxy Data Centers, added: “This planning consent is a pivotal step in realizing the long-term vision we set out when we acquired Redhill alongside Castleforge. We are proud to be delivering a development that combines operational excellence with meaningful sustainability outcomes, and we look forward to bringing the project forward in close collaboration with the local community.”

Part of investment firm Galaxy Capital Partners, Galaxy Data Centers is a global data center operator and advisory provider founded in 2016.

Founded in 2010, Castleforge invests in real estate located in and around select UK and European cities. The Redhill campus was seemingly the company’s first data center investment.
