Galaxy Redhill 15MW data centre consent: design notes for project engineers

First reported on New Civil Engineer
30 Second Briefing
Planning consent has been granted for a new 15MW data hub at Galaxy Data Centers’ Redhill campus in east Surrey, following approval by Reigate & Banstead Borough Council. The scheme will add significant electrical load and cooling demand to the existing technology site, requiring upgraded grid connections, high-capacity transformers and robust standby power systems. Civil and geotechnical teams can expect tight footprint constraints on a live campus, with heavy plant foundations, cable routes and drainage needing careful coordination with existing utilities and services.
Technical Brief
- Statutory planning conditions are likely to govern noise, traffic routing and construction working hours on the live campus.
- Early works packages will need to sequence utility diversions and temporary supplies ahead of main civils.
- Planning status enables detailed ground investigation commissioning, including boreholes, in-situ testing and contamination assessments.
- Council sign-off de-risks programme by reducing planning appeal uncertainty before major M&E orders are placed.
- Similar UK edge-of-town data campuses are using planning consent points to lock in grid-capacity reservation agreements.
Our Take
A 15MW facility at the Redhill campus places Galaxy Data Centers in the mid-scale tier of UK data hubs, which typically target rapid expansion phases if power and grid connections can be secured early.
Among recent UK Infrastructure items in our database, east Surrey has relatively few large-scale digital or energy projects, so this consent signals that Reigate & Banstead Borough Council is willing to host higher-intensity power users if planning and visual impacts are managed.
For contractors tracking the 826 Infrastructure stories in our coverage, data centre builds like this are emerging as a distinct workload segment, often demanding deep foundations, high-spec M&E integration and early coordination with utilities to avoid programme risk around energisation.
