Real estate investor Castleforge, in partnership with full-service data centre operator and advisory firm Galaxy Data Centers, has received full planning consent for a new 15MW data centre development at its Redhill campus.           

Located just outside of London, the new development will include four data halls and support a local waste heat recovery initiative.

Following approval from Reigate and Banstead Borough Council’s Planning Committee, the consented project marks a significant step forward in the joint venture’s plans to expand digital infrastructure capacity in the London market, following the partnership’s £100m-plus investment in the existing Redhill Data Centre campus in December 2024.

The scaling of the campus will see a follow-on £200m investment into the campus with a gross project value of around £500m.

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

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 centre 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. We are particularly proud of the project’s sustainability credentials, including the potential to export waste heat to local homes, which reflects our commitment to creating places that deliver lasting value for both customers and the surrounding community.”

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. 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.”

The Redhill campus currently spans 11,800 square metres across three buildings serving a dynamic existing customer base, including Fortune 500 enterprises across financial services, AI and other sectors.
