    Why One-Off Testing Falls Short

    A single IAQ assessment captures conditions at one point in time. It cannot account for seasonal variation, occupancy changes, HVAC maintenance cycles, or the gradual deterioration that leads to complaints. For FM teams managing compliance obligations across a portfolio, snapshots create gaps.

    What Ongoing Assurance Delivers

    A structured IAQ assurance programme provides:

    • Trend visibility — year-on-year data that reveals whether conditions are improving, stable, or declining
    • Early warning — identify deteriorating conditions before they generate complaints or enforcement action
    • Compliance confidence — continuous evidence of duty of care, aligned with CIBSE, HSE, and BREEAM/WELL frameworks
    • Budget predictability — fixed-cost programme vs. reactive emergency call-outs
    • Single point of contact — consistent reporting standards and a named account manager who knows your buildings

    Our Contract Tiers

    Green Air Monitoring offers three tiers designed around FM needs:

    • Essential — annual baseline assessment with summary compliance report
    • Standard — biannual assessments with dust monitoring and trend analysis
    • Managed — quarterly verification programme with full ventilation review, continuous trend analysis, and priority reactive response

    Our average FM client tenure is 10–20 years. That longevity reflects what we deliver: reliability, consistency, reduced complaints, and no surprises. We are a proven, low-risk delivery partner — not a one-off testing provider.
