NHS Blood and Transplant Service


Case Study

NHS Blood and Transplant Service

Regulated Multi-Site Healthcare Delivery

Estate Overview

  • Partner since 2016
  • 44 sites across London, Hertfordshire, South & South-West
  • 100+ operatives including cleaning, supervision, reception and porter services
  • Coverage includes blood centres, donor centres, laboratories and blood storage facilities

NHS Blood and Transplant supports approximately two million donations annually. Service failure within this estate directly impacts patient safety, hospital supply chains and clinical continuity.


  • The Procurement Challenge

    • The requirement extended beyond standard cleaning provision. NHSBT operates within strict infection prevention and control frameworks, including the Targeted Automatic Barrier System (TABS) and Good Manufacturing Practice (GMP).

    Procurement risk in this context includes:

    • Infection control non-compliance
    • Cross-contamination within laboratory environments
    • Mobilisation risk across multiple live healthcare sites
    • Workforce capability in regulated environments
    • Continuity of service across geographically dispersed locations

    The challenge was to implement a compliant, scalable and stable operating model across 44 active sites.


  • The Delivery Model

    • Samsic established a structured governance framework aligned with NHSBT’s regulatory environment:

    • Mandatory NHS-approved GMP training before site access
    • Ongoing competency refreshers and SOP reinforcement for all roles
    • Dedicated site-level management supported by central Key Account oversight
    • Electronic Compliance Auditing Tool (ECAT) producing site-specific monthly performance data
    • Alignment with NHS TABS protocols to minimise cross-contamination risk

    ESG & Operational Efficiency Integration

    To support NHSBT’s sustainability and cost-efficiency objectives, Samsic introduced Toucan Eco Active, an on-site generated disinfectant solution.

    Toucan works by converting salt and water into a stabilised cleaning solution through electrolysis. This approach:

    • Reduces reliance on traditional chemical disinfectants
    • Cuts single-use plastic container usage by up to 97%
    • Minimises transport and storage requirements
    • Maintains NHS-approved infection control standards

  • Measurable Outcomes

    • Consistent KPI performance exceeding 95%
    90% rating under NHS Trust Assured Barrier System (TABS)
    Reduced chemical consumption and plastic waste
    Stable workforce across a regulated estate
    Contract extension and expansion to additional regions

    Relevance for Constellia Buyers

    For public sector and healthcare procurement teams, this case demonstrates:

    • Mobilisation capability in live, regulated environments
    • Structured compliance management aligned with NHS frameworks
    • Measurable performance reporting and governance
    • Practical ESG integration without compromising infection control
    • Long-term service stability across multi-site estates
