The Halo

Building Overview

Jaguar delivers a major M&E contract, supporting a £1M+ portfolio of properties operated by The Doctors Laboratory (TDL), the UK’s leading independent provider of specialised pathology and clinical laboratory services. The portfolio spans a diverse mix of mission-critical facilities, including:

• The Halo Building
• 60 Whitfield Street
• 75–76 Wimpole Street
• Elstree
• Tavistock House

TDL plays a vital role in supporting general practitioners, hospital specialists, community health teams, and patients nationwide, requiring high-resilience engineering systems that ensure continuous laboratory operations and maintain the integrity of critical diagnostic work.

The Halo Building – Flagship of the Portfolio

The Halo Building serves as TDL’s largest and most complex operational hub. Spanning 120,000 sq ft, it houses highly specialised pathology laboratories, clinical testing environments, cold storage, and around-the-clock operations essential to patient care.

Operating in such a high-risk and critical environment demands unwavering continuity of M&E performance, robust redundancy planning, and ongoing resilience improvements. The work requires expert management of specialist HVAC, extraction, and filtration systems, alongside high-integrity electrical infrastructure that supports sensitive laboratory equipment. Every aspect of service delivery must meet strict clinical and laboratory regulatory requirements, while still driving energy efficiency without compromising resilience. Drawing on extensive experience managing complex estates and mission-critical systems, Jaguar provides TDL with stable, dependable building performance that safeguards essential clinical operations.

Our Approach

Jaguar’s service model is built around a dedicated, multi-disciplinary engineering team of twelve, permanently embedded across the portfolio. This team manages all daily M&E activity, encompassing planned and reactive maintenance, 24/7 resilience coverage, real-time building performance monitoring, and comprehensive compliance and safety assurance, while also responding rapidly to any critical-system alarms.

Energy and sustainability innovation is a central part of the approach. Working closely with TDL, Jaguar is implementing a series of no-cost and low-cost efficiency measures, guided by live building data streamed into our Building Performance Centre. This data-driven method enables real-time consumption monitoring, early identification of anomalies, waste reduction without affecting clinical activities, improved asset efficiency, and the delivery of actionable insights tailored specifically to the demands of laboratory environments.

By combining technical expertise, robust engineering processes, and forward-thinking sustainability initiatives, Jaguar is providing TDL with reliable, high-performance M&E services that directly support essential healthcare provision across the UK.
