The UK is approving 1.2 GW of new hyperscale data centre capacity in 2026. The fire safety implications are significant — and the regulatory framework is still catching up.. The Boom The Government's removal of data centres from the planning moratorium has triggered a development surge. In 2026 alone: 1.2 GW of new hyperscale capacity in planning 18 major projects announced across England, Scotland, and Wales £8.4 billion of investment committed Major operators: Microsoft, Google, AWS, Meta, Equinix Fire Safety Challenges Scale — Hyperscale data halls now exceed 100,000 sq ft per hall. Conventional design rules become inadequate at this scale. Concentration of risk — UPS rooms with megawatt scale lithium ion battery banks. The Singapore Loyang fire (2024) demonstrated the consequences. Business continuity criticality — Single facilities now host services used by hundreds of millions of users. Regulatory framework — UK building regulations weren't designed for hyperscale data centres. Significant performance based design required. Best Practice Emerging 1. VESDA aspirating detection in all server halls (very early warning) 2. Clean agent suppression (FK 5 1 12 / Novec 1230 or IG 541) 3. Compartmented data hall design — fire rated separation between halls 4. Specialist UPS room design — separate compartmentation, off gas detection, water suppression 5. CFD smoke modelling — for complex airflow scenarios 6. Specialist FRS coordination — many sites located outside major urban areas Need Expert Fire Safety Advice?
