Data Centre World is the UK’s largest data center exhibition and conference, drawing nearly 20,000 attendees to London’s ExCeL centre each March. The two-day event brings together operators, engineers, and solution providers across the full spectrum of data center infrastructure — from power and cooling to security and sustainability.

For engineers and facility managers, DCW London is a rare opportunity to see hundreds of vendors side-by-side, attend technical deep-dives on emerging cooling technologies and power architectures, and connect with peers from across Europe, the Middle East, and beyond. The 2026 edition features 700+ speakers across multiple stages covering AI infrastructure demands, liquid cooling at scale, grid constraints, and modular construction.
