Data Centre Construction and Fit-Out — London, UK

Discover how Craftex delivered a secure, scalable, and energy-efficient data centre for a leading FinTech company in London — purpose-built for high uptime, seamless tech integration, and future expansion.
After completing a series of office refurbishments for the same client, Craftex was appointed to design and deliver a new data centre facility within their London headquarters.
The client required a space that could host mission-critical IT systems with redundant power, advanced cooling, and full compliance with Tier 3 performance standards.
Craftex’s team led the end-to-end design, construction, and commissioning process, transforming an unused basement area into a fully operational, high-resilience data environment.

SERVICES
Data centres demand precision. From electrical continuity to environmental control, every component has to perform flawlessly.

Creating a Resilient Infrastructure Foundation


Our engineering and construction teams coordinated closely to deliver:

  • Dedicated power distribution with UPS and generator integration ensuring continuous operation.
  • Hot and cold aisle containment for efficient airflow and heat management.
  • Structured CAT6A and fibre cabling for fast, organised, and scalable connectivity.
  • Environmental monitoring systems (BMS integration) to track temperature, humidity, and energy performance in real time.

This robust foundation positioned the client’s facility to support both their current workloads and future expansion without structural rework.
Security and efficiency were at the heart of this build.
To meet industry standards, we implemented:
  • Access-controlled server rooms with biometric authentication and CCTV surveillance.
  • FM-200 fire suppression systems to protect sensitive equipment.
  • High-efficiency CRAC units reducing energy consumption by 15%.
  • Acoustic insulation and vibration damping, ensuring noise and interference remained below operational thresholds.
Our design also included modular layouts and raised flooring to simplify future upgrades or equipment changes, reducing disruption and downtime.

Secure, Efficient, and Future-Ready Design

Throughout the 10-week construction phase, Craftex maintained full coordination with the client’s IT and facilities teams.
All works were staged to minimise disruption to adjacent office areas, with critical system commissioning completed over a single weekend to align with network maintenance schedules.
Our transparent project communication ensured all milestones were met safely, on time, and within budget.
Seamless Delivery & Client Collaboration
The finished space now delivers:
  • 99.98% system uptime capacity, matching Tier 3 resilience.
“Craftex’s precision and professionalism made what seemed like a technical challenge into a smooth, efficient project. The result exceeded expectations.”
— Head of Infrastructure, FinTech Client

  • A 20% reduction in cooling energy through precision environmental design.
  • Enhanced data security and audit-ready compliance for financial regulators.
  • A scalable hub capable of doubling rack capacity without additional civil works.

Outcome & Client Impact

We design and deliver critical infrastructure environments that are secure, efficient, and built to scale. From electrical resilience to BMS integration, every project is engineered for performance and longevity.
