It is the latest stage of expansion of the site which was acquired by real estate investor Castleforge in partnership with Galaxy Data Centers last year.

The new owners are planning to invest another £200m in the site bringing its gross project value to around £500m.

Situated on the existing 3.1-hectare industrial estate at Foxboro Business Park, the consented project comprises a single two-storey data centre with four data halls and an accompanying office block.

The expansion follows surging demand for digital infrastructure across the London market, driven by advancements in AI, cloud computing and hybrid workloads.

Mike Adcock, Head of Investments at Castleforge, said: “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.”

Paul Leong, Chief Financial Officer and Partner of Galaxy Data Centers, added: “This planning consent is a pivotal step in realising the long-term vision we set out when we acquired Redhill alongside Castleforge.

“The new facility will significantly expand the capacity available to our customers and ensure Redhill is positioned to meet the evolving needs of edge, hyperscale and enterprise users.”

The Redhill campus currently spans 11,800 square metres across three buildings.
